Lifted from a Wikipedia where it quotes Henshaw flight testing Spitfires

After a thorough pre-flight check I would take off and, once at circuit height, I would trim the aircraft and try to get her to fly straight and level with hands off the stick … Once the trim was satisfactory I would take the Spitfire up in a full-throttle climb at 2,850 rpm to the rated altitude of one or both supercharger blowers. Then I would make a careful check of the power output from the engine, calibrated for height and temperature … If all appeared satisfactory I would then put her into a dive at full power and 3,000 rpm, and trim her to fly hands and feet off at 460 mph IAS

Thank you. A fascinating obit, which also has led me to look up B29s in RAF service.

Welcome back.

We’re missing one wingman. Hope Mark12 reappears from his sortie.

In light of pending news, lets take a little sabbatical. Things are getting silly and I cannot so how further contributions are helping. I’ve opted to lock this thread temporarily until Richard can get back to us all with an update. Thanks a great deal for being so understanding and nice to the moderating team. It’s been lovely to come back and see this happen.

Please don’t force us into removing pointless posts that are failing to contribute to the thread subject, or consider locking it entirely if it spirals out of control. You’ve all been very good to us mods and that’s heartening 🙂

When has the inside of a military aircraft ever been ergonomic? Those struts are an archtitectural nudge at what lies inside 😉
