Good app, cheaper than practicing up there.

I am an instrument rating student and downloaded this app to practice entering holding patterns at VORs and NDBs, works great, it could be easier to manipulate the controls, but works as advertised. It sure beats paying $50 an hour for a simulator or more than that to actually fly, but still does the trick of making your brain think.

As a tip, you can zoom out all the way if you want to simulate partial panel (not seeing the nice glass moving map). It would be great that they added a no moving map option to practice this.
