Basic Runway Length
Correction for Elevation, Temperature and Gradient
Correction for Elevation
[`L'= L.(7/100).(E/300)`]
L1 = L + Lc
E = elevation from MSL (m)
L = Basic runway length
Lc= Correction due to elevation
L1= Corrected length
Correction for Temperature
Correction for Gradient
Basic Runway length
Length of runway under following assumed conditions
(i) Airport at sea level
(ii) Temperature at airport is 15 'C (standard)
(iii) Runway is levelled in longitudinal direction.
(iv) No wind blowing on runway.
(v) Aircraft is loaded at its full capacity.
(vi) There is no wind blowing enroute to destination
(vii) Enroute temperature is standard.
