Control tower
Highest point of the landing area
Lowest point of the landing area
None of these
Answer is Right!
Answer is Wrong!
The correct answer is: C. Lowest point of the landing area.
Airport elevation is the reduced level above mean sea level (MSL) of the lowest point of the landing area. This is important because it helps pilots to determine the correct approach angle for landing. If the airport elevation is too high, the pilot will need to approach the runway at a steeper angle in order to avoid landing short. Conversely, if the airport elevation is too low, the pilot will need to approach the runway at a shallower angle in order to avoid landing long.
The control tower is not relevant to the calculation of airport elevation, as it is not located on the landing area. The highest point of the landing area is also not relevant, as it is not the lowest point.
