Standby Compass - first steps

Started on a standby compass today.  Printed out the parts from TWP (Warthog Proj) and ordered electronics he mentioned in the video.  Did the same finishing of the 3d prints as he did - started the sanding.  

Mounted the electric dewalt sander in the big vice upside down to act as a bench sander.  Sanded and rinsed them in water to remove the dust.  Will use spray filler and then paint to get them looking better.

Used some of the black M3 screws to mount some of the parts.  

Learned a bit about backlighting, TWP has some good info on that.  

Ordered computer PSU breakout boards to get to power coming off that.  Also ordered 2 PWM LED dimmers to connect to that breakout.  

3d prints:

I like the organic/tree supports, but make sure you orient the part such that the top of the tree is minimal cross section.  If the tree ends up "spreading out" at the top it is near impossible to break loose - you want a minimal connection at the top where it supports the print.  Flexing them with pliers tends to break them loose fairly well.

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

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).

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
