@AviatorInsight - is this likely to be an issue ?
Thanks for the shoutout Flydoc.
Unfortunately yes it will be even more of an issue on this route than a regular east coast flight. Here’s what a quick look at the numbers shows.
Maximum take off weight for the 737-800 = 79 tonnes
Maximum take off weight for the 737-700 = 70 tonnes
Conditions: 20°c, Dry runway, No wind, Packs to AUTO.
Calculations (-800) for Runway 14R shows a MTOW of 70.8T.
Runway 32L shows a MTOW of 70.5T. (More limiting due to terrain clearance to the north).
Calculations (-700) Runway 14R shows a MTOW of 66.0T.
Runway 32L shows a MTOW of 65.3T.
As soon as there’s any kind of tailwind, all those figures drop dramatically.
As a last resort at trying to increase the TOW we can use the APU to supply air for air conditioning, that could get us an extra 0.7T if we were extremely limited.
Eastbound could also prove to be difficult in the winter months if adverse weather is forecast. Usually if LST has adverse weather then it’s a similar story at both HBA and MEL.
This will mean additional fuel will need to be uplifted ex PER so pax/bags/cargo numbers would have to be decreased to be below the maximum landing weight on arrival.
