CECO Vs. Bendix Fuel Controls

[Mike Th...]

Does anyone know the benefits of either a CECO fuel control versus a Bendix
fuel control on the Rolls Royce 250 Series? Aside from the fact that one
works off of air pressure and the other off of fuel pressure is one better
than another?

IIRC after all these years, the CECO allows some modulation during the
start. The Bendix is either on or off. ISTR that we eventually did away
with all our CECO's and went all Bendix, for some reason unknown to the
pilots. Most likely an A&P will jump in with the real story.

Simple - CECO costs more.
BTW Bendix now make a FADEC system for the 250 as well.

Thanks for the link. We operate a 407 and I know about that system but I
didn't know Bendix has a STC'd FADEC.

The system mentioned in the link is not a FADEC. It is an engine monitoring
system that protects from Hot Starts. FADEC does a lot more than protect
from hot starts...

If my memory serves me correctly, Altair is now a part of Pratt and Whitney.
It was only in a partnership with Honeywell/Bendix and never was owned by
them.

I have never had any dealings with the system but the article says:

"Another benefit of most standard FADECs and Intellistart Plus+ is that they
can produce an accurate accounting of flights, starts, torque events,
exceedences, and power checks. "

The Altair system is not a FADEC, it just has some items in common. (FADEC
controls the complete engine) and also records exceedances. (Altair only
controls the start process) and records exceedances.

Just for info.
CECO is now BF Goodrich Controls.
