I part-time CFI (Active Duty still) and initially I wasn't certain I would keep the pro subscription.

It probably also hinges on the training fleet avionics setup. But from an app point of view, I think it it is worth it.

In the last several months, I have been doing a lot of instrument and ATP flights. In my local area, we can do the flights under VFR without working with ATC and I have access to all the approaches; VOR's, ILS, GPS, etc.

I like having the pro subscription as I can give the student great vectors when I play ATC with the geo-rectified plates.

Also, it would be nice to have when it comes time to shoot the approach in IMC.
