By the time student pilots near the practical exam, they’ve usually got a pretty good idea of how and why to calculate density altitude (DA). If they’re lucky, they’ve even done some high-altitude takeoffs with an instructor, or at least simulated DA’s effects by using much-less-than-full power settings on a few takeoffs. Those tables and graphs overlook an important characteristic of the air in which we’re trying to fly: its humidity. Two classic concerns with mountain flying are density altitude and pressure altitude. Actual altitude doesn’t affect aerodynamic performance. Most of us plan our high-elevation arrivals and departures as early in the day as practical, and are extra attentive on warmer days when seated behind a normally aspirated engine. While reduced horsepower is certainly one reason to be wary of high-DA situations, the thinner air also means higher true airspeeds—and lower indicated ones—resulting in the airplane “thinking” it’s higher than it really is. The impact is felt through mushier controls, since there are fewer air molecules flowing over them. There’s also an impact on propeller efficiency, since its blades are airfoils. The net effect, of course, translates into longer, faster takeoff rolls.

I looked up from my checklist to see a 20-foot wall of flame and smoke coming at me very rapidly. The only good thing was I would be taking off into the wind. Five years earlier, this old dirt and grass road near the settlement of Rogersburg, Wash., was used as an airstrip. When ownership changed from private to the BLM, the airstrip closed. It took five years of negotiating with the feds, including Congressional, AOPA and EAA involvement, to get back part-time use. This dirt and grass strip is 1550 feet long at 850 feet msl and parallels the Snake River. Shortly after BLM again allowed access, we got permission to mow it. Two friends used their Super Cub to fly in a brand-new lawn mower and I brought a weed-whacker. I parked my 172 at the end of the strip, in front of the Super Cub.

Cessna is on the verge of delivering its first Corvalis after it took the high-end piston single out of production nearly two years ago. We recently had a chance to fly a developmental copy of what will become the new model, the Corvalis TTx, and to Cessna’s credit, the airplane is not new in name […]

Approach, could you read back the arrival waypoints…we can’t seem to find that arrival….” The request got my attention because it came from the aircraft somewhere ahead of me in the soup of a thick overcast, headed to the same airport. The controller had just warned of a pending change to my arrival plans by changing those of the flight ahead of me. Taking that change as a cue, it was easy to turn to the last plastic-protector page in my little IFR folder—where I’d already inserted the appropriate page. It was less luck than experience, which had tutored me on the likelihood of a traffic conflict with another airport’s arrivals.

One cloudy spring day a few years ago a Beechcraft Baron piloted by a high-time ATP and with a relatively experienced private pilot in the right seat hit a peak in the Ruby Mountains of eastern Nevada while en route from Truckee, California, to Salt Lake City. Both occupants were killed in the crash. The […]

There are efforts under way around the country (and around the world, in fact) to redo Part 23, the iconic regulation that addresses the certification of light airplanes. While we’re still years away from a final rule, these first steps are critical to the ultimate success or failure of creating a new regulatory landscape for […]

If you’re fortunate enough to live a long life, you may reach a point when you start to wonder whether it’s time to retire as pilot in command. You may feel that your vision or mental status isn’t up to par, or you may begin to have trouble entering or exiting the airplane. The point […]

Twice in a lifetime is two times too many; two times when the operator of a moving machine stared a hole right through me and rendered me invisible. In both cases perfect conditions prevailed—nothing obstructed the view, yet our machines converged at a good clip. My first experience came at the hands of the driver of a 1977 Cadillac. My solution was to lay down a vintage motorcycle. It wasn’t my preferred choice, but obstacle and traffic conflicts made lateral maneuvering unwise. The second time came courtesy of two pilots in a Skyhawk during a VFR arrival to a non-towered airport in Florida’s panhandle.

In this article, I will ask readers to suspend disbelief until you have read the article completely. I am sure you will have your own opinions, about both the article and my own motivation in writing it. I believe, however, that most of you will appreciate the message I am trying to convey and that you will also observe how the stakeholders in aviation safety may be approaching the subject in completely different ways. The key questions are not only about how effective they are individually but how they can remain complementary.

Forget about flight reviews and instrument competency checks. Part 135 operations are conducted in a thicket of regulations. Among them are the requirements of Section 299: ** a)** “No certificate holder may use a pilot, nor may any person serve as a pilot in command of a flight, unless, since the beginning of the 12th […]
