Grammar school oik? Well, at least it wasn't a 'comprehensive' school....

Direct entrant? Not many other options these days.

Diesel car? Old chap, historically diesel was simply not an officer's fuel. But if it's powered by a high performance turbocharged engine, you can always say that the car is turbine powered and simply uses the reciprocating element as a gas generator.... Audi A5 3.0 Tdi quattro, for example. But people will still know....

Helicopters? Someone has to do it, I guess.

A2? Definitely enhances the status and more than compensates for all the above. So mote it be...00

But gas? Gas?? Sorry, but you fell at the final hurdle!

Subjunctive? - that brings back memories of 'Ut and the subjunctive' and other terrors of prep school Latin lessons... I never did understand why Gerundives were considered 'attractive' either. If you didn't have to study such horrors at your school, you were very lucky.

Anyway, back to the dangers of the 'victory roll'....

Usually observed to be a high speed beat-up, balls-out on the deck, followed by a climbing aileron roll. As the aircraft runs in at high speed, it will very likely be trimmed for such speed. Pulling up, it will begin to decelerate. Full aileron and rudder to balance will cause a lot of drag, so it'll decelerate even more. It has now slowed down and the untrimmed state will tend to pitch the aircraft nose down as the roll progresses; the pilot may well pull against this, reducing the apex height accordingly. As the roll reaches the final wings level state, the aircraft will probably be descending and significantly out of trim. In addition, the attitude needed for level flight at the new speed will require a higher pitch angle than did the initial beat up. So the pilot may well need full aft control column to stop the descent and to oppose the out of trim state......and recovery to level flight may well take longer than anticipated, or may not be achieved until terra firma prevents any further descent.


How many of us have seen Bloggs cock-up a barrel roll and bury the nose on exit....?
