CS 23.2305 Landing gear systems

(a)The landing gear is designed to:

(1)provide stable support and control to the aeroplane during surface operation; and

(2)account for likely system failures and likely operation environment (including anticipated limitation exceedances and emergency procedures).

(b)Aeroplanes must have a reliable means of stopping the aeroplane with sufficient kinetic energy absorption to account for landing. Aeroplanes that are required to demonstrate aborted take-off capability must account for this additional kinetic energy.

(c)For aeroplanes that have a system that actuates the landing gear, there is:

(1)a positive means to keep the landing gear in the landing position; and

(2)an alternative means available to bring the landing gear in the landing position when a non-deployed system position would be a hazard.
