"Act like you've been here before."

Standard advice to rookies.

The guy checked in with approach. Approach control gave him the current altimeter. It was .01 different from the ATIS that was about 55 minutes old. Hardly earth shaking ("act like you've been here before"). The guy responds in an irritated voice. Deathly silence on the radio during a busy period. Finally broken by "rrrreeaaallly????" It was pretty damn funny. Even people with a poor sense of humor should have been amused.

It was a .01 change. It wasn't the first time in aviation history that the altimeter had changed by .01. Hardly worth being irritated that the ATIS hadn't been updated.

Every company I've worked for, to include the U.S. military, had zero interest in accurate information. We just wing it.
