ATC Seperation Vertical Flashcards
Vertical separation is obtained by?
Requiring aircraft using prescribed altimeter setting procedures to operate at different levels expressed in terms of flight levels it altitudes
The vertical separation minimum (VSM) shall be:
- 1,000ft below FL290 and 2,000ft at or above this level
- 1,000ft below FL410 (RVSM)or a higher level where so prescribed for use under specified conditions and 2,000ft at or above this level
ATC unit shall normally authorise only one level for an aircraft beyond its control area. I.E when coordinated with the next area.
Who is responsible for issuing the clearance?
The accepting ATCU to issue Clearance.
When a/c has been cleared into CTA at a cruising level which is below the established minimum cruising level for a subsequent portion of the route, ATC unit responsible for the area should issue revised clearance to the a/c even though the pilot has not requested the necessary cruising level change.
T
An a/c may be cleared to change cruising level at a specified:
3 things
- time
- place
- rate
In so far as practicable cruising level of a/c flying some to the same destination shall be assigned in a manner that will be correct for an approach sequence at destination.
True
An aircraft at a cruising level shall normally have priority over other a/c requesting that cruising level. True or False?
True
When 2 or more aircraft are the same cruising level, the preceding a/c shall normally have priority. True or False?
True
Eastbound a/c go? And west tracking a/c go?
Odds
Evens
Based on RVSM
Are pressure altimeters Accurate at high level?
No inaccurate due very low pressure
What is the vertical separation in CVSM and RVSM?
What levels are they applicable to?
2,000ft CVSM above FL290
1,000ft RVSM in RVSM airspace FL290-410 and when equipped
Who is responsible for ensuring the A/C is RVSM compliant?
The pilots
If the RVSM fails who must the pilot contact?
Inform ATC
Pilots shall inform ATC if not RVSM when?
1) initial call
2) In all requests for level changes
3) in all read back of level clearance
VFR Flights in Level cruising flight when operated above 3,000ft(unless CAA)
Shall be conducted at a level appropriate to the track
True or False?
True
VFR cruising levels are up to what level?
FL285
Increase VFR by 500ft on IFR levels true or False
True
VFR flight above FL290 is not approved true or False?
True
An a/c may be cleared to a level previously occupied by another a/c after the latter has reported vacated except when:
3 things
1) Severe Turbulence
2) The higher aircraft is effecting a cruise climb
3) the difference in A/C performance is such that less than the applicable separation. Clearances should be with held.
Pilots in direct communication with each other may, with their agreement, be cleared to maintain a specified vertical separation between their aircraft during ascent or descent.
True or False?
True
