illumination of red annunciators mean what

gear in transit, gear unlocked, or gear down and locked with gear selector lever out of down position

How well did you know this?

Perfectly

if gear is up and locked lights

all out

How well did you know this?

Not at all

Perfectly

if gear is unlocked

red lights

How well did you know this?

Not at all

Perfectly

gear is down and locked

green lights

How well did you know this?

Not at all

Perfectly

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
