on ground when throttles advanced if aircraft not correct T/O config. WITH aural warning
π CABIN ALTITUDE
cabin altitude ABOVE 10.000 feet, extinguished below. WITH aural warning
STALL warning test
MACH warning test
S - on ground with AC power available
M - prohibited in air
Landing Gear warning cutout switch, when pushed:
Silences LG configuration warning at flaps up - flaps 10 and above 200 feet RA
Selected altitude alert
Current altitude alert
selected: white box around selected altitude, BOLD box around current altitude: between 900β-200β before reaching selected altitude
Current: amber blinking box around current altitude until 200 feet deviation. The flashing continues when: between 900β-200β before reaching selected altitude or selecting a new altitude
BELOW GS light, when pushed:
π§ INOP, illuminated:
Inhibits ground proximity Glideslope alert when below 1000β RA
π§: GPWS computer malfunction OR power is lost: has inputs from ILS, IRS, Stall management computer, ADIRU, EFIC control panel, radio altimeter, FMC
GROUND PROXIMITY SYSTEM TEST
- push
- in flight
On ground:
- lights: below GS, GPWS INOP
- ND: TERR FAIL, TERR TEST, TERRAIN (caution)
- aural sounds: βGlideslope, PULL UP, WINDSHEAR, TERRAIN TERRAIN PULL UP, OBSTACLE OBSTACLE PULL UP, AIRSPEED LOWβ
- alerts: PULL UP + WINDSHEAR
Followed by:
- alerts: radio altimeter based, bank angle, wind shear, look ahead terrain,
- callouts: appraoch
PROHIBITED in flight
Terrain Display
- armed
- aircraft 500β or more above highest terrain in selected range
A - when in: PLN, CTR VOR, CTR APP
- Solid π©: highest elevation terrain
- High-density dotted π©: intermediate elevation terrain
- Low-density dotted π©: lowest elevation terrain
Terrain Display
- when aircraft less than 500β above highest terrain in selected range
- exception
- when does it automatically show
- Solid π: look ahead terrain warning active
- Solid π§: look ahead terrain caution active
- Dotted π: terrain > 2000β above aircraft altitude
- Dotted π§: terrain 500β below- 2000β above aircraft altitude
- Dotted π©: terrain 2000β below - 500β below aircraft altitude
- Dotted πͺ: no terrain data available
- Exception: terrain within 200β of nearest airport RUNWAY elevation does not show
Auto show:
- neither pilot has terrain display selected, and
- Look-ahead terrain alert occurs, and
- EXP MAP, VOR, APP, center MAP
Predictive wind shear
- automatically on ND when
- predictive wind shear alert occurs
- neither pilot has WXR radar display selected
- in EXP MAP, VOR, APP, CTR MAP
TCAS CONTROL
- transponder mode selecter
A - sets TCAS display at UPPER elevation limits
B - sets TCAS display at LOWER elevation limits
TAKEOFF CONFIG WARNING

LANDING GEAR LEVER HORN
- F UP- F10
- F15 - F25
- F30 - F40
WHEN LG NOT DOWN AND LOCKED
F UP - F10
- alt< 800β RA, either thrust lever set between IDLE - 20 DEG thrust lever angle or OIE and operative thrust lever < 34 DEG thrust lever angle
- landing gear warning horn can be silenced until descending below 200β RA
F 15 - F 25

- Landing gear warning horn CAN NOT be silenced
F 30 - F 40
- Regardless of thrust lever position
- Landing gear warning horn CAN NOT be silenced
PSEU monitors:
- pseu light illuminate for single warning:
β when extinguished - pseu light inhibited
T/O + LDG config warnings, landing gear warnings, air/ground sensing
P - ONLY after landing
W β when parking brake is set or both engines turned off
P - in flight, thrust levers advanced for TO power until 30 seconds after landing
Stick shaker
- where and when
One on each control column vibrate and are always armed except on the ground
