An overview of the studies about several ice accretion effects on aircraft flight dynamics was presented here. Special attention was paid to the following areas: the way to obtain the aerodynamic data of iced aircraft

the flight dynamic modeling and simulation of iced aircraft

the effect of ice accretion on the stability and handling quality characteristics as well as the flight performance. Based on the progress of existing research in these areas

some key issues deserving more attention of the researchers for resolution are addressed

including: obtaining the aerodynamic data of iced aircraft through numerical simulation method

consummating the calculation model of effects of ice accretion on aircraft aerodynamic derivatives and enhancing the investigation on stall problems of tailplane. The simulated ice wind tunnel

numerical simulation method

stall of tailplane should be further studied and more test data should be obtained in the future.
