Did anybody figure out by how much the engine run time will be
shortened after an alternator failure. Now we know the engine will run approx. 1
hour before it quits. The electric water pump will shorten this time a lot I
think. Bulent
This will of course
depend on your battery situation (how many, what size), and what else you need
to run. I believe the Davies Craig EWP only pulls a few amps when running
(added to my note to check this), so it will shorten the time, but not
by enough to keep me from using one.
The unfortunately
point for my setup is that the alternator and wp share a single belt.
If I lose the alternator in flight, I have to assume that the most likely cause
is a broken or thrown belt, which means my mechanical pump is also
offline. Now, I'm trying to save electricity to stretch my battery
only range, but I don't dare turn off the EWP because I'll almost instantly
overheat if the mechanical pump isn't running. Fortunately, a 200 mph
plane can get to an airport pretty quickly, with the help of the nearest
function on the GPS.
Cheers,
Rusty
