On power up, what if the battery is below 22.5V but equal to or above 21.0V?
You can recharge battery - see SOPM. Below 21.0V call maintenance.
The APU is started approximately ___ minutes prior to pushback, unless required for passenger
comfort.

Packs should be ____ when a ground air source is being utilized.
OFF
H-PBIT runs automatically when…
…all 3 hyd systems are pressurized for at least 1 minute and reservoir temp greater than +10C.
(1 min, 1 way to interrupt)
H-PBIT is interrupted when…
…any flight control surface is moving during the test. (1 min, 1 way to interrupt)
E-PBIT runs automatically when…
…an initial AC source is introduced. (3 min, 3 ways to interrupt)
E-PBIT is interrupted when…
…any hydraulic pump is running, flight control mode panel switches cycled, AC power interrupted. (3 min, 3 ways to interrupt)
How do you force a E-PBIT to run?
- Power down using Leaving the Airplane Checklist.
- Wait 1 minute.
- Perform power up using Safety and Power Up Checklist.
- Wait 3 minutes for E-PBIT to run.
- Perform H-PBIT when required.
How do you force a H-PBIT to run?
- Don’t move any flight control surface.
- STEER OFF EICAS displayed.
- Confirm all 3 hydraulic systems are below 250 psi and temps above 10C.
- Load 27.2 = 3A, 1, 2 turn the electrical pumps on in that order.
- Wait 1 minute.
- Turn off the pumps.
When do you need to do the SOPM hydraulic system warm up?
Reservoir temp below -18C.
When the smart probes are contaminated with ice or snow…
…turn ON ADSP Heater Switch. Make sure the PBITs run…see SOPM.
Conditions conducive to icing exist on the ground and for takeoff when…
…the OAT is 10°C or below, when operating on ramps, taxiways, or runways where surface snow, ice, standing water, or
slush may be ingested by the engines or freeze on engines, nacelles, or engine sensor probes.
A Cold Weather Preflight inspection must be performed…when:
- The OAT is 5°C or less, or
- The wing fuel temperature is 0°C or less, or
- Atmospheric conditions conducive to icing exist, or
- The aircraft has remained overnight and may have frozen contaminants due to exposure to
frost or precipitation, which could involve the entire airframe, or - On any through flight where residual ice from the inbound flight may have accumulated on
airframe surfaces or components, or - Cold soak ice is suspected in the fuel tank area.
Thin layer of frost underneath wing ok?
Yes…A 3 mm (1/8 in) frost layer is permitted on the underwing surfaces. A thin layer of
hoarfrost is permitted on the fuselage provided the layer is thin enough to distinguish surface
features underneath, such as painting and markings.
Engine 1 is normally started first and utilized for single engine taxi. When the crew elects to
taxi single engine on engine 2, electric hydraulic pump 1 selector knob must be…
…turned ON.
Once engine 1 is running, turn electric hydraulic pump 1 to AUTO.
After second engine start, verify the EICAS N1 target value is…
…+0.5% to -0.1% of the
ACARS or release N1 value. For example, if the ACARS / release N1 value is 90.0, then the N1 target on the EICAS must be 89.9 to 90.5.
When it is necessary to perform an engine start with a tailwind, monitor N1. When there is no
positive increase of N1, before starter cutout (50% N2), the start must be…
…manually aborted.
When oil pressure is not indicated by the time idle rpm is achieved…
…conduct an
immediate shutdown of the engine.
Although FADEC provides automatic over-temperature protection and automatically aborts the
start in the event of a hot start, hung start, or no light off, the engine start must be manually
aborted when:
NNoTM*/HHN ( Seven!)
- No positive oil press w/in 10 sec after N2 increase.
- No N1 increase at starter cutout (~50%N2) when starting with TW.
- No ITT indication within 30 seconds of fuel flow (no light off).
- ITT exceeds 815C (hot start).
- Oil Pressure stabilizes outside of green range.
- N1 or N2 fail to accelerate to stable (hung start).
- Intermittent elec or pneu start malfunction occurs before starter cutout.
When an automatic abort occurs or engine start is manually aborted due to abnormal
engine indications, its cause…
…must be investigated and corrected before further attempts
to start the engines.
In case of an automatic abort due to an engine hot start and with no ENGINE
EXCEEDANCE EICAS message….
…two additional engine starts are allowed. (but you should probably call maintenance…unless your FO f’ed up cross bleed is a good example).

For FOD prevention and damage to other aircraft and equipment in close proximity, limit the
thrust to…
…40% N1, as much as possible, and avoid rapid accelerations and decelerations.
Capt, when would you NOT SE taxi?
- Contamination.
- Maneuvering room marginal.
- <5 min taxi time.
- Airport forbids SE taxi.
- Risk personnel injury or equip damage.
- Capt’s call.
Also consider: slope, weight, 2 min warm up.
During ground operations of more than 30 minutes in icing conditions, or when increased fan
vibration due to fan ice accumulation is present, the engine thrust may be increased at 30 minute
intervals to approximately…
..54% N1 and held at that thrust level for 30 seconds, or until the fan
vibration level returns to normal. When airport surface conditions and the concentration of other
aircraft do not permit the engine thrust to be increased to 54%, set an acceptable thrust level
and time interval that is safe and practical.
Normal Takeoff Procedure (up to 10 kt tailwind):
40% N1 (with or without brakes), stable. Advance to TO/GA.
Normal Takeoff Procedure (up to 11-15 kt tailwind):
A/T disarmed. Apply brakes and advance thrust to 60% N1. Stable. Release brakes, Arm A/T / TO/GA detent before 60 kt.
Static Takeoff (SNA):
Apply brakes. 40% N1, stable. TO/GA detent. Release brakes at takeoff N1 target.
The use of Flex Thrust Takeoff is prohibited given the following operational constraints:
- Takeoff on contaminated runways.
- Reported or forecast windshear.
- When a special departure procedure specifies full thrust for takeoff.
