A10-C Standby Compass: Final Setup


Got everything soldered together (after likely damaging one EasyDriver and moving to a backup) and squeezed it into the case.  At first I thought the compass wheel was much too high but then I realized the front bezel was installed upside down.

Used an Exacto knife to cut a piece of acrylic for the front glass and put a small vertical sticker on it to act as the reference line.  Not super pretty but works ok until I can cut with a laser instead (maybe an xTool).

Getting everything to fit was trickier than I expected, but it all worked out without too much rework required.  I used some 5.5mm x 2.1mm plugs for the 12v power plugs (tip/center was positive).  

For the aerial refueling LEDs I used some more LEDs that have resistors built-in.  They are made for 12v so will likely bit a little dim since I am powering them off the digital out 5v pins from the Nano.  Don't have a way to make the lens for those yet so will wait to see if that is the case.  So far so good though!

Since I had about 8 wires routed out of the compass box, once it was all setup, I lost track of which wire was which.  Had to pull the guts out again and zip tie groups of wires before reinstalling things.  Haven't found a good way to label these tiny 22AWG wires yet.

Designed a 3D printed back cover for the AR LEDs (in Fusion 360).

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

Hiking to Rocky Peak in Steamboat Springs

Image
Did a great hike today that is not in the commonly used hiking apps.  The trail is generally easy to see, though there were times that we lost it.  There are plenty of bushes and undergrowth draping over the trail, so bring long pants. Leg gaiters might be nice too, just to protect your legs a bit. Many parts of the trail are actually drainage ditches.   Here's a KML file from our trip down - we followed the trail much better after learning what to avoid on the way up. We went right after a thunderstorm had come through the previous night, so got pretty soaked due to the plants being wet.   Found the path to the top and saw 2 moose along the way - gorgeous views for the entire trek.  2 miles to get to the top from the parking near the hot springs with about 1800' of elevation gain.  Certainly not a beginner's hiking trail, but not a problem for those with some experience (and lungs that are used to the altitude).
