Stupid question – altimeters.
If this is a stupid question, please ignore and put it down to the fact that I’m at home ill and also suffering from severe flying withdrawal (4 weeks damn it!)
I was contemplating the instrument panel of the trusty 172 that I fly and my gaze was drawn to the altimeter, in particular the little Kollsmann (sp?) window.
Here in the great white north (and the US presumably) it is calibrated in inches of mercury (because metric would be far too easy!). I have heard rumours that the UK uses hectopascals (I think these used to be milibars?).
I know that some people fly N reg US planes in the UK, do they have to change out the instrument? Use tippex on the numbers? Or do some funky conversion in their heads? has this ever caused any issues?
Just curious and again If I’ve blatantly missed the point, be nice to me.
