I agree. To determine if a flight without a transponder is legal go to 14 CFR 91.215. Also note that permission for a flight without a transponder can be obtained as described in 91.215 (d).

Islip Avionics had absolutely no issue with the certifications. If the boss at your local shop does not understand the regulations pertaining to OBAM aircraft, find another shop. Especially, since they would, if they finally elect to do the work, would take twice as long and charge twice as much! -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=247812#247812 ________________________________ Message 3 _____________________________________ Time: 07:41:50 AM PST US From: "JOHN TIPTON" Subject: Re: AeroElectric-List: Re: GRETZ heated pitot tube Just what I had in mind: but using some chrome bezels (which are available for LEDs) for easy replacement of the LEDs if needed Regards: John ----- Original Message ----- From: "Jim Berry" Sent: Thursday, June 11, 2009 11:53 PM Subject: AeroElectric-List: Re: GRETZ heated pitot tube > > John, > > I eliminated the Gretz LED's and mounting board altogether.

I have two power supplies and looking at the manual I figured that the both must go through the HE sensor (there are two wires in the photograph and there was no shunt in the box). Just to make sure I contacted AFS. They said that each power supply should be measured separately, and that the shunt was left out by mistake. They shipped it the same day. I installed the shunt for the main alt firewall forward (Z13/8), with the HE sensor for my SD-8 placed behind the panel just in front of the firewall. Haven't fired up the engine yet though.

I went with two shunts; one FWF for the main alt and another cabin-side for the SD-8. I had the main alt shunt reading negatively at first and only had to reverse the wires to the AFS unit.

I've had external power (regulated power supply) connected to one battery and I was getting negative amp indications. So, with the power supply connected to the battery and electrical consumers turned on, the shunt/HE will show a negative amperage. I am just starting the wiring on my AFS 3500 so I am probably confused, but I thought the shunt and Hall Effect were mutually exclusive. I plan to run both alternators (Z13/8) through the HE as shown on page 42 of the AF3500 System Manual V5.3. Am I missing something?
