ANGLE OF ELEVATION AND DEPRESSION
answer carefully the picture bellow
8. A pilot is traveling at height of 35,000 feet above ground.according to her GOS, she is 40 miles away from the airport runway, as measured along the ground. At what angle of depression will she need to look down to spot the runway ahead?

Question:A pilot is traveling at height of 35,000 feet above ground.according to her GOS, she is 40 miles away from the airport runway, as measured along the ground. At what angle of depression will she need to look down to spot the runway ahead?
Answer:
Before we answer it lets change 35,000 ft to miles
1 foot is equal to 0.000189393939 miles
35000x 0.000189393939 = 6.6
SOH CAH TOA
since we need to find the angle of depression using adjacent and opposite we use tangent.
Tan = opp/adj
tan = 6.6/40
6.6/40 = 0.165
Using inverse tangent
Tan-¹(0.165)
= 9.36
Since we need to find the angle it's
= 9°
