Additional procedures for securing the airplane during sandy or dusty
conditions may be needed. These procedures are normally done by
maintenance personnel, and include, but are not limited to:
• engine covers installed, if applicable.
• protective covers and plugs installed (streamers should be used to
remind personnel to remove before flight).
• doors and sliding windows closed.
• all compartments closed.
Turbulence
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.
