"Gross" and "net" planned runway length for the Haifa airport
Gross and net are not aviation terms for runways. Many runways have extra space on either end to be used as stopways, giving extra stopping distance in case of an overrun.



I'm going to hazard a guess and say that the gross length is the total paved area of the runway and the net length is between the thresholds that is usable for takeoffs and landings.
