Winglets Vs Non And 320 Vs 73G/H

Thu Jan 12, 2006 8:27 am

At what point does a winglet-equipped 737-700 or 737-800 outperform, cost-wise, a non-winglet-equipped 737-700 or 737-800? I realise it will probably depend upon the weight of the aircraft at the time and the fuel consumption. Moreoever, how does the 320's 'wee winglets' perform, cost-saving-wise, in relation to the 737-700's or 737-800's winglets?

Cheers.

Winglets provide the most dramatic improvement on long sectors, and an exact figure is hard to come by. One customer, WN, says the winglets provide savings on all routes longer than 40 minutes. Other customers may have a much different break-even point. Winglets also provide an immediate to take-off performance, reducing the take-off roll and increasing payload.

Probably far too early to say.

The new Airbus winglets are still in development and testing.

I meant the current wingtips on the 320.
