In reference to the last two posts:
a) Neither the original EC requirement nor the subsequent UK regulations (
http://www.legislation.gov.uk/uksi/2...0051089_en.pdf) prescribe the format nor content for the insurance certificate. They merely state that if asked by the CAA and owner / operator must supply “an insurance certificate or any other evidence of insurance relating to an aircraft operated by the air carrier or aircraft operator for aviation-specific liability in respect of passengers, baggage, cargo or third parties”. There was an attempt a few years ago to come up with a standard certificate but it was not finalised. Thus it may well be that you need the certificate and the schedule to cover all the bases.
b) The above UK regulations do not state that the proof of insurance need to be in the aircraft, simply that the owner / operator must be able to provide them within a ‘reasonable period’. That said it would probably be a lot less hassle to provide them on demand that to risk the ire of an overly zealous inspector!
Hope this helps.
