Chapter 14 Separation Flashcards
What are the three components of separation?
Vertical, horizontal and composite
What is essential traffic?
Controlled traffic to which atc separation is applicable but to which in relation to another controlled flight, is not or will not be separated by the required minimum
What is the non RVSM separation?
At and Below 290 = 1000ft
Above 290 = 2000ft
What is the RVSM separation?
410 and below = 1000ft
Above 410 = 2000ft
During severe turbulence what is done in terms of allocation of FLs?
Will be witheld until aircraft has been separated by the required minimum
When is it allowed to maintain your own traffic clearance?
- requested by pilot
- approved by 2nd pilot
- class d and e airspace only *****
- vmc
- day
- below 10000ft
- alternative instructions given
What are the two sections of horizontal separation?
Lateral and longitudinal
What is lateral separation required on a VOR?
Track divergence of 15 degrees at 15nm
What is lateral separation required on a NDB?
Track divergence of 30 degrees at 15nm
What is lateral separation required on a GNSS?
15nm below FL190 and 23nm above FL200
What does standard separation mean?
Minimum
What is the standard longitudinal separation on the same track?
15mins
- Can be reduced to 10mins when sufficient Navaids)
- can be reduced to 5 mins if ac ahead is 20kts faster
- can be reduced to 3 mins if ac ahead is 40kts faster
What is the standard crossing track separation?
15 mins = standard
10 mins = with sufficient navaids
What is the standard climb/descent separation?
15mins
- Can be reduced to 10mins with sufficient navaids
- can be reduced to 5 mins near reporting point
What is the climb/descent separation on reciprocal tracks?
20mins after they have passed each other
What is the longitudinal separation based on DME?
Same track = 20nm (standard)
Can be reduced to 10nm if 20kts faster
(Same for crossing tracks)
What is the longitudinal separation DME when climbing or descending?
10nm
Separation for reciprocal tracks the same
What is the standard longitudinal separation based on Mach number?
Same Mach number = 10mins
Minus 1 min for each 0.01 of a Mach number up to 0.06 difference
What is the rnav separation?
150km/80nm
Unless RNP10 where separation = 50nm
What is the standard radar separation distance?
5nm
Can be reduced to 3nm if radar allows
What is the heavy category?
MTOM equal to or greater than 136000kg
What is the medium category?
MTOM between 7000kg and 136000kg
What is the light category?w
MTOM less than or equal to 7000kg
What is the wake turbulence separation on approaches?
Medium behind a heavy = 2 mins
Light behind a medium or heavy = 3 mins
What is the wake turbulence separation on departure?
Light or medium behind a heavy or light behind a medium = 2 mins
When:
- using same rwy
- parallel rwy less than 760m away from each other
- when vertical separation is less than 1000ft
When can departure wake turbulence separation be changed to 3 mins?
When using an intersection on the same rwy or on parallel rwys
What is the wake turbulence separation on a displaced threshold of departure?
2 mins
What is opposite direction wake turbulence separation?
2 mins
What is the radar wake turbulence separation?
H behind a H = 4nm
M behind a H = 5nm
L behind a H = 6nm
L behind a M = 5nm
What is essential local traffic?
Any vehicle or personnel which may constitute a collision hazard to a departing or arriving aircraft
When are aircraft allowed to takeoff in VMC?
Once the preceding ac has passed the upwind leg or has made a turn away from the rwy
What is the standard separtion between departing IFR traffic?
5 mins
- can be reduced to 2 mins if 40kts faster
- can reduced to 1 min if ac ahead diverges by 45 degrees
When can an ac takeoff in the opposite direction to arriving ac?
- up until the arriving ac has done its procedure turn
- up until the arriving ac is 5nm from threshold
Who is given priority given to in the hold?
- ac with emergencies
- any hospital aircraft that have indicated in their flight plan
- any ac engaged in SAR
- ac as determined by the authority
When is an EAT given?
If ac are subjected to a delay of 10mins or more
To what aircraft must EAT be sent ASAP?
Ac expected to hold for more than 30mins
When no delay expected is said what delay is expected?
Max 20 mins
How will EAT be revised?
By 5 min intervals
What is separation maintained over mountainous regions?
- visual observations
- use of navaids
- rnav equipment
