P1177 Helicopter-borne Geophysical Survey, Mexico – October 2011

 

C6. Flight Specifications

 

C6.1.    Flight Lines

 

Line directions and line spacings are specified in Schedule B, but may be subject to change and will therefore be confirmed between MPX's and Client's representative immediately prior to the commencement of the survey operations. Any such changes will not unduly effect efficient collection of data.

 

C6.2.     Terrain Clearances

 

Optimum terrain clearances for the helicopter and instrumentation during normal survey flying are:

 

Helicopter	-	70 metres
Magnetometer	-	70 metres
Gamma Spectrometer	-	70 metres

 

The pilot will make every sensible effort to fly accurate terrain clearances, however, it is accepted that aircraft terrain clearance may vary, based on the pilot's judgement of safe flying conditions around man-made structures or in rugged terrain where aviation laws may require a higher flight altitude. Taking into account the above safety considerations and pilot judgement, MPX will do its best to conduct the survey with an altitude tolerance of +-20m, trying not to exceed +/- 20m over a distance of more than 1 km.

 

C6.3.     Airspeed

 

Normal aircraft airspeed will be approximately 70kts, but this may vary in areas of rugged terrain. With a sampling rate of 1 second, spectrometer measurements are acquired approximately every 36 metres along the survey line. With a sampling rate of 10 times per second, magnetometer measurements are acquired every 3.6 metres along the survey line.

 

C6.4.     Magnetic Diurnal

 

Flight lines, or portions thereof, will be reflown if the magnetic diurnal exceeds 12 nT in a straight-line chord over 5 minutes. Survey data acquisition will be stopped altogether in the case of severe magnetic diurnal activity.

 

C6.5.      Reflights

 

Reflights will be attempted whenever survey lines or part survey lines are noted in the field to be beyond the agreed tolerances.

 

The flight lines will not deviate from the intended flight path by more than 50% of the nominal line spacing over a distance of more than 1 km. All reflights will cross a minimum of two tie lines.

C7. Survey Instruments

 

C7.1.     Airborne High Sensitivity Magnetometer

 

The magnetic sensor that will be utilized for the survey is a Scintrex CS-3 high resolution cesium split-beam total-field magnetometer (see figure 4), which will be installed in a fixed boom. The sampling rate is ten (10) times per second with an in-flight sensitivity of 0.002 nanoTesla (nT). Aerodynamic magnetometer noise is +/- 0.01 nT. The sensitivity of the magnetometer will be recorded at 0.002 nT when operated at a sampling rate of 0.1 seconds.

 

 

Figure 4: Scintrex CS-3 Cesium Magnetometer

 

A Cesium vapour magnetic sensor is a miniature atomic absorption unit, producing a signal whose frequency (Larmor frequency) is proportional to the intensity of the ambient magnetic field. The unit consists of three main elements; a Cesium vapour lamp, an absorption cell, and a photosensitive diode.

 

These components are mounted along a common optical axis within the sensor housing. The electronic support system is mounted at the rear of the towed bird or 1.5m from the sensor in a fixed boom configuration, transmitting the Larmor signal to a counter in the data acquisition system then converted the signal to magnetic field strength in nanoTeslas.

P1177 Helicopter-borne Geophysical Survey, Mexico – October 2011

 

C7.2.      PC-based Data Acquisition System

 

Geophysical, navigation and altimeter data will be recorded by the AGIS data acquisition system in the helicopter, at various recording rates ranging from 10 Hz to 1 Hz (ten times per second to once per second).

 

Data will be displayed on the computer LCD display as traces, in simulation of a chart recorder's traces, for verification of functionality and quality.

 

On completion of flying, the data recorded will be copied to back-up CD-ROM and transferred to the Field Workstation (described below) where the data will be retrieved, verified and processed.

 

All geophysical, positional, and ancillary sensor data measured during the survey are recorded digitally using a high-speed, precision data acquisition system. Survey data can be monitored on a number of operator-selectable strip-chart traces available on the operators display. The system does not produce paper charts.

