Getting K airborne again

This morning I took my wife K up for her first flight in over a year. She has her pilot's license, but with our 17 month old in the picture she has had little chance to get out to the airport.

We took the G1000 C172 and just flew around the local area. We got some pictures of the new house we expect to close on tomorrow as well as other local landmarks.

I was in the left seat and K was in the right seat. When it was her time to fly I put the G1000 in reversionary mode - to give her her own complete set of instruments. That's a very cool feature for that type of situation. However, after flying in rev mode for 15 minutes or so, I pushed the red button to go back to normal mode and - guess what - I found a bug in the G1000. A picture describes it best:


Basically the PFD went back to normal operation but the MFD only partially recovered. The bottom soft keys remained in "rev" mode and the moving map would not come up. The ability to change "pages" never came back either.

After simply waiting a few minutes to see if it just needed time to fix itself, I then tried swapping into and out of rev mode a few times to see if that would help. It would always go into rev mode just fine but kept showing the same problem when coming out.

So I pulled out the pilot's guide for the G1000. That book had ZERO troubleshooting info, so it was no good to me.

After examining the circuit breaker panel diagram for a bit, I decided I could disable the autopilot and cycle the power on the #2 avionics bus to reboot the MFD. Doing that fixed the problem. At least rev mode kept working properly. :)

K's post about the flight is here.

I can certainly empathize with K's position. After long periods away from flying, one tends to get rusty. But, after a quick review you tend to settle down. Keep flying.

Updating data on the Garmin Perspective system

Image
After changing from the Avidyne system to the Cirrus Perspective (G1000) system, I had to relearn an important part of owning an airplane: how to update all the data the systems use. There's even more data in the Perspective, including AOPA directory data and more charts. In this walkthrough, I make use of the Jeppesen app for Apple OS X: JDM .  It has worked well for me, though I did need to call Jeppesen when I first set this up to get my subscriptions fixed up.  They gave great customer support when I did. The process starts (optionally) by hooking up a ground power unit (GPU).  In the case of the Cirrus, you can certainly do this without it, but I tend to hook it up just to be sure.  The systems draw about 8-10amps while updating, but you won't generally have the power on for long.  One tip I've read: power up the GPU before plugging it into the plane, at least for the one I bought.  That saves the plane from seeing any power spikes that might have occurred when t

G1000 transistion training - emergencies - final flight

Image
For the final flight in my G1000 transition course we focused on failure scenarios. Not the "engine goes POOF" kind but the avionics kind. Normal situation This picture shows what the 2 Garmin screens show in a normal (non failure) situation. You can see we have 2 screens - the left PFD focusing on flight performance (airspeed, heading, attitude, altitude) and the right screen (MFD) focusing on engine data, mapping, checklists, and everything else. Failed PFD screen In this scenario the screen that is right in front of you (the PFD) has failed. This basically means the screen has gone dark. We simulate that by dimming the screen down to 0% brightness. After darkening the PFD we shot a GPS approach into Rock Hill. When this failure has occured you shift the G1000 into Reversionary mode. That means the info that is normally split across 2 screens is now merged into 1. It actually duplicates the same data on both screens, but since the PFD screen is no longer functioning

A-10C Standby Compass - Sun Shade

Image
 One of the final items to add to this instrument build (besides the text covers for the lower LEDs) was the sun shade for the AR LED box.  I made this out of thin aluminum sheets , cutting it from a template using some metal sheers .    My template was created by tracing some of the actual artwork from the DCS sim, and then scaling it to the proper size. It turned out ok, not perfect but pretty good.  Primed and painted it and then installed it using 2 of the 4 holes that were already on the LED box 3D print.  I used some heat inserts in those holes to give the screws something to bite, but the holes are really too big for my inserts so had to use some glue to help out.
