This happens alot in TUS. Cause when TUS is using there main runway 11L/29R and your out say in Marana or near Picacho Peak you can't see TUS.
But your sure can see Davis Monthon Air Force base. Even odder still is the fact that both airports are literally no less then 5 miles apart....if that.
And to make matters even worse both rwy's at both airports are the same direction magnetically.
DM is 12/30 and so is TUS but I was told by my flight instructor they changed there numbers at TUS to 11L/29R cause they were so close to DM's that it often caused confusion.
Sure enough when I would line up for takeoff at TUS my compass said I was facing one-two-zero.
But have often heard stories about pilots either landing at DM or on final there for landing and being chewed out by ATC.
Oddly enough on my x-county flight for my PPL I flew from TUS-E63.
But... began lining up for final at GBN...a military base. I'm sure MikeD knows all about KGBN.
Guess I was on the wrong frequency and E63 is a smaller airport but GBN is larger and quite visible from the air and I think there runways at both airports are the same magnetically.
Had I not seen an F-16 off to my right in the far distance I prolly would have landed and had quite a surprise waiting for me.
On a side note I was very fortunate at that time to not get an F-16 military escort.
