Squawking Your Parrot

If you've ever topped off a 737's tires (bet you haven't), or if you're a fan of NASCAR, you know that they fill up their wheels with Nitrogen. But why? And should light GA aircraft do the same? We take a look at the science behind dry nitrogen - and whether the payoffs are worth the cost for your plane. And, have you ever wondered where your squawk code comes from? We take a look at how a Parrot evolved into your transponder - and how the ATC system divvies up squawk codes for VFR and IFR flights. This show is sponsored by... our training courses! Out of everything we build, they're our favorite products. They'll make you a better pilot - whether you're a student or a veteran. Check them out at
