EVAC 320
 
Guys,

If the overwing emergency slides in 320 are inflated, do the ground spoilers retract?
(without hydraulics it's very questionable)

There is nothing in the manuals and there is nothing in the flows for speedbrake lever disarming.

Any reference?

No idea if this is relevant to you, but from my experience of looking out the window as a passenger: it looks like there's plenty of space between the fuselage and the innermost spoiler (and the marked egress path doesn't overlap), i.e. I doubt there's any likelihood of interference between slides and spoilers.

The book is not of much help here, true

The ground spoilers retract:
• After landing,
• After a rejected takeoff, when the ground spoilers are disarmed.
• During a touch and go, when at least one thrust lever is advanced above 20 °.

EVAC is a serious issue. Trust the manufacturer. If it was an issue they would asked you to retract.

Vilas if course I trust.

It is a matter of education.

It seems its not an issue. True, there is a lot of space.

On aircraft types which do have problems with clearance, they don't necessarily rely on pilot action. The spoilers are forced down by explosive squibs & actuators electrically triggered by door (or fuselage hatch) opening.
