The division into three different ceilings I've never seen before and I am likely to think it's just different words for the same thing, but I really don't know. If they are different I have a guess on how the difference may be: <br />Most new fighters are capable of climbing above 50.000', but that altitude is set as the combat ceiling because the pilot doesn't wear a pressure suit, and if he lost his cabinpressure he would be in trouble. So maybe absolute ceiling is the max the aircraft could fly disregarding pilot safety. <br /> <br />Internal fuel is the amount of fuel you can have within your aircraft. A lot of times aircraft will carry external tanks aswell. <br /> <br />I haven't heard the term Standard fuel. <br /> <br />Regards RUNhttp://www.jets.dk/cs/forums/thread/855.aspxMon, 20 Sep 1999 18:23:00 GMTa23efcf1-9e75-4ff9-be18-cd9cb68b9485:855Anonymous0http://www.jets.dk/cs/forums/thread/855.aspxhttp://www.jets.dk/cs/forums/commentrss.aspx?SectionID=15&PostID=855*** Posted by Zvi Kreisler *** <br />Questions: <br />1) what are the definitions of: <br />Service Ceiling, Combat Ceiling, Absolute Celing of a fighter a/c ? <br />2)The same for: <br />Internal fuel, standard fuel. <br /> <br />thanks for your answers <br />Zvika
