6.3 FUEL SAVINGS

 
 
 
 
 
 
 
 
The following table gives examples of the savings possible through the application of correct procedures and practices. The values represent typical saving as there is variation dependant on the actual base case considered. However these figures serve to illustrate the magnitude of savings being achieved (or penalties being paid). The savings are expressed in kg of fuel for one flight, with the sector length being representative for each aircraft.
