Dispatch reliability
Dispatch reliability is the percentage of scheduled departures an aircraft type or fleet makes on time without a technical delay or cancellation. Manufacturers quote figures above 99% for mature types; the Gulfstream and Falcon fleets and the Citation family have long records near 99.8%. For a charter customer, the operator's own reliability record matters more than the type's: ask how often flights are moved to a substitute aircraft and what the recovery plan is if the jet goes technical at an outstation. For an owner, dispatch reliability drives how often you end up chartering a backup, which is a hidden but real cost of owning a single aircraft.
