Thanks. I guess people in the AVSIM forums actually answer questions
rather than just point people to Google.


To be fair, Google is the place to start.

Interesting question, though.


BTW, exactly who was it said this **** was a master troll?

So go there and ask you questions, and leave us alone. It should be clear
that you are not welcome by most of the people here.

serious personality disorder right there

Same here Dudley..

I have a "few " hours in a 310... I just set them manually, they
stayed in sync very well

I have 2500 hrs on the boat, no auto sync, although they make them.

You engage it once the vessel is moving fwd in gear, then use one
throttle (usually the Starboard) and the Port engine tracks the
master..

The 1st sign of engine trouble is the engines going out of sync
without any aparent reason...

Cheers!

Dave

Yes... it can be REALLY irritating..

I have a twin engine boat, same issue... VERY annoying.. to me, and
many others..

Some don't seem to mind.. (?)

Not only the noise, but the vibrations , when out of sync, can be very
annoying as well...

We had a Cessna 337 on our line for charter use at one time. It had a sync
gauge. Strangely enough, whenever I had occasion to fly this bird I always
ended up syncing the props by ear. You could easily feel if one of them was
out even by a small amount of RPM.

Logically the smallest differences would also be the most annoying,
since they would result in such slow variations. And in theory you
should be able to eliminate them by adjusting RPM manually. But
since the Baron has a prop sync switch it occurred to me that perhaps
the RPM levers aren't precise enough to make it easy to sync the
props (?).


I'm still not clear on whether or not this switch actually moves the
prop levers or what. If it does, it sounds expensive, since it needs
an actuator or servo in the cockpit or along the linkage. If it
doesn't, it means that some of the engine control positions might not
accurately reflect the actual engine settings and that engine
settings might not obey the control movements if prop sync is
operating.

In the baron I got my multi in, you had to first get the props sync'd
up to within 50 rpm. Then you press the sync button and it fine tunes
the prop governors to get them exact. At least thats how I remember
it, it's been a while. Get a POH, it'll have detailed descriptions of
the system. IIRC Beechcraft POH's are pretty expensive (over $100)


Wow, the modern CFI, waht a mrvel he is.

Well I'll bet he can spell-check, fjucktard.

Hmmmm...your command of 'English' speaks for itself.

But your sense of humor is enjoyable. Such irony.

I note that the Baron (and presumably other twins) has a prop sync
switch that somehow synchronizes the prop speeds on both engines.
From recordings I've heard of the interior noise of the aircraft, it
does sound as though props that are just slightly out of sync can
produce a very irritating intermittent noise as they move in and out
of phase.


If you want to simulate that accurately, just talk while your's jerking off
with your sim

Perhaps you could drill a hole in your "English As A Third Language"
textbook and hump the snot out of it.

Leave it open so you might learn something in that 5 second interval
betwixt engage-disengage-ment as you peer out the airport hotel window
for a little (OH!) plane spotting.
