## AWO.C.TOO.109 CS AWO.C.TOO.109 Guidance system

\- (a) The take-off guidance system shall be such that the display of incorrect guidance information to the pilot during the take-off run is assessed as remote. In demonstrating compliance with this criterion account need only be taken of incorrect guidance of such magnitude that it would lead to the aeroplane deviating from the runway, if it is followed.

\- (b) The probability of loss of take-off guidance during the take-off shall be assessed as remote.
