ASI

If there is no legend on the dial of an ASI, is it possible to determine whether it is calibrated in knots or mph?

Have you tried changing to the "Mini Panel" (W Key) to compare the reading on both instruments?

The Mini-Panel ASI will most likely be reading; "knots".

Press Shift + Z. The IAS is shown in knots at the top of the screen.

Thank you Hagar.      I should have known that.

It's easy to forget these things.

[color=#000000]It wasn't checked Paul. I just figured something was going on with the server or YaBB.

[quote][color=#000000]And I get meters/metres, rods and poles, but what the heck do fish (Perches) and chains have to do with it?

The (Gunter's) chain used to be an important item of surveying equipment. It's an actual chain 22 yards in length. They have one on display at the Weald & Downland Museum at Singleton which is a few miles from where I'm sitting.

Don't think you'd need to look in a museum - as a (now retired) Chartered Surveyor, it would still be my preferred method of measurement. If only because it's a damn sight lighter than most of the alternatives (like the 100-foot Engineers Chain)!

Maybe off-topic, but it was a brilliant (1620) invention, and is so far the only entirely-successful application of the 'decimalisation' principle (that is, the principle of using measurements divisible by ten) that has yet been devised.

It was basically a chain 66 feet (22 yards) long, divided into 100 links.

Thing is, British (and American) property is still measured in yards, translated into acres and furlongs. It's a nuisance, though, that these are measured in feet and yards, and those are usually based on 12, not 10. Gunter, way back then, solved that problem by making his chain 22 yards long - which meant that 10 chains made a furlong, 8 furlongs made a statute mile, and - probably most important - 10 SQUARE chains made an acre........

So - Gunter produced the only sensible 'metric system' that has ever been invented - 'metricating' the Imperial system of measurement.

Of course, the French then produced the current, nonsensical, Metric System, which has left all of us drowning in a sea of decimal points; as one example, an acre is (approximately
