Expected Rate of Climb
Our Bulldog failed its airtest following C of A because it was 140' below expected 900' climb rate. The aircraft manual uses a table with the variables of aircraft weight, altitude and temperature. I have used the data and I get a much lower expected climb rate-nearer 800' expected.
Can anyone help in advising me of the parameters I should be using?
The data for the test was Airfied Altitude 321'AMSL. Temperature 21 C(ISA +6) Pressure climb 1200'-4700 (average alt 2950). Airfield Pressure 1030mb. As far as I am aware the pressure element does not affect the temp I should be using in the manual but what average height should I be using. Thanks
