>>1011157>>1011169What was the terrain elevation you were flying over? VFR Cruise Altitudes start at 3000' AGL
For example, my home airport is about 800' MSL. So I could fly at 3500' MSL, but only be at 2700' AGL, therefore not technically required to fly the VFR Cruise Altitudes prescribed in 14 CFR 91.159
This gets annoying though because let's say you're flying from an elevation of 2000' MSL to 0' MSL (exaggerated numbers just for illustration) at 3500 MSL. At some point you'd reach 3000' AGL from the ground falling out from under you.
Just fly the altitudes anyway, takes a lot of the guesswork out of it.
