LANDING WITH A FLAT MAIN TIRE
1. Approach
NORMAL
2. Wing Flaps
SET TO LANDING POSITION
3. Touchdown
Touch down on the inflated tire first and maintain full aileron deflection
towards the good tire, keeping the flat tire off the ground for as long as possible. Be
prepared for abnormal yaw in the direction of the flat tire.
LANDING WITH A FLAT NOSE TIRE
1. Approach
NORMAL
2. Wing Flaps
SET TO LANDING POSITION
3. Touchdown
Touch down on the main landing gear tires first. Maintain sufficient back
elevator deflection to keep the nose tire off the ground for as long as possible.
SPEEDBRAKE
TM
SYSTEM MALFUNCTION
1. SpeedBrake
TM
Switch
SET TO OFF/DOWN POSITION
2. SpeedBrake
TM
Circuit Breaker
PULL
NOTE
If the SpeedBrake™ System should malfunction or perform improperly, do
not attempt to identify or analyze the problem. If the malfunction results in
an abnormal change in the pitch and/or roll axis, immediately regain control
of the airplane by the input of control forces that override the SpeedBrake™
failure(s). Do not, under any circumstances, re-engage a SpeedBrake™
System that has malfunctioned until the problem is corrected.
ELECTRICAL SYSTEM OVERCHARGING*
(Both alternators stay on-line, ammeter shows
excessive charge, and voltmeter has high voltage indication.)
1. Defective Alternator Switch
SET TO OFF
2. Crosstie Switch
SET TO ON
3. Flight
If electrical system is restored, continue with flight. If electrical system is not
restored, land as soon as practicable.
*
NOTE
The voltage regulator will trip the alternator off-line in conditions of over
voltage, i.e., greater than 16.0 volts. If this happens the annunciator panel
will indicate the alternator is out. The most likely cause is transitory spikes
or surges tripped the alternator off-line.
ALTERNATOR FAILURE—ELECTRICAL SYSTEM DISCHARGING
(Ammeter shows a
discharging condition on the left or right bus, and the alternator annunciator indicates “L Alt
Off” or “R Alt Off”)
1. Crosstie Switch
SET TO OFF
2. Affected Alternator Master Switch
CYCLE OFF THEN ON
3. Alternator Annunciator Lights (Follow either step 3.1 or 3.2 below)
3.1. Alternators Annunciator Light Off
If after recycling the system, the alternator
annunciator light stays off, proceed with normal operations.
