airportable Posted April 2, 2011 Share Posted April 2, 2011 Hi folks. Picked up this intresting item at Hack Green. Apart from the details etched on it, what would it have been used to caculate? I understand from some of the terms on it, it may have been used by the RAF? (Image slightly distorted due to camers angle) Thanks, Andy.

Adrian Barrell Posted April 2, 2011 Share Posted April 2, 2011 It's the British version of the good old E6B, aka wizz wheel. It's just a simple computer, a rotary slide rule in effect used to work out conversions and headings. The front is fairly self explanatary, 'corr oat' means corrected outside air temperature, this, together with pressure altitude is necessary to work out true airspeed. The reverse is used to work out headings to obtain required course allowing for wind. It is missing the sliding wind speed board. Still used today and required for passing ppl nav exam.

NigeP Posted April 3, 2011 Share Posted April 3, 2011 Going back to my Air Cadet Days, wasn't this known as a Dalton Computer? Nige Quote Link to comment Share on other sites More sharing options...
