InstrumentApproachProcedure


             urn:aero:airm:1.0.0:LogicalModel:Subjects:AirspaceInfrastructure:RouteAndProcedure:InstrumentApproachProcedure

A series of predetermined manoeuvres by reference to flight instruments with specified protection from obstacles from the initial approach fix, or where applicable, from the beginning of a defined arrival route to a point from which a landing can be completed and thereafter, if a landing is not completed, to a position at which holding or en-route obstacle clearance criteria apply.
