More fun on skis

Plane: Cub, 85 hp 
Instructor: Emerson
Route: 40I-2OH9-40I
Weather: Scattered clouds, 30 degrees, wind 250 degrees at 14 knots

Due to the recent cold temperatures, much of our Christmas and just-after-Christmas snow remains on the ground. This means Stewart has had the big Cub on skis for over a week. That equates to me being overdue for some stick time in the coolest winter flying machine around!

Given that we only saw snow once last winter and the skis never found their way onto the Cub, I certainly didn't want to miss out this season. Although I have a feeling we're going to see more snow than a year ago, you never know. Doesn't feel like it, but the last (and only) time I flew the J-3 on skis was nearly three years ago.

Yet another awesome thing offered at Stewart - a Cub on skis!

It took a minute to pull the engine through but Emerson hopped on board once it was humming and I taxied towards the runway. No feet on the brakes since the brake lines are capped when the skis are attached; you can actually mess them up if you smash on the pedals! The snow is pretty packed at this point and we ended up making quite a large circle, down to the less-packed snow and back, in order to do a 360 before takeoff.

There was a screaming wind by the time I got to the airport (14+ knots) but thankfully it was almost directly down the runway. Between that and the icy surface, this was a perfect day to illustrate the importance of proper control positions while taxiing. The rudder can be less than effective on ice/snow (big skis sliding vs. little wheel digging into the snow) but it was actually possible to turn the plane faster by utilizing the aileron into the wind technique. Basically, I was able to use the aileron to help weathervane the plane on the skis. Handy!

Flying-wise, it's really not all that different than when the wheels are on. Slight forward stick, then gentle back pressure until you gain speed and the plane lifts itself off the ground in the familiar three-point attitude. Landing is pretty similar as well, though I always felt like I was about six inches higher when I flared. But that's the beauty of snow + skis; even the not-so-great landings were quite soft and cushioney. As you may imagine, taxiing requires more throttle than usual, around 1500 RPM. You also have to slow down more to turn in order to let the skis grab into the snow and not slide all over the place.

From 30 MPH on takeoff/landing to 90 MPH on downwind - it was windy!

We landed a few times at Stewart, first on the runway and then on the north taxiway. The runway's quite compacted after a week of skis sliding on top but the taxiway was covered in fresh, untouched snow. Judging by our tracks, we landed in about 100 feet on the fresh stuff. Emerson then had me fly over to the gliderport and we landed there twice. Finally, we headed back to Stewart and called it an afternoon.

You really do pick up the knack of the skis quite quickly. They're not harder per se, just different, especially if you're used to tailwheel flying. As if to follow the general taildragger mantra, the only real differences are on the ground. Regardless, it's still a hoot and I'm quite happy to have been able to squeeze it in at least once this winter.

And hey, I'm already ahead of 2012, when I didn't hop into the left - or back - seat until April!

Stewart in the snow

I'm currently halfway around the world but this seemed like a fitting time to finally post these photos. From what I hear, we're about to get dumped on with snow back at home. I actually took these last February after I flew the Cub on skis. You just can't beat the vintage feel of Red Stewart Airfield with a J-3 buzzing around the pattern on a crisp winter afternoon.





The lack of recent updates is a direct result of the halfway-around-the-world-ness. Being in Japan and Korea tends to keep one grounded - aside from the loooong commercial flights required to get here, of course. I'll be back later this week so hopefully I can get back behind the controls before too long!

Going skiing in the Cub

Plane: Cub, 85 hp + Skis
Instructor: Emerson
Route: 40I-2OH9-40I
Weather: Clear, 23 degrees, wind 260 degrees at 6 knots

If there's one good thing to come of the crazy amount of snow on the ground here in Southwest Ohio, it's that Stewart has the Cub on skis. Last year our one big snowfall melted so quickly that I never had a chance to fly it in this configuration. I had today off work since we're headed up to Michigan for a wedding Gina's in and took the opportunity to head down to Waynesville and go flying first thing this morning.

