For the SR22 owners:
When do you execute your first power reduction after takeoff?
I climb full power until levelling off and then lean the engine to LOP. During the climb, I only lean per the max fuel flow chart on the panel. After the first 1,000’ AGL, I typically increase and hold my airspeed between 120 and 140 and climb at about 1,000 fpm (unless my wife is with me and then do about 700 fpm - she feels that higher rates of climb are less comfortable and more dangerous, and it is only by her good graces that I get to fly at all[;)]). If obstacles or other concerns are an issue, I’ll continue a higher performance climb as necessary.
The recent AvWeb article (Great article, BTW) and others have mentioned reducing power anywhere from 1,000’ to 2,000’ AGL and leaning from there. From my perspective, the high power climb seems better. My thoughts are:
- Easiest, least amount of effort.
- Never have to worry about accidentally going too lean during climb. Unless, I’ve missed something, you still have to find PEAK EGT in order to settle on 75 - 100+ degrees ROP.
- Never worry abut engine temps.
- My climbs are rarely longer than 7-10 minutes (6,000 - 9,000’ MSL), and even if I climb to 11,000’ or 12,000’ MSL at my wife’s climb rates (700 - 800 fpm), I am still leveled off at less than 15 minutes from wheels up.
- Gets me to cruise, LOP setting quicker.
- Avoids the annecdotal, engine failure at first power reduction, or at least gets me a lot of altitude first.
- Engine runs dirtier.
- More noise, inside and out.
- Less fuel efficient.
I’m still young enough to change, so I’d like to hear from others…
