A method is presented for the determination of slipstream effects on static longitudinal stability and control of multi-engined propeller aircraft. The method is partly based on elementary momentum considerations partly on a correlation of windtunnel data. The method allows the determination of: The increase in lift due to propeller slipstreams, The change in tail-off pitching moment, both with flaps retracted and deflected. The location of the propeller slipstream relative to horizontal tailplane and the associated effect on average dynamic pressure at the tailplane. The change in average downwash angle due to slipstream at the tailplane.
