An Eclectic Mind

Initial thoughts about my new flight following solution.

My friend, Jim, is an Idaho-based R44 pilot with a company very similar to mine. He’s a single pilot Part 135 tour and charter operator who sometimes operates over very remote terrain.

Of Flight Plans and Flight Following

One of the challenges we face as charter operators is last-minute route changes requested by paying passengers. For example, suppose the passenger books a flight from Scottsdale to Sedona. I’m required by the FAA to file a flight plan that indicates my route so that if we don’t turn up in Sedona, they’ll know which way we went and can [hopefully] find us. But at times — sometimes after the flight is already under way — the passenger might say something like, “Can you follow the course of the Verde River to Camp Verde?” This is not the most direct route and it’s not likely to be the one I planned. But what do I do? Say no?

[The right answer is yes, say no. That's the answer the FAA wants to hear. But the FAA is not paying by the hour to conduct the flight. The FAA is not going to refer its friends to a friendly, accommodating pilot.]

The problem is, if I deviate from a route and something goes wrong, the search teams may not be looking for us anywhere near where we are. So they might not find us. And sure, I have an ELT (emergency locator transmitter) in my aircraft — even though it is not required by the FAA. But how well do those really work? It certainly didn’t help them find a pilot and his co-worker when they literally disappeared on a flight between Deer Valley in North Phoenix and Sedona nearly two years ago. They’re still missing.

And then there’s Steve Fossett. Or maybe I should have said, where’s Steve Fossett. They must have spent millions by now to find him and he’s still among the missing.

Airplane pilots and pilots flying in the flatlands of the midwest can request something called flight following from the flight service station (FSS). Flight following keeps you on radar so they pretty much always know where you are. The problem with helicopters is that we fly so darn low. Even if I flew up in nose bleed territory at, say, 1500 feet above ground level (AGL), the terrain in the area I fly is too mountainous to keep me on radar. I’d have to fly much higher to stay on radar. And if I’m going to be that high, I may as well fly a plane. So flight following is not a practical solution.

The True Geek’s Solution

Jim also flies in remote and often mountainous areas. And, like me, he’s a true gadget lover — someone who likes to fiddle with electronic toys. (I think he’s lusting for a POV.1 after seeing mine.) He was based in Chelan for cherry drying season and happened to see the SPOT Messenger displayed at the local Radio Shack. He went in and checked it out. Then he did more homework. Then he bought one and told me about it.

The SPOT Satellite Messenger is a personal location device. It’s about the size of my Palm Treo and, as you can see here, bright orange so it’s easy to…well, spot.

My understanding of the unit is that it combines GPS receiver technology with satellite transmitter technology. So you turn it on and it acquires its position via GPS. You can then use one of four different features, depending on the subscription plan you choose:

• The SPOT standard service plan, which costs $99/year, includes the following three features:
  • OK sends a text message or e-mail message to the phone numbers or e-mail addresses you specify. The message, which is customizable, tells the people on the list that you’re checking in OK and provides the GPS coordinates for your position. Those coordinates include a link that, when clicked, displays your position on Google Maps.
  • Help, is similar, but it sends a customizable help message to the people you specify. The idea here is that you need help and have no other way to contact someone who can help you.
  • 911 sends your GPS coordinates to the folks at the GEOS International Emergency Response Center, who, in turn, notify the appropriate emergency authorities. This is for real, life-threatening emergencies. The Response Center folks also contact, by phone, the two people you specify to notify them of the signal.
• The tracking upgrade option, which costs another $49/year, includes live tracking, which, when activated, sends you GPS position every 10 minutes or so to the SPOT folks. This information is visible to anyone who has been given access to a Share page you configure with or without a password.

Jim went with both plans. When I bought mine on Monday, I did the same.

First Thoughts

I’ve been playing with SPOT on and off since Tuesday morning. In general, I like it and I think it’ll do the job I intend to use it for — flight following on those long cross-country flights.

