Detecting and predicting loss of control in flight

I’m currently working on detecting loss of control (LOC) on an overshoot of base to final. Using data models in X-Plane which depending on the aircraft model is known to be pretty accurate (there’s a certified commercial version suitable for flight training). Not practical to do this in an actual airplane for obvious reasons like crashing and fireballs.

Anyway, here’s a screenshot of data gathering. I’m collecting about 50 data points 10 times per second. I’m feeding this into a learning algorithm to teach it to predict the actions which may lead to an accelerated stall and/or spin. 

 

Next step is to move the pitot/AOA probe to the other wing and see what difference this makes.

I must have all of the maps

I am a somewhat reluctant weekend companion for Julie when it comes to antique and old stuff stores.

I dragged my feet for much of the morning doing my normal “don’t poke the bear routine” (why she puts up with me is anyone’s guess). Then we got to “Scavengers” which is a new place for us.

The first room was the usual, dressers with potential, desks that need to be stripped and sanded. You know, fun stuff. Just fun stuff for people who aren’t me.

Then I turn the corner and step into the very old warehouse. There are rows and rows of these drawers with names of states on the front of them. Okay, these are cool, they’d make cool storage. I wonder how much they are and open one.

Each drawer had at least two inches of US Geological Survey maps Ranging from 1965 to 1991 in many of the states in the Union.

Okay, this is more my thing. I set out on a search through the pretty disorganized collection. A quick query to the owner and he says that they bought the whole collection and they don’t print these on paper any more.

Now I have a mission.

Meanwhile, Julie is watching me run around looking for ladders, sweating a lot (crap it was hot in there), and rummaging through stacks of old paper.

Then I found what I was looking for.

Hartford Michigan (from 1981) and Coloma Michigan (from 1970).

This is a really long story to point out that THESE PLACES SOMETIMES HAVE MAPS..

I really like maps.

THESE MAPS ARE NOW MINE.

The end.

Retirement for an EA-6B

Attended a retirement for a Marine Prowler today. She’ll be permanently on display at Hickory Airport. Was great to share some memories with friends and family and hear the roar of a pair of J-52s one last time. Love love love this airplane.
