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

Answer 25

select FD NAV mode

Question 26

when can we arm the approach in the FMS?

Answer 26

within 50nm of the airport

Question 27

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

Answer 27

to place the FMS into terminal phase early

Question 28

when will the FMS automatically arm the approach?

Answer 28

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

Question 29

can the FMS tune a ground based navaid?

Answer 29

yes, it will ask permission beforehand though

Question 30

what will we see 15 seconds before an automatic activation?

Answer 30

SCALE CHANGE

Question 31

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

Answer 31

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

Question 32

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

Answer 32

'radar vectors to final'

Question 33

after a manual activation when will the glideslope come alive?

Answer 33

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

Question 34

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

Answer 34

on downwind to avoid inadvertent leg sequencing

Question 35

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

Answer 35

approach type and availability of SBAS

Question 36

when will the FMS glideslope terminate?

Answer 36

missed approach point

Question 37

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

Answer 37

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

Question 38

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

Answer 38

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

Question 39

when may vertical guidance not be provided?

Answer 39

circling only approaches MAP after runway threshold glideslope angle too steep (max 7.76 degrees) glideslope angle too shallow (min 1.97 degrees)

Question 40

what does the FMS require to 'fly' an ILS?

Answer 40

- EFIS - FD - advanced autopilot

Question 41

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

Answer 41

when the pilot selects approach mode on the flight director

Question 42

when will the EFIS assume navigational control on an ILS?

Answer 42

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

Question 43

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

Answer 43

flight director approach mode

Question 44

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

Answer 44

NAV, after control has been transferred to the EFIS

Answer 48

channel number is being shown

Question 49

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