When does G/A thrust become the reference thrust during an approach?
-Flaps out of up
or
-G/S intercept
When does TOGA mode arm?
-Flaps out of up
or
-G/S intercept
The localizer must be within ____ degrees to capture, and the glideslope must be within ____ degrees to capture.
LOC: 120 degrees
G/S: 80 degrees
Note: LOC first, followed by G/S
On approach, what happens at 2,500 RA?
-GPWS callout
-RA displays
On approach, what happens at 2300’?
ALL PWS alerts inhibited until 1200 RA
On approach, what happens at 1,500’?
-AUTOLAND engages
-LAND 3 annunciated
-ROLLOUT and FLARE armed
-Electrical isolation
On approach, is there any significance to 1,300’?
Not normally. But if you had 1 engine inoperative, 1,300’ is where it would sideslip.
On approach, what happens at 1,200’?
PWS inhibit ends
What happens at 1,000’ RA?
-GPWS callout
-TCAS RAs inhibited until greater than 1,000’ on go around
On approach, what happens at 500’ RA?
AFDS first runway alignment (sideslip)
On approach, what happens at 400’ RA?
New PWS CAUTIONs are inhibited
On approach, what happens at 200’ RA?
-LAND 3 degrade to LAND 2 annunciation inhibited
-AFDS 2nd runway alignment
On approach, what happens at 50’?
-The aircraft flares
-New PWS WARNING inhibited
On approach, what happens at 25’ RA?
Power set to IDLE
When does the AFDS begin ROLLOUT?
5 RA
