(c) AOA computation The A/C is wired in the AOA unique selection, so the ADR computes the AOA with the reading of one resolver. The second resolver is used as a back-up. The monitoring function is descibed in 34-18. The ADR determines the corrected angle of attack value which depends on the system number and the slat/flap position. For a CAS less than 60 kts: AOAc = 0 and status matrix is coded NCD. For a CAS more than or equal to 60 kts, the corrected angle of attack is calculated as follows: AOA ind AOAc = ------- + I K where: AOA ind = Indicated Angle of Attack (Ref. 34-11-00 for the relation between resolver and AOA indication) K, I = Correction coefficients which depend on system number, slat and flap configuration and magnitude AOA indication. The configuration is defined by the status of four input discretes (Ref. 2.A.(2)(c)). The results of the above computation is available on the labels: - label 221 = Indicated Angle of Attack - label 241 = Corrected Angle of Attack
