My CFI advised me to take off from my towered origin airport A, fly to nearby towered airport B, fly 60NM to uncontrolled airport C, then back to B, then back to A. That's 3 landings at three points (B, C, then B again), with 3 at towered airports (A, B, and B again). This makes no sense to me.
According to my reading of the regs, I just have to fly ≥150NM with 3 landings other than at my origin, and the furthest field just has to be >50NM from my origin. There's nothing about whether the airfields need to be towered or not.
Am I missing something in
§ 61.109 Aeronautical experience. (5)(ii) ??
"One solo cross country flight of 150 nautical miles total distance, with full-stop landings at three points, and one segment of the flight consisting of a straight-line distance of more than 50 nautical miles between the takeoff and landing locations"
Point (5)(iii) talks about 3 landings and take-offs at a controlled airport, but that's a separate part of the 10 hour solo minimum. Don't most people do that as their first solo? Three landings and take-offs from the traffic pattern?