After configuring message recipients, I started out by sending a few OK messages. Although the marketing material makes it seem as if those messages are instantaneous, they’re not. After pushing the OK button, the unit will try for up to 20 minutes to send your OK location via satellite uplink. It’ll send the message 3 times, but only one message is forwarded to the people on your list. For experimental purposes, I made myself one of those people. I had to wait longer than 20 minutes to receive one or two of the messages. To be fair, part of the reason for that could be my location at the time — flying between Wenatchee and Seattle in mountainous terrain. (I don’t think my cell phone was receiving very well.) The delay is satisfactory, once you realize that it’s not an instant communication.

For obvious reasons, I have not used Help or 911 yet. Let’s hope I never have to.

I did set up tracking. It took several tries to turn it on properly. The unit does not have a screen, so you have to rely on understanding the blinking lights to know what it’s doing — if anything. Twice I thought I was enabling tracking, but discovered that all I did was send OK messages. Once, tracking was on and in trying to turn it on, I really turned it off. In all cases, it was operator error. Evidently, you cannot turn on tracking during the 20-minute period in which an OK message is being sent. Since both features use the same button, it’s pretty easy to do one thing instead of the other if you don’t pay attention to how long you hold down the darn button.

My husband complained that the messages he received did not include the date and time. We later realized that it was because he was not viewing the message on his phone; he was viewing its summary. (My husband is text message challenged.)

The e-mail version of the OK message is handy because of the link it includes. Click it and go right to Google Maps with the position clearly marked. Here are two examples. In the first one, we’re flying just to the east of Snowqualmie Pass over I-90. In the second one, we’re sitting on Pad 6 at Boeing Field in Seattle. These images are at two different magnifications. All GoogleMaps features work — it’s just the location put into GoogleMaps. My personal Messages page on the FindMeSpot.com Web site displays all points with the option of displaying any combination of them on Google Maps. It also enables me to download these points to a GPX or KML format file for use with a GPS receiver or GoogleEarth.

The Share page feature, which is still in beta, was not working when I first tried it. But it’s working now — and quite well! I set up a page that does not require a password so anyone could check in and see where I was when I was traveling with SPOT tracking turned on. Apparently, it only shows the past 24 hours of activity, so it you’re checking it now and there’s nothing going on, it’s because I’m not traveling with SPOT. But here’s what it looks like right now; as you can see, I spent a lot of time exploring Walla Walla, WA today:

A few things about this feature:

• The lines between the points (which, for some reason, are not showing up in the screenshot) do not represent tracks. I was in a truck today and did stay on roads.
• If the unit did not have a clear shot of the sky, the point that should have been recorded wasn’t. This wasn’t a problem today, since I had the unit sitting on the dashboard in the broiling sun — partially to see if heat would affect it. (It didn’t.)
• Clicking a point in the list on the left side “flashes” that point in the display. You can also click other controls to get more information.
• If you leave this page open, it will automatically update. So you can watch new points appear if you’re tracking someone. Way cool.

The URL for this feature is long and impossible to remember, so I created a custom URL using TinyURL: http://www.tinyurl.com/FindMaria. I invite you to try it for yourself.

Overall

My overall opinion is very positive. It will certainly give me peace of mind while flying in some of the remote desert locations I fly in. I think it’s worth the $150 unit cost plus annual subscriptions.

Even if something goes terribly wrong out there, I want to be found.

My next challenge: getting it to send OK messages to my Twitter account. Anyone have any ideas?

Putting the tracks on a satellite image.

I had my handheld GPS (a Garmin GPSmap 60c) running while I was drying cherries and the GPS tracked my movements. Today, on a whim, I saved the tracklogs and downloaded them to my Mac. Then I brought them into Google Earth and looked at a few of the orchards.

The tracks are not very accurate. They show a zig-zag motion that appears to cross diagonally across the rows. In reality, when I reached the end of each row, I moved to the side and turned to go down another row. So rather than pointed endings and diagonal tracks, an accurate rendering would show squared off endings and parallel tracks.

