Andrew Choutka
I study aerospace engineering at Purdue and fly out of KLAF, the university’s airport. I’m instrument-rated, and I’m an Entrepreneur First fellow building a hardware company.

Why airplanes bank
Bank a Warrior and split its lift into the part that holds it up and the part that turns it.
Flying in moving air
Hold a heading or fly a course through a crosswind, and see where ten minutes of flight puts you.
Density altitude at KLAF
Take the latest weather at Purdue’s airport through to density altitude, true airspeed and engine power, then change it.
Aircraft
Flight deck
The analog Warrior panel that used to be the home page. Its instruments run on the same KLAF weather.
