autopilot does what with stall warniing
disengages
steering pin positions
horizontal for towing / on the ground

nose wheel steering
Manually controlled, hydraulically actuated system provides 45 degrees right and left of center deflection
if loss of hydraulic power, can we (ground) steer the hawker
no
nose wheel steering not available when main pressure less than 2300 psi
illumination of red annunciators mean what
gear in transit, gear unlocked, or gear down and locked with gear selector lever out of down position
if gear is up and locked lights
all out
if gear is unlocked
red lights
gear is down and locked
green lights
gear down and locked, handle in wrong position
all lights (green and red)
what is the max gear extended speed
220kts
calls for gear
three green (gear speed 220)
pin (main counsel by thrust levers, should be out for nose wheel)
pressure (don’t want brakes applied)
center (tiller should be centered)
back up (lights on right side)
what’s a way to tell if gear is down if all gear systems are being wonky so
try flaps 25 - if horn goes off, gear is not down
gear horns
Gear not down and flaps 25, 45
Gear not down when aircraft is on ground and starter bus on
Gear not down and thrust angle below 60-70% and airspeed below 150 kts
which gear horn warning can be overridden
Gear not down and thrust angle below 60-70% and airspeed below 150 kts
how is normal vs emergency vs parking brake selected
WHEEL BRAKe lever on center pedestal
when is anti skid protection provided
during normal brake operations only
what is the anti skid system called
maxaret
when will you know if you need emergency brakes
if you land and the brakes don’t work!
or hydraulic system failure
how does maxaret work
mechanical
wheel must be moving
for lift dump to work
on ground
“selected” 45 flaps
airbrake limitations
NO FLAPS
what is/is not included in the landing distance in the POM
thrust reverser not included
lift dump included
on landing what do we use first and second
lift dump first
thust reverse 2nd
what are takeoff flaps
0, 15
landing flaps
25, 45
where are indicated flaps
FO mfd
ELEV/AIL TRIM
elevator OR aileron trim has failed
full flaps speed
165
25 flap speed
175
15 flap speed
220
stall warning
stick shaker
disengages autopilot
stall happening
stick pusher
what does one and two channels do for stalls
one channel activates stick shaker
both channels must agree for stick pusher
What is powered by the PE bus bar
normal landing gear annunciators
warning horn control
warning horn
L and R EMERG WHEEL BRAKE annunciators
What does the PS1 bus bar power
landing gear lever lock solenoid
normal BRAKES applied pressure indicator
What does the PS2 bus bar power
standby landing gear downlink annunciator (2)
Inadvertent landing gear retraction on the ground is prevented by
a solenoid-operated device engaging the selector lever
when all landing gear are up and locked, the position indications are
no green or red annunciators are illuminated
the main landing gear inboard doors are closed
when the gear is in either the extended or the retracted position
the landing gear warning horn will sound when
gear is not locked down with flaps selected 25
the gear is not locked down with either power lever between 60% and 70% N1 and airspeed below 150kts
the gear is down and locked, the LANDING GEAR lever is not selected down, and start power is selected
an indication of landing gear down and locked accompanied by 3 red annunciators indicates
the LANDING GEAR lever is not in the down position and the landing gear is down and locked
if the nose gear does not lock down during extension, the indication is that
the red N GEAR annunciator on the panel is illuminated and the mechanical indicator on the pedestal is not extended
nose wheel steering with the gear retracted is prevented by
A mechanically actuated hydraulic shutoff valve
the EMRG BRK LO PRESS annunciator illuminates
when emergency brake accumulator pressure drops to 2250 psi and below
in order to select emergency brakes, the WHEEL BRAKE lever must be positioned
to first aft notch marked in red
stall warning system uses ____ power
DC and AC
Elevator trim tabs can be actuated
mechanically and electrically
The purpose of the rudder bias system is
to automatically counteract asymmetrical thrust due to engine failure
if takeoff is attempted with the aileron/elevator gust lock
only one throttle can be advanced to full power
the guard is removed from a pitch trim switch
during testing, to ascertain that trimming cannot be accomplished with one element of the switch
the flight control surfaces that are hydraulically actuated are
flaps and airbrakes
asymmetrical flap operation is prevented by
a synchronizing cable arrangement that isolates the hydraulic supply to the flap motor, stopping the flaps
the purpose of lift dump is
to increase drag and decrease lift on the ground
stall warning is provided by
the stick shaker
stall identification is provided by
the stick pusher
in the stall warning and identification system
flap position is integrated with angle-of-attack signals to determine critical angle of attack of the wing
inadvertent stick pusher operation can be prevented by inhibiting
Both channel 1 and channel 2 at the same time
the rudder bias annunciator extinguishes when
Both RUDDER BIAS switches are on
Emergency brake system annunciators
white L/F EMERG WHEEL BRAKE when 1000 psi or more applied to brakes with WHEEL BRAKE lever in EMERG or PARK BRAKE position
