Nephris mentioned in another post that one can make use of both by:

 

"...pointing the first coordinate directly on the first runway and the last coordinate on the second runway.

You then call it German_airfield and German_airstrip and you can make one location capable of double aircraft amount."

 

How exactly is that done? Just creating a link between the two in the .rds?

Using the Slovakia map for example.

Open it with the Full Mission Builder.

 

In B5: Piestany.

In B6: Piestany Home Base.

In B6: Horna Streda.

 

At Piestany Home Base there are 7 icons.

 

X   X   X + runway threshold marking + X X X X

It'll be difficult to use all of them.

But we can easely use 4 of them.

X        X + runway threshold marking + X        X

 

Their location's names will be (from right to left):

 

Piestany_Runway1_Airstrip

Piestany_Runway2_Airstrip

Piestany_Runway3_Airstrip

Piestany_Airfield

 

Now the roads. They can be:

 

[somewhere to Piestany]

[Piestany to Piestany_Runway1_Airstrip]

[Piestany to Piestany_Runway2_Airstrip]

[Piestany to Piestany_Runway3_Airstrip]

[Piestany to Piestany_Airfield]

[Piestany_Runway1_Airstrip to Horna Streda]

[Piestany_Runway2_Airstrip to Horna Streda]

[Piestany_Runway3_Airstrip to Horna Streda]

[Piestany_Airfield to Horna Streda]

[Horna_Streda to Elsewhere]

 

For each road, just follow the rules about waypoints, distances etc...

 

Let your imagination run free!
