Autoland Boeing - Aircraft Dispatch Requirements?
 

Crew Qualitifications / LVP's, Airport Services, etc. aside.

What are the legal Dispatching Requirement/s as far as Boeing is concerned for the aircraft to be used by the Crew (in this case on the 737) for example to perform a DUAL CHANNEL A/P (ILS) Approach right through the Flare and Roll-out?

Is a Placard in the Cockpit required stating CAT II or CAT III APPROVED?

Is a specific Techlog Entry/Release or in the Aircraft Cockpit Manuals a specific reference required?

Thanks in advance.

Normally just a placard 'CatIII Autoland' or similar (assuming the a/c state matches, of course, and someone hasn't just bought a placard on EBay)

err - it is in some airlines, and a GOOD IDEA it is too with short turn-rounds and no engineering support! Idea behind it is that the Tech Log entry 'Downgraded Cat I' can easily disappear behind 5 or 6 sheets.and it is far simpler and easier to see than any ADD as well.

If you are flying a 737 with auto-rollout just press the autoland status recall button once the IRS's are aligned and if it comes up empty you are good for LAND 3. If it come up as NO LAND 3 you still can do a normal autoland in LAND 2 configuration (fail passive) which still allows CAT III operation including automatic rollout, only if it says NO AUTOLAND you cannot do that.

That said on planes without those neat status messages on the upper DU we still get a placard installed from maintenance if the plane has a degraded autoflight system stating CAT II or CAT I only, if no placard is present normal operation, e.g. CAT III, is possible.

Boeing does not make the legal requirements; your regulatory agency does. How your airline implements those regulations is set out in your Flight Operations Manual and Aircraft Operating Manual (or whatever they are called in your airline).

The requirements for a Cat I or II or III Autoland will be in those documents. You may have to look at both of them as well as the DDG/MEL to get the complete answer.

In my airline the cockpit placard is controlling for Cat II or III approaches. The Aircraft Log and DDG (along with any handy reference charts that may be in the other manuals) will tell whether a Cat I Autoland is allowed.
