Adventures in GPS

As well as a chance to use my new (used) Garmin GPSMAP-296 in flight for the first time, I also got a chance to use it in auto mode to navigate around a strange city.

Before we left, I made sure I’d loaded the detail maps for Pittsburgh and surrounds into the data card. (BTW: can somebody please tell me why Garmin used a proprietary data card instead of CF or SMC? Oh yeah, so they could force you to buy it from them, right.) I also entered the addresses for Laura’s dorm and our hotel as user waypoints.

I brought along all the car stuff – the special charger adaptor with the speaker so the GPS can tell you verbally where to turn, the bean-bag holder to put it on the dashboard.

When driving, the GPS was great some times – it got us from the airport to Laura’s dorm, and from there to the hotel perfectly. But other times, it was both the cause of, and solution to, all the problems we had.

First problem – we decided after dinner Saturday night to make a run out to the airport to load the stuff that we’d gotten from Laura’s room to load it into the plane so we’d have more room in the car on Sunday. The route it gave us seemed like it took every narrow stop-sign laden low-speed-limit street through scary neighbourhoods. There wasn’t a single leg over 2 miles long.

The second problem was the way back. The route looked way better – long legs with instructions like “take the ramp to the left”. The problem was the execution – Pittsburgh has a lot of intersections where two or more streets go off on the same side in very short order. And it seems like the GPS wasn’t very good at differentiating, plus I wasn’t very good at estimating distances when it said things like “turn left in 400 feet”. After we got off course, the other problem surfaced – the accuracy wasn’t all that good. So I’d be on a road that was parallel to the one I was supposed to be on the GPS wouldn’t know until I was way off. I never saw the GPS pick up WAAS while I was on the ground, which is too bad because that’s where the extra accuracy would have really come in handly. And then I got into the high buildings, and the GPS accuracy got even worse. At one point it totally lost signal and just kept extrapolating the last direction it had seen me on, which indicated that I was driving through the middle of a park. Eventually we got back to the hotel.

Now in flight, I did pick up WAAS. So when I’m following an airway that I need to be within 4 miles of the center line, I had 5 foot accuracy available, but when I was trying to tell whether I’m on one of two parallel streets that are 30 feet apart, I had 100 feet accuracy. Such is life. I have to wonder if the inability to pick up WAAS in the car was due to using the small stick antenna instead of an external one? I’ll have to look into that.

In flight, I was using the arc mode, which isn’t like the HSI I’m used to, but it had the information I needed to follow the route, without obscuring the information below. And the information below was mostly there for information and entertainment – town, highway, and river names and the like, although it was good to keep track of where the nearest airports where. At 8,000 feet in the flat terrain of New York and Pennsylvania, the terrain page is pretty useless. The “panel” page is nifty. I can see how useful it would be in IMC to check the built in instruments, or even as an emergency backup if they fail.

First Class B experience, not as scary as I thought.

Vicki and I flew the Lance down to Pittsburgh to pick up Laura from college for the summer. It was my first experience with Class B. I was a little leery of the traffic in and out of KPIT, since it’s US Air’s hub, but Allegheny County Airport (KAGC) isn’t much further from the school and probably is a bit more GA friendly. As a side note, this is my first flight since I got my used Garmin 296.

Down, as FiledI filed a nice airway route that took me around the Class B: KROC GEE v119 MILWO v12 FURIX KAGC.

Down As ClearedBut when I called for my clearance, I guess they figured “hey, it’s a beautiful CAVU (Ceiling and Visibility Unlimited) day and he’s probably got a handheld GPS”, and so they cleared me “KROC GEE KAGC”. Almost direct the whole way. And once I took off and contacted approach, they said “proceed direct KAGC”. With the GPS, it was easy as hell, and quite smooth up at 8,000 feet. The direct route took me into the class B – actually it was while I was on the descent to Allegheny County. The Pittsburgh controller was nice and friendly, and a lot more relaxed sounding than some of the New York area controllers I’ve heard.

