J31 Runway Performance
Hi, I'm wondering if anyone here can help me with J.31 runway performance. What kind of payload can a J.31 take out of the following runway conditions:
3600 feet runway length, sea level airport, ISA+5, no wind, no climb gradient required, fuel for1 hour stage length plus IFR reserves
Also how much payload can the aircraft land with under the same runway conditions but landing with fuel for 1 hour stage length fuel plus reserves. Does a wet runway versus a dry runway affect the payload much?
I'd appreciate any help I can get with this. Thanks!

You'd need the bae performance app for exact figures, but will a rough calc you should be able to take off to mtow with a 32. Water meth / Apr will make a difference.
I can get exact figures for a 32 if you need.

Thats 1100 meters.
Plymouth in the UK is 1160 meters and with a 30min trip with IFR reserves etc it was limited to 8 blokes with 10kg of baggage. Every +5 above ISA you drop a pax. APR and water meth won't help until your above ISA +5 because you will be torque limited.
Also as well its very airframe dependent how heavy it is.
