Reversal Procedures

Question 1

When is a reversal procedure required?

Answer 1

Where no suitable IAF or IF is available to construct the instrument procedure.
(can be reversal procedure, racetrack, or holding pattern)

Question 2

What does a racetrack procedure consist of?

Answer 2

A turn from the inbound track through 180 degrees frmo overhead the facility or fix on to the outbound track. The outbound leg may be timed or limited by a radial or DME distance; followed by a 180 degree turn in the same direction to return to the inbound track.

Almost similar to a holding pattern.

Question 3

The type of entry into a reversal procedure is based on…

Answer 3

Track (within +/- 30 degrees)

Question 4

How does a racetrack procedure differentiate from a holding pattern?

Answer 4

a) offset entry shall limit the time on the 30 degree offset track to 1 min 30 sec, after which the pilot should turn to a heading parallel to the outbound track for the remainder of the outbound time. If the outbound time is only 1 min, the time on the 30 degree offset track shall be 1 min also.

b) parallel entry shall not return directly to the facility without first intercepting the inbound track

c) all manoeuvring shall be done in so far as possible on the manoeuvring side of the inbound track.

Question 5

What speed restrictions apply in a reversal procedure?

Answer 5

CAT A: 110 kts

Question 6

What bank angle are procedures based on?

Answer 6

The average achieved bank angle of 25 degrees, or the bank angle giving a std. rate turn, whichever is less.

Question 7

When does outbound timing start?

Answer 7

a) From abeam the facility; or
b) on attaining the outbound heading
whichever comes later

Question 8

How is outbound timing corrected for wind?

Answer 8

HWC 1:1 seconds (+ timing)
TWC 0.5:1 seconds (- timing)

Question 9

How to enter a racetrack procedure?

Answer 9

In manner similar to that prescribed for a holding procedure entry with the following considerations:

a) offset entry shall limit the time on the 30 degree offset track to 1 min 30 sec, after which the pilot should turn to a heading parallel to the outbound track for the remainder of the outbound time. If the outbound time is only 1 min, the time on the 30 degree offset track shall be 1 min also.

b) parallel entry shall not return directly to the facility without first intercepting the inbound track

c) all manoeuvring shall be done in so far as possible **on the manoeuvri