But I still think it’s interesting to see how I moved over the land. Take a look and see for yourself. These are the tracks from my flights on July 4.

In this first example, I’d flown past the orchard on the south side from west to east, then circled back. I made a wide clockwise circle of the orchard to get my bearings, then came in on the south end, near a white single-wide mobile home. There was a woman there, waving happily when I arrived. She’d left the door of her house open and I blew a bunch of leaves into it. (Oops.) My track took me back and forth up the triangular orchard. Although the track makes it look as if I had a short row near the top, it’s just another inaccuracy in the track. I departed the area with a clockwise circle to the west.

Here are two others representing three dries. I went to the lower one first, passing it by on the south from west to east. I circled back, then came in on the southwest corner. I went back and forth from west to east, then broke off. It started to rain so I repositioned to the airport, which was less than a mile away. I read for a while, then got a call with a new list of orchards. I started back up and took off, returning to re-dry the lower orchard in this image again (hence the double set of track lines) after doing others a bit farther to the west. I did the upper orchard about an hour later, coming in from the northwest and departing from the southeast side back to the west.

Here’s a sloppy looking one that really wasn’t this sloppy. I did the lower orchard first, coming in from the southeast and departing out the northwest. I then went directly to the upper orchard, beginning the dry at the southwest and exiting at the northwest. The pair of diagonal lines going across the bottom of this screenshot represent overflights of the orchard on my way to or from the ones in the previous screenshot.

This is the first orchard I described in some detail in my “I Dry Cherries” post. Again, I really didn’t fly a zig-zag pattern in the main orchard. and I’m certain I flew at least two more rows (one in each direction) in the smaller orchard. But the GPS doesn’t seem to pick up all the points when it makes its tracks. The two other straight lines near the bottom right of the image are overflights to/from other orchards. That’s the Columbia River/Lake Pateros in the bottom right corner of the shot.

These are just a few of the orchards. You get the idea. Next time I fly, I’ll use my new geotagger. It can save up to 600,000 waypoints (I think) so I have a feeling the pictures it draws will be a lot more accurate. If they are, I’ll show them off here again.

We all know what a geek I can be.

I really am a first order geek.

I recently wrote a lengthy account of my “Big September Gig,” in which I spent six days flying around northeastern Arizona with a team of 15 or so Russian photographers. You can read the first part of the story here.

On Day 5, I flew from Monument Valley to Shiprock Airport to Farmington Airport, by way of the San Juan River. What I didn’t mention in my account of that flight is that I had my GPS on and running, creating a track log of the trip. (Geek alert!)

Today, I was reading messages in an aerial photography forum I follow. One of the members, in an answer to another member, mentioned a Mac OS program called GPSPhotoLinker, which can link photographs to GPS data. I figured I’d pull the data off the GPS and record the coordinates of a photo location in the photo’s EXIF tags.

I sucked the data off the GPS in Mac OS with a one-trick pony program called LoadMyTracks, which saves in both the GPX format I needed for GPSPhotoLinker and KML (Google Earth) format. I brought the file into TextWrangler, my text editor of choice, and deleted all the unnecessary data to trim down the file. Then I loaded it into GPSPhotoLinker, pointed the software to a folder containing the 18 or so photos I’d taken during the flight, and sat back to watch the results.

Disappointment. The clock on the damn camera was wrong. Since the software uses time to match coordinates with photos, there were no matches. I have to reset the clock on the camera — preferably with my computer so the time is right — and try again on another trip. But this gives me a geeky project to work on. (As if I needed another one.) When I get it all working smoothly, you’ll probably find an article about it here.

Anyway, there is a side benefit to this. I also ran the KML version of the file though Google Earth. If you haven’t wasted time with Google Earth, you’re missing out on a great time-sucking experience. Without going into a full blown description or review, I’ll just say that you can take a GPS track, like the one from my trip, and open it in Google Earth. You can then do a “tour” that follows the track just like you’re flying along with me (but at least 3000 feet higher). If you’ve got nothing better to do, give it a try.
