Moving forward with New Generation System

[rogersmart]

I am building an RV-8A and planning on using the new generation system, hurry up!  I have some questions for panel planning and placement of modules.

1.  I would like to know if I got this right.  For a system with 10” screen, autopilot, moving map and EMS, the modules will be the Display, EMS module mounted remotely (inside the firewall), AHRS or ADAHRS mounted remotely, a GPS antenna/receiver and servos mounted in proper locations.  Is this correct?

2.  Is the AHRS or ADAHRS module going to include magnetic heading internally or require an external module like the EDC-D10?  Will there be a restriction on mounting adjacent to steel parts, strobe power supply, strobe wiring or adjacent to the autopilot servos.  Can it be mounted behind the panel near a radio?  What is a safe distance from these items.  Please give some guidance.

3.  Will EMS, ADAHRS and GPS modules be powered from the Display and use battery backup if necessary.  It appears the servos will are powered separately.

4.  Will wiring between the modules be 4 wire, 2 DSAB and 2 power?  What type of wire will be used?, shielded, twisted pair?  Will there be pre-made harness for connecting modules?

5.  I see there is no tray, can the the display be removed completely by removing the 6 screws shown and unplugging some connectors?  (how many connectors and what type?)  Would this leave a big hole for access behind the panel, ie no mounting parts.

I have received a SV32 pitch servo and will be installing it as the first component.  I plan to order other available items as I progress such as the engine kit and roll servo,   Please share information as it becomes available so I can plan better and more accurately as our project moves forward and your new generation product plans become final.

Yes.

At least at first, the ADAHRS will include the magnetometer internally. The whole thing will be really small, similar to the size of the current EDC-D10A.

Generally, you want to be at least 1-2 feet away from ferrous metal and power.

3. Will EMS, ADAHRS and GPS modules be powered from the Display and use battery backup if necessary. It appears the servos will are powered separately.

Yes. The major system components will be powered via a novell wiring scheme that will have redundant DSAB (data) and power connections (this applies to the "major" system modules like the EMS and EFIS, but not necessarily the smaller things like the GPS receiver/antenna.

4. Will wiring between the modules be 4 wire, 2 DSAB and 2 power? What type of wire will be used?, shielded, twisted pair? Will there be pre-made harness for connecting modules?

There will actually end up being about double that, and we are planning on pre-made harnesses for this particular connection.

5. I see there is no tray, can the the display be removed completely by removing the 6 screws shown and unplugging some connectors? (how many connectors and what type?) Would this leave a big hole for access behind the panel, ie no mounting parts.

Yes;connector scheme to be announced (it will be different from current products);yes

Panel Planning questions for NextGen Power connections.  I looked at the FD180 installatiion since this product has both flight and Engine instrumentation.  I see thee external power sources, Primary, Keep Alive and External Backup.  I also understand the nextgen engine and ahrs modules receive power from the screen.

Will external power connections for the nextgen be similar to the three FD180 sources?  
Should primary power be switched with the master switch and main bus?
Since I need engine instrumentation during startup, can the nextgen system be left on during crank without potential damage?  
Will nextgen engine instruments read correctly considering the voltage drop during cranking?

There is only one power input into the next system. No keep alive or backup power.

This can be on during engine crank.

The system can detect things during engine crank with no internal issues, but the engine ground having 300A passing through it might mess with some sensors somewhat. Most of our customers are only concerned with engine parameters right after the engine catches, not during the actual crank phase.

When you say "but the engine ground having 300A passing through it might mess with some sensors somewhat", are you saying the output of the sensors may not be reliable while cranking or are you saying with the system on, the sensors could be damaged while cranking.

Also what will the recommended power source be:
Main bus power switched on during cranking.
Avionics bus power switched on after cranking.
A dedicated switch or other configuration.

 

[dynonsupport]

The sensor readings will be unreliable during cranking. No damage will occur. The vast majority of our current EMS customers have the EMS on during engine crank with no issues and this will be no different.

I'd suggest that the system come on with master power. You might want a separate switch or circuit breaker to kill power to it if ever needed, but this would not be used in normal operation.
