It puts this thread to bed.

Isn't it telling us that the manuals are wrong?

The answer is in the BMM / SSM (but probably not in the Ops manual), it is just not all in one place.
It is as simple as 2+2 = √4 squared

By taking snippets from many separate chapters & piecing bits together I came up with the conclusion in post 16,

Quote:

During LAND the A/T is in SPD mode until 30ft when it enters flare IDLE mode and becomes dormant. G/A ARM mode is enabled awaiting a TOGA input to go into G/A ENG mode. If TOGA is initiated (AIR or GND) and flaps are still deployed T/L will advance.

Sorry, but I disagree. The pilots' operations manuals specifically say that after restowing the reversers plus a specific time period, the A/T will become available for TO.

Also, I'm sure I've already read in a manual, somewhere, that the A/T is inhibited with any reverser lever deployed.

All times are GMT. The time now is 15:12.
