Reregistering an RAA aircraft

If this is not meeting your fixation needs ("not climbing at best angle or best rate airspeed") sorry.

Did you learn about best angle of climb, best rate of climb and best glide in your training?

 

All I said was higher speed aircraft often have trouble meeting the 5200 rpm minimum at best angle/rate of climb speeds. You are arguing with that but somehow saying you don't need to fly at those speeds?

If you see that your climb attitude (at WOT) is such that the engine is delivering below 5200 rpm,  you should be lowering the nose of the aircraft (subject to terrain/obstacle clearance) so that it can increase air speed

Yes, "subject to terrain clearance" is the important bit. There have been many accidents that might not have happened if the pilot had flown the correct speed for best performance. The quoted performance figures (takeoff distance, landing distance, rate of climb) are null and void if you don't fly the specified speeds.

Flying small aircraft is a dynamic activity

Flying small aircraft requires accuracy, when you care about performance.

But with increasing RPM comes less efficient combustion, an increase in fuel usage (actually wasted fuel), and higher wear levels

Totally dependent on engine design. Look at modern engine design and rpm vs older engines and the comparative efficiency and lifespan.

I " hotted-up " my old lawn mower .

And with a ' faster  spin ' ( RPM ) I . Now I only 'mt' ( empty ) the catcher twice, 

as opposed to four times . 

Much quicker lawn trimming.  LoL

( doesn't matter about the longevity ) . The wife's got the new one .

Modern engines operate at  lower revs and are always Boosted  with incredible torque and Power outputs and an aeroengine is built for different Totally different Parameters . . engine MASS/ Horsepower is  a selling point. Nev
