Final answer:
The integer that describes the plane's location during flight is 38,000 feet above sea level.
Step-by-step explanation:
The integer that describes the plane's location during flight is 38,000 feet above sea level. When an airplane is flying, its position is measured by its altitude, which is the height above a specific reference point, in this case, sea level. Therefore, the integer that represents the plane's location is 38,000.
The integer that describes an airplane's location during flight when it flies at 38,000 ft above sea level is 38,000. This integer is used because altitude above sea level is typically measured in feet and is represented as a positive number when above sea level. The altitude is a crucial element in air traffic control. Air traffic controllers must know the altitudes of all aircraft to ensure that they maintain safe distances from each other, following the regulations set by the Federal Aviation Administration.
