28
Describe reversal procedures
45/180 = track outbound for published time, then turn away 45deg for 1 min from start of turn, reverse turn through 180 deg and intercept inbound track 80/260 = track outbound for published time. Turn away 80 deg then turn immediately opposite direction to intercept
29

32
An aircraft may commence the approach without entering a hold (assuming no height need to be lost) if:
a. Received ATC clearance b. completed: reversal, DME arc, or within 30deg of the app’s first track c. GNSS: within capture region for an initial app waypoint, or receiving ATC vectors Note: can request a ‘direct to’ intermediate fix (IF) provided the subs track change within 45deg
33

Right 1 min (wind adjusted)
34
When does outbound timing commence during a hold?
Abeam the fix or on attaining the outbound heading, whichever comes later
35
Describe a sector 1 entry
Sector 1 - Parallel entry Over fix, fly 15secs (20s if head wind) then turn to parallel track outbound allowing for drift. Time starts over or abeam fix, whichever’s later Continue until time or DME distance Turn in to intercept inbound track
36
Describe sector 2 entry
Sector 2 - Tear drop Over fix, turn onto the holding side to make good a 30deg offset of the inbound track Fly out IAW time specified, up to 1:30mins or DME limit Turn in to intercept inbound track
37
