A11.4 Aircraft configuration
For long-term pipeline patrol operations, the following should be installed:
a) Collision avoidance systems with active transponder interrogation, providing verbal and/or visual positional data on the target aircraft in high density areas or where other low level traffic may present a hazard.
b) Automated engine monitoring systems for all single-engine aircraft. c) Landing lights converted to pulse light configuration (for aeroplanes wing tip pulse lights) in high-density areas. d) Climate controlled cabin for all operations in temperatures below 15°C and for long-term operations where temperatures are routinely above 32°C.
e) Survival kits should include a portable emergency beacon/radio (EPIRB). f) High Intensity Strobe Lights (HISL)/pulse or forward recognition lights should be fitted
to the aircraft.
g) The aircraft should be painted in a high visibility paint scheme with appropriate markings.
h) The operator should be encouraged to fit High Visibility Blades for helicopters if approved
for the model.
i) Radar Altimeter (Radalt) with audio and visual alert or Automatic Voice Alerting Device (AVAD), where available for the aircraft model, is recommended to ensure that the selected height AGL is maintained.
j) Obstruction avoidance equipment/software to provide an active indication of cell towers, antennas, wires, buildings, terrain, etc. when available for the aircraft model should be con-sidered.
A11.5 Aircraft maintenance for long-term operations
a) Where continuous airworthiness programmes have been published by the manufacturer, aircraft should be maintained in accordance with those programmes.
b) Engine trend monitoring programmes should be implemented for all single-engine aircraft. In the absence of other guidance, a programme similar to that described in FAA Advisory Circular 20-105B should be considered.
A11.6 General pilot requirements
The need for a qualified pilot is extremely important. The following should be considered when selecting for a pipeline contract:
a) The basic operation of pipeline patrol requires a division of attention between flying the aircraft, looking for traffic and observing the pipeline right of way. It is not the best place to use low-time pilots.
b) Patrol pilots may fly long hours often as a single pilot. The pilot should have a history of fol-lowing all rules, and be self-motivated. c) Pilots must have a strong working knowledge of route terrain, and have a good understand-ing of local weather conditions. d) Each Operator should establish the procedures to be used by the aircrew in the performance of their duties to include but not limited to cockpit procedures and crew responsibilities. e) Each Operator should establish a ‘sterile cockpit’ rule covering as a minimum: key alti-tudes/flight phases, restriction of unnecessary conversation and paperwork.
A11.7 Pipeline patrol specific pilot role experience
In addition to experience requirements contained in Appendix 5 the following requirements are recommended for all aircrew: a) Successful completion of a pipeline route check for the route to be flown (unless for a newly established route). b) Basic instrument experience. c) 50 hours in command patrol survey time in the previous six months. d) 10 hours on the contract aircraft type conducting pipeline operations within the preceding 90 days, or successful completion of a pipeline line check within the preceding 90 days.
