NO SIR.You wont get TR#1.Both TL's must be idle to get TR.They wont get GS either(gear not tilted,TL's idle).Crucially,this leaves the GA option.And theres your big difference.The plane wont dig a big hole for you and your 200 passengers.
I don't know where you found your info.
Excerpts from the 777 system description manual :
A. Thrust reversers.
...
Reverse thrust is only available on ground. The R/T levers can be raised on;ly when the forward T/L is at the IDLE position.
The EEC inhibits reverser isolation valve actuation and reverser deployment unless the aircraft is on GRD with the engine running...
Note the singular mode.
B.Speedbrakes
...
In the ARMED position, the speedbrake lever is driven aft to the UP position when :
-Landing gear fully on the ground (not tilted)
-T/Ls at IDLE.
On the ground, when either reverse T/L is moved to the reverse idle detent, the speedbrakes automatically extend. The speedbrake lever does not need to be in the ARMED position...
Did I read correctly ?
Or is there a misunderstanding on the definition of a tilt ?
