 Colyn and Dico,
 
 Valley performance is great if the other aircraft is properly  equipped.
 
 You did not have TIS-B, just TIS.  TIS is only available in  limited areas
 (like within 50 NM of KORD).  See slide 11 of the attachment.  I have a
 Garmin 430W and GTX 330 so I can get TIS if available.  TIS is  easily
confused
 by closely crossing airplanes or your own steep  turns.  ADS-B knows when
 your velocity vector is changing because of the  high xmit/receive rate.
 
 Hey, I am gaga over ADS-B, it is here today and IS your future in a  mere
 7.5 years.  Some Display and UAT systems come in around $5500. Check  it out.

 Read the TCAS-II limitations at the end of the attachment.  Don't dive  
 unless you have TAWS.
 
 The following is an outline of a presentation I recently made to an  EAA
 group.  Attached are the PDF slides.  I have a demo program on my  laptop of
 the SkyVisionXtreme that I use with the  presentation.  If you want to see a
 demo, look for a dealer in your  area.  Uh, I would exude my gaga-ness in
 front of a group for  expenses. Maybe....

 ==========================================Supporting text for  
 PDF.================
 
 SLIDE 1
 ADS-B
 The NexGen system relies on  GPS-WAAS, ADS-B and the participation of GA
 for flight safety and  efficiency.  ADS-B services include  weather (FIS-B)
 transmitted from ground stations and traffic (TIS-B) available  directly from
 other ADS-B equipped aircraft or from the same ground stations  that have
 also acquired aircraft location information by any means.  There are other
 services, but these are  the most important to non-commercial GA.  When
 complete in 2013, there will be about 800 such ground  stations with 393
operating
 today (there were only 331 at the end of February  2012).  
 SLIDE 2
 ADS-B in  2020
 In the continental USA and by  2020, aircraft must be broadcasting ADS-B
 OUT data (altitude, location,  direction, speed, ID, etc.) in class A, in or
 above class B and C airspace and  within a 30 NM radius of B and C airports
 or in class E at an altitude above  10,000 MSL, but not at an AGL of 2500 or
 less (in class E).  In other words, if you fly out in the  weeds and never
 go anywhere important, you need not deal with this.    
 SLIDE 3
 There are special  non-compliance allowances for aircraft with no
 electrical system, balloons and  gliders.  So it’s still heads up out  there.
 
 Perhaps the FAA will require  UAVs to send ADS-B OUT data.    
 OUT information may be  broadcast on the UAT (Universal Access Transceiver)
 frequency of 978 MHz or on  the current transponder frequency of 1090 MH,
 commonly known as Extended  Squitter (ES).  But wait, there’s a  special
 mandatory rule for flights at or above 18,000 MSL – ADS-B OUT must be  
 transmitted on 1090 MHz ES even if it is also transmitted on 978 MHz.  OUT
data,
 whether via transponder ES or  UAT must be conditioned by GPS WAAS position
 information for  accuracy.
 If you fly at or above FL180  and are thinking about replacing your
 transponder in the near future, consider  one that transmits ES or is easily
 converted to such transmission at a later  date.
 The UAT operates on a  different frequency because there are bandwidth,
 framing, rate and interrogation  limitations on the overworked transponder
 frequency.  
 But, not to worry as these  specific requirements are merely 7 years in the
 future.

 these  boundatries.

 TRAFFIC
 SLIDE 9 – This is why ADS-B  out is needed.
 T1 –T4  SLIDES 10, 11, 12, 13 pix taken with my  iPhone.
 10 – Note the Monroy display  indicates an aircraft at 2 miles. Not seen on
 the 430 at 50 mile  range.
 11- TIS traffic page shows it  up. Direction vector accurate within 45
 degrees.  Trend shows descent.
 12 – Can’t se nothing at 2  miles, so I had to chase the bogie……..
 13 – See that dot I the middle  of the screen at about 1 mile…..
 The FAA would like every GA  airplane equipped with ADS-B now and they are
 bending over backwards to promote  its acceptance and hold down the costs to
 the owner/operator while making the  safety benefits worthwhile. In light
 of that, UATs need not be TSO’d at the  moment where those that are
 transmitting are approved by the FCC and the  manufacturer will be required
to bring
 any in the field up to the TSO standards  when finalized.  UATs can be a  “
 portable” install (velcroed) in a certified aircraft with only a minor  
 modification approval for the installation of power along with GPS and  
 transponder-like antennas.  The FAA  has no specification for display devices
and the
 use of Bluetooth or WiFi to a  portable device (such as an iPad) is OK.  
 Remember, the FAA in on target  to have all 800 stations operating by 2013.
 WHAT CAN YOU DO  NOW?

 Why weather only doesn’t make  it Unexpected consequence is cockpit weather
 routes traffic around storms and  into dense corridors.

 Scott,  
 
 
 Do I understand correctly that ADS-B traffic information comes via a  
 ground station somewhere?    How does that actually perform when you  are in
a
 valley somewhere?
 
 
 I used to have TIS-B.  I loved it when and where it worked but there  were
 enough discrepancies + the fact that you had to have line of sight to the  
 Radar facility that I was really enthusiastic about getting my ryan 9900BX.  
 The very best thing about TIS-B is that it showed me how much traffic I  
 wasn't seeing.   However, the delay and coverage issues are real.    One
 incident I had, I was at the range limit of the Sacramento facility  when I
saw a
 blip at less than two miles 10 O'clock.   I looked up and  there was a
 mooney headed straight at me.  I dove to the right and no  sooner than he had
 passed my tail, he disappeared off the screen.   If I  had been a mile
further
 south I never would have seen him.   Another  incident: as I was going into
 Palo Alto I had several targets coming up at me.  One was 12 O'clock and
 reported as 300' below me and climbing.   I  was about to climb when I
spotted
 it already above me.  That is where the  delay was really a problem.
 
 
 Dico,
 
 
 IMO in a IVP you will be very happy to have an active system like the  
 avidyne TAS 600 or 605.   The former is only $8490 and you can install it  
 yourself.   The latter list is a little over $10,000.  (You can  probably
find it
 cheaper....or you can find someone who is gaga over ADS-B and  make them an
 offer....)   You'll find it works much more reliably,  regardless of
 geography and doesn't have the delay of going through a  ground station.
 The 600 gives you coverage up to 18,500 above which you have radar  
 separation because you will be IFR.

For the present and future, consider ADS-B.

 Hello  All,
 
 Is there a good TCAS system available for our experimental  airplanes.  I
 really like the skywatch systems with the 2 antennas..  however with the
 prices $10k - $15k, its pretty crazy high.  The Zaon  systems are a bit to
far
 on the other end of the scale and have  deadspots.  Does anyone know of other
 good systems -- or if systems for  experimental planes are being developed?
 Or perhaps were we could get  one from a written off Cirrus or something
 that had a  system?
 
 Thanks,
 
 Dico
