 Posted: Fri Aug 29, 2008 4:03 am Post subject: Boost Pump - On or Off for Takeoff? |
 |
|
A few days ago the conversation around our hangar was about the use of the electric fuel pump. I reviewed the POHs that were available on Tim's site and still didn't find a clear answer. So to my question, is the electric fuel pump supposed to be on or off during takeoff? The answer to this question even appears to vary in the certified world, some Pipers have it on for takeoff, some Beechcraft have it off.
The follow up question of course would be, why, or why not?
Thanks, Jason Kreidler

Here is my opinion…..everyone has one.
For fuel injected (IO-540) engines, the fuel pump should be on for takeoffs and landings as a precaution against the mechanical fuel pump failing. It is my understanding that on some engine types, you should NOT use the electric fuel pump because it can cause the engine to flood.
I have the pump on for takeoffs and landing.

Look to aircraft with the same engine and fuel injection and low wings
for your answer. Bonanzas have TCM engines with either a Bendix
pressure carb or TCM fuel injection, with entirely different
requirements than the plane your engine came out of, a Comanche 260.
With the RV10, I'd say have it on. The RSA system(or equivalent) isn't
sensitive to small variations in fuel pressure, and if the mechanical
pump were to fail at 50 ft, you would have a much less eventful flight
if you discovered it at 1000 ft when you turned the boost pump off
than if the fire went out at 50 ft.

Kelly is spot on.
It is insurance during a very critical phase of flight.
For low wings, not a bad idea to have them on in the landing pattern as
well.
