Q

Are both NORM ELEC STAB TRIM switches (on yoke) required to move the stabilizer?

A

YES

<em>*moving only one applies HYD PWR but does not release brakes. Both must be used and used in the same direction.</em>

Q

NORM STAB TRIM use w/AUTOPILOTS engaged?

A

Use during single AP operation will cause AP to disconnect.

Use during multiple AP operation (during approach) is inhibited.

Q

Describe the ALTN STAB TRIM system

A
  • Serves as backup to STAB TRIM
  • Also uses ELEC PWR at full rate
  • Provides increased range of input
  • Overrides ALL OTHER STAB TRIM inputs!
  • Moving both switches control both trim modules
  • Will NOT disconnect any AutoPilot
    • UNSCHED STAB TRIM ANNUNC

Q

Describe PES mode?

A

Provides limited STAB TRIM with failure of L + C HYD SYS in flight by using R HYD SYS to drive STAB using trapped L trim system fluid.

  • Activates automatically using R HYD SYS
  • STAB TRIM avail at 1/4 rate
  • Operated by normal column switches
  • ALTN + AP TRIM INOP

Q

UNSCHED STAB TRIM panel light indicates?

A
  • Uncommanded STAB TRIM operation
  • ALTN STAB engaged while A/P engaged
  • STAB moving in direction opposite of elevator

<em>*only ANNUNC on </em><em>panel</em><em> that generates MASTER CAUTION. All others are ADVISORY</em>

A

TL Advance

18
Q

SPOILERS panel light?

A

One or more spoiler pairs is INOP

19
Q

AUTO SPDBRK panel light?

A
  • Auto Arm System Fault
  • Do not ARM
    • They may deploy in flight
    • They may not deploy upon landing
20
Q

SPEED BRAKES panel light + SPEEDBRAKES EXT EICAS?

A

SPEEDBRAKES extended w/

  • FLAPS 25 or 30

or

  • AC below 800’
21
Q

YAW DAMPER INOP

A
  1. HYD SYS FAIL
  2. ELEC SYS FAIL
  3. IRS NOT ALIGNED (only 1 IRU required)
22
Q

RUDDER RATIO panel light?

A
  • SYS FAIL

The L HYD SYS rudder actuator depressurized

  • Rudder displacement limited at high airspeeds
    • Abrupt rudder inputs should be avoided
  • Full rudder displacement available at low airspeeds
23
Q

TEF/LEF per selected handle position?

A

UP = UP

FLAPS 1:

  • FLAPS UP
  • SLATS MID

FLAPS 5 - FLAPS 15 - FLAPS 20

  • FLAPS SET (AILERON DROOP)
  • SLATS STILL MID

FLAPS 25 - FLAPS 30

  • LAND FLAPS SET
  • LAND SLATS SET
24
Q

PRIMARY FLAP Protections?

A
  • LOAD RELIEF
  • TEF/LEF ASYM
25
Q

LEADING EDGE Panel light?

A
  • LEF DISAGREE
    • not driving towards new commanded position
    • most likely handle not in detent
  • LEF ASYM
    • HYD PWR automatically cut OFF to both LEF/TEF
26
Q

TRAILING EDGE Panel light?

A
  • TEF DISAGREE
    • not driving towards new commanded position
    • most likely handle not in detent
  • TEF ASYM
    • HYD PWR automatically cut OFF to both TEF/LEF
27
Q

ALTN FLAPS max extension?

A

FLAPS 20 ONLY

<em>*Go Around for FL25/30 would take too long</em>

28
Q

ALTN FLAP SYS does what?

A
  1. SHUTS OFF HYD POWER
  2. ENGAGES ELEC FLAP MOTORS
  3. ARMS ALTN FLAPS SWITCH
  4. DE-ENERGIZES FLAP HANDLE

<em>*no LOAD RELIEF or ASYM protections</em>

29
Q

Flap Handle Warning generated when?

A

Handle not in detent for more than 25 seconds

TE FLAP + LE FLAP DISAGREE will ILLUME
