I am not (yet) rated on the A320...

Volume:
Could anybody enlighten me, whether the flight spoilers are available during any phase of the flight, even close to the ground with the flight controls being in flare law, at all flap settings, with U/C down?
Flight spoilers are always available via manual control unless any of the following is true:

>>REV SEC 1 & 3 fault**
Elevator Fault
Alpha or AOA protection active
Full flaps set
TLs are greater than MCT

** Revised

Flight spoilers (speedbrake function) are controlled via the SEC (Spoiler/Elevator Computer) #1 & 3. The #1 & 3 SEC control Spoilers 1-4. Speedbrake function uses panels 2,3 & 4.


Max deflection (in degrees) of flight spoilers:

Spoiler-----Autoflight--------------Manual Flight
#3 #4............25...............................40
#2...............17.5 (12.5 Config 3).........20


Max deflection of ground spoilers is 50 degrees unless partial lift function is called then it is 10. (see earlier posts on this) Ground spoilers (#1-5) are actuated via SEC 1,2 & 3.

Will there be an auto spoiler function (armed spoilers, lever pulled) if one T/R is inop on the A320?
Ground spoilers will activate despite having a T/R inop. Please see earlier posts for more on this.


Papagaio:
as you touch-down and you see NO ground spoilers deploying, in that case a go-around could be initiated because you've got eng-2 (rev pinned) ready to go and lots of speed (even if you got eng-1 retracting the shells you'll be up to flight speed in a second or two)
Please see earlier posts on this. Once the T/Rs are deployed, one is earthbound unless you have a surplus of runway ahead. This is the case with most civilian jet aircraft.
