Here we go....this might be a PPL question but I'm thinking it's really a maintenance issue.
I'm at home field, altitude 5510. I set the altimeter to that altitude. Yesterday when I got the ATIS, the difference on the Kollman was 0.50 so when I set to the ATIS, the altimeter read substantially lower (like 400 ft!) than field.
Another data point - temps were in the 80s, so DA was much higher than field.
Question - do I need to send the altimeter to the shop?