C7.6.      GRS-10 Spectrometer

 

Pico-Envirotec GRS-410 multi-channel gamma-ray spectrometer with 16.8 litres “downward looking” NaI sensor, and 4.2 litres “upward looking” NaI sensor will be installed on the helicopter for the survey.

The GRS-410 is a self-stabilizing spectrometer, and tracks and corrects for the spectral drift by following a spectral peak, typically thorium. The standard regions of interest, as listed below, will be recorded and processed. The 256 channel digital data will be recorded and provided to Client. An example of the standard regions of interest that will be recorded, with window in MeV, is given in the table below:

C7.7.      Ground Support Equipment

 

The base station and in-field data processing quality control and quality assurance (QA/QC) system will consist of the following equipment:

 

·

A Field Workstation, comprising a Pentium PC, a printer and full data processing

software.

·

A Gem Systems GSM-19TW magnetometer base station, with digital recording, will be utilized on this survey. This magnetometer will be operated continuously throughout the survey operations. The base station will be synchronized with the airborne system by GPS time. The resolution of this magnetometer is 0.1 nT. During survey operations, the magnetometer will sample at a rate of once a second. Every effort will be made to ensure that the magnetometer sensor is placed in a location with a low magnetic gradient. In addition, it will be sited away from moving ferrous objects, such as vehicles, and electric power transmission lines, such that these sources of man-made noise will not exceed 0.1 nT

·

A complement of spare parts and test equipment

C8. Instrument Checks, Tests and Calibrations

  

C8.1.     Manoeuvre noise

 

As the magnetic gradient sensors, installed in the single sensor fixed boom, are still within the magnetic effect of the aircraft structure, tests will be conducted prior to the survey to determine the effects of helicopter pitch, roll and yaw. The tests will be completed at high altitude (ideally 10,000 ft above terrain AGL) over an area of low magnetic gradient by carrying out ±10^o rolls, ±5^o pitches and ±5^o yaw manoeuvres flown over periods of at least 4-5 seconds in the same direction as the flight and tie lines. A compensation Figure-of-Merit (FOM) for the helicopter will be calculated by summing the peak-to-peak amplitudes of the twelve magnetic signatures. The FOM is used as an indicator of performance and should remain below the industry standard value of 2 nT for the sensor mounted in a helicopter stinger/boom.

 

C8.2.     Magnetic Heading Effect

 

The magnetic heading effect will be determined prior to the survey by flying a cloverleaf pattern oriented in the same direction as the survey lines and tie lines at high level in an area with low magnetic gradient. At least two passes in each direction will be flown in order to obtain sufficient statistical information to estimate the heading error. The heading error will be determined at the beginning of the survey, and again if there are any modifications or additions to the aircraft or the equipment installed in it.

P1177 Helicopter-borne Geophysical Survey, Mexico – October 2011

 

C8.3.      Lag Tests

 

A lag test will have been performed before the survey to ascertain the time difference between the instrument readings and the operation of the GPS System. Test lines are flown in two directions at survey altitude across distinct anomalies.

 

These lag tests were carried out before the start of survey production flights, and will be repeated after any major survey equipment alteration or replacement has been made.

 

C8.4.     Altimeter Calibration Checks

 

Checks of the radar altimeter calibration will have been undertaken before the survey, after installation of equipment in the aircraft. The calibration is determined by comparing the radar altitude with a suitable reading from the GPS system during a radar “stack” over the landing pad or a suitable level area where the height above sea-level (ASL) is accurately known.

 

C8.5.     Gamma-Ray Spectrometry checks and tests

 

a. Altitude Attenuation Coefficient

Determination of the altitude attenuation coefficient will have been undertaken prior to the survey by flying a test line at various altitudes from 60 m up to 250 m at 30 m intervals above the test line. An airborne calibration range test line should have the following features: (a) Be relatively flat; (b) Have uniform concentrations of K, U, and Th; (c) Be close to a body of water for measurement of background (if a suitable body of water exists); (d) Be free of flight restrictions; (e) Be easy to navigate; (f) Be about 8 km long, equivalent to about 150 s flying time at 50m/s; (g) Have no hills within about 1 km of the flight line. The results of this check will be digitally recorded, and will be compiled into tables and graphs to be presented to the Client in the final report.  

