Re: Can the A321XLR make it LHR-HLE direct?

The main problem would be the lack of runway length though. B737-800 already have problems land there, let alone the A321XLR. an unconnected statement. ISA MSL data: The XLR will have about the same MLW that the regular A321 sports ~79..80t for ISA and sealevel that is 1780m landing field length. T...
