Subscribe Now Carsons argument began with the familiar observation that because airplanes need to climb, their engines are more powerful than they would be if they were sized solely for most efficient cruising. Again, these are indicated airspeeds. Now, miles per gallon is a function of true airspeed, not indicated airspeed.

Consider taking less fuel, cargo, or passengers when operating into high-density airfields. So, on days when we are taking off or landing at an airfield with low air density, we require faster true airspeeds to generate the required lift. This increased true airspeed, along with other factors increases takeoff and landing distances.

Naturally, my first officer and I got a good laugh from this as our 757 was cruising along effortlessly at about 300 knots indicated airspeed, and was not yawing towards the supposedly dead engine. I had also forgotten that today, everyone is an authority on things they know nothing about, such as airplanes.
