    Grass Runway Landing Training

    We did a couple of patterns at the grass ag strip next to the Cedar Lake VOR. I think the folks who really have it right, though, is the school at Aeroflex Andover in NJ. The students there start their primary training in taildraggers on grass fields, and never get exposed to trigear a/c...

    What or who was your inspiration to fly?

    Rides in a Supercub in Alaska prodded me into getting my PP-ASEL rating. After that, I discovered that I liked low and slow, not high and fast, so I took an intro helicopter lesson in a Schweizer on my 60th birthday. I loved every minute of it. Just before moving to Pennsylvania, I bought...

    R/W Stage-1 Check Ride Prep: Limit Manifold Pressure

    Joe, somewhere in the back of that swamp I call a mind, is the recollection that a number of early helicopters didn't have correlators. I even seem to recall, but can't confirm, that the very early Bell 47's didn't have a correlator either. Now, that's got to increase the pilot's work load!

    That's true, Lance. He's a bi-aviator like me!

    R/W Stage-1 Check Ride Prep: Limit Manifold Pressure

    My pleasure Tony! There's a huge knowledge gap between fixed-wingers and us lobotomized flingwingers (it was Laurie who suggested we are lobotomized... she may be right!). But there's also a huge gap between powered pilots and glider pilots too ...

    R/W Stage-1 Check Ride Prep: Limit Manifold Pressure

    If the governor bites the dust (rare but does happen) then the pilot uses the collective as he normally would. There is a throttle correlator which adds throttle when he raises the collective, and backs it off when he lowers it. Most of the time, unless he does abrupt maneuvering, the...

    R/W Stage-1 Check Ride Prep: Limit Manifold Pressure

    You've got it right, Tony! With a constant speed prop, the pilot manipulates engine RPM with the prop control, and power with the throttle, and the job of the governor is to maintain RPM by varying prop pitch. In a helicopter, the pilot manipulates pitch with the collective, and the...

    R/W Stage-1 Check Ride Prep: Limit Manifold Pressure

    More correctly, the carburetor air temperature gauge. But your point is true. Not only will the governor possibly mask a carb ice problem, but may mask other power plant related problems as well. The 80% is a Robinsonism (if that's a real word) and is arbitrary. Robinson changed the...

    R/W Stage-1 Check Ride Prep: Limit Manifold Pressure

    Actually, practice autos are kind of fun, Tony. The factory puts out the 1.5 second number, but there's been lots of discussion about it. Many pilots believe that you've got 5 or more seconds to floor the collective before the RPM gets so low you can't recover. If you have airspeed, it can...

    R/W Stage-1 Check Ride Prep: Limit Manifold Pressure

    Tony, with a properly functioning governor, the RPM should never get out of that very narrow green zone. The exception is at high DA when the governor fully opens the throttle but the ship needs more torque to maintain RPM. Most helicopters (at least the ones I've flow) have an allowable RPM...

    R/W Stage-1 Check Ride Prep: Limit Manifold Pressure

    It's a little different in most helicopters Lance, because, unlike a constant speed prop, RPM is fixed by the governor. Full throttle means what you said, but it's a dicey area -- if the pilot attempts to pull more pitch beyond that point, the additional drag will cause RPM to decay. Normal...
