What is the total flying time from 6,500 ft to an airport at 700 ft?

To determine the total flying time from 6,500 feet to an airport at 700 feet, we first need to calculate the altitude difference and the rate of descent. The altitude difference is 6,500 - 700 = 5,800 feet.

For a typical descent, small general aviation aircraft often follow a standard rule of thumb for descent rates. A common descent rate is about 1,000 feet per minute for an aircraft to transition safely from cruise altitude to landing approach.

Using this rate, we can calculate the time it would take to descend 5,800 feet:

5,800 feet ÷ 1,000 feet/minute = 5.8 minutes.

In aviation, it’s common to round up the total descent time to allow for situational factors, airspeed variations, and any additional time required for adjustments. Hence, the total flying time from this calculated descent would realistically be longer due to these considerations.

When we look at the provided options and round appropriately, 10 minutes becomes a reasonable estimate as it factors in that descent variation and the need to level off, adjust, and approach the airport properly, leading to this answer.
