of billing is maintained by auditable reference to hour meters in each helicopter. GCH Aviation operates a job card system to ensure transparency in the billing process. This process starts with the recording of flight time from each helicopter's hour meter that operates only on flight time (not on the ground running). This flight time is verified by our clients at the end of each flying assignment and a copy of the job card is given to our client at that point. From there, the same flight time will appear on the final invoice at the agreed charge rate, ensuring our clients are charged exactly for the helicopter flight time utilised.


GCH Aviation employs full time pilots and part time pilots as required. All pilots hold night ratings and are instructor rated.
