Q

What does GMS annunciation DR mean?

A

Dead reckoning mode, loss of navigation performance, loss of radio updating, and loss of position sensors for greater than 2 minutes

17
Q

What does FMS annunciation DGRAD mean?

A

The FMS has lost RNP, GPS is not available and is required for the selected flight plan procedure

18
Q

What does FMS annunciation APPR mean?

A

FMS is in approach mode operation. EDS sensitivity and FMS tracking gains are increased

19
Q

What does FMS annunciation TERM mean?

A

FMS is in the terminal area and operating under increased navigation accuracy

20
Q

What does FMS annunciation WPT mean?

A

FMA give WPT advisory 30 seconds prior to sequencing a waypoint

21
Q

What does FMS annunciation VTA mean?

A

The FMS is warning of an impending vertical track command. These include: within 1000’ of capturing an altitude constraint, 1 min prior to TOD, 1 min prior to resuming a climb or descent from a constraint waypoint, prior to resuming a VFLCH descent due to speed limit altitude level off, 1 min prior to executing a step climb

22
Q

What does FMS annunciation OFFSET mean?

A

It is an advisory that the FMS is flying an offset up to 30nm parallel

Q

At what point prior to the approach must the APPR annunciation turn on?

A

2nm before the FAF and must remain lit for the duration of the approach. Only for FMS flown approaches
