As the elevation increases, the runway length has to be changed at what rate?
  • a)
    Decreased @ 5% per 300 m rise in elevation above MSL
  • b)
    Increased @7% per 300 m rise in elevation above MSL
  • c)
    Decreased @ 9% per 300 m rise in elevation above MSL
  • d)
    Increased @ 15% per 300 m rise in elevation above MSL
Correct answer is option 'B'. Can you explain this answer?

Explanation:

As the elevation increases, the density of air decreases, which affects the lift generated by the wings of the aircraft. Therefore, to compensate for this decrease in lift, the runway length has to be increased.

The rate at which the runway length has to be increased with the rise in elevation above mean sea level (MSL) is given by the following formula:

Rate of increase in runway length = (Percentage increase in runway length per 300 m rise in elevation above MSL) * (Elevation above MSL/300)

Option 'B' states that the runway length has to be increased at a rate of 7% per 300 m rise in elevation above MSL. This means that for every 300 m increase in elevation above MSL, the runway length has to be increased by 7%.

For example, if the elevation of the airport is 900 m above MSL, the rate of increase in runway length would be:

Rate of increase in runway length = 0.07 * (900/300) = 0.21 or 21%

This means that the runway length has to be increased by 21% for an airport located at an elevation of 900 m above MSL.

Therefore, option 'B' is the correct answer.
