A paper by James George of the Civil Aeronautics Administration entitled “Development of Stall Warning Indicators”, covered three distinct types of stall warning devices. Two of these instruments will be commercially available in the near future. These will function successfully under all flight conditions except when ice has accumulated on the wings, and are considered suitable for use on private‐owner type aircraft since such aircraft are seldom involved in stall accidents where ice is a factor. The continuing programme involves the development of the third device suitable for use on existing air‐carrier type aircraft which will obtain an adequate Warning margin even when the wings are “iced up”. The results of wind tunnel and flight tests involving all three devices are presented and the entire problem is discussed in detail.
