As you probably know, the change to Celsius was made in 1996. >Same goes for the airshow, moving map display with altitude >temperature and distance on it. This is a bought in product. What you see on any particular aircraft depends on the product they use. Sometimes the same airline will have two different products in operation. The design and customisation will almost certainly be done by the manufacturer. You may wish to target your complaint on the basis that the airline staff probably do not even think about this issue but once aware of it, may be able to request a change. >>visibility in yards and statute(!) miles No. US civil aviation visibility is in *feet* and statute miles. US military TAF visibility is in metres. UK aviation previously used yards and 'miles' for visibility. Some people claim that the 'miles' were nautical. This demonstrates two other features of the non-metric world: 1. The US and UK frequently have different non-metric measures for the same thing. 2. US culture appears more comfortable with feet than yards. UK culture appears more comfortable with yards than feet. The UK therefore has an easier transition to metres than the US. People say that UK aviation converted to metres for visibility in the 1960's or 1970's. Somebody claims January 1967 was the date of the transition but I have no evidence for that. This accident description confirms the UK use of yards and 'miles' in 6 May 1962: http://www.farvis.com/ventnor2.htm This official accident report confirms the UK use of metres in 22 August 1985: http://www.aaib.dft.gov.uk/formal/gbgjl/gbgjl.htm
