Q

What ensures the battery voltage check of 25,5V?

A

25,5V ensures charge above 50%

Q

How do you test the oxygen mask and what is the purpose of the test?

A
  1. Press the reset/blinker button -> blinker turns yellow then black.
  2. Press the reset/blinker and hold it together with the emergency pressure selector -> blinker stays yellow.
  3. press the emergency pressure selector only to ensure mask is not supplied anymore. No blinker indication.
  4. check regular low PR on door page is OFF

Q

When do u push the stick fully forward for takeoff?

How does this takeoff technique look like?

A
  • X wind > 20 kt
  • Tail wind

50%, rapidly to 70%, then above 15 kt ground speed progressively increase thrust to reach takeoff thrust by 40kt and hold it till 80kt.

Release it progessively till 100kt

Q

What is the initial speed after rotation?

A

V2+10

22
Q

When is the Nav accurecy check reliable?

A

<= 3nm FM is reliable.

Arc or Nav in lateral guidance possible

23
Q

When can we disregard the 15% margin on the FLD?

A

In unforeseen circumstances.

But LDR always < LDA

24
Q

What is the maximum tailwind limit and when do you have to adjust the config?

A

15kts maximum tailwind

Tailwind >10 kts config full!

25
Q

How much time do the speedbrakes need to retract >315kt?

A

25s

26
Q

When do you have to set flaps 2 latest?

A

2000ft/tdze or 6NM

If platform alritude < 2000ft set flaps 2 1 dot below

27
Q

Is there any action required when using the speedbrakes with flaps extended?

A

When using speedbrakes while flaps are extended it is necessary to recycle the autorhrust on the a319.

28
Q

How does an SRA approach work?

Sirveillance Radar Approach

A

Controller guidance until 2nm-0,5nm

Advisory Alt each 1Nm

If termination at less than 2nm, alt advisory every 0,5nm

Add a CF at 5nm from touchdown

29
Q

What are the stable approach criteria?

A

Aircraft should be stable by 1000ft and must be stable by 500ft

Aircraft in landing config
Correct lateral and vertical path
Speed +10 kt and -5kts
Max bank 15 degrees

At 1000ft max Vapp TGT +30 and landing conf
At 500ft stable approach criteria achieved + Landing checklist

For circling approach

-> by 400ft see approach criteria + within -+ 30 degree track

30
Q

How does a discontinued approach work?

A

Below FCU Alt, MauST do a Go-around.
Above FCU alt, discontinue app or go-around.

„Cancel approach“ -> disarm Approach PB

31
Q

When does the PM has to call out flight parameter deviations?

A 
Pitch + 10* and -2,5* (+7,5* a321)
Bank > 7*
Speed +10kts and -5kts
Decent rate > 1000ft/min
1/2 dot of V/DEV, GS, LOC, VOR
Vor 2,5*
NDB 5*
X-Track > 0,1nm
32
Q

When does the FMA change from CAT 1 to CAT3 dual for an ILS approach?

A

Below 5000ft

33
Q

Can non monitored items be disregarded below 1000ft?

A

Yes

34
Q

Can vertical guidance be used on an rnav approach after a temperature correction?

A

No

35
Q

What are the acceptable tolerances between MCDU and chart for an Rnav approach?

A

0,1* vertical

3* lateral

36
Q

How do you fly a nob-precision approach if you have to use TRK/FPA?

A

Stabilized

37
Q

How does the thrust lever affect the spoilers and the autobrake?

A

If the thrust lever are not at idle, no spoiler extension. No spoiler extension = no autobrake

38
Q

When do you have to disengage the autobrake?

A

Before 20kts

39
Q

Callout for a bulked landing?

A

„i have control“

„Toga“

40
Q

What are the brake temperature limitations you have to call maintenance for?

A

> 600 degrees or <60 degrees with 150 degrees difference between the same gear.

Difference >200 degrees on both gears

Temperature >900 degrees

41
Q

Why do you have to set the center tank pumps off before refueling?

A

To avoid fuel spillage or low pressure warning.

42
Q

What is the definition of a „steeper angle approach“ and how to fly?

A

3,5* -4,5*

Above 3,5* stabilised approach required.

43
Q

When is TO inhibit active?

A

80kt until 1500ft or 2 min after TO

44
Q

What is no good reason to reject the takeoff?

A

Exceeding EGT

Nose wheel vibration

45
Q

When does the deceleration light comes on?

A

At 80% of the deceleration rate selected.

46
Q

Below which speed is the Autobrake INOP?

A

72 kts

47
Q

What are the 3 Options to call for the SCCM in case of a problem?

A

„Sccm to the interphone“
„SCCM TO THE COCKPIT“
„Xxx“

48
Q

What are the callouts for a preplanned emergency landing?

A

At 2000ft „cabin crew take up landing positions“

At 500ft „brace brace“

49
Q

What is the callout for an unplanned emergency landing?

A

„Cabin crew, brace brace“

50
Q

What is the callout for an evacuation?

A

„Evacuate, unfasten your seat belts and get out“
