IR Phase Flashcards
Specific radial to and from
QDR QDMpp
Accuracy required for tracking a radial
+ - 5 deg
Half scale when using CDI
Correcting heading error message to beacon
Apply double the heading error and anti pare capturing the heading
Flying away from beacon
Needle pointing right of heading
Fly left
Again fly double the track error to intercept
Needle to and from the beacon? Correction s
To the beacon follow the needle
From the beacon follow the tail of the beacon
Using the same beacon and intercepting a new radial at different distance
Visualise the aircraft on the compass rose and use the outer circles as distances. Transfer these on the centre of the compass rose and you can figure out the distance and radial
What categorie approach do we use?
Pans Ops
Cat A
Reversal procedure
Reversal is required if the hold is in the same plane as the outbound track. Therefore as you fly over the beacon you make a tear drop to turn onto ourbound.
If arriving within 30 deg of outbound you can join straight on
If 30 of reversal heading could joking straight into tear drop
Race track procedure
Pretty much flying the hold outbound using corrected drift (x3) then when abeam beacon flying outbound on single drift.
DME arcing
Using set distance from DME to fly on arc until a certain radial
Outbound timing corrections
One second per knot of head or tail wind per minute
Procedure 3min outbound
20kts tailwind
20x3 = 60
Outbound is 2 mins
Turns in a hold
25 deg or rate 1 which ever is least
Gate angle form beacon
30 degrees
Sops for parellel join
Correct timing at 1.5 times the headwind
Limit relative bearing to 20-25 degrees
Roll out of outbound turn when needle passes through the nose
Intercept 20 relative bearing
When it hits 25 degrees turn towards 20degreews to restore
Keep repeating until with 10degree
Then turn onto inbound heading with drift applied
Using NDB with parrell entry SOPs
NDB is prone to dip when aircraft is turning so roll out when needle is less so around 5-10 degrees through the nose
