: Do not extend the spoilers. or operate with the:
, ~ ~ spoilers deployed. at speeds above VMOjMMO:
: due to significant nose-down pitching moment,
, associated with spoiler deployment. ,
, ,
, 1. Thrust Levers -IDLE. ,
, 2. Autopilot - Disengage. ,
: 3. Identify aircraft pitch and roU attitude. :
, -~ • In any aircraft. attitude (particularly roU atti-:
:~, tude) may be difficult to identify from visual,
, and instrument references in an extreme:
: nose-down condition. ,
: • Do not apply elevator force until bank angle:
, is reduced to less than 90°. A pull elevator'
, force when the bank angle is greater than 90° :
: will increase the nose-down attitude. ,
, 4. Level wings. :
: 5. Elevator and pitch trim - As required to raise the nose. ,
: On any speed excursions beyond MMO. the ele-:
, vator control must be smoothly and steadily ap- :
: plied to prevent encountering excessiva aileron,
, activity and air&ame buffet. Beyond MMO, a'
, 1.5 g pullup may be sufficient to excite aileron:
: activity and the g level must be limited to that re- ,
, quired to maintain lateral control. ,
:If Mach or airspeed is severe or if pitch and/or roU attitude is ex-:
:treme or unknown: :
, 6. Landing Gear Switch - Down. Lowering the landing gear:
: at high speed wiU increase drag and cause a moderate,
, nose-up pitching moment which is easily controllable. but'
: should be anticipated. :
, Extending the landing gear has been flight tested to:
: 0.85 MI and 320 K1AS. Analysis of flight test data indi-,
, cates that this procedure is applicable at higher speeds. ,
:~ Minor damage to the landing gear doors may be :
, 'CAUTION " experienced when the gear is lowered at very'
: high speed. Do not retract landing gear for re- :
, mainder of flight. After landing. a thorough in-:
: spection of the landing gear and doors for,
, condition must be made. ,
