Autoland

Question 1

During autoland, should you use the flight directors or the actual localizer/glideslope indications to monitor the approach?

Answer 1

Raw data, not flight director

Question 2

Autolands can be made with flaps_____

Answer 2

25 or 30 only

Question 3

AFDS must display ______ for autoland

Answer 3

LAND 2 or LAND 3

Question 4

Minimum threshold crossing height for autoland

Answer 4

TCH: 44’

Question 5

CAT 1 autolands can be flown by _____. But CAT 2 and 3 must be flown by ___.

Answer 5

either pilot. But CAT 2 and 3 is CA only

Question 6

LAND 3 is considered fail______.

LAND 2 is considered fail______.

Answer 6

LAND 3: Fail operational

LAND 2: Fail passive

Question 7

Are we allowed to have autothrottles inoperative for autoland?

Answer 7

Yes, but only for CAT 1 and 2.

CAT III requires autothrottles

Question 8

Where can you find a good review for doing CAT II/III before attempting the approach?

Answer 8

QRH- CAT II/III Approach Review

Question 9

If the Autoland Status Annunciator (ASA) changes to NO AUTOLAND, what is required?

Answer 9

A missed approach

Question 10

During autoland, what happens at 25’?

Answer 10

Thrust levers retard and FMA changes to IDLE

Question 11

During autoland, what happens at 5’?

Answer 11

ROLLOUT is engaged.

Question 12

If the autopilot does not track centerline, the CA must____

Answer 12

Disconnect the autopilot and manually steer

Question 13

During an autoland with one engine inoperative, use rudder pedal input until _____.

Answer 13

1,500’ (then the autopiot takes care of the rudder)

Question 14

If you did go around during an autoland with an engine out, it would take care of rudder until____

Answer 14

another lateral or vertical mode is selected, or altitude capture. (reverts to 1 autopilot and you lose rudder input suddenly and abruptly)

Question 15

For crosswinds requiring more than 10 degrees of crab angle, runway alignment occurs at____.

Answer 15

500 AGL

Question 16

For crosswinds requiring a crab angle of between 5 and 10 degrees, runway alignment occurs at____

Answer 16

500 AGL (1st)

200 AGL (2nd)

Question 17

For crosswinds requiring a crab angle of less than 5 degrees, runway alignment occurs at_____

Answer 17

200 AGL

Question 18

What does “runway alignment” mean?

Answer 18

simply means a sideslip configuration (wing slightly low into the upwind side)

Question 19

What is the difference between normal autopilot runway alignment and engine out runway alignment?

Answer 19

Normal: slight bank sideslip

Engine out: Wings level sideslip (occurs at 1,300’ or engine out if lower than 1,300’ when it occurs)

Question 20

When does the autopilot flare on autoland?

Answer 20

50’

Question 21

What does fail operational and fail passive mean?

Answer 21

Fail operational: AFDS capable of completing ILS approach, autoland, and rollout if any single system fails after passing alert height (AH)

Fail passive: A single failure causes no significant deviation of airplane flight path or attitude. DA(H) is used

Question 22

What is a decision height versus a decision altitude?

Answer 22

DH = Radio altitude is controlling (CAT II)

DA = Barometric altitude is controlling (CAT 1)

Question 23

What is an alert height? (AH)

Answer 23

Used for CAT III. Radio altitude of 100 typically set. Used as a marker for above which certain failures must initiate a missed approach. Has nothing to do with visual reference.
