What is needed to cross an airway?
To be under the control of an approved ATC Radar unit, or under positive ATC clearance.
What is the purpose of Radar Corridors?
Established to help with the crossing of airways in complex airspace.
What is required to cross an airway in IFR?
A flight plan must be filed before departure or when airborne
Request to cross AT LEAST 10 mins BEFORE arrival at the intended crossing point. Call must contain:
Identification Aircraft type Position and heading Level and flight conditions Position of crossing Requested crossing level Estimated time of crossing
In VFR, what is the minimum notice ATC should be given of a request to cross an airway?
5 mins
