Anybody got a reference for 50ft? Heard it before, used it myself, never seen it in writing.

I have a reference for 'in the order of' 75ft. AIM 7.2.3.a.3

Quote:

Note the variation between the known field elevation and the altimeter indication. If this variation is in the order of plus or minus 75 feet, the accuracy of the altimeter is questionable and the problem should be referred to an appropriately rated repair station for evaluation and possible correction.

Then, if both altimeters are misreading by 100ft, perhaps the field elevation is wrong?
