What are the some of the ELAC functions? QRM should be referenced.
- Normal elevator. - Normal aileron.- Normal pitch and roll.- Alternate pitch. - Direct pitch and roll. - Abnormal attitude. - Aileron droop.- Autopilot orders
What are some of the SEC functions? QRM should be referenced.
- Normal roll.- Speed brakes.- Alternate pitch.- Direct pitch.- Direct roll.- Abnormal attitude
What does the SEC 3 control?
- Spoiler Control - one flight spoiler and one ground spoiler on each wing.
What are some of the FAC functions?
- Rudder Trim.- Rudder travel limit.- Yaw control.- Flight Envelope Protection - vertical.- Windshear Protection.- Low Energy Warning Protection.- Alpha Floor Protection.- PFD speed scale.
What should happen to the THS after landing?
Reset to zero.
Describe some of protections a pilot will have in Normal Law?
- High Speed.- High Angle of Attack (AOA/alpha).- Load Factor Limitation (+2.5g / -1.0g).- Pitch Attitude (30° up/15° down).- Bank Angle (67°).
Describe High Speed Protection.
If VMO/MMO plus a predetermined factor is exceeded, the system induces a pitch-up input to limit aircraft speed.
What would a pilot have to do to override the high speed protection pitch-up?
Turn 2 ADRs off to force the aircraft into Alternate law.
What is alpha max?
The maximum angle of attack allowed in Normal Law, indicated by the top of the red strip on the airspeed scale.
How does High Angle of Attack Protection operate?
When the angle of attack exceeds alpha prot, pitch trim ceases and angle of attack is now proportional to side stick deflection, not to exceed alpha max even with full aft side stick deflection.
What protections does a pilot have in Alternate Law?
- Load Factor.- High speed stability.- Low speed stability.
What protections does a pilot have in Direct Law?
None.
When does flare mode activate in ALTERNATE LAW? Describe the whole process.
There is no flare mode if operating in ALTERNATE LAW. The aircraft proceeds directly from ALTERNATE LAW to DIRECT LAW when the gear is selected down, and flare mode will not be available.
If in Alternate Law, when will the aircraft revert to Direct Law? What might be a wise thing to do?
If the controls degrade to alternate law for any reason other than recovery from abnormal attitude, Direct Law automatically becomes active with gear extension with autopilots not engaged. In other words, let the autopilots work for you until you must disconnect them.
When is there a direct relationship between side stick and flight control surface deflection?
- When in Direct Law.- When below 100
It’s common Airbus philosophy that the Airbus cannot stall in NORMAL LAW. However, there are conditions in which it can. Describe how this can happen.
• Faulty Radio Altimeter
• A good pilot will operate under the philosophy that anything can happen.
Preventative systems such as (ALPHA PROT, ALPHA MAX, etc.) could
interpret bad data as valid data and subsequently fail to recognize the actual
angle of attack or flight path of the airplane. Therefore, it is hard to point to
exact scenarios when the Airbus can stall in NORMAL LAW. We need to
understand anything is possible and we should recognize stall indications
and recover regardless of the active control law.
After recovery from an unusual attitude, what control law would the aircraft likely be in?
• ABNORMAL ATTITUDE LAW
What is the purpose of Abnormal Attitude Law?
Allows the aircraft to be recovered from an unusual attitude.
How would you get into Abnormal Attitude Law?
By exceeding approximately double the Normal Law limits.
What PFD indications indicate Normal Law?
- Green = for pitch, bank, and overspeed limits.- Amber/black (alpha prot) airspeed tape.
What is the ADIRS?

What are some of the parameters the IR provides?
Attitude, FPV, Track, Heading, Acceleration, Angular Rates, GS and Aircraft Position.
If there was an IR1/ADR1 FAULT, what should be done with the switching panel to display backup data appropriately?
• ATT/HDG to Capt 3
If the AIR DATA portion of the #1 ADIRU failed, what should be done with the switching panel to display backup data appropriately?
• Air Data to Capt 3

What is the importance of observing the ADIRS ON BAT light?
- It confirms the ADIRS ability to revert to aircraft battery power.
What are some indications of an ADIRU having reverted to battery power on the ground?
- An external horn sounds.- An ADIRU and AVNCS blue light illuminates on the External Power Panel.
What is the significance of a steady FAULT light on the IR?
- IR has failed and cannot be recovered.
What is the significance of a flashing FAULT light on the IR?
Navigation function is lost. Attitude and Heading may be recovered in ATT mode.
What could cause the flashing white ALIGN light to illuminate on the ground?
- Position - PPOS not entered within 10 min. of alignment or within 3 minutes of fast-alignment.- Place - Large difference in LAT/LONG between shutdown position and entered position -1°.- Push - Aircraft movement during alignment.- No align light on A320 -The E/WD memo section displays IRS IN ALIGN during alignment and replaces ALIGN lights on the overhead panel. This memo flashes in green for the same reasons as the ALIGN lights flash on the other aircraft.
Describe what will happen if an ADR is selected OFF?
- The pilots would lose barometric altitude, airspeed, mach, angle of attack, temperature and over speed warnings from that one ADR.- The ECAM would instruct the pilot to select the AIR DATA SWTG to CAPT 3 or F/O 3 as appropriate.- At that point the pilot’s affected side would return to normal.
What functions are lost when an IR is turned OFF?
- The pilot would lose the IR part (Inertial Reference) which supplies attitude, flight path vector, track, heading, accelerations, angular rates, ground speed, and aircraft position.- Along with all the ADR information.- The ECAM would instruct the pilot to select the ATT HDG SWTG to CAPT 3 or F/O 3 as appropriate.- At that point the pilot’s affected side would return to normal.

FUEL Panel How come sometimes the fuel totalizer reads 42,200 on ECAM when fueled to MAX capacity?
The fuel can expand by 2% without venting overboard.
How many fuel pumps are there and where are the fuel pumps located?
• There are seven total fuel pumps: two center tank pumps, four wing tank• The APU pump is used when fuel feed pressure is low (due to loss of tank
pumps or loss of normal AC electrical supply).
Explain the flow of fuel from before engine start to taxi out. (Assume full tanks) No jet pumps
-Engine start = wing tanks-After start = 2 minute center tank test -Take off = Wing tanks-At slats zero = center tanks run until empty (+5 minutes)-if slats extend again with fuel in center, center pumps go off.-Outer tanks open when main = 1650#

- Failure of the AUTO mode.- Center tank has more than 550 lb and either wing tank has less than 1100 lb.
How would a pilot know that fueling is in progress?
REFUELG message appears on the ECAM
Does this mean that fuel is entering the tanks?
NO. It means the refueling fuel door is open
What if this IDG cooling return fuel fills the wing tanks with the center tanks feeding?
The center tank pumps will cut off until the wing tank quantity is reduced by 1100 lb.
What is the approximate fuel capacity of each outer fuel tank (A319/320)?
Approx. 1,500 lb.
When do the main tank outer cells drain into the inner tanks (A319/320)?
When the inner tank quantity reaches 1,650 lb.
