1000 above, 500 below when flying below 10000 MSL, and 1000 in both
directions when flying at or above 10000 MSL. So you cannot fly a
pattern at 1000 AGL in Class E if you have a ceiling of 1500.

This applies to the United States (FAR 91.155); I don't know about
other countries.

So if you're at 1000 AGL and the ceiling is 1500, how are you not
500 feet below the clouds? And why you cannot fly the pattern?
