A single pump system
is a non starter in aircraft.
Lynn E. Hanover
Hi
Lynn,
Funny you should
mention this, because I've actually been contemplating a single pump system on
the single rotor. These pumps are quite reliable, and seem to give lower
readings as they start to wear. I could probably argue that all the
extra plumbing and wiring might cause more problems than it avoids.
Also, no one seems to mind running a single regulator, but that could fail just
as easily.
One thing
I keep thinking about is a conversation I keep having with a couple
RV buddies. One guys wants an auto conversion, but only if it's
as reliable as his car. The thought being that you get in your car and
drive thousands of miles, and don't ever consider what whether the engine
might break on the way there. Using a modern car as the reliability
standard, you have to accept that there is only one of everything (ECU, fuel
pump, etc).
BTW, just to let
you know how abby-normal I think, I used to run both pumps all the time,
just as I also run my boost pump (almost) all the time for the
Lycoming. My logic is that I'd rather find out about a pump
failure when I'm safely on the ground, checking them individually during my
run-up.
I'm certainly not telling anyone to take out their backup
pump, but I'm wondering if I might just leave mine
out.
Cheers,
