. 
Survival pack suited to the operating environment.

A10.3 Personal equipment standards
Personnel involved in geophysical flying operations must wear appropriate clothing. All occupants of an aircraft conducting geophysical flying must have as a minimum:
. 
Flying helmet meeting industry safety standards.

. 
Non-synthetic or fire blocked/retardant trousers and shirt.

. 
Cotton undergarments.

. 
Robust shoes.

. 
Life jackets (and immersion suits depending on water temperatures) – if flight is outside safe auto-rotative/gliding distance from land.

. 
Personal emergency locator beacon.

A10.4 Minimum crew
A pilot and geophysical operator is the minimum acceptable crew for airborne geophysical surveys. Single crew operations (i.e. the pilot as the sole occupant) are not permitted unless survey equipment can be operated automatically without significant inputs from the pilot during flight.

A10.5 General pilot experience

The following experience requirements are generic to both fixed and rotary wing operations above and below 5,700 kg (12,500 lbs). Each requirement should be satisfied in addition to the specific pilot experience requirements detailed in Section 4.3 of this guide and summarised in Appendix 5.
Captain
Successful completion of a geophysical training programmeincluding, where applicable, a mountain flying course:
. 
300 hours experience in airborne geophysical operations (including 100 hours in Command or In-Command-Under-Supervision);

. 
50 hours Command (or ICUS) on geophysical survey in the contract aircraft type;

. 
10 hours Command (or ICUS) in the contract aircraft type conducting geophysical operations within the preceding 90 days, or successful completion of a geophysical line check of at least two hours (excluding ferry time) within the preceding 90 days.

Co-Pilot (if carried)
Successful completion of geophysical training programme including, where applicable, a mountain flying course:
. 
10 hours on low level survey operations;

. 
Manipulation of the flight controls at survey height by a co-pilot will be restricted to those flights where the aircraft captain is an approved check and training or supervisory captain.

A10.6 Pilot flight & duty times
Due to the fatiguing nature of geophysical flying the following flight hour limitations are to be observed:
Single Pilot Operations
. 
5 hours per day on actual survey (transit time excluded);

. 
34 hours in any consecutive 7 days (inclusive of transit time);

. 
overall 28 day limits as specified in Section 5.6 of this guide;

. 
a minimum of 24 consecutive hours free of duty during any seven consecutive days.

Two Pilot Operations
. 
7 hours per day on actual survey (transit time excluded);

. 
34 hours in any consecutive 7 days (inclusive of transit time);

. 
overall 28 day limits as specified in Section 5.6 of this guide;

. 
in addition to the above limitations, aircraft crews operating internationally must comply with flight and duty limitations of the country in which they are operating if so required by that country’s aviation regulatory authority.

A10.7 Minimum survey height
The following IAGSA guidance is to be adhered to:
The maximum clearance height possible should be specified consistent with the objectives of the survey to be flown. If a survey is to be flown at less than 100m (328 ft) it should be flown after con-ducting a detailed risk analysis in accordance with an internationally recognised procedure such as the IAGSA risk analysis procedure referred to above, considering, but not limited to:
