Don't forget that all of the aircraft come with a range of optional max takeoff mass numbers According to JP2003: AC operate A319 at 70,000 kg, A320 75,500 kg, A321 93,000 kg America West A319 70,000 kg, A320 75,500-77,000 kg Frontier A319 64,000 kg Jetblue A320 75,500 kg Northwest A319 64,000 kg, A320 75,500 kg United A319 64,000 kg, A320 73,500 kg US Airways A319 64,000 kg, A320 73,500 kg, A321 93,000 kg Lufthansa A319 68,000 kg, A320 73,500 kg, A321 83,000-89,000 kg Privatair A319/ACJ 64,000-75,500 kg The option chosen will depend on the need for range, performance limitations at the airports used, the options available at the time of order/delivery or by retrofit, standardisation with previous aircraft in the fleet, differences in operating costs due to higher weights (airport and navigation charges, maintenance) and prices charged by the manufacturer. Published (advertised) max range is usually at the highest available take-off mass option, often for a light aircraft (low number of seats and galleys) and is generally passenger payload only. Fuel reserves may be lower than most airlines use and often there are no allowances for en route winds or variations from the great circle track. Speeds may also be unrealistic for a practical operation. Comparisons by Airbus for different A320 family aircraft are probably reasonably fair (except for the cargo omission) and the same would be the case for Boeing data for 737NGs. I have a May 2003 Airbus brochure which gives for first/economy layout A319 124 seats 3,700 nm, 6,850 km A320 150 seats 3,000 nm, 5,600 km A321 185 seats 3,000 nm, 5,600 km Antoin Daltun ----- Original Message ----- From: "Bahadir Acuner" <bahadiracuner@xxxxxxxxx> To: <AIRLINE@xxxxxxxxxxxxxxxxx> Sent: 13 August 2003 15:02 Subject: Re: Right Plane, Right Routes > If that's the case for an A320 on YYZ-YVR route how is it on an A321 on the > YUL-YVR > non-stop? :) I know A321 has got shorter legs, or am I just wrong? :) > > BAHA
