A11.14 Flights over urban areas
Pipelines running through urban areas should wherever possible be inspected from the ground. Where aerial inspection is essential it should be conducted at a minimum altitude approved by local civil aviation authorities.
When operating single-engine aircraft, or multi-engine aircraft unable to sustain flight on one engine, pilots will select a flight path that provides a safe emergency landing area, avoids damage to third parties or facilities on the ground and that provides opportunity for a safe emergency land-ing.
Operators will designate the preferred flight-path to be used if flights are conducted routinely over the same congested area.
A11.15 Landings en-route (helicopters only)
During the flight the observer will take a note of construction work, or any other activity near the pipeline which could affect its integrity, and will report events to the pipeline owner to follow up on the ground. However, if he judges that urgent action is required (for example, a trench converg-ing on the pipeline) he may request the pilot to land nearby so that he can talk to persons on-site. The operator should therefore have a section in his Operations Manual on unplanned landings to include guidance on the justification for such a landing, landing site selection, informing base or ATC of the intention to land, and recording the event. Pilot training and line-checking should include unplanned landing procedures.
