ATC Flashcards
What is ATIS?
Automatic Terminal Information Service
Audible broadcast which includes current airport weather conditions and certain operational information, such as active runways and instrument approaches in use, and cautionary information. Reduces radio frequency congestion by allowing pilots to self brief on relevant information so that ATC controllers don’t have to repeat the same information to all departing and arriving pilots.
What does EDCT mean?
Expect Departure Clearance Time
An estimated delayed departure time, due to a GDP (Ground Delay Program).
Aircraft is expected to plan taxi to be airborne by this time.
What is EFC?
Expect Further Clearance
Issued as part of airborne holding instructions.
Time to expect a further clearance (release from hold)
Used to depart hold in event of radio communication failure.
What does clearance void time mean?
Included as part of an IFR clearance at non tower controlled airport.
Aircraft must be airborne by the issued void time, or IFR clearance becomes void.
New IFR clearance must be received.
What is a ground stop?
A ground delay program in effect for destination in which a delayed departure time cannot be determined. All inbound traffic must hold at the departure airport until further notice.
What is an ATC flight plan?
Proposed details for a future flight for ATC consideration.
IFR flights require flight plan be filed at least 30 minutes prior to proposed departure time. Pilots receive an IFR clearance prior to departure based on flight plan, which may be as filed, or with changes as assigned by ATC.
What is a transponder / ADS-B?
Automatic Dependent Surveillance Broadcast
Aircraft transmitter equipment to enable aircraft to appear on ATC radar displays.
Any combination of four digits 0-7 may be issued by ATC for a unique code per aircraft.
