Class D Airspace Flashcards
What is the vertical range for most of Class D airspace?
Surface to 2,500 AGL
What facility is found in a Class D airport? What is not?
Class D airports have an operating control tower
Class D airports usually do not have a radar
What is the normal lateral area for Class D airspace?
Most are individually tailored
Most common circular area with a radius of 4 NM
Extensions are present when necessary for nearby airports or to accomodate an instrument approach or departure procedure
What are the entry requirements for Class D airspace?
Two-way radio communcations must be established before entering
“(Callsign standby)” permits entry into the Class D
Controller may advise an aircraft to “Remain outside Class D”
Similar to Class C, what are the speed limits in/surrounding Class D airspace?
250 KIAS below 10,000 feet
Below 2,500 feet AGL within 4 NM of the primary airport of Class D prevents any aircraft from exceeding 200 KIAS
Any speed between 200 KIAS and 250 KIAS must be assigned by ATC (e.g. 230 KIAS)
Does Class D airspace have weather reporting services?
Class D airspace must have weather reporting
What type of airspace does Class D airspace revert to when the primary airport’s tower closes?
If continuous weather reporting is maintained after the tower closes then the airspace reverts to Class E (controlled)
If continuous weather reporting is not available after the tower closes then the airspace reverts to Class G (uncontrolled)
What is the best resource to determine what type of airspace a Class D airspace reverts to when its primary airport tower closes?
The Airport Facilities Directory (A/FD) shows which type of airspace will exist after the tower closes
