High vibration indicates a malfunction that may worsen and increase vibration severity. Therefore, a continuous engine operation with vibration in amber range is not recommended. According to engine vibration limits, the pilot may not elect to reduce TLA for vibration below vibration 2.5 IPS time limited to 5 mins during t/o or go-around or 10 seconds during remainder flight phases. If vibration returns to the green range within 5 mins, the flight may continue but vibration causes should be investigated before the next flight. Vibration in any phase of flight in the amber range up to 1.5 IPS for less than 30 seconds does not require mx action.)

Airplane must not be moved during power-up initialization. Do not cage attitude in turning flight.
Electromechanical Gust Lock
Each time electromechanical gust lock lever is set to unlocked position elevator movement must be checked. This check must be performed at least 10 seconds after positioning the gust lock lever to the unlocked position by moving the control column from the full up stop to the full down stop and back to the full up stop position.

On airplanes equipped with a cockpit security door, two crew members must be in the cockpit during all flight phases. If one of pilots leaves flight deck, he must be replaced in cockpit by another crew member. Positive identification of the person wishing to enter the flight deck must be obtained before opening the door. Security cockpit door must be kept closed and locked at all times during flight except to permit access and egress according to GOM procedures 6-1.2.1 for opening, closing and locking the door. Anytime that cockpit door is opened in flight, a challenge and response closing and locking verification procedure must be used to verify that door is closed and locked.

Engine Warm-up
Prior to take-off, the engines must be allowed to run at low thrust to stabilize the engine temperatures before take-off thrust is adjusted. After start, the engines must run at idle or taxi thrust during at least 4 minutes for cold engines (shut down for more than 90 minutes) or 2 minutes for warm engines. To increase N2 above 83% the engine oil temperature must be at 40o C minimum. In lieu of this limit, it is acceptable to either run the engine for at least 8 minutes or complete a static run- up to 88% N2, stabilize, and check to ensure that oil pressure is equal to or less than 83 psi.
Engine Cool-Down
The engines must run for at least 1 minute at idle or taxi thrust before shut-down.
