CPL Flight test - 15% factos
hews16 created the topic: CPL Flight test - 15% factos
During the ground component of a flight test, I was told by testing officer that 15% factor is added for each unknown component on the take off charts. E.g The scenario was: if wind info not available, surface is soaked long wet grass (and your take off chart has no window for surface), slope goes down but you don't now by how much, then "how would you account for this in your calculations?"
His response in the end was that 15% x 3 (for the 3 unknown factors of wind, surface, slope will be the factor amoutn. Not just one 15% as normal.
I've looked everywhere for a legal reference. Is anyone aware of this? thanks
That being said, I see no legal reference for an Australian aircraft. I did find an old draft AC (dated 2003) at
. This document lists some correction factors on pages 20 and 21 respectively.

The use of fudge factors in certification and operational requirements has a long and illustrious history. 15%, certainly, figures in a number of takeoff and landing requirements. However, the present testing officer's global waffle should be noted to be just that, I fear.
An educational session at the bar definitely is called for.
