Hi,
I'm just wondering if someone could share some experience flying Beech Sierra. Any information about positive/negative sides, flying tips, and etc. are appreciated.
Thanks
But you will pay twice as much for the Six. OK, maybe not twice, but 1.5x.You can probably operate a Cherokee Six for the same annual budget (difference in insurance cost makes up for difference in direct operating cost), and get more room and speed.
...and you'll get that much more back when you sell it, too, and have an easier time selling it, to boot.But you will pay twice as much for the Six. OK, maybe not twice, but 1.5x.
Where's that written?i know lycoming recommends "idling" at around 1000 rpms to help keep the cam lubricated.
Where's that written?
Its written on the Citabria Forum. That means it must be true right?
I did find this though: http://www.lycoming.com/support/publications/service-letters/pdfs/SL185B.pdf
Top of page 2 recommends a ground operating speed of 1000-1200 rpms. doesnt mention cam lubrication though, mostly keeping spark plugs hot enough to avoid fouling.
The cam lube reasoning does make sense to me though, particularly if the engine is cold and the oil is therefore rich. Either way it is manufacturers recommendation to run about 1000 on the ground.

The full quote is, "The engine should be operated at engine speeds between 1000 and 1200 RPM after starting and during the initial warm-up period." [emphasis added] Once the engine is warmed up (oil temp in the green arc), that no longer applies. Also, that SB is entitled "The Use of Higher Octane Aviation Fuel, 100LL Blue or 100 Green, for Engines Rated for 80/87 Octane Fuel." The recommendation may or may not apply to engines rated for 91/96 or 100/130 octane fuel, although I do recommend it for initial warm-up of all engines running leaded fuel regardless of the engine's minimum octane rating.I did find this though: http://www.lycoming.com/support/publications/service-letters/pdfs/SL185B.pdf

Can you provide some examples?It's also implied in many aircraft checklists straight out of the POH.

I don't remember seeing that in the C-172P POH.Cessna 172P calls for 1000 rpms, IIRC
I don't remember seeing that in the C-172P POH.
This "1000 RPM" thing is a good example of how various OWT's or out-of-context partial quotations become "book procedure" by the time they're on their third distorted retransmission. Example: Think about the number of folks who honestly believe (without having actually read the book) that there's a POH limitation prohibiting slips with flaps extended in all Cessna singles.
1984 AIM, C172P:
Page 4-8, "Before Takeoff" Checklist:
Line 12 (following run-up): Throttle --1000 RPM or LESS
With regard to slips in the 172P:STARTER -- CHECK DISENGAGED (if starter were to remain engaged, ammeter would indicate full scale charge with engine running at 1000 RPM).
That's a far cry from "prohibited." I'd be more interested in the student telling me why a control surface supposedly affected by air pressure is suddenly capable of oscillation.Steep slips should be avoided with flap settings greater than 20° due to a slight tendency for the elevator to oscillate under certain combinations of airspeed, sideslip angle and center of gravity loadings.
I'd like to see that if at all possible.Kenny I had a 1981 P model book.
The flap thing has wording that has changed apparently over the years. i am most familiar with the placard that states that "Slips are prohibited with full flaps extended" the key term being Full. there is a possibility of the so called Oscillations of Doom taking over. Jesse has a video of the Oscillations of Doom. Pretty Scary Stuff
I'd like to see that if at all possible.
Thank you! I appreciate that.PM Sent.
During the warmup period, yes, and that's consistent with Lycoming's recommendations, but not after the oil gets up into the green arc.On page 4-22, in the Cold Weather Operating section, it recommends a warmup period at 1000 RPMs, like Lycoming.
To quote Dr. Bruce, [sigh].Oh like the Designated Examiner for my last PP student?
If you find a C-172 with such a placard, suggest to the owner that s/he recheck the C-172 TCDS, as no such placard is currently required by the FAA, but one that uses the word "avoid" is so required.Kenny I had a 1981 P model book.

TCDS? Help me out there. Thanks.If you find a C-172 with such a placard, suggest to the owner that s/he recheck the C-172 TCDS, as no such placard is currently required by the FAA, but one that uses the word "avoid" is so required.
The 172N's that I fly have a placard that says, "Avoid slips when flaps deployed." It's not prohibited, but not recommended, thus I wouldn't use it unless absolutely necessary.
I don't do forward slips with the flaps deployed.
