      As I get ready to go out and do some coupled approach button pushing and 
      power setting exercises, I'd suggest that a AP setup capable of coupled 
      GPS approaches is such a great capability, that it should be seriously 
      considered.  I'm still amazed that I can setup for a standard GPS 
      T-approach and not touch a thing until DH (complete hands-off requires 
      trim interconnect and/or a modest power setting).  That's airliner-type 
      capability.
      
      I got my rating and have flown 100% of my actual, single pilot sans AP.  
      A wing leveler would have been a game changer, lateral steering heaven, 
      vertical steering unimaginable.
      
      A fully coupled AP means maintaining proficiency at both hand flying, 
      coupled AP operation, and several modes in between.  More work, not 
      less.  But given that, the utility of being able to monitor a fully 
      coupled approach when at a strange airport in low weather is pretty special.
      
      I'm not familiar with the Trio or other APs and EFIS configs, but in my 
      configuration, the AP is one of my main backup options in case of 
      various failures.  It will fly the plane with an otherwise dead and cold 
      panel while I twist-in maneuvers and monitor my analog instruments. 
      Highly unlikely but something else to consider.
      
      In any case, I agree that all of these configurations are great.  The 
      price/performance of these experimental panels is pretty amazing.

      I agree 100% with Bill:
      
      "A fully coupled AP means maintaining proficiency at both hand flying, 
      coupled AP operation, and several modes in between. More work, not 
      less."
      
      This is the airline/part 135 world, where pilots use autopilots all the time but
      also get frequent recurrent training. Unfortunately in the real world of GA,
      not everyone follows this model.
      
      Some people have wondered if the Cirrus aircraft - with its parachute - encourages
      pilots to attempt things they otherwise wouldn't do.
      
      I wonder the same thing about autopilots.
      
      Just my two cents.

      I'm an unbiased observer on this subject .....  I don't fly IFR but do 
      practice the GPS approach available from my Anywhere Map.  If I do 
      something stupid and find myself in trouble, I have an option that may 
      save my stupid butt.
      
      I view a coupled approach as being in the same light.  Having it and not

      It's a tool available to save your butt when the brain goes out to lunch

      Upon reflection, I'd like to share a bit..
      
      Like I said, I went out today for a little training on button pushing 
      and power settings.  A very productive session.
      
      However, going back to my initial flights with this panel, I recall that 
      when I first started to use each function - lateral steering, GPS 
      steering, Altitude hold, vertical steering,  GPS coupled approaches and 
      ILS coupled approaches - each attempt was an adventure and were 
      generally unsuccessful if not a bit scary the first couple of times.  
      And I had a malfunctioning AP just to keep me on my toes.
      
      That's the kind of adventure that can kill you when the shades are drawn.
      
      As Linn suggested, you have to practice if this stuff is going to help 
      rather than hurt.  I'd suggest that if you don't practice, it's better 
      not to even think about it or perhaps even have it.
      
      So, if I were VFR-only I know that I would use a basic autopilot with 
      lateral steering.  I'd use it for altitude hold or even climbs and 
      descents if it had that capability.  Personally, I wouldn't practice 
      full approaches with it due to just plain laziness.  And if I did feel 
      compelled to practice approaches, I'm sure I'd just go get the rating 
      which is what I did.... but even then, I've learned if I don't practice 
      and stay proficient, I might as well stay visual and pretend the 
      capabilities aren't there.
      
      So why not practice approaches "just in case"?  Because if "just in 
      case" happens, the best thing to do is confess, ask for vectors and a 
      descent to VFR.  I know that I can't hand fly an ILS to standard if I 
      haven't stayed current and I probably couldn't get my AP to fly a 
      coupled approach safely if I haven't practiced the button pushing.  But 
      maybe that's just me.

      Ok having trouble with section 29-15.  Step #1, describes dimpling the
      F-1015B Foot Well Rib Intercostals and the overlying F-1015F spacer.  But
      there is no indication that the actual rib, F-1015A gets dimpled.  Yet the
      mid fuse skin is dimpled and lays on top of the rib.
      
      So am I supposed to dimple F-1015A outer web?  Thanks in advance.
      
      Here are a couple of references:

      Having no working AP for the first 26 years of flying including numerous low
      IFR approaches and departures, one learns to be the pilot. Although on an
      IFR plan I arrived for my first two actual IFR approaches with the Cheltons
      in the 10 expecting a visual approach at both RNO and MYJ. The RNO ATIS
      stated "ILS 16R in use visibility 1-1/4 in smoke"; those skyway boxes came
      in handy for the hand flown approach. At MYJ the only weather for 300 miles
      was setting over the MYJ airport resulting in an RNAV6 approach from the
      right seat to a 400-1 in moderate rain. Check out the AP but be ready to
      hand fly; remember the computer between your ears Is much more capable and
      flexible than the AP if the pilot can put the flight path marker where it is
      supposed to be. 
      
      
      Also remember that every once in a while ATC throws a wrench. Last September
      I was cleared for an RNAV 34 into 1H0 in St Louis in IMC. As I prepared to
      join the final and proceed inbound, ATC said that they had a jet passing
      above me and could I do a couple turns in the depicted holding pattern. I
      said OK (they cancelled the approach clearance) and at the fix I turned
      outbound (skyway boxes gone) using the green diamond (GPS track) I flew a
      track of 160 for about one minute and then turned inbound to a track of 340;
      arriving at the fix I again turned outbound one minute then inbound. ATC
      re-cleared me for the approach and out in the distance on the PFD , the
      skyway boxes were still there. The remainder of the approach was
      unremarkable.
      
      
      My advice; if you plan to fly IMC, practice hand flying , learn your
      equipment, work up to the lower minimums. The PFD, MFD, EIS displays make
      this so much easier than it used to be.

      it seems like the airspeed is reading maybe 10mph fast.  The GS always reads

      If there's no electronic configuration parameters to adjust, what do
      you do?  Are there Pitot line "attenuators" like for RF in coax? ;-)

      Listers,
      
      I went flying tonight in the RV-6 around sunset and took some airspeed numbers
      flying the four points of the compass.  I let each direction normalize for about
      2 minutes before taking the readings.  I've still got my little black-tape
      washer deals on the static ports that I detailed in a previous email.  
      
      Do these numbers make any sense?
      Emacs!
      
      I set the altimeter to 30.15 (KLVK ATIS).  I compared the Dynon altitude with the
      Garmin 696 GPS altitude.  The Dynon was high by 100 ft.  I used the Dynon altitude
      adjustment to set it to match the GPS (-100ft).  The readings above were
      after this adjustment.

         You can use either barometric altitude or pressure altitude. GPS 
      altitude is irrelevant, It is a calculation based on a theoretical 
      modified sphere, with some WAAS correction, but ATC and all flight rules 
      are based on barometric altitude. You can derive pressure altitude from 
      baro and vice versa, but you can't replicate GPS altitude. With a 
      portable WAAS enabled receiver I see variations of +/- 150 ft at my  
      home airport in GPS altitude. Yes, it usually is within 50 ft but not 
      repeatedly. Are you certain the inputs for the Dynon to calculate TAS 
      from indicated are correct? Is your indicated temp and baro altitude on 
      the money?
      That set of ground speeds computes to 182 TAS
      http://www.reacomp.com/true_airspeed/index.html
      So your indicated TAS is still 12 kts high.

      Matt,
      
      
      What type/shape of static ports do you have?  I'm wondering if this is an
      issue with flush static ports???  Airspeed indicator results/calibration has
      proven more effective with a static port that protrudes a bit from the edge
      of the skin.
