Have you all noticed how extremely inconsistent the altimeters are when attempting to set them to indicate field elevation?
I’ve noticed wild variations of barometric pressure reading vs indicated altitude when setting altimeters on the pumpkin and stars stripes to field elevation.
How much does calibration at an avionics shop cost??
Inexperienced nuggets like myself can eyeball somewhat. However; 100 to 300 feet variation from actual altitude MSL can make a world of difference particularly whenever more than two to five miles from the airstrip.
There’s extremely little margin for error when there’s little to no lift on some days. It’s ok for within 2 to 4 miles away or staying in the pattern. Any other distance is potentially uncomfortable below 3000 AGL
