does flare count as port length? In a roung flare port... thank you...

Add 1" to the length of aeroports compared to a non aeroport.

subtract half of the flare radius

What if you only have one end a flare?

then only add 1/2 as much

4" aeroports count as 3" of the port length.

nG

then only add 1/2 as much
