Domestic Operations Flights conducted between airports within the territories of one state. Equivalent Terms: Domestic Flights Driftdown The descent of a multi-engine aircraft to a planned (or predetermined) altitude after an en-route failure of one engine. Driftdown (Altitude) The highest altitude, based on a planned aircraft weight, that can be maintained by a two engine aircraft after an en-route engine failure. Driftdown (Performance) The minimum level of aircraft performance, achieved by limiting the takeoff weight as a means to limit the en-route weight, which maximises the driftdown altitude in critical terrain areas. For critical terrain areas, driftdown performance is maximised in order to clear all terrain along the intended route by a margin acceptable to the Operator or Authority. Dual Inspection See Independent Inspection. Equivalent Terms: Independent Inspection Dye Penetrant Inspection Non-Destructive Testing method involving Liquid Dyes and Ultraviolet Light media.
