767 Flashcards
767 Load Alleviation
767 (Winglets) Speedbrake Load Alleviation system
operates in flight when these conditions occur at the
same time:
– Flaps are UP
– Gross weight is greater than 340,000
– Indicated airspeed is greater than 320 kts.
– If lever is beyond the 50% position it will
automatically move to 50% position
– If lever is down it will be restricted to 50% position
System deactivates when gross weight less than
339,000 lbs or airspeed becomes less than 315 kts.
SPEED BRAKES EXT MESSAGE:
- Speed brakes extended during descent between 800
ft and 15 ft RA
(Vol 2 now says 800 ft or below) or with flaps greater
than 20 deg (Vol 2 says flaps are in a landing position)
What is powered if on BATTERY POWER ONLY:
What are the visibility and DH restrictions for the raw data approach?
- Hot Battery / Battery / Standby AC / Standby DC
buses. (with hydraulic pressure the flaps work, but flap
indicators do not). - Min weather: RVR 2400 (1/2 mile – 750 M) and a
DH of 250 or higher (ILS raw data)
Load Alleviation 757
Gross weight is greater than 221,000 lbs
- Indicated airspeed is greater than 330 kts
– If lever is beyond the 50% position it will
automatically move to 50% position
– If lever is down it will be restricted to 50% position
– System deactivates when gross weight less than
220,000 lbs or airspeed becomes less than 325 kts.
STANDBY POWER:
- If selector is in AUTO:
Transfers standby busses to battery power if normal
AC power is lost.
STANDBY POWER:
If Manually selected to Battery.
Selecting BAT directly powers standby busses from
the main battery.
GROUND HANDLING BUS:
When is it powered?
Only powered on the ground either by the APU or
available External power.
GROUND HANDLING BUS: What does it power?
Powers the cargo compartment doors and lights,
cargo handling equipment and airplane refueling.
GROUND SERVICE BUS:
What powers it?
Powered from right main AC bus.
- If right main AC is not available (on the ground), the
ground service bus can connect to and be powered
from APU / External power via the ground service
switch on F/A panel at 1L.
What does the GROUND SERVICE BUS power?
Powers two battery chargers, equipment cooling fan,
left forward fuel boost pump (+L Fwd door on 767).

ENGINE COOL-DOWN:
- 757: 1 minute.
- 767: 3 minutes
PRESSURIZATION AUTO INOP LIGHT:
Mode selector in MAN or Auto 1 and 2 Pressurization
Control failed.
ENG OVHT MESSAGE
- Engine bleed air leak in the engine nacelle area.
- 767-300 ER also has strut duct leak detectors
AIR CONDITIONING PACK CONTROLLERS: What temperature are they seeking?
Adjust output to satisfy the zone demanding the
coolest temperature.
PACK INOP LIGHT:
- (QRH allows attempts to recover)
- Pack controller fails
- Excessive pack outlet temperature
- Select STBY N, allow to cool for 5 min, press to reset
PACK OFF LIGHT
QRH only allows recovery of PACK if due to engine
bleed air loss, then consider an alternate bleed air
source.
- No resets or Stby-N
- Excessive internal temperature (no reset or Stby-N)
ZONE TRIM AIR FAILURE:
If single zone: select OFF. Temperature for that zone
will be controlled by the zone requiring coolest temp.
What are the indications for a EQUIPMENT COOLING OVHT while on the ground?
- Light and ground crew call horn will sound (steady
horn) if the airplane battery is the sole source of
electrical power on the ground for more than 30
seconds.
OIL - MIN QUANTITY:
- Preflight: 14 Quarts OK (
APU STARTER DUTY CYCLE:
During normal operations, while on the ground or in
flight: 3 consecutive starts or attempts within a 60-
minute period.
- Capt’s Authority for additional unlimited starts during
abnormal or emergency conditions when airborne.
- To cancel an APU shutdown during the 60 second
cool-down period with the RUN light still illuminated go back to Start
APU FIRE PROTECTION 757
- APU will auto shutdown if on fire while on the ground
or in the air. - 757 will auto shutdown and auto discharge fire agent
if on fire while on the ground, both engines not running.
APU FIRE PROTECTION 767:
- 767: APU will auto shutdown but no auto discharge if
on fire while on the ground.
APU FAULT light
APU has automatically shut down
APU NOSE GEAR BUTTONS:
— Red: Push first, closes the APU fuel valve, trips
APU generator off, arms the bottle and silences the
APU fire horn.
— Black: Discharges APU fire agent bottle.
– (Intermittent horn during walk around is an APU fire
warning test or actual fire warning)
ENGINE FIRE SWITCH (looks like a Handle):
- Closes associated engine and spar fuel valves
- Closes associated engine bleed air valves
- Trips associated engine generator off
- Shuts off hydraulic fluid to engine-driven hyd pump
- Arms both engine fire extinguisher bottles
- Silences the fire warning bell
– If the Master Warning Lights and Bell do not work
during TEST?
push both master caution warning light
assemblies to reset the system.
Which bus provides Fire Protection?
Hot Battery Bus
Which bus provides Fire Detection?
Battery Bus
CARGO COMPARTMENT FIRE EXTINGUISHING:
767
- FWD and AFT cargo compartments have smoke
detectors. - Either cargo fire arming switch:
– Arms the fire bottles
– Silences fire bell
Turns off both cargo heat fans on the 767 - If FWD arming switch is pushed it will also:
– Turn off both recirculation fans
– Switch both AC packs to High Flow
Closes FWD cargo heat valve (767)
LAV SMOKE IS DETECTED:
- A horn, chime and / or a flashing lav light at F/A
station, no indication in the cockpit.
FLAPS 30 is recommended when landing:
- Breaking action less than good
- Tailwind
- Runway length less than 7,000 ft
- On a wet / contaminated runway
ALTERNATE FLAPS (electric operation, slower): 757
757 has LE SLAT asymmetry protection
- 757/767: LE Slats go to landing position when flaps
25 are selected, increasing stall margin.
- 757 does not have TE Flap asymmetry and load relief
Max ALT FLAP setting: 20 (in case of a Go-Around)
ALTERNATE FLAPS (electric operation, slower): 767
767 does not have LE SLAT asymmetry protection
- 757/767: LE Slats go to landing position when flaps
25 are selected, increasing stall margin.
767: Some have TE Flap asymmetry protection.
- Max ALT FLAP setting: 20 (in case of a Go-Around)