 

b. Cosmic Window Calibrations

Cosmic window calibrations will have been carried out prior to the survey. This is normally performed by flying at various altitudes over the ocean or any large body of water (250m and from 1,500 m up to 3,500 m at intervals of 300 m), with each altitude flown for a minimum of 10 minutes. If a large body of water does not exist close to the survey area, this test can be performed over the ground. The average values of the counts measured in each of the 4 windows (TC, U, Th and K) will be compared against the average counts for the cosmic window at each of the altitudes where measurements are made. The results of this calibration will be digitally recorded, and will be compiled into tables and graphs to be presented to the Client in the final report.

P1177 Helicopter-borne Geophysical Survey, Mexico – October 2011

 

C8.6. Gamma-Ray Spectrometry Limitations

 

The presence of powerlines and/or steep topography may compromise the quality of the radiometric data. We will proceed and try to acquire good radiometric data, but we will not be able to guarantee the accuracy of data obtained at large heights above the terrain (100m+).  Ideally the terrain clearance should be maintained at 70m, but topography and safety considerations may be limiting factors for this airborne survey.  For example, the presence of electrical powerlines forces the pilot to fly at greater heights in order to guarantee the safety of all personnel onboard.   

 

C9.     Safety Procedures

 

For the duration of the work, MPX will ensure that the work performed is carried out with the utmost regard for safety, and that all its personnel are fully conversant with safety standards considered normal in the aviation industry. MPX’s Project Manager will review and establish safety procedures with the Pilot and will specifically ensure that all crew members are aware of emergency and radio communications procedures.

 

During the course of the Survey, MPX shall keep the site of any refuelling areas free of accumulations of waste materials, rubbish or garbage and upon completion of the Survey shall remove all tools, fuel, fuel drums, surplus materials, rubbish and garbage and leave the refuelling sites in a clean condition.

 

The pilots are ultimately responsible for the safety of each flight but, if at any time anyone in the aircraft has a question about location, intention, or safety, the pilot must use every effort to address the concerns and resolve the question, without compromising the safety of the flight. If a crewmember is not satisfied with the pilot’s response or actions the crew member may request that the pilot terminate the flight and return to the base of operations. The pilot will comply with this request and any disagreement or discrepancy will be resolved on the ground.

 

The Project Manager will conduct weekly safety / operations briefings with the crew. These briefings will consist of the following:

 

·

Review of safety and emergency equipment on board the aircraft

·

Review of emergency procedures and available emergency services

·

Review of previous weeks work to smooth out any rough points and/or suggest improvements

·

Review of project status and operating plans for the coming week

 

Safety is a very important aspect of any of MPX’s operations, and nothing will be done to compromise aircraft safety. A copy of our Health, Safety and Environment (HSE) Manual was previously provided.

 

MPX is a member of the International Airborne Geophysics Safety Association (IAGSA) www.iagsa.ca and all our survey operations are conducted to the exacting safety standards of this organisation.

SCHEDULE D

QUALITY CONTROL/ DATA PROCESSING

  

D1.     QUALITY CONTROL

 

Daily quality control of newly acquired airborne data will be undertaken in the field by MPX’s technologist, and will also be transmitted on a daily basis via the internet and an ftp-site to MPX’s data processing facility in Markham. Quality control information may then be confirmed by MPX and relayed back to the field crew on a regular basis.

 

D2.     DATA PROCESSING

 

D2.1     Topographic Base and Title of Survey Area

 

A topographic base will be prepared for the survey areas from a DTM (or by scanning the relevant topographic maps) covering the survey area, and plotting the major features (large lakes, major rivers, towns, etc.) as background on to the geophysical maps. All title blocks and surround data appearing on the base maps will be machine drafted using CAD techniques.

 

D2.2      Flight Path Compilation

 

The flight path will be derived from the differentially corrected GPS navigation data.

