The MSL/AGL issue has come before the Caesar Creek Soaring Club Board
once again. Not only has the Club been thrown into turmoil again, this
time it has specifically affected our instructors and how to most
effectively teach our students. I am curious if there are other Clubs
or organizations that teach using AGL.

Ka boom.

Excellent analogy. But the mechanicals are not there to set an
altimeter to zero at Tonopah. It does not unwind that far. And if
you've flown around Tonopah, you know the valleys are around 5500MSL,
and the "ridges" can be above 11,000MSL.

Pilots need to do the math from day one. Fly on MSL, every one else
does. Learn to compute AGL from MSL minus
chart elevations below you.
