Vertical sep - non RVSM/RVSM

2,000ft above 290
RVSM - 1,000ft below 410/ 2,000 above 410
Essential traffic is defined as
Controlled traffic that is not/ or will not be separated by the req minimum
When can a/c be assigned a level
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
Clearance to maintain own separation in Vmc in the climb and descent is allowed if
Requested by the pilot Class D and E airspace Vmc Day Below 10,000
Lateral separation
VOR - track divergence 15*
NDB - 30*
DR - 45*
At 15nm
Same track sep
Track of 2 a/c converge/diverge by less than 45* or more than 315*
Reciprocal track sep
More than 135* but less than 225*
Crossing track sep
Tracks which intersect at angles of 45* to 135* or 225* to 315*
Long sep, time based same track
Standard - 15min
Can be reduced to
10min with navaids
5min lead a/c 20kts faster
3min lead a/c 40kts faster
Long sep, time based crossing track
Standard = 15min
Reduced to 10min with navaids
Long sep, time based climbing/descending same track
Standard = 15min
10min with nav aids - if lead a/c starts to climb/descend within 10mins of passing navaid - further reduced to 5mins
Long sep, time based reciprocal track
20 mins
10 after the a/c pass each other
Long sep, nm same track
Standard = 20nm
10 - 20kts or faster
Long sep, nm crossing track
Standard = 20nm
10 - 20kts or faster
Long sep, nm climbing/descending
Standard = 10nm
Long sep, nm reciprocal
10nm apart having passed
Long sep, nm same mach no

RNAV sep
150km/80nm
RNP10 = 50nm
Radar sep nm
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
Light category
7,000kg or less
Medium category
Greater than 7000kg to 136000kg
Wake turb aprchs sep mins
M behind H = 2min
L behind M or H = 3min
Wake turb dep sep mins
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
Radar wake turb nm sep
H behind H = 4nm
M behind H = 5nm
L behind H = 6nm
L behind M = 5nm
When are you cleared for t/o on a VMC dep
Preceding a/c has passed the upwind r/y or made a turn away from the r/y
IFR dep sep mins
Standard = 5
Lead a/c 40kts + = 2
Track diverges >45* = 1
Dep/arriving a/c 45* r/y alignment is permitted till
5mins for a straight in app
Start of the procedure turn
Outside 45* alignment - 3mins before ETA/designated fix
EAT
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 +
When will you get a revised EAT
Differs more than 5mins or more from the original EAT
