If electroair did not result in high CHTs, I would have splurged for it, even if all it did was make starts easier. Getting rid of the 500 hour mag inspection would have been nice. But I'd rather wait for GAMI's PRISM system

Yeah I read the CAFE reports and I was not impressed. High CHTs even with the test aircraft having modified cooling and barely any fuel efficiency gains. The report mentioned that the system sorely needs knock sensors to be effective

Does anyone have figures for amount of oxygen used by a typical person at 24000 feet using a mask?

I am no expert at this but another way of looking at it from the network providers point of view is that a high flying cell phone is logging into multiple towers at once in quick succession. This is theoretically taking the place of other subscribers who may want to use those towers. So a network provider may not like this. If they are smart, they will deny service from some towers (i hear thats the case)

I'd put less emphasis on speed and more on your need to outclimb conditions such as summer haze and buildups, inadvertent icing etc. I have been unable to outclimb some summer buildups over the teeny tiny east coast mountain ranges in the J and that made for a rough ride. And once in the haze one always worries about what thunderstorm cell is growing in there. For a part of the country with mostly fair weather and 300 nm trips you cant beat a J. Then again not everything is a numbers game. If you really want a rocket for just owning one of the fastest singles out there - go for it! I am trying to find one myself

I will have to second that. And he doesnt charge anything to take a look at it and give you his honest opinion.

Ksmooniac - yeah I dont care about round windows much unless its a long body mooney. Rounding the windows on the short body makes the windows appear much smaller in my opinion. 601rx - mucho thanks for those links!

Why would I buy a later model year 231 converted to a rocket versus an earlier model year 231 also converted to a rocket? Fewer ADs? Newer airframe - but does that matter (we are talking 1979 frame versus maybe 1987) What else do you guys think are the differences? Thanks in advance

I believe there was some issue with multiple cell towers responding to device data requests - this happens when you are at 9000 feet and in the range of multiple cell towers. The carriers did not look upon this kindly. If it works - great - but I am going to suspect the carrier will send you a nice letter sooner than later

The accuracy of GPS units is expressed as x feet y % of the time. So 99% of the time it will be accurate to within 300 feet (or some equally large number) 95% of the time it will be accurate to 100 feet You get my drift - as the accuracy increases - the percentage of time the receiver can maintain the accuracy decreases. For the real accuracy figures - you will need to google it - sorry too lazy

Yeah I found out - its about 3k for the parts and 5-6k for labor.

Could we have a copy of your paper ? Before or after Friday..

That was the best pic I have seen on this site yet - one with the 4 Mooneys in formation !!!!

regarding the gear - I try and use it as much as I can as a speedbrake when approaching the airport environment and slow down to Cherokee speeds. Its inefficient but hopefully that will prevent a gear up. also its much easier to remember to do something when not in the busy airport environment. The traffic pattern is where I have gotten distracted with traffic etc and almost forgot to lower the gear - but thankfully caught it before I could really mess up

GPS altitude has nothing to do with any earth reference altitude. What a GPS shows as altitude is derived from the distance of the GPS receiver from the center of a sphere formed by the GPS satellites. This is only a very approximate model because the earth is not perfectly spherical and the GPS satellite constellation has no way of knowing how high the earth's surface is from the imaginary GPS sphere's center. So relying on GPS altitude is dangerous for real IFR flying. The only ways a GPS receiver can get an accurate true altitude is by: Knowing the height of the earth's true surface from the GPS model based on the receiver's horizontal position. Receive signals from ground stations correcting the altitude calculation (WAAS I think) And yes it will be true altitude.

I finish all my other checks before doing the run up, so as to get decent oil temps. After shutdown, I coat the prop with 3 in 1 multipurpose oil to protect it from moisture. I also open the oil access door to help cool the engine faster.

Curious - can you give examples? Thanks

From reading the manuals, the C41 seems to be just as good as the kap. One thing in its favor maybe that its sold new. Is the kap sold new or supported by the manufacturer?

Wow! Curious to know how a 400 foot altitude deviation turned into a court battle. I am sure there are a few accidental deviations happening among the many aircraft flying.

Certainly possible in an emergency. Go back to pure hands on flying and then start pulling breakers. For IFR situations, this is where a handheld radio is critical. Or just turn the avionics master off .. That way you can have electrical gyros running. Anyway this is a good reminder for me to practise flying such scenarios. I normally turn OFF all autopilots on takeoff and landing however

I am in touch with them

And the air then transfers the heat to water molecules, forms large cumulonimbus clouds, which in turn transfer energy back to an unlucky aircraft - circle of life complete. Sorry - in a 3rd rate philosophical mood today

Doh thats a shame and garmin g500 doesnt show engine instrumentation either.

Thanks for the detailed post. My original post refers to an addition to and not a replacement of the required instruments. In other words, the equipment being added is not a primary at all. By legal, I mean legally airworthy, i think, like how you explained. I was asking is there a point between a handheld and an EFIS install where its not legally airworthy anymore. I think the answers above are in conflict.

Okay I played with the simulator and watched the youtube tutorial and this is light years ahead of my 430!! One question for you 480 folks .. How do you use the infrared port to transfer flight plans to the unit? I couldnt see anything in the manual, but the youtube video mentioned the infra red port is used to beam in flight plan information. Although the unit makes it simple to enter the plan directly on the unit itself. But it would be nice to beam it from a computer.
