Air traffic control
1. What is the function of the Tower?
The Tower issues information to aircraft under its control to achieve a safe, orderly and expeditions flow of air traffic on and in the vicinity of the aerodrome with the object of preventing collisions between: Aircraft flying in the traffic circuit around an aerodrome; Aircraft operating on the maneuvering area; Aircraft landing and taking-off; Aircraft and vehicles operating on the maneuvering area; Aircraft on the maneuvering and obstructions on that area
2. What is a maneuvering area used for?
That part of an aerodrome is used for take-off, landing and taxying, excluding aprons
3. How can the Aerodrome Control be subdivided?
Air Control(RW) and GMC(Apron, TWs). Кроме того есть Approach Control and Area Control Center(ACC)
4. What kind of information is broadcast on ATIS frequency?
QNH, runway-in-use, wind direction and speed, temperature, TW closures, unserviceabilities
5. How is the traffic circuit divided? How many parts does the traffic circuit have?
crosswind, downwind, base, final approach
6. What is the standard circuit-joining procedure?
It is to arrive overhead the field at 2000 ft and descend to 1000 ft on the dead side - the one opposite the live downwind leg
7. What is an orbit?
It is three sixty turn (360) (anti)-clockwise always away from final
8. What do you know about the vortex wake? Why may it be dangerous?
This is a rapidly moving cylinder of air from each wingtip which can be strong enough to overcome the control forces of a following aircraft and invert it
-9. How can fuel burn be minimized on ground?
Aircraft should first require permission to start engines so that ATC can warn of any delays and thus minimize fuel burn. The aircraft should be given an Approved Departure Time ( known as «slot»
10. What are SIDs designed for?
to minimize conflict between arriving and departing aircraft
11. What does ACC stand for? Describe the ACC’s basic function.
Area Control Center issues route clearances based on the information in field Flight Plan
12. What is squawk/SSR code?
It is a transponder code
13. Define procedural separation. How is it achieved?
by calculating time the AFT pass each reporting point in advance
14. Why does an ATC controller need actual time over each reporting point?
To ensure that the required time separation from preceding aircraft is maintained
15. What is route clearance based on?
based on the information in field Flight Plan
16. What kind of information does advisory service issue?
It does not issue clearances but only advisory information and it uses the words «advise» and «suggest» when an action is proposed to an aircraft
17. In what case may an ADR revert to full airway status?
when crossing a national or FIR/UIR boundary
-18.What does the phrase ‘No delay expected’ mean?
19. What does Approach Control ensure? At what point is AFT transferred from Area to Approach Control?
at specified release point, a position, or level agreed on the telephone by the two controllers before the aircraft comes onto the Approach frequency
20. Why is it necessary to put AFT into the holding pattern?
to organize sequence for landing and take-off and reduce risk of any delays
21. Where are holding patterns published?
in aeronautical chart or approach plates
22. What is the decision height?
Is a specified altitude or height at which pilot decides to go around or land
23. Define threshold.
It is a beginning of RW
24. Decode
FIS-flight information service;
ADR-Advisory route;
ETA-Estimated time of arrival;
ETD-Estimated time of departure;
EET-Estimated elapsed time;
EAT-expected approach time;
PAR-Precision approach radar;
TW-Taxiway.
25. What ATC units control AFT flying en route?
ACC
26. Which AFT is the priority given to?
in emergency, hospital flights, specific operations
-27. What is Expected Approach Time?
28. What is STAR?
Standard Terminal Arrival Routes
