However, with no room to navigate up the steep glacial valley, the pilots finessed the airplane over the hurdle with no more than 200 ft of clearance. In addition, decreased air density also decreases ram air pressure, meaning a indicated airspeed from a pressure-based airspeed indicator will read lower than the true airspeed.

For example, if we were to takeoff on an airfield at sea level at 0C (32F), it would take 1520ft to reach our obstacle clearance height of 50ft. Whereas for the same airfield on a different day, if it were 30C (86F), that same obstacle clearance height would take 1880ft. That’s an extra 360ft!
