The ranges above are based on an approximate average burn rate of 50 litres per hour of flight at 200km/h i.e.
Cruise I. Monitor the fuel burn rate of your particular aircraft against these figures (it may be more or slightly less)
and always err on the side of caution. Also note the additional ground run and roll distances based on take-off
weight, fuel load, C of G, runway slope, icing conditions etc. Never conduct flights purely based on the figures stated
above.
