Spit IIA Speed in game test

[Crumpp]

Even if he had set field elevation, typically 995mb, thats only about 150 feet/50m difference from the default 1000mb. 992 would be about 240ft/80m.

It should be easy to confirm the atmospheric model.

1. Go to a known airport like London Biggen Hill. The field elevation at EGKB is 599 ft.

2. Set your altimeter to field elevation (599 ft) and your altimeter setting should read 992mb when converted. If it does not read the setting and record the temperature.
