17
Q

What is associated with MODE 1 GPWS?

  • Excessive
  • Active below
  • Is caused by
  • Broadcasts
    • 1
    • 2
A
  • Excessive Barometric rate of descent
  • Active below 2500ft
  • Barometric rate of descent 3 times greater than radio height
  • Broadcasts
    • SINK RATE, SINK RATE
    • WHOOP, WHOOP, PULL UP
18
Q

What is associated with MODE 2 of the GPWS?

A

Caused by reducing radio altitude and ground rising from beneath

Broadcasts

  • TERRAIN TERRAIN
  • WHOOP WHOOP PULL UP. (If situation worsens)

This continues until radio altitude has stopped reducing and an increase of 300ft Baro altitude is registered.

19
Q

What is associated with MODE 3 of the GPWS?

A
  • Warns of barometric height loss after a take off or go around
  • The flap selectors must be moved away from the land position
  • Gear up must be selected
  • The alert is “DON’T SINK, DON’T SINK”
  • There is no warning.
20
Q

What is associated with a MODE 4 of the GPWS?

A
  • The proximity to the ground without appropriate gear and flap selections.
  • At high speed to inform the pilot of ground proximity and will broadcast the alert “TOO LOW TERRAIN”
  • At lower speeds if close to the ground the system will tell the pilot of the unusual situation with the alert:
    • TOO LOW GEAR
    • TOO LOW FLAPS
  • Many authorities regard the high speed situation as a warning and immediate climb action is required.
21
Q

If the BELOW G/S is pressed before an approach what happens?

A

The MODE 5 Alert will be inhibited and will reactivate on a go around.

22
Q

TAWS shows terrain _____ below the aircraft.

A

2000ft

23
Q
A
24
Q

What are the three calssifications of warnings and alerts?

A
  1. Genuine
  2. Nuisance
  3. False
25
Q

The stall is a function of ______, rather than?

A
  • Angle of Attack or Alpha
  • Not Pitch Angle
26
Q

When TOGA thrust is selected and stick hard back what will the aircraft do?

A

Clmb at max alpha conducting automatic terrain avoidance manoeuvre

27
Q

At low altitudes the aircraft will reach ___1___ first but at high altitude ___2___ will be reached first.

A
  1. Vmo
  2. Mmo
28
Q

TCAS is requried on all…..

A

All new aircraft with:

  • 19 Passengers or more
  • MTOM 5700kg

Requrie atleast TCAS II

29
Q

If an aircraft is with in 35 to 48 seconds of entering the collision what is broadcast, and this is known as?

A

“TRAFFIC, TRAFFIC” Is broadcast

Its a Traffic Advisory TA

30
Q

RA are Resolution Advisories and require?

A

Immidate action of either a CLIMB or DESCEND as broadcast by TCAS

31
Q

Resolution Advisories are broadcast when an aircraft is ________ from the collision zone.

A

15 to 35 seconds

32
Q

What is the range of TCAS outside terminal areas?

A
  • 30nm
  • +- 2700ft
33
Q

Proximate traffic on the TCAS system is an aircraft that is?

A

With in 6NM and 1200ft that is not transponding a TA or a RA

34
Q

The DFDR stores date for how many hours?

A

25 hours

35
Q

The DFDR is powered up (3) when?

A
  • After 5 minutes of the aicraft receiving power
  • On the ground when there is 1 engine running
  • In the air at all times
36
