Sounds nifty. Will it work for multiple tow planes? Will multiple tow planes go to one spreadsheet in the cloud so pilots can be given read access to verify tow hight, number of tows, and amount owed, and treasure/ops given permission to mark as paid?

Seems like a lot of going back and forth from logger to tow plane back to logger then upload. Why not have tow plane put in tail number of glider, then apps does everything else through smart phone? Kinda like auto upload to OLC.

Cloud Spread sheet has: Tow plane / glider tail # / tow height / take off time / land time / tow cost / paid

clicking on the spreadsheet can organize by tow plane, glider tail #, ect. One can then see how many tows each tow plane did, how many tows a glider did, total cost for that glider, ect.

Good luck, have fun.
