I was flying once into KPIT. FAA inspector in the jumpseat. Radar says traffic at 11 o'clock, two miles.
We see it and report it in sight.
JUST THEN we see another plane, same bearing and closer.
whoops!
Radar told southwest the airport was blank at 14 miles. There was an airport out that way but visually determining distance, at night is tough.
BUT, with the published level of experience and all the navigational equipment on board there were other ways of verifying an airport that neither pilot had been to at night.
In my case we didn't even have TCAS then.
USE everything you have!
