INDICATOR A Fail-Safe Instrument By Terrencc O'Neill(EAA 5572)
This air-angle indicator was first offered
to EAA members in a July,
1970 SPORT AVIATION article by Terrence O'Neill, EAA #5572, and later in CUSTOM AIRCRAFT BUILDING TIPS, Volume 2 (no longer available). It is a simple, useful instrument for homebuilts and ultralights that will provide information important to the operators of these craft. The use of such a device could have a positive effect on their safe operation. KOST AJWOIt-S
Statistics illustrate the stalls are the cause of a large percentage of aircraft accidents. The common myth is that stalls are the result of flying too slowly. The stall speed prominently displayed on the airspeed indicator doesn't tell the whole story, because an airfoil doesn't stall at a given speed . . . it stalls at a specific angle of attack. Common stall warnings only indicate you are between five and zero degrees of the angle of attack that will result in a stall. THE AIRCRAFT TECHNICAL DICTIONARY defines angle of attack as: "The acute angle formed between the relative wind striking an airfoil and the zero lift line of the airfoil. The chord line of the airfoil is often substituted for the zero-lift line." This relative wind cannot be directly observed, so a device such as this air-angle indicator is needed to show the relationship between the attitude of your airplane and the angle at which the air is flowing over its wings. • inimra rod or tube.
