Gauge and speedbar values are correct 1 ft = 30,48 cm
so that 70m = 7000cm , 7000cm / 30,48cm ~ 229ft

Whew ! Do you have any type of "nursery rhyme" type calculation that's easier to use ? Something like "multiply this by that" to get "whatever" ?

I'd go nuts trying to work that out in me head hock:

PDelaney, not to worry as long as its all sorted out.

You just have me puzzled by your "tarmac" speed :mrgreen:

Next time just post a picture of an engine-off bird.

Take care
