What are the shortcomings of using an angle of incidence indicator for feedback sensor?(a) Damage from bird strikes and local airflow disturbance(b) Damage from ice formation and local airflow disturbance(c) Ground and impact damage from landing(d) Works only in subsonic rangesThis question was addressed to me in homework.I need to ask this question from Control Laws in FBW topic in chapter Fly by Wire Flight Control of Avionics

Answer»

Right option is (a) Damage from bird strikes and local airflow disturbance

Explanation: Although the angle of incidence indicator can provide motion feedback sensor information the major shortcomings of using them are damage from bird STRIKE as they are mounted EXTERNAL to an aircraft and effect of the local airflow AROUND the fuselage cause variations in MEASURED values.
