Why can’t I change my takeoff and landing weight on the runway performance page?

Takeoff and landing weight is directly tied to the takeoff and landing weight on Flights page. If the presented takeoff and landing weight on the runway performance page is not what you desire to use for calculations, you will need to modify your payload and/or fuel load on Flights first, to achieve the desired takeoff and landing weight for runway performance calculations.
