Is it necessary to manually (constantly) re-tune
mixture or is this automatic, once the base maps are set? Single Lever -
"no need to think about" - operation?
I think the key word is “necessary”.
Once the correction tables (maps) are set; and you set them for mid O2
sensor reading and 12:00 o’clock on the mixture knob; you can fly any
part of your regime without doing anything, and you will be OK (except for when
the engine is cold). But for max power on takeoff and climb you will
likely want to run more rich (1:00
– 2:00 o’clock on mixture knob), and
for lean cruise you will want to lean (maybe 10:00 -11:00 o’clock,
and mixture monitor off the bottom of the scale). So, yes; you will
probably want to still think about the mixture now and then.
I offer these things based on my system,
and somewhat limited flight experience; not as the consummate expert.
However, it could be that I have done more tuning of the engine than anyone
because of the issues I had with the spontaneous changes of settings.J
