25
Q

after a missed approach, what do we need to do in order to reconnect the flight director to the FMS?

A

select FD NAV mode

26
Q

when can we arm the approach in the FMS?

A

within 50nm of the airport

27
Q

what is the purpose of manually arming the approach between 30 and 50nm?

A

to place the FMS into terminal phase early

28
Q

when will the FMS automatically arm the approach?

A

when the aircraft enters the terminal area at 30nm from the airport

29
Q

can the FMS tune a ground based navaid?

A

yes, it will ask permission beforehand though

30
Q

what will we see 15 seconds before an automatic activation?

A

SCALE CHANGE

31
Q

what criteria must be filled for the approach to activate automatically?

A
  1. approach must be armed

2. angle of intercept or track error must be less than either 15 degrees or 80 degrees of the final approach course

32
Q

what are the words that will result in the need to activate the approach manually?

A

‘radar vectors to final’

33
Q

after a manual activation when will the glideslope come alive?

A

within the lateral cone of 20 degrees of the final approach course

34
Q

when on vectors following a missed approach, when should we activate the approach?

A

on downwind to avoid inadvertent leg sequencing

35
Q

what determines whether baro or SBAS is used for vertical guidance?

A

approach type and availability of SBAS

36
Q

when will the FMS glideslope terminate?

A

missed approach point

37
Q

what will the FMS do with the glideslope if step down altitudes are included?

A

the glideslope calculation ensures the glide will clear the step down fixes

38
Q

what if the step down fix is higher than the calculated glideslope?

A

the glideslope is recalculated to an angle that will clear the step-down fix

39
Q

when may vertical guidance not be provided?

A

circling only approaches

MAP after runway threshold

glideslope angle too steep (max 7.76 degrees)

glideslope angle too shallow (min 1.97 degrees)

40
Q

what does the FMS require to ‘fly’ an ILS?

A
  • EFIS
  • FD
  • advanced autopilot
41
Q

when will the EFIS give the signal to the FMS that it is ready to receive NAV to NAV info on an ILS?

A

when the pilot selects approach mode on the flight director

42
Q

when will the EFIS assume navigational control on an ILS?

A

when the FMS detects the localiser and it has received the transfer ready notification from the EFIS

43
Q

On a vectored ILS what must be armed before pressing the FMS intercept LSK?

A

flight director approach mode

44
Q

what flight director mode. should we use on an ILS if established but not cleared for the approach?

A

NAV, after control has been transferred to the EFIS

45
Q

what does LPV minima require?

A

SBAS

46
Q

what kind of minima do LPV and LNAV/VNAV approaches use?

A

DA

47
Q

on an RNAV approach what does the final approach segment data block contain?

A

approach specific information that allows the FMS to meet the requirements to fly to LPV minima

48
Q

on an RNAV approach what will let us know that the FASDB is in the FMS?

A

channel number is being shown

49
Q

can we fly to LPV minima if there is no FASDB?

A

no. LNAV/VNAV minima as long as the GPS has ellipsoid data

50
Q

where is the SBAS glideslope?

A

from the FAF to the runway threshold

51
Q

if the database doesn’t have required data for an LPV but we’re still covered by SBAS what will the glideslope be based on?

A

baro

52
Q

when can level of service not be changed?

A

after passing the FAF

53
Q

what will we see if SBAS requirements for VNAV fail at the FAF?

A

the FMS will flag VNAV

54
Q

when is LOS determined on an RNAV approach?

A

approach activation

55
Q

what must the pilot do if LOS is lost prior to the FAF?

A

select a lower LOS

56
Q

on an RNAV approach when will the FMS give a low altitude alert?

A

at or below the vertical protection level (164ft) +150ft

57
Q

what does a RAIM prediction predict?

A

satellite availibility and geometry to determine GPS accuracy

58
Q

where is RAIM prediction on the FMS?

A

FPL menu

59
Q

what do we need the RAIM to be for a 30 minute window for our approach?

A

APPR

60
Q

when will the aircraft go into a 5 minute coast segment?

A

if RAIM integrity is available until crossing the FAF

61
Q

what will the aircraft do in the 5 minute coast segment if RAIM integrity is downgraded to a 4 satellite situation?

A

continue following GPS guidance for up to 5 minutes

62
Q

what must we do if we get a GPS INTEG annunciation?

A

go-around
