400ft .lol. oops. seriously who really flies below 400 ft. i mean if i see a plane in the area i go down to probably around 200 but when i dont see a plane and no one else does im probably up around 700ft. its simple to do. my real rules is once its starts getting slightly hard to see thats ur cue to start going down. vfr rules for me. its pretty amazing when u get a piolet out there start doing circle around the airfield around 500ft. sterman i may add. especially when u have a cvs cam in the cockpit of ur plane kind of chasing him, i wouldnt say chasing just admiring the plane from a distance.
