Questions from the Cockpit

Phillip, working on his commercial ticket in Florida, writes: “Settle a bet for us here at the flight school: Why is dead reckoning called dead reckoning? Online, there seems to be a lot of difference of opinion about the origin of the term.”

While I agree that it sure seems like a lot of airplanes are running out of gas, to be honest, I’m surprised it doesn’t happen more often. And the reason for that boils down to two issues: First, there’s no way to know how much gas you have in your tanks, and second, there’s no way to know how much gas you’ll need for your flight.

Is it true that if an airplane is completely destroyed, except for the data plate, that you can completely rebuild it, and it’s the “same” airplane?

Almost nobody on the planet truly understands insect aerodynamics — and the few who do can’t explain it to the rest of us. So in that regard, insect aerodynamics are absolutely identical to airplane aerodynamics. Except for the fact that they are, you know, totally different.

Riley, a CFI candidate’s non-pilot flying companion from Florida, asks: “So what’s rotating when you say ‘rotate’ during takeoff? It seems to me to be more of a pull-back than a spinning motion.”

Sandra, a private pilot from Arkansas, writes: As I was flying into a small Class-D airport the other day, I heard the controller tell another airplane to fly a “dog-leg” to the runway. What the heck is that? I can’t find it in the Pilot/Controller Glossary.
