Right. I should have noticed -- the runway length is less than 1500 feet in those two airports (and in several others in the same BGL).
See this in the MakeRunways README document:
MINIMUM RUNWAY LENGTH
By default MakeRunways imposes a minimum runway length of 1500 feet, otherwise runways are omitted from the data files. This is to eliminate so-called "ghost" runways being included -- very small runways provided only to allow AI Traffic to be directed better for landings and takeoffs.
If necessary you can override this value. Just use a command line parameter in the form:
/>n where n gives the number of feet to be considered the maximum for exclusion. Take care not to make this too small for fear of including those "ghosts", but if you really do want to see all, you can set />0.
Please note, this will only work if you enclose the parameter in quotes, like this: MakeRwys.exe "/>500"
However, I can confirm that with this value (500) it will include both LECK and LEMQ in the output (LECK is 861, LEMQ is 1331)
Hope this helps,
Martin