THIS is what winter flying is all about!

Emerson cleaned the frost off the wings and windshield while I completed the preflight. Then I hopped in and he propped using the cold-start procedures. He taxied us over to the fuel pump and I waded through the 2 foot drifts (they were up to my knees or higher) to fill our tank full of 100LL. Engine running again, I ran through my full CIGAR checklist sans run-up before taxiing towards the runway.

He had instructed me that we would almost need full throttle at times to move through the heavy snow. As I brought the power up and wiggled the rudders back and forth to break the skis loose, we started to move away from the fuel pump. There's a lot less friction when you move over top of existing ski tracks in the snow, so you have to constantly adjust the throttle to keep moving. Just as in soft field procedures, you never want to stop moving of you run the risk of getting stuck.

Stewart - the only way to get in or out is on skis

Silos and houses off the end of Runway 26 at Stewart


I made a big left circle to ensure the pattern was clear and then rolled onto the runway. Full power and we started to move. As we picked up a little speed, the wings began to develop lift and you could feel the weight come off the skis. I held in back pressure to keep the tail close to the ground as you do in a soft field takeoff in the Cub. Before I knew it, we had smoothly lifted off the snow and were quickly climbing and I snapped into usual pattern mode. Turn crosswind at 1,500 feet, downwind, throttle back and level at 1,800 feet (though I ended up at 1,900 most of the time today) on downwind.

Abeam the numbers I pulled the carb heat and slowly brought the throttle back to 1,500 RPM to ensure I didn't shock cool the engine. On final I could tell I was a little high and I brought the throttle almost to idle to bleed some altitude. About 20 feet above the runway I added in a couple hundred RPM (soft field technique) and made slight corrections all the way to the ground until we touched very softly. Emerson said "good job" and I have to admit I was quite proud of the landing, too.

I made another two circuits around the pattern at Stewart, each time departing with a very smooth takeoff and a very cushioned landing where you could just feel the skis kiss the snow. Based on this flight and my last one in the 150, I'm starting to think having Emerson along is my good luck recipe! After the third landing at Stewart, he asked if I wanted to go over to the gliderport for a few landings. They're more protected by trees and the snow is deeper so I said, "sure, let's go!"

Caesar Creek Gliderport on downwind to Runway 27

It's only about 3 miles away, so I was almost in their pattern by the time I leveled off after takeoff. On downwind for Runway 27, I could see just a few ski tracks on their otherwise very smooth and snowy field. There's some large high-tension lines about 1/2 mile out on final so I ended up a little high and floated about 500 feet down the runway before touching down. It was such a smooth landing that you could actually feel the back of the skis hit first and then settle down as the weight of the plane brought them fully into contact with the snow.

Some beautiful houses nestled in the woods near the river

Taxiing in the heavier snow, I had to keep the throttle around 2,000 RPM most of the time to stay in motion. On takeoff you could actually feel the lift build on the wing as our acceleration was slow at first, then picked up quickly as the weight came off the skis - very cool. I made two trips around the pattern here as well, with an extremely smooth takeoff and two very, very smooth landings. The soft snow really cushioned the landings (it's like landing on cotton almost) but I was also doing a great job managing throttle and stick for nearly zero-descent touchdowns.

I asked Emerson to fly us back to Stewart after my third takeoff at the gliderport so I could take a few photos on the way home, which I've embedded throughout this post. He kept us around 500 feet AGL and I really enjoyed seeing all the snow from such a great vantage point. I took the controls again on downwind and brought us back for another smooth landing.

Most of you know how much I love the Cub in general and how much I rave about flying around in warm weather with the door open. Well, that's all awesome but this whole skis business is the next level of awesome. Today was an absolute blast and it introduced me to yet another wonderful part of the J-3's personality. Seriously, it's nearly impossible to imagine more fun per dollar ($62/hr at Stewart) available in an airplane I can rent!
