A Flight Investigation of the Meteorological Conditions Conductive to the Formation of Ice on Airplanes


Book Description

Data from flight measurements of the meteorological factors related to the intensity of icing conditions are presented. The physical factors that establish the distribution of liquid water in clouds of various types are discussed and the results of the analysis are used to formulate certain rules for the forecasting of icing intensity. The problems of determining the range of values of the significant factors defining icing intensity for the purpose of the design of ice-protection equipment are discussed and tentative values are given.

Notes on the Stalling of Vertical Tail Surfaces and on Fin Design


Book Description

It may be concluded that the stalling of vertical tail surfaces is not in itself a dangerous condition. Provided sufficient directional stability exists at large angles of sideslip, the tail stall may occur with modern airplanes, as with those of the past, without the knowledge of or concern to the pilot.
