Metric Conversion to IMPERIAL

If you are importing a glider into the UK it may well have metric instruments. Or if you have second hand metric instruments, changing these to imperial need not mean complete replacement. Both Air Speed indicators and Vario’s can be re-faced and converted to read in knots.


We can also change the colour markings for specific glider types and re-issue form 1’s. The only instrument we can’t convert is an altimeter. A metric altimeter typically has one turn for 1000m and an imperial altimeter has 1000 ft per complete turn so it will not convert. The simplest way is a trade in. Navboys will offer you a trade in value against any Winter instrument working or not and with or without a form 1.