 

D2.3       Magnetic Data

 

The magnetic data are first corrected for diurnal variations, lag and heading effects. The data will be further analyzed using tie-line data. Control-line levelling is applied to the tie-line data. Final micro-levelling techniques are then applied to the data to remove minor residual variations in profile intensities. Located and gridded data are generated for the final processed magnetic data.

 

The semi-automated magnetic data levelling system includes:

 

1.

Tabulation of magnetic data at flight line/tie line intersections, along with flight altitude data;

2.

Network analysis of intersection data, based on minimizing square mean root of the differences and closure errors, to obtain suggested leveling adjustments;

3.

Manual analysis of computer suggested corrections, based on magnetic gradients at the intersections and the flight altitude differences;

4.

Application of leveling corrections; and

5.

Revision of leveling corrections using imaging techniques.

P1177 Helicopter-borne Geophysical Survey, Mexico – October 2011

 

Any residual, small scale, in-between tie-line leveling errors are removed using micro-leveling techniques. The resultant gridded magnetic data will be of high image quality and the corresponding located line data will also be prepared.

 

The regional International Geomagnetic Reference Field (IGRF) 2011 will be computed (based on 2010 calculated model) and removed from the data using the GPS location at each observation point and epoch appropriate to the current survey.

 

The total field magnetic data and residual magnetic data grids will be produced using a minimum curvature algorithm. The reduced-to-the-pole or reduced-to-the-equator grid will be calculated using the residual grid.

 

The reduced-to-the-pole or reduced-to-the-equator total field magnetic data may be subjected to a variety of filtering techniques to yield maps and/or images of the following:

 

·

calculated vertical and/or horizontal gradient

·

second vertical derivative

·

magnetic susceptibility

·

upward/downward continuations

·

band pass filtering

·

analytical signal

 

All of these filtering techniques improve the recognition of near-surface magnetic bodies or features, with the exception of upward continuation, which provides a regional view.

 

D2.4       Radiometric Data

 

The reduction of radiometric data followed standard processing steps as outlined in the recommendations of IAEA-TECDOC-1363 (Vienne) – Guidelines for radioelement mapping using airborne gamma – ray spectrometry data.

The corrections to the gamma-ray spectrometry data involved:

1.

Correction for system dead-time,

2.

Aircraft background and cosmic correction,

3.

Compton (Stripping) correction,

4.

Attenuation correction,

5.

Convert to radioelement

D2.5         Presentation of Data

 

D2.5.1.          Gridding

 

The corrected geophysical data from each survey line will be interpolated between survey lines using a random gridding method to yield x-y grid values for an expected standard grid cell size of 0.25 cm at the mapping scale. 

 

D2.5.2.          Contour and Colour Images

 

Computer generated contour images of the aeromagnetic data are created from the grid and will be plotted.

 

Colour images are produced by interpolating the grid down to an appropriate pixel size. The parameter is then incremented with respect to specific amplitude ranges to provide solid colour "contour" images. Black-line contours are superimposed on the colour images. Solid colour images of the total magnetic field are particularly useful in defining the lithology of the survey area.

 

Monochromatic or colour shadow images can be generated by utilizing an artificial sun to cast shadows on a surface defined by the geophysical grid. There are many variations in the shadowing technique. These techniques may be applied to total field or enhanced magnetic data, magnetic derivatives, etc. Of the various magnetic products, the shadow of the enhanced magnetic parameter is particularly suited for defining geologic structures with crisper images and improved resolution.

SCHEDULE F

IAGSA SURVEY CONTRACT ANNEX

1.1 Introduction

The party contracting the airborne geophysical survey (Company) and the party supplying the services (Contractor) each has a Duty of Care to ensure that the survey is carried out safely. The Contractor shall have a Safety Management System and ensure that flight operations meet or exceed regulatory and Company safety requirements.

 

The provisions contained herein have been prepared by the International Airborne Geophysics Safety Association (IAGSA) and have been drawn from IAGSA’s Safety Policy Manual. They represent those provisions normally appropriate to airborne surveys. Additional background and implementation details may be found in the Safety Policy Manual and the Contractor should reference the manual as necessary.

 

The provisions in this Annex are not exhaustive and may be amended or extended as necessary in accordance with the survey specific risk assessment. 

