As I said, 30 years since, but my recollection from F-27 days was that, on landing, the throttles were lifted, removing the Flight Fine Stop, and allowing the props to go to Ground Fine. One airline, and one airfield (no names, no pack-drill) rejected a take-off at low speed, and the captain merely drought the throttles back. The Flight Fine had engaged, and very soon the TGT began to rise, doing the engine a severe mischief. I would suspect the same on the Tyne. Of course, after this length of time, and an ageing brain, I could be spouting a load of old rubbish.
