Been in and out of 600M at 4110KG (increased MTOW STC) @ 38C, 95% Humidity, and 100 AMSL, 5knt Tailwind component.
was a eye opening experience, as there was a large cliff at the end of the runway. Stall warning stays on for a bit and it tends to waffle.
700M is a pretty good standard to aim for. you'll get it up and away under most conditions at that length.