To As FiledFor the flight home, I filed pretty much the same thing I’d filed for the way down, but the Allegheny Four departure is a vector procedure, and CIP is one of the fixes in the depature and on v119, so I filed KAGC CIP v119 GEE KROC.

To As ClearedThe clearance I got was quite unexpected. It was KAGC ALLEGHENY FOUR EWC 050 ZORBO BAF v119 GEE KROC. It took me a bit of work to find ZORBO on the en-route chart, because it wasn’t on any airway. But after all the hassle of plotting this route on the en-route chart and putting it into the GPS, as soon as I contacted Pittsburgh departure they put me on a vector and then cleared me direct to BAF then as filed. Once again, it was very smooth up at cruising altitude (9,000 feet) but moderately turbulent down lower, both on the climb up and descent down.

All in all it was a fun trip.

Some answers on “Two Weeks To Taxi”

I wrote to Glasair about the plane I blogged about in Rants and Revelations » Now this is an intriguing idea. Here are some answers I got:

Q. When you say “two weeks to taxi”, what exactly is left before the plane is flying?

A. You will start up your engine and taxi your airplane while here. But, we recommend you do some simple steps for safety before you launch on your maiden flight. All you really need to do is a thorough safety inspection equivalent to a detailed annual inspection, weigh the airplane, complete your weight and balance calculations and then the last step is your FAA inspection, sign off to get your airworthiness certificate. Then you will start your flight test program.

We will provide you with all the detailed check lists for the final safety checks, W & B calculations and flight-testing.

Q. Do you provide familiarization training in the aircraft?

A. You will receive several hours of transition training included with the purchase of the airplane and the program.

Q. What about floats? Do you sell them as well? Can they be added there at the customer build center?

A. We do not sell floats, but we can refer you to a couple companies that make a float that will work well on the Sportsman. We cannot install floats in our program but we can put some of the attachment fittings on while you are here should you make a deal with one of the companies and they can get us the parts.

Q. I’m planning on going to Oshkosh. Is there any chance I could get a flight in a Sportsman, or just a look around one?

A. We will be at Oshkosh, and we invite you come to our booth and see the
airplane. However getting a demo flight there is not as good as getting one here at the factory. Because of the high density of traffic, we cannot allow you do to take offs and landings in that environment, and we simply do not have the time to go to another airport to get you that kind of demo flight. Additionally, we are so limited on the number of flights we can conduct, we try to limit them to people who are so close to making there decision to purchase, that it is the last thing they need to do before placing an order.

Therefore, we always recommend that prospective customers come visit us here at the factory. We are near Seattle. Not only will you be able to fly in a more relaxed atmosphere, but you will also have the opportunity to tour our facilities, and see that we are a substantial and credible company that delivers on our promises.

We are even willing to contribute toward the expense of coming to visit should you place and order with us.

I don’t know about you, but I’m convinced. Where do I mail my deposit?

(Just kidding, Vicki.)

Now this is an intriguing idea

For a long time I’ve looked at and rejected kit planes – they are a great way to get a very capable new airplane for a relatively low cost, but by the same token they’re also a hell of a lot of work and it seems like anybody I’ve talked to who has built one has spent years on it, even if it’s the only leisure time activity they did for those years (and consequently they end up with the test flight being the first time they’ve flown a plane in X years, which isn’t good). Add to that my lack of work space, and a little anxiety that I might do something wrong in a crucial and hidden part of the aircraft (like I did in the canoe I built all those years ago) and it didn’t really look like a good option for me.

Enter Glasair Aviation’s Sportsman 2+2. Here’s a plane that is equally at home on tricycle gear, tail wheel gear (and tundra tires if you want to get out to the boonies) and floats. It’s basically a 2 person plus a lot of gear plane, although they have optional back seats. The specs and reviews look very impressive. But it’s still a kit. So why the change of heart?

