CAT II & CAT III Flashcards
Can CAT II be landed manually?
No must be Autoland
What do you set the minima to?
Radio Altimeter to the DH.
What do you conduct a MAP for from commencing final approach to DH?
- NO AUTOLND is displayed on AFDS
- Malfunction in Airborne Equipment req’d for CAT II approach
- Failure occurs in GND facility (AUTOPILOT alert and master caution light will activate) On PFD LOC & GS modes will turn fail indication and deviation pointers will disappear.
When to conduct MAP at Approach Ban?
- RVR is less than the company minima applied to the Captain
- Any RVR on RWY is less then 200m CAT II
- Any RVR on RWY is less then 50m CAT III
When to conduct MAP at DH?
- LOC deviation exceeds 1/3 Dot (2/3 Dot on expanded scale) or
GS exceeds 1 Dot - If Airplane is not in a position where a continuous desent to to the intended RWY can be made at an appropriate ROD using normal manoeuvres.
- Visual reference not established
ALS cross bar, red terminating barettes or red side row barettes and segment of at least 3
RL or CL or
TDZ
When must a MAP be made below DH?
Any failure occurs
Approach can be continued if Capt decides the auto LDG could be accomplished safely
When RVR is less then 1200m what restrictions apply?
- RWY length needs to be 115% or longer than LDG field length (DRY)
(The LDG weight is at or lower than limit WT of WET)
OEI LDG weight is at or lower than the OEI field limit weight for CAT II & III - Max Crosswind is 10 kt used for the decision to land OEI
- Max crosswind 15kt 2 ENG
CAT II Minima?
200-100ft
300m RVR
Visual references?
One of- Cross Bar, RTHL, Barrettes of TDZ
And one of EITHER-
1- Segment of at least 3 consecutive lights of ALS. (Cross bar, red terminating barrettes or red side row barrettes is also visible)
2- RL or CL
3- TDZ
AFDS Annunciation?
Either LAND2 or LAND3 is displayed
NO AUTOLND is not displayed at or ABV 1500ft RA
PFD?
2 systems: Different ILS and Radio altitude sources are provided for PF and PM sides.
Means EICAS messages:

Forward Window Heat?
2 systems
- EICAS msg WINDOW HEAT L(R) FWD must not be shown.
- Not required when icing condition is not anticipated (20’c TAT is icing conditions in the air)
Marker Receiver?
1 system (Not required when approach does not require marker beacon)
