In some Flight Manual I noticed, that helicopters (like the EC120 or Lama) climb better in higher altitudes than at sea level:
at 2000ft ISA: 600ft/min
at 3000ft ISA: 700ft/min
I expected contrary because of the decreasing density. Maybe an aerodynamic reason....?
Does someone know the answer?
Thanks for answering!:ok:
