Answer:
a) 3.18 degree.
Step-by-step explanation:
tan Ф = v sinα /( u + v cos α )
v is velocity of the air , u is velocity of pilot , α is angle between u and v and Ф is drift angle of the pilot
tan Ф = 18 sin ( 290 - 224) / 300 + 18 cos ( 290 - 224 )
= 18 sin 66 / ( 300 + 18 cos 66)
= 18 x .91 / (300 + 18 x .40)
= 16.38 / 305.4 = .0536
Ф = 3 .18 degree.
