Everything we do in life carries risk. An undesired outcome often is influenced by factors we cant control-someone running a stop sign, for example, or a perfectly good engine deciding to fail. But many other risks of a specific activity can be anticipated. Its why we wear a helmet when riding a bicycle, or earn our instrument rating if we regularly fly an airplane beyond the traffic pattern. Serving as a pilot in command offers many ways to increase our risks, but it also brings opportunities to mitigate them.
After noting that five incidents of aircraft uncommanded roll events with the ATLAS activated have been reported to EASA and the FAA, the U.S. agency on May 24 issued an airworthiness directive (AD) grounding Cessna CitationJet 525, 525A and 525B models equipped with Tamarack active load alleviation system (ATLAS) winglets. The action is related to an EASA AD and is mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product.
I used to ground myself when I saw a forecast of thunderstorm weather. I had an immediate visceral response rooted in memories of growing up in Kansas, seeing vast tornado-spawning squall lines, their blue-green tint indicating they were pregnant with hail. At age 11, I watched a barn across the road explode in one of those storms, flying in pieces across the fields, followed by a barrage of baseball-sized hail. Surely you cant fly when convective weather and thunderstorms are nearby or on the way, can you? Well, Dorothy, sometimes you can. You just need to know what to look for and what to avoid.
And like every other technology, autopilots have their limitations. For one, they have to be set up correctly-along with the navigation equipment-to reliably follow a heading and descend along a glidepath. Details like when to take over from the autopilot, how you might handle an equipment failure-if you notice it-and even whether to let Otto fly the missed approach or do it yourself need to be worked out ahead of time. Thats the short version of why we might want to consider hand-flying the approach. Lets expand on them.
Receiving inspection of new air filters (p/n P107336) revealed three out of four had a defective sealing surface, causing the sealing/mating surface to crack and crumble. This defective sealing surface could potentially enter the engine. The defective filters sealing surface has a light-gray color while the replacement filters we received, inspected and found to be in serviceable condition had a dark gray, almost black sealing surface. Suspect that the defective filters had improper material on the sealing surface or were improperly cured.
Normally, I might have panicked, but with my experienced copilot at my side, I stayed calm. We talked through our options and decisions along as I continued to fly the plane. I began a series of small adjustments to the throttle and mixture to see how the engine responded. We quickly discovered these changes only made matters worse, so we left the settings as is. My buddy reminded me to stay high-altitude is our friend-and we looked for landing spots in case things deteriorated.
One way to deal with this torrent of poorly presented information is to call Flight Service, ask for an abbreviated briefing and query the briefer about Notams for your proposed flight, and especially if theres any new FDC Notam affecting the airspace or procedures you anticipate. Listen to the briefer; there might be some nuggets you didnt know about. And at least youll be on the record when FAAs enforcement apparatus asks you about a TFR bust. -J.B.
Knowing of the low overcast, if that pilots autopilot had this auto-capture feature, his motivation would have been to ease his workload and obviate spatial disorientation during transition into the clag. The effect of his action would have been to capture the airport elevation as target altitude. The TruTrak, at least, takes a few seconds to process and implement settings, so that the airplane would be expected to do exactly what it did: ascend into the clouds and a few seconds later return to the preset target altitude of the runway.
According to the assumptions the FAA used in its forecasting, the U.S. economy is projected to grow during the period, but more slowly than any other region in the world. Real gross domestic product (GDP) growth in the U.S. for the 20-year period is forecast at 1.8 percent while worldwide GDP growth is estimated at 2.8 percent. Only Europe, Africa and the Middle East are projected to see similar GDP growth, estimated to be 1.9 percent. The Asia/Pacific region leads the pack, with 4.0 percent growth projected over the next 20 years.

When we first learned of the breadth of the detonation problem, we contacted XP-400 engine owners and paid to have them ship their engines to our facility for evaluation, Superiors Bill Ross told sister publication Kitplanes. We disassembled, inspected and tested the key components in each engine, he said, but even after adjusting the ignition timing specification, the results were still unsatisfactory. In response, the company decided to ground affected engines and create a buyback program.
I recently had the chance to chat with a long-time friend and pilot about some issues he had with an instructor while working through a flight review. The friend was concerned about the instructors critique of his flying, which included comments like, I didnt expect you to do that, and I would have done it differently. The friend wasnt necessarily complaining about the critique itself but the after-the-fact manner in which it was supplied. Ultimately, it undermined his confidence and he chose not to fly with that instructor again, taking his chances with someone different.
