二 測試程序
Flight test procedure
A.作動駕駛盤至中立位，將 P5板上的擾流板電門A和B置于OFF位；
Center the control wheel and position spoiler switches A and B on P5 panel to OFF;
B. 將P5板上的FLT CONTROL電門B置ON位，F(xiàn)LT CONTROL電門A置OFF 位（注意：在其轉(zhuǎn)換過程中，飛機(jī)可能上下俯仰），謹(jǐn)慎操作升降舵、 副翼、感覺操縱力是否改變，并記錄：
Position flight control switch B to ON and flight control switch A to OFF in that order (NOTE: Airplane may pitch up or pitch down during the transition), Carefully move elevators, ailerons and rudder, write down the control forces and responses.
a.各感覺操縱力未改變（此表明系統(tǒng)工作正常）；
The control forces and responses do not change (This means system is OK)
b.升降舵操縱力改變;
The elevator control force changed.
c.副翼操縱力改變;
The aileron control force changed.

d.方向舵操縱力改變;
The rudder control force changed.
C. 將P5板上的FLT CONTROL電門A置ON位，F(xiàn)LT CONTROL電門B置OFF 位（注意：在其轉(zhuǎn)換過程中，飛機(jī)可能上下俯仰），謹(jǐn)慎操作升降舵、 副翼、感覺操縱力是否改變，并記錄：
Position flight control switch B to ON and flight control switch A to OFF in that order (NOTE: Airplane may pitch up or pitch down during the transition), Carefully move elevators, ailerons and rudder, write down the control forces and responses.

D.將P5板上的FLT CONTROL電門B置STBY RUD位，F(xiàn)LT CONTROL電門A置 OFF位（注意：在其轉(zhuǎn)換過程中，飛機(jī)可能上下俯仰）；
Position flight control switch B to STBY RUD and flight control switch A to OFF
in that order (NOTE: Airplane may pitch up or pitch down during the transition).
a.使用安定面配平來保持飛機(jī)俯仰水平，其安定面配平輪不應(yīng)超過3圈，如超過，記錄其實際值 ；
Check that airplane pitch up or pitch down does not exceed 3 turns of stabilizer. If the value exceeded, make note.
b.使用方向舵配平來保持飛機(jī)機(jī)翼水平;
Trim the airplane using the rudder to keep heading with the wing level.
(1).此時方向舵配平不應(yīng)超過 1-1/2個單位，如超過，記錄其實際值：；
Make sure that rudder trim does not change more than 1-1/2 unit, If the value exceeded, make note.
c.如果飛機(jī)有滾轉(zhuǎn)趨勢，請記錄：
Monitor any roll tendency, make note.
(1). 左滾轉(zhuǎn)
(2).右滾轉(zhuǎn)
Left roll Right roll
d.將駕駛盤左轉(zhuǎn)30度，再將駕駛盤右轉(zhuǎn)30度，感覺操縱力差別不大， 如差值大，記錄：

Turn control wheel 30 degrees right and 30 degrees left, make sure wheel forces are symmetrical. If asymmetrical much, make note:
(1).
左轉(zhuǎn)操縱力大； (2). 右轉(zhuǎn)操縱力大；
Left wheel force big; Right wheel force big
E.將P5板上的FLT CONTROL電門A置STBY RUD位，F(xiàn)LT CONTROL電門B置 OFF位（注意：在其轉(zhuǎn)換過程中，飛機(jī)可能上下俯仰）;
Position flight control switch A to STBY RUD and flight control switch B to OFF in that order (NOTE: Airplane may pitch up or pitch down during the transition).
