Cross-country in the sweeps: Getting there is half the funCross-country in the sweeps: Getting there is half the fun

Getting to Oshkosh, Wis., from the Mid-Atlantic by Cirrus requires answering one central question: whether to fly over or around Lake Michigan?

Flying over the lake means being out of gliding range of either shore for about 20 minutes, but it also results in a shorter total distance, an efficient nonstop flight, and a mercifully brief period in Chicago Center’s busy airspace. Staying over land requires circumnavigating Chicago to the south and west, sometimes way south and way west, a fuel stop, and the associated descent, hot start, full-power climb, etc.

This year’s trip to Oshkosh presented an especially challenging set of circumstances that, in the end, illustrated some of the AOPA 2009 Let’s Go Flying Sweepstakes Cirrus SR22’s impressive capabilities.

For starters, fellow traveler Warren Morningstar and I would have to confront 30-knot headwinds over most of the route. A menacing line of thunderstorms would require a significant deviation north or south, and if we climbed near the airplane’s 17,000-foot service ceiling to extend our range, we’d be at, or close to the freezing level. And even though there were only two of us aboard, we’d be carrying so much gear for the show that the airplane would be near its 3,400-pound gross weight limit.

Morningstar took the left seat and handled the takeoff and climb like a pro, even though it was his first time flying an SR22. He hand flew the airplane to 12,000 feet and configured for a lean-of-peak cruise (164 KTAS at 12.4 gph). The headwind made its presence felt right away, but if we could continue our relatively straight line, we’d get to the big show with more than two hours of fuel remaining.

That’s when the XM Weather depiction on the Avidyne display gave us the bad news about the storm system ahead. A cold front in the Ohio Valley was spawning a big line of storms that stretched from southern Indiana well into central Michigan. The south edge of the front was thin but violent with red and purple radar echoes and numerous lightning strikes. The north side was wider, but the radar showed only greens and yellows representing light and moderate rain showers.

We had brought a pair of inflatable life preservers in anticipation of crossing Lake Michigan. Deviating around the approaching weather system north of Cleveland, Ohio, meant they’d be doubly useful as we’d cross Lake Erie as well.

Morningstar, who grew up in Utah, said he didn’t mind flying over the big bodies of water.

“At least it’s summer,” he said. “The water down there’s probably about as warm as it ever gets.”

We entered IMC and continuous light chop near Cleveland, and a nearby airliner reported light rime ice at 14,000 feet. The OAT indicators (two of them) in the Let’s Go Flying SR22 weren’t in complete agreement. The one on the PFD (which derives its information from a probe on the wing) indicated the air around us was within two degrees of freezing. The one on the MFD (which gets its data from a probe on the engine cowl) showed eight degrees above.

“I wonder which one we should believe,” Morningstar said.

We continued north all the way into Canada before a wide gap allowed a west-bound turn toward Muskegon, Mich. We stayed at 12,000 feet but soon began collecting traces of rime ice. The airplane’s TKS system removed the traces quickly from most of the wings and tail, but small amounts remained on the wing roots and tips.

The OAT on the PFD registered freezing while the one on the MFD registered six degrees above.

“I guess we know which one to believe now,” Morningstar quipped. (The OAT probe on the cowling was likely getting some heat from the engine.)

We climbed to 14,000 feet and pushed our way westward in blue sky and smooth air. The higher altitude allowed us to reduce fuel consumption to 10 gph, and ground speed was virtually unchanged. We had sufficient fuel reserves to make our destination under normal conditions. But the often swarming VFR arrival into Oshkosh isn’t normal, and we didn’t want to enter the melee with anything less than two hours of fuel in the tanks.

The clouds disappeared over western Michigan allowing a clear view of the blue waters of Lake Michigan. We were on an IFR flight plan for Sheboygan on Wisconsin’s eastern shore (Oshkosh wasn’t accepting IFR arrivals), so we planned to cancel when we arrived overhead and then continue VFR to the big show.

Oshkosh had wisely put its ATIS information on an extraordinarily powerful transmitter and we were able to pick up the information more than 120 miles away. The winds were out of the west at 16 gusting to 23 knots, and the ceiling was 4,600 broken.

Morningstar clicked off the autopilot and started a long descent over the lake. Shortly after reaching the Wisconsin shoreline, we ducked under a layer of cumulus clouds and bounced along toward Ripon and the well-known Fisk Arrival.

It had been several years since I last flew to Ripon, joined the conga line, and followed the railroad tracks to Fisk, then Oshkosh. But the well-written and illustrated Oshkosh notam made the process straightforward and easy to understand.

Morningstar took out his video camera to record the event, and I took over the flying duties.

Given the strong west winds and relatively light traffic (for Oshkosh, anyway), I assumed we’d be landing on Runway 27, and I’d pre-programmed the radio frequencies accordingly. As we approached Fisk, however, the Cherokee Six in front of us was assigned Runway 36, and we got the same instruction.

One frequency change brought us to Oshkosh Tower South, and we were told to land on the “yellow dot” about half way down the runway.

The Let’s Go Flying SR22 and its highly authoritative rudder pushed back against the crosswind and held the centerline. Moments later, Oshkosh volunteers directed us to AeroShell Square where we shut down the engine. The Let’s Go Flying SR22 still had 24.1 gallons of fuel remaining after 4.8 hours in the air.

The ground crew tugged the airplane to AOPA’s Big Yellow Tent for its weeklong display.

Visitors to the AOPA tent at AirVenture 2009 enjoy looking into the Let's Go Flying Cirrus SR22.We were pleased to open the airplane to the highly knowledgeable and airplane savvy visitors that Oshkosh attracts, and glad to answer questions about the many modifications that have been made to the Let’s Go Flying SR22 in recent weeks. The Forward Vision EVS-100 infrared camera system and its pop-up display screen drew the most curiosity, and AOPA members also wanted to know about the AmSafe airbag seatbelts and S-Tec roll autopilot roll servos.

We didn’t intend to add so many new products and upgrades to what was already a fantastic airplane when philanthropist J. Lloyd Huck donated it in late 2008. But each modification has improved the airplane’s already impressive performance and utility.

And when you see it at AOPA Aviation Summit in Tampa, Fla., Nov. 5 through 7, the Let’s Go Flying SR22 is likely to be sporting a few more improvements.

Old habits are hard to break.
