I am not a fan of the 30 hour taf.Nothing civil stays airborne that long so why do we need a forecast of this duration which is frequently amended during its period of validity?
My principal flying is from Crawley to the eastern Med and the Red Sea coast of Egypt.The taf can have changed a number of times by the time I am starting on the return sector and be markedly different from the Met Office's first guess of the day.In these days of trying to save our company's money the forecast can have a marked difference on the fuel uplifted down route and the penalty of flying these reserves back to the UK for 6 hours.
