682........As a visiting(summer season)320 crew dept off 32 was 'limited' to the eng/out climb gradient and obstacles(royalty pub)as one turned to aheading of 020..Off 14 the next obstacle was the Alps,so one occasionally took off with a 10k tailwind,increase flap,to move the load.
As JT says regs require that half the distance from VR to the 'screen' height must be over runway-which makes one wonder how high one actually is,over the end of the runway, to meet the 15'screen'at the end of the 'clearway'??
