Since the old one was essentially not worth anything, I looked inside and found that the only problem appeared to be a keeper that had come off of one of the shafts and was not disengaging the gears to set the heading. Had I done that before I ordered a new one, I might have saved a few bucks by fixing it myself. If you find a place to overhaul at a more reasonable price please share. I checked Mid-Continent, and ended up buying one from ACS since they had it in stock. There were some cheaper ones out there, but they did not have them in stock. Good Luck!

You have my congrats doing all your IFR work in your RV. I will fly my RV IFR and use some of techniques you have mentioned in the real world. A hint to stay legal and still get direct: File your flight plan using the V airways. Indicate your aircraft type with the appropriate /. In the comments section put "Handheld Garmin XXX for situational awareness" and also put "autopilot" if you have one. As soon as they hand you off to your first center, ask if you can have direct on such and such heading. Before we installed the approach GPS in the Bonanza, this was my SOP. I've had ATC ask just how was I going to maintain direct. My pat reply was always, "VOR cross checking with handheld GPS for situational awareness". The relpy 99 times out of 100 is "cleared direct, heading XXX". Mike, once again, for heavens sake use what you have onboard to stay safe and dirty side down. If you took my comments as arguing with you, that was the furthest thing from my mind when I posted. If you thought I was, my apologies.......it wasn't intended that way. While I don't think you have to have an IFR ticket to fly at night, I believe the time spent under hood and learning the ATC system makes you a better pilot. Note, I did not say it makes you a better pilot than "him", it just makes "you" a better pilot.

People know how good this hand held stuff is. With all that said, let me flip the coin and tell you what a local controller did to the local university that offers various 4 year pilot degrees. Lexington, KY offers all the approaches out there but to get back into I39 the approach is VOR/DME. One of the aircraft the college flies does not have DME but an old loran. In VFR conditions people were taking the miss on ILS22 in Lex and requesting the VOR back to Richmond. Some new controller with a stick up his backside noticed the aircraft, at some point in time, had filed a flight plan with a / indicating it was not equiped with DME and remembered it. He called the FBO and told them this aircraft could longer be given the VOR/DME to Richmond and if they ask anymore, he would file a report. After this, all you would do is tell ATC, after the ILS miss, you would like direct to the LEX VOR, then direct I39 at 2600. The FAF was well outside the LEX class airspace so all you would is cancel radar coverage and shoot the approach. The log book entry was VOR tracking into I39. This university even had an NDB approach they came up with using a local AM radio station. Where there's a will, there's a way!! Now back to our regular RV programming.

Yes also to a new electric pump and they are not cheap, at least the aviation ones are not. I believe an air flow perf. Pump which I have is in the $800 range. Cause its not just a pump, but bypass valves, overpressure returns etc all in one "pump" package. When you say you have a bendix injector, do you mean the flow metering unit? Flow divider? Injectors and lines? You can see an AFP pump package here: http://www.airflowperformance.com/efp.htm BTW, AFP also sells bendix stuff so you can call them and they could better tell you what to mate it all up with. You may find it cheaper to buy an entire kit from someone than piecemeal what you have. Good luck.

A hobbs meter is very accurate at measuring time, just like your watch. This is great for measuring flight time for your logbook and engine time also. This is a true accurate measurement of time (hours, minutes and seconds) The tachometer measures revolutions, not time. Im my case my tachometer measures 1 unit(hour?) at 2566 rpm. This works out to 153960 rotations of the old crank for 1 unit of time measured on the tach. So if I cruise at 2566 rpm and hour on the hobbs and tach are both the same. If I cruise at 2700 rpm then my tach will measure 1.052 hours for each hobbs hour and at a 2300 rpm cruise my tach will report 0.896 hours for said hobbs hour. So if I run my engine hard (racing to breakfast) I would actually have to change my oil (25 hour interval) sooner that the hobbs would suggest. The hobbs would report 23.764 hours. Now if I take my time going to breakfast and do a little sight-seeing and run at 2300 rpm then I get to change my oil a little later using the tach as my guide. The hobbs would report 27.9 hours but my tach would report 25. If I cruised all the time at 2300 rpm and finally tore down my engine at the recomended TBO or 2000 hours, my tach would say 2300 hours and my hobbs report 2232 hours. The above examples do not take into account taxi, climout or anything but cruise but I mostly cruise so its a moot point. I stand by that the old tach is a better measurement of time for maintainence on the engine in that it is slaved to rpm and not time. In short, your engine wears out faster using hobbs time. Gary, no Hobbs, Zilik RV-6A 471.2 tach hours (at varying rpm) The math may be inaccurate as I used my trusty ole pencil. Original Message: ----------------- From: Wayne R.

Let's assume I have the equipment to do a non-precision approach(VOR),BUT the published missed approach involved a piece of equipment that my plane didn't have(such as ADF). The reported ceiling is 200 ft. above the MDA. Can you "legally" shoot the approach? Sorry to keep the pot stirred,but it is relevant to my home airport and the published missed approach procedures. It has never happened(yet)because so far I've received radar vectors for the missed approach. --- Ken Brooks wrote: > --> RV-List message posted by: "Ken Brooks" > > > Jim Brownfield's comments about the potential > unavailability of GPS > signals in the event of terrorist use of them is > well taken.

Sorry, Could not resist. I have properly inserted myself into the fire-sleeve for all answers to your question. On your ?, I say you can't shoot it, since the missed approach is part of the published procedure and would violate the requirements for equipment necessary to shoot the published approach. But I am definitely not confident of my answer.

It has never happened(yet)because so far I've received radar vectors for the missed approach. Nels, My answer: Yes, if your GPS is approved for either enroute/terminal or appoach operations. Most of your questions are answered in AIM 1-1-21 http://www2.faa.gov/ATpubs/AIM/Chap1/aim0101.html#1-1-21. Note that this is for a "legal" setup and operation. In short an "approved" GPS can be substituted for an ADF or DME if the nav fixes are in the database. This does not allow one to "legally" shoot an approach only labeled as "ADF" with even an approach approved GPS. The approach would have to be labeled "ADF/GPS". There are a number a other restrictions that are described in the AIM.

Also, how do these moving maps handle doing aerobatics? Is it hard on them? Do you just turn them off? Here is a link to the King I'm talking about.
