Q

Severe Turbulence

A

Vol 1 sup procedure SP 16.25

During flight in light to moderate turbulence, the autopilot and/or autothrottle may remain engaged unless performance is objectionable. Increased thrust lever activity can be expected when encountering wind, temperature changes and large pressure changes. Short–time airspeed excursions of 10 to 15 knots can be expected.

Passenger signs ………………………………………………………………………..ON Advise passengers to fasten seat belts prior to entering areas of reported or anticipated turbulence. Instruct the cabin crew to check that all passengers’ seat belts are fastened.

Severe Turbulence

Yaw Damper ……………………………………………………………………………ON

Autothrottle……………………………………………………………………Disengage

AUTOPILOT ……………………………………………………………………….. CWS A/P status annunciators display CWS for pitch and roll.

Note: If sustained trimming occurs, disengage the autopilot.

ENGINE START switches ……………………………………………………….FLT

Thrust ………………………………………………………………………………………Set Set thrust as needed for the phase of flight. Change thrust setting only if needed to modify an unacceptable speed trend.

CLIMB 280 knots or .76 Mach whichever is lower.

CRUISE Use FMC recommended thrust settings. If the FMC is inoperative, refer to the Unreliable Airspeed page in the Performance–Inflight section of the QRH for approximate N1 settings that maintain near optimum penetration airspeed.

DESCENT .76 Mach/280/250 knots whichever is lower. If severe turbulence is encountered at altitudes below 15,000 feet and the airplane gross weight is less than the maximum landing weight, the airplane may be slowed to 250 knots in the clean configuration.

Note : if an approach must be made in an area of severe turbulence, delay flap extension as long as possible. The airplane can withstand higher gust loads in the clean configuration.
