Just out of curiosity, how do you have your HXr and Mini interfaced to your navigation sources? I have similar GRT equipment - HX and Mini-X, and am quite curious to know how you have things hooked up.

Thanks!

The challenging part was dealing with only 3 serial ports on the Mini. I set up three relays tied to a reversion switch. The first has the DU interlink in NC and a connection to my magnetometer in NO position. The second has a connection bridged to the AP links on the HX, allowing the bridging of the MINI and requiring the HX to be turned off (I will be changing this, as I feel better with a more traditional SPDT connection for this on the AP Tx side). The third relay bridges the nav input to my two radios (a DPDT switch chooses which radio will be fed to the Mini input NAV or GPS). I also connect the dedicated Trig Transx connection going directly to the Trig format interface (this has to be left off in software or it takes over control of the transx from HX).

I have some concerns over not wanting to be changing settings if in the soup if I lose the HX and I am taking out my SL30 and KLN-90 and replacing with a 430. The 430 can only provide serial-based CDI output for GPS-horizontal and I don't plan on adding ARINC to the Mini to get VLOC CDI data. My new plan is to connect a dedicated serial port from the 430 to the mini (assuming that the 430 won't hiccup from getting air data from 2 different sources - data should be the same courtesy of the display interlink). I will run the AP Tx feed to the common on a SPDT switch with the NC to the HX and the NO to the Mini. Rx is bridged as it is a multi-cast protocol. This will allow me to simply change which device controls the servos. I will leave the Display interlink in place and give up on the magnetometer, as I don't feel that I really need magnetic heading in the case of a failed EFIS. If I declare a loss of primary navigation, I am sure that ATC would accommodate me using track instead of heading. I will probably run the trig output from the Mini to a switch in the NO position. I may skip it. I just haven't decided how important it would be to have control over the Transponder in an EFIS loss. Certainly desirable, but not sure how critical.

I will still get ILS and V & H GPS data to the Mini if the AHRS fails but the DU is still working. The CDI data is passed over the DU interlink.

I bought a 5 Ah powersonc battery that I charge through a 20A GP diode (drops about .4 volts and fits into the float voltage range). The battery connection feed the single power input to the Mini. This eliminated a B/U switch.

That first solo flight into an overcast is almost like the very first time a pilot solos. Once you penetrate the cloud deck, you think well I 'm here now I got to get myself back down, by myself. :-0

Congratulations
 
Larry:
A few suggestions to aid in your new and never-ending journey...

File instruments on every cross country flight you take, even in CAVU weather and even if your destination doesn't have a published approach. The more you work with "the system", the more comfortable you'll become with it.

Practice often. Even if you fly every week in the Great Lakes area, you'll find that most IFR flying involves climbing thru layers and there will be very few times you'll actually do a full approach. Practicing is a great excuse to fly more.

Try to do as much flying as possible by hand. The auto pilot is your friend, but it can become your enemy if it turns into a necessary crutch.

Finally, relax and have fun. The more you practice, the more relaxed you'll become in actual conditions - even your passengers will notice this.

Terry, CFI

Congrats....cant wait to do the same thing

Congratulations, Larry!

It was almost one year ago that I took the instrument checkride in the RV9A. It takes a lot of anxiety about weather out of cross country trips. As others have said, practice a lot and fly in the system every chance you get. Welcome!

It is due to arrive here tomorrow. I have ordered all of misc parts and hope to get it installed this weekend.

Thanks for all of the advice and ideas on best managing and further developing this skill. I appreciate it.

Huzzah!
 
Larry,
Having taken the same written and checkride less than two years ago, I get how much of a milestone this is to you. How much a feeling of accomplishment.
Congratulations, Sir!
v/r,

Congrats Larry!! The instrument is as tough one to get!
