Chapter 4: Air Traffic Control Flashcards
What are ARTCCs and why were they established?
A) Air Route Traffic Control Centers
B) These centers are established primarily to provide air traffic service to aircraft operating on IFR flight plans within controlled airspace, and principally during the en route phase of flight.
Why are control towers established and what other responsibility can be delegated to them?
A) Towers are established to provide for a safe, orderly and expeditious flow of traffic on and in the vicinity of an airport.
B) Towers can also provide for the separation of IFR aircraft in the terminal areas, if so delegated.
What are the services/responsibilities of a Flight Service Station (FSS)?
Flight Service Stations (FSSs) are air traffic facilities that provide:
A) Pilot briefings
B) Flight plan processing
C) En route flight advisories
D) Search and rescue services
E) Assistance to lost aircraft and aircraft in emergency situations
F) FSSs also relay ATC clearances
G) Process Notices to Air Missions
H) Broadcast aviation weather and aeronautical information.
What is a communications release of IFR aircraft landing at an airport without an operating control tower? What is important to note during such a transition?
A) Aircraft operating on an IFR flight plan, landing at an airport without an operating control tower will be advised to change to the airport advisory frequency when direct communications with ATC are no longer required.
B) Towers and centers do not have nontower airport traffic and runway in use information. The instrument approach may not be aligned with the runway in use; therefore, if the information has not already been obtained, pilots should make an expeditious change to the airport advisory frequency when authorized.
What information does Approach Control Services for VFR Arriving Aircraft include? Where can and should you get this information as opposed to waiting for the tower to tell you?
A) Wind, runway, and altimeter setting at the airport of intended landing
B) ATIS, if available.
What is a MULTICOM frequency and when is it used?
The MULTICOM frequency is 122.9 and is used as a self-announce frequency in absence of a Control Tower, FSS, or UNICOM.
What other things may a CTAF serve as?
UNICOM, MULTICOM, FSS, or Control Tower.
What is the Helicopter air-air frequency?
123.025
May you use UNICOM for ATC purposes? And if so, what purposes?
Yes
A) Revision to proposed departure time.
B) Takeoff, arrival, or flight plan cancellation time.
C) ATC clearance, provided arrangements are made between the ATC facility and the UNICOM licensee to handle such messages.
