GATE Aerospace 2022 Q45: Euler Angles, Angle of Attack, Sideslip in Straight & Level Flight

Aerospace Engineering > GATE 2022 > Aircraft Orientation

For a conventional airplane in straight, level, constant velocity flight condition, which of the following condition(s) is/are possible on Euler angles (φ, θ, ψ), angle of attack (α) and the sideslip angle (β)?

φ = 0°, θ = 2°, ψ = 0°, α = 2°, β = 0°

φ = 5°, θ = 0°, ψ = 0°, α = 2°, β = 0°

φ = 0°, θ = 3°, ψ = 0°, α = 3°, β = 5°

φ = 0°, θ = 5°, ψ = 0°, α = 2°, β = 5°

Correct : a
