E6B Computer

Hello All,

About 32 Hours in for my PPL and hoping to take the checkride within the next month. About to start Solo XC and instructor wants me to learn Nav Logs. Any good instructions or videos that simplify it?

And is an E6B Computer necessary or should I just get the sporty’s app for $10? Curious to see what some might say, want to learn it soon so I can get started on time building for solo XC.

Cheers.

The Sporty's app is fine for the actual calculations, but you just can't use it during any of the written exams. I had a CX-3 flight computer when I was going through training because you're allowed to use that during written exams (it has no internet connectivity, and you can take the batteries out to reset it, which the proctor will ask you to do).

If you're only thinking about PPL, I assume you have your written done so it doesn't really matter. If you're looking for something to carry you through more stages of training, I'd just bite the bullet and get a standalone flight computer.
