Autoland Flashcards
GA fail operational
Above 1000 ft reset height - checken ob capability
Below 1000ft-200ft
-GA für master caution (single failures oder dual), continuous ils deviation warnings,engine malfunctions regarding Thrust
Below 200ft
-ga nur für Dual failures,no autoland,continuous ils warnings
Fail operational Boden call
Rollout
Fail passive
Kein GA für ils warnings (süßer continuous ) bis 200ft RA
Operational auch unter 200 ft keine GA
Fail passive
Unter 200 ft GA auch für Single failures !!
When bei psssive FD u unter 50 ft failed
Continue but min rvr required 300m for manual landing
Recommended flap setting unter CAT 1 Bedingungen
Flaps 40
Fail operational: check mfd wann
During preflight und bei approach prep
Mfd sagst no Land 3
Land 2 ok for autoland!
Rvr is Always controlling for low vis… with 0 vis you could shoot an approach legally…
But at tui with a vis below 800 m rvr has to be reported, and low vis operation in force
In Flight non precision Minima
can now land because ceiling is only for planning purposes in Non-precision approaches.
Bei 1000ft agl RVR/ vis 800 mok.. sonst GA
Yes, assuming you have the required visual reference not later than the MDA!
Cat 1 vis is?!
800 m!
Cat I minima is not allways 200 ft. - but it cannot be lower than 200 ft. (and its a DA(H) and not a MDA(H))
The same goes for the Cat II minima
And according to JAR OPS you can, once past outer marker or equivalent position, allways continue to minima.
Where RVR is not available, the pilot-in-command may derive an RVR value by converting the reported visibility for non-precision and Category I approaches only. Use your table for this e.g reported visibility of 300m will give a converted RVR value of 600m IF the airport has high intensity approach lights AND it is night. The reason being that the lights will shine through the cloud better in the dark. Although most airports with HIAL’s will mos
Minimum vis you can convert to RVR
800,below it has to be given !!!!
800 is Also the minima for CAT 1
The difference between vis and RVR comes down to the fact that the runway lighting is taken into account. Essentially vis is what you would see without the bright runway lights. Hence with daylight and no lights, reported met vis = RVR. With HIALS and at night when your staring down the runway the distance that you will actually see is approximately twice that of someone looking down an unlit runway.
Ceiling is only a factor at the planning stage when you are looking at the requirements for your destination and alternates, and then, only if the available approaches are non precision or circling. Once your airborne only the RVR is limiting.
Eu ops reference: “An operator must ensure that a meteorological visibility to RVR/CMV conversion is not used for takeoff, for cal-culating any other required RVR minimum less than 800 m, or when reported RVR is availabl
RVR not available, Vis is below 800m: cannot start the approach.
RVR not available vis is 800m, night, HIALS, then CMV=800 x 2 = 1600m: you can start the approach.
