Chapter 549 - Amateur-Built Aircraft - 549.109 Minimum Rated Engine Power

(a) Piston engines: To ensure that there is a reasonable expectation of meeting the climb test requirements set out in section 549.111, the minimum permissible rated engine power shall be determined by the following equation:

where

 

P_min = rated power of the engine(s) in kw (BHP);

 

b = wing span in metres (ft);

 

M (W) = declared maximum T.O. mass in kg (weight in lb);

 

C = 0.01339 (for use with fps units = 0.018) for monoplanes (including tandem wing and canard aeroplanes); or

 

C = 0.01711 (for use with fps units = 0.023) for biplanes or triplanes.

(b) Turbine engines: The minimum permissible rated power/thrust will be evaluated on an individual basis.
