A320 General by Mehrdad TE Flashcards
When you turn the mode selectors to NAV, what are you looking for on the panel?
Ensure that each ADIRU has the ability to revert to the batteries by observing the BAT light illuminating for several seconds.
What emergency equipment items are located in the cockpit?
4 Oxygen masks/smoke Goggles 4 Life Jackets 4 Fire fighting items - crash ax - halon - PBE - Gloves 2 escape ropes 2 flashlights
What does the ON BAT light indicate?
It is illuminated amber if one or more IR(s) is supplied by aircraft battery. Also illuminates briefly during the beginning of a full alignment.
How long will each ADRIU stay on battery power?
ADRIU 2 & 3 will remain on battery power for 5 minutes to hold alignment until a generator can be restored. ADRIU 1( ADRIU 3 if captain selected ATT HDG CAPT 3) will remain on battery power until generator power is restored or the batteries fail.
What info is provided by the “IR” units?

What does a steady white ALIGN light indicate?
The respective IR is in the Align mode
What does a flashing white align light mean?
- No present position entered within 10 min of NAV selection (no position)

What does it mean when the IR lights are extinguished?
Alignment has been completed.
How do you fast align an IR?
Turn the IR mode selectors OFF momentarily (not more than 5 seconds) and then back on.
What does steady illumination of the amber IR FAULT light indicate?

What does flashing illumination of the amber IR FAULT light indicate?
Attitude and Heading may be recovered in ATT mode (you have lost the navigation portion).
What does the amber ADR FAULT light indicate?
A fault is detected in the Air Data Reference portion
Does turning the IR to OFF also turn off the ADR?
Yes
Can you turn the ADR OFF and still have the IR?
Yes
What would be missing on the on the Captain’s PFD if IR 1 failed or was turned OFF?
Attitude and navigation information
What action would recover the attitude and navigation information?
Selecting CAPT 3 on the EIS switching panel ATT/HDG selector
Selecting CAPT 3 on the EIS switching panel ATT/HDG selector
Input Heading (ex. 180.0) on the IR panel every 10 minutes.
With the loss of ADR 1, what would be lost on the Captains PFD?
Airspeed and Altitude information.
What would restore the lost altitude and airspeed information?
Selecting CAPT 3 on the EIS Switching Panel AIR DATA Selector
How do you normally enter Present Position into the IR?
Insert the Lat/Long on the MCDU INIT page
Then press Align IRS
Describe a post flight ADIRU accuracy check?
Select Position Monitor Page. Verify position deviation is < 5 nm for each ADIRU.
Verify residual ground speed on each ND (ATT HDG CAPT 3 for IR 3) is < 15 knots. (FCOM 3.03.25)

Normal elevator and stabilizer control Normal aileron control Normal pitch and roll Alternate pitch Direct pitch and roll Abnormal attitude Aileron droop Acquisition of autopilot orders
Under Normal Law, what does ELAC 1 control?
Primary - Aileron control (roll)
Standby - Elevator / Trimmable Horizontal Stabilizer control (backs up ELAC 2)
Provides 5” aileron droop
Under Normal Law, what does ELAC 2 control?
Primary - Elevator / Stabilizer (pitch)
Standby - Aileron control (backs up ELAC 1)
What backs up ELAC 2?
ELAC 1 -> SEC 2 -> SEC 1
What does SEC stand for?
Spoiler Elevator Computer
How many SECs are installed?
3
What functions are performed by the SECs?
Normal roll (by controlling the spoilers)
Speed brakes and ground spoilers (SEC 1 & 3 only)
Alternate pitch (SEC 1 & 2 only)
Direct pitch (SEC 1 & 2)
Direct roll
Abnormal attitude
Under Normal Law, what do the 3 SECs control?
Primary - Spoiler control (roll)
Standby - Elevator / Stabilizer control (SEC 1 & 2 back up the ELACs)
What is the sole purpose of SEC 3?
Spoiler Control
What is the definition of FAC?
Flight Augmentation Computer
How many FACs are installed?
2
What are the functions of the FACs?
Normal roll (turn coordination and yaw damping)
Rudder trim
Rudder travel limit
Alternate yaw
Under Normal Law, what do the FACs provide (YAWL)?
Yaw Control - Damping and turn coordination, rudder limiter, rudder trim)
Airspeed Protection Computation (Alpha Prot, high / low limits, maneuvering speed, PFD speed scale)
Windshear protection
Low Energy Warning Protection (“SPEED, SPEED, SPEED”)
Is full rudder deflection available during all flight regimes?
No. Rudder deflection is limited as a function of airspeed.
What is the computer and priority for the Ailerons?
ELAC 1 -> ELAC 2
What is the computer and priority for the Elevator and Trimmable Horizontal Stabilizer?
ELAC 2 -> ELAC 1 -> SEC 2 -> SEC 1
How are the flight control surfaces controlled and actuated?
All surfaces are controlled electrically and actuated hydraulically.
When is automatic pitch trim available?
