Nitpicker - "Remember that in a Jet Pitch controls Sink rate and thrust controls Speed."




Two examples -


I do a loop. In afterburner and my thrust to weight is less than 1:1.


450 kts, full afterburner, and I pull back on the stick. What happens to speed? Remember the quote is "thrust controls speed".


Aviation Week and Space Technology's latest issue has several articles about stalling airliners. And they talk about the wrong reactions the majority of pilots have. Thrust is the not the primary recovery tool.


Wait a minute, I thought thrust controlled speed? If that's true wouldn't thrust be the first response?


The reality is in normal line ops the difference between thrust vs pitch controlling airspeed, if you're close to normal speed/sink, is tiny. It's when people get to the edge of the envelope that it becomes obvious which is the ultimate controller.
