Oh here we go the old Pitch for speed or power for speed argument again!
Both camps talking absolute rubbish!
Think energy management a new phrase!
In a SEP you have two throttles! a conventional one attached to the engine and another attached to the airframe.
Think along those lines and you will not go far wrong!!
There are times especially in a low powered aircraft where full power will not control your speed and you will sit there like an idiot full power watching the speed falling away.
What can you do? Tap into your second throttle by pitching forward reducing AOA and drag and tapping into your second source of energy the airframe.
Fly straight and level! Leave your engine power where it is and note the speed 100 kts? Now tap into the second engine ie the airframe and start using the potential energy by exchanging altitude for energy.
Miracle of miracles the airspeed as you pitch forward increases as you have two big engines available to you and two sources of power.
Both concepts of pitch for speed or power for speed are absolute unadulterated RUBBISH think two throttles two power sources and use them together or apart.
Low powered draggy aircraft and pitch takes superiority as it does with novice learners who need to be kept away from high AOA high drag low powered situations!
Jump Into a Lightning and forget pitch for speed as you will go vertical to 40,000 feet
But above all stop this silly argument and PLEASE SEE THE BIG PICTURE!!!!!!!!!!!!!!!!!!!!!!
