Prop pitch cycling?

Sounds good. Right now I'm trying some cheap brandy, but
Jack is awfully good. I don't drink much, maybe one once a
week now. But I'm going to have one tonight, a toast to all
the WWII pilots, to Scott Crossfield, to Dale Earnhardt and
to Tiger Woods dad. And all the troops in harm's way.

| | On Usenet, if you underpost someone already in the
thread
| but NOT the
| | original poster, what you post is considered addressed
to
| the person you
| | underposted rather than simply an addition to the
general
| thread.
| | Any general comment should be picked up as a post to
the
| original poster by
| | clicking his/her post for reply. Then the comment
appears
| referenced to the
| | initial question and not the sub poster.
| | I did the same thing once and gave a hundred word
| "lecture" on how to do a
| | slow roll to one of the world's best acro pilots by
| accidentally picking him
| | up to underpost instead of the initial poster who had
| asked about rolls. :-)
| | The pilot I gave the lecture to simply gave me a one
word
| reply "Thanks"
| | with a smilie attached :-)
| | That get together sounds like fun. I'll bring the
bottle!

| | No, I know that, I just tacked it on the thread for
the
| | benefit of the others. I think most pilots and many
| | mechanics don't really understand these things,
judging
| by
| | the number of twins that feather before the prop
lever
| gets
| | to the gate.
| |
| | If I win the lottery, odds 146 million to one, we
can
| have
| | that CFI round table and sell tickets to anyone
without
| a
| | CFI. CFIs can come for free. I'll pay for you and
me.
| If I
| | don't win the lottery, it will have to be in
Wichita,
| can't
| | afford to go elsewhere without the lottery. ;-)'

| | | The prop governor controls within a range and
should
| | hold a
| | | steady rpm within that range. When the run-up
is
| done
| | at
| | | say, 2400 rpm the prop should be cycled to the
| minimum
| | rpm
| | | and allowed to stabilize for a few seconds to
check
| that
| | the
| | | governor is working properly. On a multiengine
| airplane
| | the
| | | prop should be reduced to just outside the
feather
| | detent
| | | and allowed to run for several seconds to be
sure
| that
| | the
| | | prop isn't feathering at the minimum governed
speed
| | [usually
| | | 2000 rpm on most piston engines]. If the prop
| control
| | is
| | | not rigged properly the prop will feather too
soon.
| | Then
| | | the prop feather check should be done.
| | |
| | | Most props have a certain amount of internal
leakage
| to
| | keep
| | | warm oil circulating in the prop hub, but
several
| cycles
| | on
| | | a cold engine/prop will assure that the prop
does
| reach
| | | proper operating temperatures.
| | |
| | | In very cold temperatures, I like to vary the
rpm
| every
| | some
| | | often to be sure the prop is functioning, but
normal
| | | internal flow should make this mostly an
unneeded
| habit.
| | |
| | | Remember, on a single-engine reducing rpm send
oil
| to
| | the
| | | prop and on a multi, reducing rpm/feathering
drain
| oil
| | from
| | | the prop.

| | | | Hi!
| | | |
| | | | I was told by my mechanic to only pull the
prop
| | handle
| | | until I could
| | | | audibly
| | | | hear a slight pitch change to establish that
it
| was
| | | working.
| | | |
| | | | However, the aircraft manual says it should
be
| | cycled
| | | completely, and on a
| | | | cold engine three times to make sure oil is
| applied
| | to
| | | the governor, or
| | | | the
| | | | pitch mechanism.
| | | |
| | | | Can someone elaborate on this?
| | | |
| | | | What is recommended?
| | | |
| | | | Thanks,
| | | |
| | | | Frode
| | | |
| | | | POH rules of course, but aside from that, I
always
| | liked
| | | to exercise a prop
| | | | through several cycles, especially when cold,
just
| to
| | get
| | | everything nice
| | | | and warm and fluid up there.