“Two weeks to Taxi”. That’s why. You buy the kit (and it includes everything from the engine to the tires), and you go to their “Customer Assembly Center”, and after two weeks of intensive hard work, you have a plane that you can taxi out of their hangar. I’m not sure what else is requried to fly, but the pictures in the brochure make it look so complete that it might just be a matter of painting and getting FAA approval. During that two weeks, you’re working with their factory experts there to help, and to make sure you don’t fuck it up. Plus you’re using their space, their tools, and their jigs. Not only that, but because you’ve got a better than normal chance of getting a plane built and flyable, the finance companies are more likely to want to lend you money.

Now I don’t have the money to run out tomorrow and buy this kit, so I’m sure other kit builders will be offering a similar program by the time I’m ready. But in the meantime, I’ve got this as my goal to aim at. So now my three pronged goals for the next year or two:

  • Become a more proficient pilot, especially in using the rudder.
  • Get float training.
  • Start a kit plane fund. Maybe I can start to put all my overtime money in it.

I can’t wait to talk to these guys at Oshkosh. Maybe I can cadge a test flight out of them.

Blue sky dreaming

I’ve been dreaming about flying float planes for most of my life. Especially after sore knees and hips made it increasingly hard to reach the silent lakes of my youth via canoe and hiking boot. I always remember that time on a remote lake in Algonquin Park where a park ranger dropped into our lake in a deHavilland Beaver and paddled the plane ashore. He was there to set up some toilets at a new campsite that wasn’t on our map, but he stopped over to check our permit and make sure we weren’t cutting down live trees.

Since then, I’ve often thought how cool that would be, to fly a Beaver into a lake that was only known to a few paddlers, and after the engine stopped making pinging noise as it cooled down, just listening to the loons and the breeze in the trees. I got to experience some of that on the Alaska cruise as we stood on the float of our Beaver for a few minutes.

Vicki and I were talking about it the other day, and she suggested that when I retire (or it becomes impossible to find my sort of work anywhere outside of Asia), I could fly floats as a second career. A little research shows that there are a couple of hitches to that:

  • Nobody will hire a float plane pilot without hundreds if not thousands of hours of float time.
  • Nobody (with the possible exception of Twitchells Seaplane Base in Maine, but that’s a long way to go before starting your flight) will rent you a seaplane except with one of their instructors sitting beside you.
  • Probably most importantly: float plane flying is strenous work, since the customers will expect you to do all the loading and unloading and dock work.

But before I throw out the dream entirely, I did some more research, and some more dreaming. On the dreaming side, there is Georgian Bay Airways, which as well as initial and advanced float plane training, also has a Career Bush Pilot Program where you get 50 hours of training, including 1 in their Beaver. I wish I’d known about this when I was 20 years old – they hire one or two of the students from this program to be dock hands for the summer, and you’ll get some more time flying both their Cessna 180s and Beavers. They tell me that last year’s two dock hands got an additional 50 and 80 hours flying time.

But on the more pragmatic side, I’m probably not going to be able to do that. But I could at least get prepared – I need two things: a commercial rating and a float plane that I can put a lot of hours into. So I’m looking around to see if there are any other local pilots interested in a small partnership on some sort of float plane. I can’t afford one of my own, but I might be able to swing 1/2 or 1/4 of a sufficiently old Cessna 180 or similar. These new Light Sport Aircraft are tempting, but the only LSA ambhibian is a boat-hull flying boat rather than a float plane, and none of the commerical operators seem to use flying boats so I doubt the flying time would count for much. I’m not sure if I’d even fit in a CubCrafters Super Cub on floats.

Before I get the commercial, though, I’ve got to fly a lot more. I’ve got the minumum hours for the requirements, but frankly, I consider myself a safe pilot, but not a great pilot. I have always flown “good enough” instead of “as good as I possibly could get”. I just don’t fly enough, and because of that I don’t nail my airspeeds and altitudes, I don’t use the rudder enough, and I’m not totally smooth. But I know I can do that stuff with practice. So that’s my goal this year – to get 50 or more hours of flying, and some of that time going out to do real airwork to get more than just proficient at the normal Private Pilot maneuvers before I start thinking about learning the commercial maneuvers.
