You know what's worse than a helicopter pilot? A helicopter pilot that takes themself too seriously.
On the Cessna twins, you need to know High fuel pump is 22 Lbs/h, used only as either primer or if the engine driven pump fails. But with 22 Lbs/hr you cannot get full power on the engine. Low fuel pump is 5 Lbs/h used for Hot Start assistance, Take/offs and Landings, and usually left on during flight.Got recurrency coming up. Doing the usual last minute study my ass off. I’m a pilot not a A&P. I’m not allowed to mess with anything under the cowling.
WHY DO I NEED TO KNOW THE PSI OF MY FUEL PUMP???
I’m not allowed touch the fuel pump. I have no gauge in the aircraft that tells me the PSI of my fuel flow. I’m not even sure where the fuel pump is on my aircraft (I’m pretty sure it’s on the outside of the right horizontal stabilizer). I’ve got a fuel flow gauge but it’s in gallons per hour. So why do I need to know the fuel pump PSI?
“It’s in the book”...I disagree with this. Strongly. And maybe it's because I've spent the last 14 years flying extremely computer controlled aircraft, but I get really nervous when I watch a captain use their systems knowledge to try to explain a symptom we experienced to a mechanic.
Just explain EXACTLY what happened and let MX do their job.
