If an airplane glides at an angle of attack of 10°, approximately how much altitude will it lose in 1 mile?

To determine how much altitude an airplane will lose while gliding at an angle of attack of 10° over a distance of 1 mile, we can use basic trigonometry. The glide path can be visualized as a right triangle, where the glide distance is the hypotenuse and the altitude lost is the opposite side to the angle of attack.

When gliding at an angle of attack of 10°, we can calculate the altitude loss using the tangent function. The tangent of the angle (tan(10°)) can be used to find the ratio of altitude loss to horizontal distance. Over a mile, which is 5280 feet, the vertical drop can be calculated.

The formula we would use is:

Altitude drop = Distance * tan(Angle)

Plugging in the numbers:

• Distance for 1 mile is 5280 feet.

• tan(10°) is approximately 0.1763.

So, the altitude drop becomes:

Altitude drop = 5280 feet * tan(10°) ≈ 5280 feet * 0.1763 ≈ 930 feet.

Given that we need a practical approximation, this rounds close to 960 feet, which aligns with one of the choices provided. However
