29
Q

RNP/LPV Appr.

LPV approaches use __________________________ input from the___________________for the initial portion of the approach?

A

Barometrically-corrected altitude; Air Data Computer(ADC)

30
Q

RNP/LPV True or False:

Minimums remain unaffected by temperatures during LPV approaches?

A

False
(Barometric altitude is used for LPV approaches)

31
Q

RNP/LPV:

If the OAT is significantly colder than ISA, what will the aircraft need to do before reaching the FAF?

A

Reduce vertical rate to reach FAF.

32
Q

RNP/LPV:

If the OAT is significantly warmer than ISA, what will the aircraft need to do before reaching the FAF?

A

Increase vertical rate to reach the FAF.

33
Q

The Flight Director(FD) computes……..

A

Roll and pitch commands to maintain a selected aircraft trajectory.

34
Q

FLIGHT DIRECTOR
What does the FD use as data source for flight guidance?

A

Left or Right Data Concentrator Unit (DCU)

35
Q

FLIGHT DIRECTOR

What does PFCC stand for

A

Primary Flight Control Computer

36
Q

FLIGHT DIRECTOR

What conditions does the Heading Knob automatically synchronize?

A
  1. When takeoff mode is active on the ground(TOGA button)
  2. When go around mode is active(TOGA button)
  3. When the AFCS reverts to basic mode
37
Q

FLIGHT DIRECTOR

When the FMS is the navigation source, how many miles, of the FMS course, does the FD calculate an intercept heading?

A

2.5 miles

38
Q

FLIGHT DIRECTOR

Half-bank mode limits the maximum bank angle used by the FD to:

A

15 degrees

39
Q

FLIGHT DIRECTOR
When is half-bank mode automatically activated

A

31,500 feet

40
Q

FLIGHT DIRECTOR
Flight Path Angle(FPA)

A

The FPA mode is the basic vertical mode. In the FPA mode the aircraft pitch changes to maintain the selected flight path angle.

41
Q

FLIGHT DIRECTOR
Vertical Speed mode (VS)

A

The VS mode changes the aircraft pitch to maintain a selected vertical speed(during climb or descent).

42
Q

FLIGHT DIRECTOR
Altitude Preselect mode(ALTS)

A

The ALTS mode is used to capture and maintain (level off) a preselected barometric altitude.

43
Q

FLIGHT DIRECTOR
Altitude hold (ALT)

A

The ALT mode is used to maintain a barometric altitude.

44
Q

FLIGHT DIRECTOR
Flight Level Change mode(FLC)

A

FLC is used to climb or descend while maintaining a selected airspeed or Mach number.

45
Q

FLIGHT DIRECTOR
Both Underspeed and Overspeed protection automatically activates in both:

A

Fly-By-Wire(FBW) Normal Mode & Primary Flight Control Computer(PFCC) Direct Mode.

46
Q

VERTICAL NAVIGATION INDICATION
How much, in feet, does each dot on the VNAV Deviation Pointer and Scale indicate?

A

250ft from the VNAV path(75 feet when approach mode is active)

47
Q

When does the Emergency Descent Mode(EDM) automatically activate?

A

If cabin altitude exceeds 14,500ft and the aircraft is above 25,000ft

48
Q

Auto Flight
Does FBW envelope protection have priority over any AFCS command?

A

Yes

49
Q

Auto Flight
The AP performs the following functions:

A
  1. Two Axis surface actuation
  2. Flight envelope protection
  3. Autotrim
50
Q

AUTOLAND
When is the only time the Autoland system is available?

A

During ILS approaches by selecting the (APPR) button on the FCP

51
Q

AUTOLAND
Define Fail Operational Autoland System (LAND 3)

A

Autoland system capable of completing an ILS approach, Autoland, and rollout following the failure of any single system component below alert height.

A CAT IIIB precision approach can only be flown with a fail operational Autoland system (LAND 3)

52
Q

AUTOLAND
Fail Passive Autoland System (LAND 2)

A

Autoland system, which in the event of a failure below 200 ft AGL, causes no significant deviation of aircraft flight path or attitude. The capability to continue the operation may be lost and an alternate course of action(i.e. a missed approach or manual landing) may be required.

A CAT IIIA precision approach can be flown with a fail operational (LAND 3) or fail passive Autoland system (LAND 2). A DH of 50ft or the published DH must be set for a fail passive Autoland approach.

53
Q

AUTOLAND
A fail operational Autoland system requires a higher level of redundancy than a fail passive system. What are they?

A

Three radio altimeters and three VHF NAV; fail passive only two of each.

54
Q

AUTOLAND
Where does the Autoland function reside?

A

In the PFCC.

55
Q

AUTOLAND
Are the PFCC’s independent from the AP?

A

Yes

56
Q

AUTOLAND
What contains the flight guidance and auto-throttle functions?

A

Data Concentration Modular(DMC)

57
Q

AUTOLAND
Define LAND 3

A

Fail operational Autoland capable aircraft.

58
Q

AUTOLAND
Define LAND 2

A

Fail passive capable aircraft.

59
Q

AUTOLAND
Define APPR 2

A

The aircraft may conduct an ILS CAT II approach or CAT I. Manual landing is required.

60
Q

AUTOLAND
Define APPR 1

A

The aircraft may only conduct an ILS CAT I approach. Manual landing is required.

61
Q

AUTOLAND
What is guaranteed with both APPR 1 & 2

A

Manual landing, since Autoland function is not available for these modes.

62
Q

AUTOLAND
Correct landIng configuration has to be set before________ft for the system to up-mode Autoland.

A

800

63
Q

Engine starting wind limitations maximum crosswind component?

A

43kts

64
Q

Engine starting maximum tailwind component?
