Random 1 Flashcards
What is the difference between transition altitude, level and layer?
Transition altitude: the altitude at or below which the vertical position of an aircraft is controlled by reference to altitudes.
Transition level: The lowest flight level available for use above the transition altitude.
Transition layer: The airspace between the transition altitude and the transition level.
What are the characteristics of gas turbine and jet aircraft that are of particular concern to ATC?
a. High fuel consumption whilst taxiing and holding on the ground.
b. The fuel penalty incurred if climb to cruising level is delayed after take off.
c. The fuel penalty incurred by premature descent to a low level in preparation for approach and landing.
What considerations should be taken for long distance flights?
a) ATC should permit flight to proceed on route/heading with as few turns as possible.
b) To climb to cruising level without restrictions as far as practicable.
c) Avoid excessive delay on the ground.
What are the procedures for arriving aircraft?
Arriving aircraft may be required to report when
• Leaving or passing a significant point or navigation aid, or
• When starting procedure turn or base turn, or
• To provide other information required by the controller, to expedite departing and arriving aircraft.
State when shall APP transfer communication to tower of an arriving aircraft?
Should be effected at such a point, level or time that clearance to land or alternative instructions as well as information on essential local traffic can be issued in a timely manner.
What are the procedures for arriving aircraft when conducting an Instrument approach?
• The approach control unit shall specify the instrument approach procedure to be used by arriving aircraft.
• A flight crew may request an alternative procedure and, if circumstances permit, should be cleared accordingly.
What is ETA for IFR flights?
• Time estimated over designated point, defined by navigation aids, from which instrument approach procedure will be commenced.
Or, if no NAV aid…
• Time will arrive over the aerodrome.
What is the document and chapter for approach control services?
Doc. 4444, CH. 1
Why would an aircraft need to fuel dump?
An aircraft in an emergency or other urgent situations, to reduce to maximum landing mass in order to effect a safe landing.
When shall TWR transfer control of a departing aircraft to APP in VMC condition at aerodrome?
1) before ACFT leaves vicinity of aerodrome.
2) before ACFT enters IMC. or…
3) at a prescribed point or level
as specified in letters of agreement or ATS unit instructions.
When shall TWR transfer control of a departing aircraft to APP in IMC condition at aerodrome.
1) Immediately after ACFT is airborne,
or
2) At a prescribed point or level,
as specified in letters of agreement or local instructions.
What are the procedures for arriving aircraft when Holding?
If an ACFT in an approach sequence request holding:
- The request to hold shall be approved.
- Clear ACFT to an adjacent fix for holding or placed at the top of the stack . (holding sequence).
- Co-ordination shall be effected with any adjacent ATC unit, as required.
What are the procedures for arriving aircraft when conducting an Approach sequence?
The approach sequence shall be established in a manner which will facilitate arrival of the maximum number of aircraft with the least average delay.
What are the procedures for arriving aircraft in regards to expected approach time?
- Determined for an arriving ACFT subjected to a delay of 10 min or more or such time as determined by the appropriate authority.
- Transmitted as soon as practical.
- Revised EAT shall be transmitted without delay whenever it differs 5 min or more. (or less when determined by the appropriate authority)
- Transmit by most expeditious means if 30 min or more holding.
What should be coordinated between ATC and the flight crew, prior to dumping fuel within a CTA?
a) The route to be flown.
If possible, should be clear of cities and towns, preferably over water and away from areas where thunderstorms have been reported or are expected;
b) The level to be used.
should be not less than 6,000 ft. and…
c) The duration of the fuel dumping.
