The ventilation started once we were in flight. It's not clear to me if it needs the plane to move, or if it was fixed during the 2 hours we were stuck on the ground. By the way, the flight itself is less than 2 hours. The wait in the plane, grounded, was more than the flight time.

I think the Air conditioning is powered by the APU (gas turbine in the tail of the aircraft) on the ground or Fixed Electric Ground Power. Inoperative APU is not safety critical so airlines are allowed to fly with this defect. I'm guessing you weren't connected to ground power because Ryanair save money by only buying the absolute minimal services from the Airport; the FEGP is usually part of the air bridge structure in modern terminals but Ryanair flights seem to mostly board up stairs even when an air bridge is available.

> The ventilation started once we were in flight I think how the A/C on an airliner is driven depends the location. There are the engines while in flight, the APU (Auxillary Power Unit, a small jet engine that starts the main engines, tops the batteries, and other tasks) while idling on the ground, off the batteries, or off a service cart on the ground. Running the engines burns fuel, the APU burns fuel, and having the service cart incurs ground fees. So it's likely that RyanAir didn't want to spend to keep the A/C going.

  >>> So it's likely that RyanAir didn't want to spend to keep the A/C going. No, it's not that they are cheap. The pilot warned on the speakers that the air conditioning has broken down. I recall when we boarded, the plane was much warmer than any plane I've ever been. I don't think it could get that warm in the time it take to disembark and reembark, so it probably broke during the last trip.
