1) Adjust pulses / rev. Page 7-47 of install manual. 2) If it doesn't work with another harness, then the only other thing to try is unplugging the D37 and D25 sensor harnesses. If that fixes it, you have a short to ground or power somewhere. If not, then the EMS module needs repair here. 3)...

You must connect both displays.

We did re-run the test from Tuesday as well. Back on Wednesday, we said: As designers of the D10A, we knew that checking at 28 and 30 meant that voltages in-between would also be correct. However, for completeness, we went back and checked at every 10th at 28 volts. In every case the voltage...

Each D10A has its own voltage calibration, so doing this on a specific unit doesn't show what all units will do. Yesterday, we tested 4 random units at 26, 27, 28, and 30 volts, and at voltages in-between, and they were all within 0.2 volts at all those voltages and throughout the range. We...

So a few notes/questions: 1) Technically, a 4-way GPS average isn't accurate. It's a bit non-intuitive, but the correct way is a triangle with some math. There's a great thread on VAF about this, with spreadsheets and such: http://www.vansairforce.com/community/showthread.php?t=59870 2) GPS...

Turning on both modes is normal. 99% of the time that the autopilot is used across the fleet, the pilot wants both roll and pitch engaged, so doing this saves button presses overall. It's also the way basically every integrated autopilot works. In fact, most autopilots won't allow only one axis...

Tom, Since this is an RV-12, I assume you loaded the software from Vans? If so, this resets your settings to the way Vans has the RV-12 set up. They don't show Tach time because Rotax doesn't allow Tach time for any maintenance on the Rotax 912 engine, so it's considered kind of a useless thing...

Serious question: If we greyed out the NAV SRC in the AP menu, wouldn't you have written us asking why it was unavailable?

About 30 seconds. If you have the backup battery, you can just press button #1 to turn it on, you don't have to use the master.

The AoA system senses the difference between the pitot and the AoA. Not just the AoA. The pressure due to aircraft velocity is removed because it's common to both ports, and only the AoA pressure remains which is independent of speed. The Pitot port is specifically designed to be insensitive to...

There are already at least 5 ways to get an ID into the radio: 1) The NRST list on the radio. This goes to 75 miles out. Generally, this is about as far out as you can use a radio, so we feel it's a pretty reasonable distance. We can't put the whole database in the radio as the list is too big...

The MAP sensor is designed to be FWF. We have planes with thousands of hours FWF with no problems.

Just because you see the DTO on the map doesn't mean the HSI is on a source. When the G-Meter is up, you can't see or tell what your HSI source is. So it's really not possible to know or tell what the config is with the G-Meter up. The only bug would be if you turned off the G-Meter and the HSI...

The only issue you'll have is if you have something plugged into both D9 connectors on the back. If so, you need to plug these into one another, but they are the same gender so you need a M-M connector. The D37 can just be disconnected and left free.

Yes, as shown in the install manual, trim power comes from pin 9 and this needs current protection. If you disconnect power from this, the trim will not run. Be aware that this means you will have NO trim control, not just lack of auto trim, so you'll get to fly your first flight with no trim...

No, this cannot detect a stuck "open". One of your servo disconnect wires is shorted to ground.

Yes. Handling the dual bands of the 472 requires new firmware on the screens.

Likey you only have audio hook to one screen, and skyview requires both screens be hooked up. Run the audio test on both screens. If it only works on one, this is the problem.

In SkyView, we'd probably recommend thermocouples for additional engine temperature compartment measurements. There are plenty of these inputs, thermocouples are cheap, and they work above 400F. A carb temp sensor is really only designed for up to about 150F. Since you have an D120, you don't...

#1) Yes, MAP MENU -> MAP MODE -> KNOB LOCATION. Set this to LEFT. (Page 7-70 in Classic/Touch User Guide for more info #2) Yes, you can choose what is in each info item, and if they are active. MAP MENU -> MAP INFO ITEMS. You can't completely drag them like the EMS widgets, but pretty close...
