How many decimal places please.
Would be grateful if you could advise me how many decimal places are used when flight crew are putting in "the numbers" into the flight computer..some call this the flight management system. In particular I am interested in the fuel amount in weights...strictly termed, the mass of fuel. Will it accept litres also, and is there a "conversion button" to quickly skip from metric to non metric..viz pounds weight? Or U.S. gallons volume to UK gallons volume?
