Hello,

 

Just a small quesiton related to a project for my University.

 

I found on several forums the decelleration rate in 'RTO' mode for a B744 is 11 ft/s^2. Well, that might be true but I need a valid source like the AMM (Aircraft Maintenance Manual), or FCOM (Flight Crew Operations Manual) or a QRH (Quick Reference Handbook) or anything else.

 

Question: Anybody knows a valid source with the maximum decelleration rate for the B744 when the Autobrake Selector is set to 'RTO'?

Note: PMDG source not allowed. (My apologize dear PMDG, nothing against your knownledge because I know it's 99% true, but we need a 'real valid' source).

 

Thanks in advantage!

Now I may be completely wrong on this, but I believe the Rejected Take Off value is the same as Max Auto... If there is an aircraft manual you can find, I would look up that value.

Rejected Take Off value is the same as Max Auto

 

I think that any setting other than RTO is determined by deceleration force. RTO on the other hand, I think, is just enough to keep the tires from blowing.

According to the relevant manual, there is no deceleration level computation for the RTO setting and full hydraulic system pressure is applied. The max available pressure for both MAX AUTO and RTO is 3000 psi, but the deceleration is set at 11 ft/s^2 for MAX AUTO.

 

HTH

I don't have a B744 FCOM and I haven't checked where it is for other Boeing types, but I would start my search in FCOM Vol. 2 Landing Gear.

Oke, did a new search in the AMM and found a table. Shame I did not found it once. Thanks all.
