Happened to me the other day, (reminds me that I should write a NASA ASRS on it). I was on my way over to a runway and was cleared to taxi via A3
over runway 5-23 then via B to 14. I was merrily on my way and just before I crossed over 5-23 just past the hold short line (I always pause for a second and look both ways because a lot of training goes on at APF
, and many of the students have trouble with english and get confused) as i looked left sure enough someone was on short final for 5. I slammed on the brakes as the ground controller told me and another A/C to hold position (we both had been cleared to cross the runway at different intersections) as we both were over the hold short line I have no doubt that would count as an incursion. Although in this instance it was clearly controller error, I have absolute faith in our nations ATC and have no doubt that it is the premier NAS
in the world. Almost all errors I have personally experienced is a result of a pilot not paying attention.
