2. Airport Classification
Letters and numerical codes and descriptors have been adopted
to classify airports.
For design purposes, airports are classified based on the aircraft
they accommodate. (Critical Aircraft)
Two classification agencies
1. FAA Classification (Federal Aviation Administration)
2. ICAO Classification (International Civil Aviation
Organization)

3. FAA Classification
Approach speed is the speed at which an aircraft travels while it is on the final
straight to land on a runway.
Most aircraft are generally certified for approach speeds that are within 30% of
the speed at which the wings no longer generate lift (Stall Speed)

4. FAA Classification

5. FAA Classification
As an example, an aircraft designed to accommodate the Boeing 767-200
which has an approach speed of 130 kn and a wing span of 156ft.

11. Critical Aircraft

12. Basic runway length

13. Runway length Correction

14. Elevation Correction

15. Temperature Correction

16. Airport Reference Temperature

17. Airport Reference Temperature

18. Airport Reference Temperature

19. Correction for temperature

20. Check for the total correction for the
elevation plus temperature

21. Correction for Gradient

22. Correction for Gradient

23. Runway Length Correction Example
Compute the airport reference temperature if the monthly mean of
average daily temperature of the hottest month is 27.3 ºC and
monthly mean of maximum daily temperature for the same month
is 43.2 ºC.

24. Work Example
If the airport is located at mean sea level (MSL), and the airport
reference temperature is that calculated in Problem 1. Apply
temperature correction to the runway length.

25. Runway Length Correction Example
Compute the corrected length of runway for an airport located at an
elevation of 170m above MSL if the length of runway under
standard conditions is 2100m. The airport reference temperature is
32.6º C and the runway has to be provided with an effective
gradient of 0.23 percent.

you don’t learn. If you don’t learn you’ll
never change”
