305 – CATOBAR – Recovery – CASE III
CASE III Marshal Stack
The holding pattern is a six-minute left-hand pattern. Unless otherwise briefed, the pattern will be flown at max conserve fuel flow or NATOPS holding airspeed. Two-minute turns and one-minute legs are normally used for the pattern. Aircraft must be established at assigned holding altitudes by 10 NM from the Marshall “stack.” Aircraft in the stack will be separated by 1,000 feet vertically.
Strict management of the holding pattern is required to arrive at the fix, at the assigned approach time (push time). For example, arriving in holding at time 16 with a push time of 27, one 6-minute pattern and one 5-minute pattern could be used. But regardless of how the pattern is managed, aircraft must arrive at the holding fix on airspeed (250 kts) and ready to commence the approach at the Expected Approach Time (EAT) plus or minus 10 seconds. If unable to do this, notify Marshal so that timing adjustments to the landing interval can be made.
- Check in BTN 5 (Marshall) call “INBOUND” and fly to the assigned holding
- Commence in your assigned push time(PT) (if SC gives wrong PT keep min 2 min separation between aircrafts)
- Commence call must be made at 21 DME
- Descent to 5000 FT AGL and call “PLATFORM” no later than 18 DME
- At 10 DME mark you should be at 1200 FT AGL and configure for landing
- 8 DME Dirty Up – Gears Down, Flaps as required, Hook Down*, fly on speed
- 6 DME call ACLS lock (Ideally “ON AND ON” )
- 3 DME Call “BULLSEYE” and transit to Fly the Ball (See diagram next slide)
- ¾ NM Call “BALL”
- In case of bolter, fly FB 1 NM and turn back down wind, join landing pattern at 3 NM if no traffic between 3-8 DME – Extend further if necessary
