Systems Flashcards
Departing KDAL during your initial climb, the following lights illuminate: Hydraulic System B ELEC 1 and ENG 2 LOW PRESS lights, STBY RUD ON, B Flight Control LOW PRESSURE, FEEL DIFF PRESS, the Master Caution lights, FLT CONT and the HYD Master Caution annunciators.
What is the initial course of action upon illumination of the Master Caution and associated lights?
Maintain aircraft control and continue flying the departure, thus reducing Task Loading.
Departing KDAL during your initial climb, the following lights illuminate: Hydraulic System B ELEC 1 and ENG 2 LOW PRESS lights, STBY RUD ON, B Flight control LOW PRESSURE, FEEL DIFF PRESS, the Master Caution lights, FLT CONT and the HYD Master Caution annunciators.
In this situation, which four systems directly affect the return and landing?
Auto slats and leading edge flaps and slats
Trailing edge flaps
Number 2 thrust reverser
Normal brakes
B REAL TOY BAAT L
A/P B, Rudder, Elevator, Aileron, Leading edge devices (normal), Trailing edge flaps (normal), certain flight spOilers, Yaw damper, Brakes (normal), Auto slats, Alternate nose wheel steering, Thrust reverser, Landing gear transfer valve
With loss of System B, which components are backed up by the Standby Hydraulic System?
Leading Edge devices
Number 2 thrust reverser
Departing KDAL during your initial climb, the following lights illuminate: Hydraulic System B ELEC 1 and ENG 2 LOW PRESS lights, STBY RUD ON, B Flight control LOW PRESSURE, FEEL DIFF PRESS, the Master Caution lights, FLT CONT and the HYD Master Caution annunciators.
Which QRH checklist is called for?
Loss of System B
As you prepare to extend the flaps with the ALTERNATE FLAPS extension, what is a future consideration regarding the LE Devices.
Once extended, they cannot be retracted.
To what position do the LE Devices extend when using Alternate Flaps?
Full extend
How are LE Devices and TE Flaps extended with a loss of System B Hydraulics?
LE Devices – Standby hydraulic system
TE Flaps – Electrically driven unit
What is the maximum speed allowed for an alternate flap extension?
230 knots
How long does the alternate flap extension take to deploy TE Flaps to 15?
Approximately 2 minutes.
Do you have asymmetry and skew protection when using the alternate flap extension?
No. The Flight Deck Crew must monitor the flap extension for any asymmetry or condition that may develop while the flaps are in motion during the alternate extension process.
Are autobrakes available with alternate braking?
No, autobrakes are only available with the normal braking system which is powered by System B Hydraulics.
Is antiskid protection available with alternate braking?
Yes, antiskid protection is available with both Normal and Alternate Braking systems.
Note: The antiskid system controls wheel lock with the left and right wheel pairs rather than individual wheels.
What four protections are provided by the antiskid system?
- Skid
- Locked wheel
- Touchdown
- Hydroplane
Is antiskid available with the loss of both A and B Hydraulic Systems?
Antiskid protection is available even with the loss of both hydraulic systems.
You are on short final at KMDW with a fuel state of 8.0, and the ANTISKID INOP light illuminates at 400 ft. AGL. What action should you take?
Execute a go-around. When time permits, refer to the QRH.
What are three considerations as you touchdown and prepare for braking with the ANTISKID INOP?
- Do not apply the brakes until the nose wheel is on the ground and the speedbrakes have been manually deployed.
- Use minimum braking consistent with runway length and conditions.
- Brake initially using light steady pedal pressure. Increase pressure as ground speed decreases and don’t pump the brakes.
What is the condition called when one wing device does not align with its associated device on the other wing?
Asymmetry
What is the condition called when symmetrical TE flaps do not operate at the same rate?
Skew
What aircraft computer provides protection for asymmetry and skew by monitoring the position of the wing LE and TE high lift devices?
Flap Slat Electronic Unit (FSEU)
How does the FSEU protect the aircraft from a TE skew condition?
The FSEU automatically protects against roll by maintaining flap symmetry.
What does a Trailing Edge Flap Disagree look like?
The trailing edge flaps are not in the commanded position.
What does a Trailing Edge Flap Asymmetry look like?
An uncommanded roll occurs when the flaps change position and/or the left and right flap indications disagree.
Why does the QRH avoid using the ALTERNATE FLAPS switch in an asymmetry condition?
There is no asymmetry protection provided when using ALTERNATE FLAPS extension.
If the ALTERNATE FLAPS switch is used, what effect does drag penalty have on flight planning if required to divert to an alternate airport?
The drag penalty (with the leading edge devices extended) could make it impossible to reach an alternate field.
