Abnormal Scenarios & Operations

Question 1

Flap/Slat Fault/Locked.
Points to remember.

Answer 1

Pull speed.
Overspeed warning based on actual slat/flap position.

Configuring in accordance with QRH:

SPD SEL…………VFE NEXT -5 kt - can be below manoeuvre speed as long as above VLS

The speed reduction and configuration changes should preferably be carried out wings level [FCTM]

Briefing topics from FCTM:
- Tail strike awareness

• The go-around configuration
• Any deviation from standard call out
• The speeds to be flown, following a missed approach
• At the acceleration altitude, selected speed must be used to control the acceleration to the required speed for the configuration.

Autoland not available!

Question 2

SMOKE CONFIG.
Points to remember.

Answer 2

May still land in ALTN/DIRECT LAW due IR 2 and IR 3 being unpowered in SMOKE config.
Note at end of ELEC EMER CONFIG SYS REMAINING table says can keep IR3 powered with ATT-HDG Selector switching which may lead to retaining NORMAL LAW.
This would reduce landing distance required (DIRECT LAW landing - CONF 3 only and VREF + 10/15 kt (depending on A/C type)

Question 3

Simple method for manual pressurisation

Answer 3

Could try and finesse it and follow the cabin alt vs aircraft alt schedule - difficult
OR
- Start the aircraft descending at a steady rate - ask ATC for constant descent all way down
- Look at what happens to cabin alt.
- Use blips on the manual cabin vs switch to keep the cabin alt constant.
- Maybe you can look at Cab V/S on Pressurisation page and select the opposite with Man V/S switch
(I think cabin alt will descend as go into denser air therefore need to blip “increase” cabin alt)
- Then when aircraft reaches cabin alt, fully open the outflow valve.

Question 4

What considerations need to be made with regards to landing with one reverser inop?

Answer 4

Can still use remaining reverser.

FCTM says select both reversers if one operative; thrust to idle if neither operative.

Autoland - can sometimes (?) only use reverse idle on remaining engine - see note below Autoland Wind Limit table in Operational Quick Access.

Question 5

In the event of NAV FM/GPS POS DISAGREE what do you do?

Answer 5

QRH procedure!

Question 6

Which emergency actions require cross checking by PF?

Answer 6

1) ENG MASTER
2) IR MODE Selector
3) All guarded controls
4) Cockpit CBs

Question 7

What is special about a dual slat channel fail?

Answer 7

A320 and A321: Alternate Law, Direct Law when gear down. AP and A/THR lost.

A319: Alternate Law when slats locked at 0 and select CONF2

There is a separate FCOM section for SLATS FAULT/LOCKED. Look at it in addition to FLAPS/SLATS FAULT/LOCKED
