Happy Leap Year!

We've got an extra day this year, and in celebration I've got a couple of aviation extras for you:


Have you ever wondered what the most expensive switch in an airplane is?

Here you are; this is it:

The Landing Gear switch. Trust me: airplanes that don't have one of these cost much less to purchase, maintain, and insure.

And how about the most expensive gauge in the cockpit?

The hour meter, better known as the Hobbs Meter, records the billable time in hours and tenths. On most airplanes, this runs anytime the engine is running.

Now you know!
