O2 sensor?

I had always thought that Oxy sensors were only used while the engine was
at low power settings, and that once it was cranked up to full power, the
engines ran in a closed loop system, ignoring the Oxy sensor.


My reading of his post suggests it's a "monitor only" O2 sensor. With the
data from the O2 sensor, the pilot then controls the mixture manually.
