Q

With the selector switch on the transponder to ‘ALT ON’ or ‘XPNDR’, what TCAS functions are available?

A

None, although your mode C/S alt reporting is on so other ac can react to you.

A

Manually set to 2, set to 1 if Capt PF.

46
Q

Auto tune will show the 3 letter identifyer on the PFD and ND. If the ID is wrong or the raw frequency is displayed, pilots must manually tune and identify from morse

47
Q

Where is VOR info displayed?

A

Bottom left and right of ND. Top left of PFD. On the RMI

48
Q

On the gnd how can posn updating be achieved?

DME/DME
VOR/DME co-loc LOC/DME co-loc
LOC only

50
Q

Dual freq DME is used for position update, how are frequencies tuned?

A

IRS 1 as long as there is battery power IRS 2 shuts down after 5 mins on DC only

64
Q

Do you need to select ALIGN on the IRS mode selector?

A

No, select straight to NAV, this will auto align before entering Nav mode

65
Q

What are the reasonability tests?

A
  1. your ppos entry vs the FMC origin airfield (>4nm = ‘VERIFY POSN’ and flashing ALIGN)
  2. your ppos entry vs earth rotation latitude calculation (must be <1 minute/60nm) if still disagrees = FAULT
66
Q

How is Ppos normally entered into the IRS?

A

Via the FMC CDU, manual type over or copy of GPS posn. It can be entered directly ino the IRS DU by selectign PPOS during align and overtyping

67

Should an IRS fail how can info from the good IRS be sent to the other DEU?

A

On the nav select panel selecting IRS both L or both R. this will trigger an amber ‘INSTR SWITCH’ caution on the ND/PFDs

68
Q

What are the min number of satellites for a 3D GPS posn?

A

4

69
Q

What are the min number of satellites if using RAIM?

You must press and extinguish the SELCAL light for further alerts on that frequency

74
Q

What is the function of the service interphone?

A

Allows multiple comm jacks around the external parts of the ac to be live, normally for maitenance. Normally selected off for flights, if left on will create interfearance on the cabin intercom.

75
Q

When is the CVR area mic active?

A

From start of 1st engine to 5 mins after shut down automatically, from swx on, if selected on

76
Q

If the green light is on on the CVR what does this mean?

A

It has failed the test. Should illuminate briefly and sound a tone through the jack, if connected, then go out if the black test button is pushed

77
Q

When the HF mic is keyed

87
Q
