2,000ft above 290

RVSM - 1,000ft below 410/ 2,000 above 410

Question 3

Essential traffic is defined as

Answer 3

Controlled traffic that is not/ or will not be separated by the req minimum

Question 4

When can a/c be assigned a level

Answer 4

Normal conditions - as soon as the a/c has reports vacating the level

Severe turbulence - once a/c reports at level separated by the req minimum

Question 5

Clearance to maintain own separation in Vmc in the climb and descent is allowed if

Answer 5

Requested by the pilot 
Class D and E airspace 
Vmc 
Day 
Below 10,000

Question 6

Lateral separation

Answer 6

VOR - track divergence 15*
NDB - 30*
DR - 45*

At 15nm

Question 7

Same track sep

Answer 7

Track of 2 a/c converge/diverge by less than 45* or more than 315*

Question 8

Reciprocal track sep

Answer 8

More than 135* but less than 225*

Question 9

Crossing track sep

Answer 9

Tracks which intersect at angles of 45* to 135* or 225* to 315*

Question 10

Long sep, time based same track

Answer 10

Standard - 15min

Can be reduced to
10min with navaids
5min lead a/c 20kts faster
3min lead a/c 40kts faster

Question 11

Long sep, time based crossing track

Answer 11

Standard = 15min

Reduced to 10min with navaids

Question 12

Long sep, time based climbing/descending same track

Answer 12

Standard = 15min

10min with nav aids - if lead a/c starts to climb/descend within 10mins of passing navaid - further reduced to 5mins

Question 13

Long sep, time based reciprocal track

Answer 13

20 mins

10 after the a/c pass each other

Question 14

Long sep, nm same track

Answer 14

Standard = 20nm

10 - 20kts or faster

Question 15

Long sep, nm crossing track

Answer 15

Standard = 20nm

10 - 20kts or faster

Question 16

Long sep, nm climbing/descending

Answer 16

Standard = 10nm

Question 17

Long sep, nm reciprocal

Answer 17

10nm apart having passed

Question 18

Long sep, nm same mach no

Answer 18

10nm

Question 19

Long sep, nm mach no

Answer 19

Diff in mach no

0. 01 = 10mins
1. 02 = 9 mins
2. 03 = 8
3. 04 = 7
4. 05 = 6
5. 06 = 5

Question 20

RNAV sep

Answer 20

150km/80nm

RNP10 = 50nm

Question 21

Radar sep nm

Answer 21

Standard = 5

3 when radar permits

2.5 - both on the same loc and within 10nm of threshold

Mode 2 parallel on adjacent loc = 2

Question 22

Light category

Answer 22

7,000kg or less

Question 23

Medium category

Answer 23

Greater than 7000kg to 136000kg

Question 24

Wake turb aprchs sep mins

Answer 24

M behind H = 2min

L behind M or H = 3min

Question 25

Wake turb dep sep mins

Answer 25

Using the same r/y or parallel r/y separated <760m vertical sep 1,000ft - L behind M = 2 - L or M behind H = 2

Intermediate part of the r/y or parallel r/y = 3

Displaced threshold/ opposite direction = 2

Question 26

Radar wake turb nm sep

Answer 26

H behind H = 4nm

M behind H = 5nm

L behind H = 6nm

L behind M = 5nm

Question 27

When are you cleared for t/o on a VMC dep

Answer 27

Preceding a/c has passed the upwind r/y or made a turn away from the r/y

Question 28

IFR dep sep mins

Answer 28

Standard = 5

Lead a/c 40kts + = 2

Track diverges >45* = 1

Question 29

Dep/arriving a/c 45* r/y alignment is permitted till

Answer 29

5mins for a straight in app

Start of the procedure turn

Outside 45* alignment - 3mins before ETA/designated fix

Question 30

EAT

Answer 30

Expected app time - time when the pilot is expected to leave the hold

Passed to a/c subjected to a delay of 10mins or more - mist be sent expeditiously to a//c when the delayed for 30mins +

Question 31

When will you get a revised EAT

Answer 31

Differs more than 5mins or more from the original EAT
