Hey Happy,
Glad you made it safely to the ground. Have you still got the Raven II? Mine's flying like a dream and I'm up in it most days weather permitting. Changed the governor as you pointed out and no problems so far. I'll be flying her back to Denham shortly for the 50hr and for re-tracking as it would have bedded down sufficiently by now. Maybe we'll meet up and if so it would be nice to fly each others machines for comparison.
Talk soon...James

im verry interested in your theory about less oil being cooler, you said; Heat energy in its pure form cannot be made or destroyed just moved - First Law of Thermodynamics.
so if the gearbox heats 1 litre of oil 10deg in one min, then the cooler must be capable of cooling that litre 10deg in one minute aswell. if i put another litre in the gearbox the temperature will only rise at 5deg in one minute but the cooler will still cool one litre of oil 10deg. in that time. (no difference)
you also said > The rate through the cooler is constant and with more oil in the transmission it stays there longer to absorb more heat.
but heat rise in MORE oil would be slower! oil stays cleaner longer aswell (impuritys that are suspended are more dispursed) i think reserved oil could only be a good thing.

I seem to remember something in the flight manual of the PA 31 that said something about watching for increased oil temperature if the pressure gauge fails. I don't think it's a fallacy that the oil gets hotter if it has to work harder - it seems to depend on the positioning of the temperature probes and how much oil is going over them.

B206 weight & balance
Hi there
I am looking for some software that will calculate the W & B for a B206 III. I came across it about 18 months ago, written by a pilot in Excel, quite good, but have lost it.
Thanks

Have a look at the helicopter planning page of B206 CofG
If that's the sort of thing that you're looking for then I'll e-mail a copy!
I'll swap it for a good logbook spreadsheet that does flt duty reports!!

There is one at www.electrocution.com/aviation.htm (just scroll down a bit), together with many others. It takes into account the changing C of G of the fuel system. There's also a duty hours spreadsheet, albeit Canadian, but you can adjust it for other purposes.

Jetranger Solo from LH Seat...
With the Ascot time here once again, I was reminded of the arrival last year of a B206 with the pilot flying solo from the left hand seat. I believe the aircraft had just completed a dual flight somewhere and then positioned in.. At the time there was a bit of a debate of the legality of this... Not having a flight manual in front of me I cant say for sure if there is a restriction, however there were some very experienced people on site claiming it was perfectly legitimate.... Could this relate to the age of the aircraft? Have had this before with flying the H500 from the left and then the early military version OH6 from the right.
Surely if there were to be an accident, questions would be asked?? Certainly precludes even attempting an air restart, and makes shutting the engine down when the engine catches fire even more exciting than it would normally be....

I´m 99.9% sure that the B-206L1 POH states that "minimum crew is one pilot and the aircraft shall be flown from the R/H seat"!!!
Don´t have the manual with me though.
And I´m 100% sure that the B-222 I fly say´s that the helicopter shall be flown from the R/H cockpit seat.
However I have also heard that the B-206 is often flown from the left seat particularly for sling work. There may possibly be a way to do it legally.

Must have had some form of dispensation to be confident of flying in to an event where ramp checking is almost a certainty.
As stated last year - the manual says that the ac should be flown from the RH seat. A quick search should satisfy.

Its obvious that it can be flown from either seat. Others are correct in the "Legality" of it based on the manual. If you can see the Pilot flying it that means an air start is impossble because it takes a few thousand feet to get it started and the pilot to quit shaking after the experience.
Some Im sure are STCd for left seat sling work. More common in the Bell 205

You are right Bert, there are a number of operators with STC's permitting operations (primarily for sling work) from the LH side on various machines. In the old days I have even seen field approvals on 337's permitting this.
In order to complete this modification, all applicable controls are moved to the left-side, so that the RH controls can be removed completely to meet contracting requirements (if applicable) that do not allow controls to be installed with pax in the seat.
Then there are the 205/212 guys that operate from either seat, dependent upon the mission.

Single pilot on LHS with low fuel load in a A/C with anti clockwise MR direction ( Left skid low) I would think that you would be getting close to it,s lateral C of G limit.
I tought a very lightweght female in a 206 and that was noticeable but I cant get to my POH at present so cant check

The reason for the RH seat only limitation was a crash in the early to mid 80s where the LH seat pilot had the cyclic come off in his hand because it was not put in properly. Not sure of the outcome of the incident, but the end result was that Bell said - thou shalt not, as well as changed the design of the cyclic and collective so they could not be installed incorrectly.
Interesting bit of work.
Basically, if you fly it solo from the LH seat and crash, your CofA is invalid, because you broke a limitation...
Now if someone has an STC for a more permanent cyclic and collective installation, that might be another story.

Bell 206's have been flown, legally, from the LH seat for at least 17 years (that I know off) so probably more.
The nice thing about fat pilots inthe LH seat, is they carry an equally large lunch in the RH seat, so no CG problem there.
I have a good friend who landed his 206 after bimbling around the mountains and had the RH cyclic break off in his hand! Snapped right off at the airframe fitting!
The STC's are out there for this.

auto pilot, 206B
Hi,
I was wondering if anyone had any information on the auto pilot used in the 206B's. Price, capabilities, and such. I don't know what brand or manufacture. I just noticed a 206 for sale that had one and was interested.
Also, is the air condition that's a available for the 206B's worth a cr_p? I know the AC in the EC120 drips water on you most of the time. It does keep you cool, or at least more comfortable, but you do get dripped on. Any comments, good bad or otherwise.
thanks.

Don't expect much power available if you fit airconditioning. As for the autopilot, I know Collins made some, but there was a different suffix if Bell fitted the, although it was the same product.
Worked fine in the LongRanger I once flew.

I believe that there are (were) some autopilots available for the 206B. It was (is) a contractual requirement for night Marine Pilot Transfer work in Western Australia. Jayrow used to have 2 machines fitted with them.
