Adding MZFW to aircraft weight calculations
Currently, game calculations do not take into account an aircraft's maximum zero fuel weight (MZFW) which is the maximum an aircraft can weigh in operating configuration with payload. Because of this, there is a slight disparity between calculated max payload range and known capabilities in the real world. This is most apparent on planes where the ratio between MTOW and OEW is closest to 1. MZFW can easily be found in aircraft fact sheets provided by manufacturers, and it is suggested that an additional calculation be added to flights to enhance realism.
Change would provide more realistic operation capability to planes that rely on thin margins for payload and weight, such as turboprops and small jets.
