16
Q

What happens to A/THR if the Thrust Levers are moved to IDLE?

A
  • A/THR disconnects

- A/THR Blue

17
Q

What happens if the A/THR disconnect buttons are pressed for more than 15 sec?

A

A/THR disconnects for the remainder of the flight

All A/THR functions including alpha-floor are lost

18
Q

What happens to the thrust setting if you disconnect the A/THR with the disconnect buttons?

A

It will go to the thrust corresponding to the thrust lever setting

19
Q

If the levers are set to CLB and A/THR is active, what happens if you move the levers forward of the CLB detent?

A

active -> armed
A/THR blue on FMA
Thrust levers control thrust directly
“MAN THRUST” in white

20
Q

At what RA does one hear “RETARD”:

On an autoland?

On a manual landing?

A

10 ft RA

20 ft RA

21
Q

What is the minimum speed possible with A/THR ON?

A

VLS (Lowest Selectable)

22
Q

What is Ground Speed MINI?

A

Vapp - Twr HeadWind. It keeps the aircrafts energy constant until Touch Down

23
Q

What does a temporary white box around a mode indication mean on the FMA?

A

This new mode will be active in 10 sec

24
Q

When does LAND appear on the FMA?

A

On an ILS approach (GS and LOC) 400’ RA

25
Q

What is the only way to get out of LAND mode?

A
  • TOGA
26
Q

When do you get the message DECELERATE?

A

When you overshoot the TOD (calculated by FMGC)

27
Q

Why do you get the message MORE DRAG?

A

The aircraft is above the vertical profile and predicts that with an IDLE descent, the profile will be intercepted

28
Q

When can “SPEED, SPEED, SPEED” be heard?

A
  • 2000’ RA and 100’ RA
  • The system predicts a loss of energy and that thrust has to be increased to maintain your flight path and pitch attitude
29
Q

What triggers alpha-floor?

Does A/THR need to be active?

A
  • High AoA

- NO

30
Q

When is Wind shear protection available?

When is it triggered?

What do you see and hear?

A
  • TO: 3 sec after lift off until 1300’ RA with at least config 1
    LND: 1300’ RA until 50’ RA with at least config 1
  • When the FAC’s calculate that the energy level will fall below a certain threshold
  • Red “WINDSHEAR” message on both PFD’s for a minimum of 15 sec and an aural voice announcing “WINDSHEAR” three times
31
Q

When is ALPHA-FLOOR available?

A

from lift-off on TO until 100’ RA before landing

32
Q

What causes the memo “SPEED BRK” flashing amber to appear?

A

At level OFF with speed brakes extended, N1 >50% N1 (speed brakes should be retracted)

33
Q

What happens on the PFD altitude tape when the aircraft descends below the MDA?

A

AMBER RA

34
Q

What is displayed in the top centre of the ND?

A

Runway name and type of approach selected when within 250 Nm of the destination

35
Q

What does a triangle mean after a waypoint?

A

Mandatory overfly point

36
Q

What happens if you overfly a MAGENTA D in managed navigation?

A

Aircraft will start to decelerate towards Vapp

37
Q

What is the effect of activating the approach phase?

A

In managed speed it will decelerate to green dot speed

38
Q

After a Go Around, what will be strung in the F-PLAN page?

A

Another approach (the same as before)

39
Q

What happens to the RA indication during a CAT III A approach with decision height 50’ RA?

A
