Pressure Altitude!
Pressure Altitude!
Hi, Just doing some revision,. I wanted to make sure I am accurate with regards to calculating the Pressure altitude at an airfield.
Here goes;
The air field in question is at an altitude of 200 feet. The QNH at that moment and time is 1010hpa.
So,
1013 hpa ISA – 1010hpa = 3hpa
3hpa * 30 feet (30 feet per hpa) = 90 feet.
Airfield elevation @ 200feet + 90 feet = 290.
So the pressure altitude for that airfield is 290 Feet.
Please let me know if I’m right as I want to consolidate this issue.
Thanks a mill in advance!
Troy.
