Q

SMYD computers determine when stall warning is required upon:
- sends signals to

A
  • Alpha Vane AoA outputs
  • ADIRU outputs
  • air/ground sensing
  • FMC outputs
  • anti-ice controls
  • wing configurations
  • thrust

S - PLI

17
Q

Altitude alerting
- inhibited

A

I - when trailing edge flaps are extended to F25 or greater OR when G/S is captured

18
Q

GPWS
- provides alerts based on
- alerts are for:
- Windshear warning priority over

A

P - Radio altitude and combination of: altitude, airspeed, glide slope deviation, and airplane configuration

Alerts are for:
- excessive descent rate
- excessive terrain closure rate
- altitude loss after Takeoff or Go-around
- unsafe terrain clearance when not in landing configuration
- excessive deviation below the ILS or GLS glide slope or the FMC generated flight path angle
- excessive deviation below glide path

W - over look-ahead terrain alert and radio altitude based alerts

19
Q

Look-ahead terrain alerting
- based on:

A

Based: on airplane’s position, barometric altitude, vertical flight path, and ground speed

20
Q

Look-ahead terrain alerting
- TERRAIN TERRAIN, PULL UP
- CAUTION TERRAIN
- TOO LOW, TERRAIN

A

T - 20-30 seconds from impact with terrain shown 🟥 on NAV display: PULL UP on both attitude indicators
C - 40-60 seconds from impact with terrain shown 🟧 on NAV display
T - Descent below unsafe radio altitude: PULL UP on both attitude indicators

21
Q

Radio altitude based alerts
- PULL UP
- TERRAIN
- DON’T SINK
- GLIDESLOPE
- SINK RATE
- TOO LOW, FLAPS
- TOO LOW, GEAR
- TOO LOW, TERRAIN

A

ON ALL PULL UP ON BOTH ATTITUDE INDICATORS

PULL - follows SINK RATE alert if excessive descent rate continues, follows radio altitude based TERRAIN alert if excessive terrain closure continues
TERRAIN - Excessive terrain closure
DON’T SINK - Excessive altitude loss after takeoff or go-around
GLIDESLOPE - deviation below GS or GP, ground proximity light cancels or inhibits below 1000’RA when pushed
SINK RATE - excessive descent rate
TOO LOW, FLAPS - unsafe terrain clearance at low airspeed with flaps not in normal landing position. Push flap inhibit, inhibits the alert
TOO LOW, GEAR - unsafe terrain clearance at low airspeed with LG not down. Push gear inhibit inhibits the alert
TOO LOW, TERRAIN - unsafe terrain clearance at high airspeed with either LG not down or flaps not in LDG position. Follows DON’T SINK if another descent is initiated after initial alert

22
Q

Obstacle alerts
- OBSTACLE OBSTACLE, PULL UP
- CAUTION OBSTACLE

A

O - PULL UP on both attitude indicators, 20 - 30 sec from impact 🟥 on ND
C - 40 - 60 sec from project impact 🟧 on ND

23
Q

Windshear alert
- detected by
- enabled when
- when does detection begin
- when does WX radar begins scanning:

A

D - GPWS
E - below 1500’ RA
W - windshear detection begins at rotation
When
- thrust levers set for takeoff, even if engine is off or IRS not aligned, or
- in flight below 2300’ RA (predictive wind shear alert issued below 1200’ RA)

24
Q

Windshear
- WINDSHEAR AHEAD
- GO AROUND, WINDSHEAR AHEAD
- MONITOR RADAR DISPLAY

A

Predictive wind shear symbol on ND display shows its position on all 3 types.

  • WINDSHEAR: 🟥 Symbol on both attitude indicators, 🟥 wind shear symbol + message on NAV display. wind shear close and ahead of airplane. Enabled during takeoff below 1200’ RA
  • GO AROUND, WINDSHEAR: 🟥 Symbol on both attitude indicators, 🟥 wind shear symbol + message on NAV display. wind shear within 1.5 miles and directly ahead of airplane. Enabled during approach below 1200’ RA
  • MONITOR RADAR DISPLAY: 🟥 Symbol on both attitude indicators, 🟥 wind shear symbol + message on NAV display. wind shear symbol on ND, 🟧 wind shear message on ND. wind shear within 3 miles and ahead of airplane, enable during takeoff and approach below 1200’
25
Q

Windshear
- when alert available
- predictive wind shear alert area:
- when new predictive wind shear caution alerts are inhibited

A

W - approximately 12 seconds after WX radar begins scanning for wind shear. predictive wind shear alerts can be enabled prior to TO by pushing EFIS control panel WXR switch

predictive wind shear alert area
- On GND: .5 nm(side) - 3nm(ahead), 30 DEG L and 30 DEG right
- in FLT: .5nm (side) - 1.5nm(ahead), 30 DEG L and 30 DEG R up to 3NM

When: during takeoff and landing are inhibited between 80 KTS and 400 feet RA. A new warning alert between 100 KTS and 50 feet RA. these inhibits do not remove existing predictive wind shear alerts.

26
Q

Bank angle alert
- what alert and when provided, and what inputs

A

W - provided by GPWS when there is excessive roll of airplane. Silent until system is reset at 30 DEG bank. Inputs from radio altitude and bank angle
- from 3 - 30 feet AGL: alert sounds when the bank angle exceeds 10 DEG
- from 30 - 130 feet AGL: alert sounds linearly from bank angle 10 DEG at 30 feet AGL - bank angle 35 DEG at 130 feet AGL
- above 130 feet AGL, alert sounds when the bank angle exceeds 35, 40 or 45 degrees

27
Q

IAN Autopilot alert
- when

A

Autopilot engaged below 100 feet RA with either FAC or G/P engaged

28
Q

TCAS
- TA , RA
- proximate traffic
- TCAS auto show on ND

A

TA 40 sec, RA 25 sec
Prox - within 6 miles and 1200 feet vertically but NOT expected to cause TA/RA
AUTO - when:
- transponder mode selecter in TA ONLY or TA/RA, and
- a TCAS TA or RA occurs, and
- neither pilot has the TCAS display selected, and
- in CTR MAP, EXP MAP, VOR, APP

29
Q

TCAS Inhibits
- INCREASE DESCENT RA
- DESCENT RA
- RA
- ALL TCAS
- ALL TCAS

A

INC - inhibited below 1500 feet RA
DES - inhibited below 1100 feet RA
RA - inhibited below 1000 feet RA, below 1000 feet RA when TA/RA mode selected on transponder panel, TA only mode is enable automatically and TCAS message. TA ONLY displays on ND
ALL TCAS - voice annunciations are inhibited below 500 feet RA
ALL TCAS - inhibited by GPWS and wind shear warnings
