...We know the wx conditions, the length of the runway (7771') Hypothetically, let's assume the a/c weight was 150,000# and the approach speed was 145kts. Touchdown at the 1,000' mark, speed brakes deploy one second after touch down, reversers fully deploy and are effective 3-4 seconds later, followed by max brake/anti-skid. Touchdown speed of 145kts, plus 16kts tailwind component which is 161kts which is 185mph. In the 5 seconds after touchdown the a/c has traveled approximately 1355'. Total r/w length is 7771' minus touchdown 1,000', minus 1355'runout leaves 5416' of usable (?) r/w remaining. Now add the tailwind component of 16kt, and the wet r/w penalty of 30%. Not much margin for error to remain, FEET DRY. PPP=PPP
