Q

What is the standard longitudinal separation on the same track?

A

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

16
Q

What is the longitudinal separation based on DME?

A

Same track = 20nm (standard)

Can be reduced to 10nm if 20kts faster

(Same for crossing tracks)

17
Q

What is the longitudinal separation DME when climbing or descending?

A

10nm

Separation for reciprocal tracks the same

18
Q

What is the standard longitudinal separation based on Mach number?

A

Same Mach number = 10mins

Minus 1 min for each 0.01 of a Mach number up to 0.06 difference

19
Q

What is the rnav separation?

A

150km/80nm

Unless RNP10 where separation = 50nm

20
Q

What is the standard radar separation distance?

A

5nm

Can be reduced to 3nm if radar allows

21
Q

What is the heavy category?

A

MTOM equal to or greater than 136000kg

22
Q

What is the medium category?

A

MTOM between 7000kg and 136000kg

23
Q

What is the light category?w

A

MTOM less than or equal to 7000kg

24
Q

What is the wake turbulence separation on approaches?

A

Medium behind a heavy = 2 mins

Light behind a medium or heavy = 3 mins

25
Q

What is the wake turbulence separation on departure?

A

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

26
Q

When can departure wake turbulence separation be changed to 3 mins?

A

When using an intersection on the same rwy or on parallel rwys

27
Q

What is the wake turbulence separation on a displaced threshold of departure?

A

2 mins

28
Q

What is opposite direction wake turbulence separation?

A

2 mins

29
Q

What is the radar wake turbulence separation?

A

H behind a H = 4nm
M behind a H = 5nm
L behind a H = 6nm
L behind a M = 5nm

30
Q

What is essential local traffic?

A

Any vehicle or personnel which may constitute a collision hazard to a departing or arriving aircraft

31
Q

When are aircraft allowed to takeoff in VMC?

A

Once the preceding ac has passed the upwind leg or has made a turn away from the rwy

32
Q

What is the standard separtion between departing IFR traffic?

A

5 mins

  • can be reduced to 2 mins if 40kts faster
  • can reduced to 1 min if ac ahead diverges by 45 degrees
33
Q

When can an ac takeoff in the opposite direction to arriving ac?

A
  • up until the arriving ac has done its procedure turn

- up until the arriving ac is 5nm from threshold

34
Q

Who is given priority given to in the hold?

A
  • ac with emergencies
  • any hospital aircraft that have indicated in their flight plan
  • any ac engaged in SAR
  • ac as determined by the authority
35
Q

When is an EAT given?

A

If ac are subjected to a delay of 10mins or more

36
Q

To what aircraft must EAT be sent ASAP?

A

Ac expected to hold for more than 30mins

37
Q

When no delay expected is said what delay is expected?

A

Max 20 mins

38
Q

How will EAT be revised?

A

By 5 min intervals

39
Q

What is separation maintained over mountainous regions?

A
  • visual observations
  • use of navaids
  • rnav equipment
