- Don oxy masks………….. Set 100%
- Crew comm……………….. Establish
- Press mode selector………..MAN
- Outflow valve sw….. Hold in CLOSE until the outflow valve indication shows fully closed
- If cabin alt is uncontrollable:
Pax sign ………………..ON
Pax oxy switch ……….ON
Go to emergency descent CL
Elevator Tab Limit Cycle Oscillation
Airspeed ……….Reduce to 270kts/until vibration ceases (whichever is lower)
Do not use Speedbrakes …..Do not change a/c config to slow a/c
