Flight Operations Flashcards
What is the OCH
Obstacle clearance height above runway level, taking into account height lost whilst conducting a go around
Minimum height rule
No less than 1000ft above highest obstacle within 5nm
What coloured lights for obstacles
> 150m = high intensity flashing white day and night
<150 but > 300ft = medium intensity steady red by night
Instrument approach chart MSA
1000ft within 25nm of the homing facility
Cruising levels
0-179 = odd thousands
180-359= even thousands
Why do flight level separations increase to 2000ft above FL290 in non RVSM
Due to altimeter errors as the air is less dense
Requirement for the lowest useable en route flight level
500ft above absolute minimum altitude
When are mid point and stop end rvr values reported
-When they are less than the touchdown zone and <800m
-when they are less than 400m
Standard circuit direction
Left
Rate 1, 2, 3 turns
Rate 1 = 3degs per sec
Rate 2 = 6 degs per sec
Rate 3 = 9 degs per sec
Wind direction and speed when descending
Backs and slows
ICAO weight categories
Heavy = more /equal to 136,000kg
Medium = >7000kg, <136,000kg
Light = 7000kg or less
Separation times final approach
Medium behind heavy = 2 min
Light behind heavy = 3min
Light behind medium = 3min
When can you descend on an NDB procedure
-when are the descent point defined on the procedure
-within 5degrees of the ADF
When can you descend on the glide path
When cleared for the procedure
Captured the localiser within 5 degs
ROD calculation for glideslope 3 deg
5 x ground speed
Minimum rvr for take off
150m (some places 125m) when high intensity lights used