 

1.2 Job Safety Analysis

The contractor and where applicable the aircraft operator will complete a Job Safety Analysis (JSA) for review and acceptance by the Company before awarding a contract. The JSA should include, but not be limited to, the provisions described in this Annex and IAGSA’s Guide to Risk Analysis. (Safety Manual Appendix V) Provisions and practices shall be developed and documented to mitigate the effect of identified hazards. 

 

1.3 Survey Height

Based on pilot reaction times and other factors, it is generally acknowledged that the lower the survey is flown, the higher the risk associated with the operation. Current industry practice often dictates low clearance heights. To achieve a safe survey height; the Company will specify the maximum clearance height possible, consistent with the objectives of the survey to be flown; and the Contractor will conduct a risk analysis that emphasizes the risk factors which pertain to survey height . These factors shall, as a minimum, include the following:

 

Terrain relief and elevation above the trees or the tree canopy
aircraft performance
aircrew flight and duty times
prevailing weather conditions
anticipated density altitude
pilot experience and recency
planned flight speed

1.4 Turning Procedures

All turns at low-level should be limited to a maximum angle of bank of 30 degrees and be done at a constant altitude. No climbs or descents should be carried out during the turn. If the terrain or survey height dictates that a climb is necessary the aircraft should be climbed to the required height prior to commencing the turn and any descent back to survey height should be done after established in a wings level attitude.

 

1.5 Minimum Safe Survey Speed

The minimum safe survey speed is to be the greater of: 130% of clean stall speed (Vs); 110% of best single engine rate of climb speed (Vyse, if applicable), or minimum safe single engine speed (Vsse, if published). This minimum speed shall be observed even when exchanging airspeed for altitude during a climb and should be raised as necessary to account for local conditions such as turbulence and gusty winds.

 

1.6 Performance Monitoring

Performance parameters, including aircraft speed, height above terrain and drape, will be periodically reviewed using data collected during the survey. Deviations below minimum survey speeds and minimum height will be investigated and corrective action taken to ensure that safety margins are not compromised. The frequency of review should be such as to identify any discrepancies as early as possible. (IAGSA’s Technical Committee is working on a protocol that will provide practical guidance for; identifying the kinds of data that should be available; how often it should be sought; and what to do when hazardous flying is detected or suspected) 

 

1.7 Flight Following

The operator will have in place for all survey flights a flight following system that includes scheduled position reports, position logs maintained on the ground, operational flight plans and overdue/emergency response procedures. If the survey is being conducted in an area where it would be difficult to find a downed aircraft or ground based communication facilities are severely limited the parties should consider using a satellite based tracking system in conjunction with position reports. 

 

1.8 Survival

In the event that the aircraft’s survival kit is destroyed in a crash, each crew member carry on his/her person essential survival items that include a personal locator beacon, means to start a fire, a small knife and a signal mirror. 

 

1.9 Underwater Escape Training

If the survey is over water, all crew members shall have undergone underwater escape training at an acceptable training facility during the past three years. This training should have also cover sea survival and use of emergency equipment.

1200 hours in any calendar year.

 

The maximum duty time in any one day shall not exceed 14 hours.
The maximum duty time shall not exceed 60 hours in any 7 consecutive day period.
The pilot shall have a minimum of 2 days rest within a 14 day period. These may be taken separately or

together. If taken separately, one day of rest shall be defined as 30 consecutive hours free of duty.

 

1.14 Fuel

The pilot shall take all necessary measures to ensure that any fuel loaded onto the aircraft is not contaminated. (Detailed procedures are outlined in IAGSA’s Safety Policy Manual).

  

1.15 Use of Helmets

Use of helmets is to be considered on a case by case basis and where they are judged to enhance pilot safety, helmets shall be worn. 

 

1.16 Night Surveys

To conduct a night survey the aircraft must be IFR certified and equipped with at least two independent and dissimilar IFR certified navigation systems that can be used in the survey area. The survey shall be flown at least 1000 feet above all obstacles within the operational area and a 10 nautical mile buffer around the operational area.
