Circle, But How?

Last night I took off from runway 9 when an airplane was turning base for runway 27, forcing a go-around to save the situation. How could I have made such an egregious error? Quite easily, Im afraid.

Now I can readily appreciate how some of those mid-air collisions at non-towered airports (or airports after the tower closes).

I am a 200-hour pilot and was out getting some night experience at an unfamiliar airport. The AWOS reported the winds were calm, so I had my choice of runway 9 or 27. The airports calm wind runway was runway 9 and an airplane had just taken off on 9, so I thought I would stay with the flow.

I taxied to the end of the runway and was conducting my runup when a…

OSH Till You Drop

Having just survived another AirVenture at Oshkosh, its fairly clear that pilots are both the smartest and the dumbest people on Earth.

Lets step aside for a moment and try to ignore the pageantry, the forums, the camaraderie and the sheer amazement that comes with watching Sean Tucker fly an airplane. Instead, consider the Stuff for Sale.

There are few other places on the planet where you could spend so much money and still not get one of everything. Headsets, charts, navaids, engine monitors, weather info, parachutes, hangars, traffic alerts, FADEC, airplanes, engines, seats. That just scratches the surface of the wares hawked at the worlds biggest airshow.

Pilots are experts a…

Hot Stuff

The following information is derived from the FAAs Service Difficulty Reports and Aviation Maintenance Alerts.

———-

An FAA certified repair station received a Janitrol cabin heater combustion head in exchange for a new part purchased by a customer. The trade-in combustion head had a hole approximately 0.4375 inches in diameter burned through it and the entire part was severely corroded.

Clearly cabin heaters are operated with minimal maintenance until they fail. A pressure decay test of this unit would have made its deficiencies obvious.

Cabin heaters are neglected during the summer, then expected to perform perfectly during the first cold snap. However, cabin heaters tha…

Future Foible

I thought Future Flight [Reality Check, July] contained great visions, however, I didnt read anything in the article about spatial disorientation. All the fancy new tools for navigation, weather and etc. still leave the vertigo problem unsolved.

A new advanced instrument panel should have some means of addressing the problem. Maybe an attitude display that has real depth to it, instead of perceived depth.

-Lester Zinser

The advanced displays typically include large display screens with an artificial ground profile derived from the GPS database. Research shows the design works much better than traditional attitude indicators at enabling the pilot to …

Preliminary Reports

The following briefs were selected from the 223 preliminary reports filed with the NTSB in August 2001. Statements in quotes were taken directly from the NTSB documents. The information is subject to change as the investigations are completed.


Aug. 01, Sugar Grove, Ill.
Beech Bonanza

At 11:31 central time, a Beech A36 lost engine power and was damaged in the ensuing forced landing. The pilot was not injured. The flight was a post-maintenance test flight and the airplane had just come from its annual inspection. A ground run showed no anomalies, but during a post-accident inspection it appeared a fuel line had loosened enough to leak but not enough to come off its f…

Sticking to Cement

[IMGCAP(1)]The key for all landings is the pilots ability to estimate how the airplane will descend to its landing. This ability directly affects the timing of configuration and power changes and the amount of maneuvering that might be necessary to arrive at a suitable touchdown point. The pilot needs to be able to maintain the correct glide angle while maneuvering the airplane.

The most important ability – and it comes easier for pilots with glider flight experience – is the ability to estimate the gliding angle and what distance can be picked up with it. All pilots should be able to do a pretty good job of estimating where their airplane is going to land, knowing the normal glide ang…

Snowhere to Hide

[IMGCAP(1)]Ill admit right up front that I live for winter. After dealing with the sweltering heat and high density altitudes of the summer, its a relief to have the cooler temperatures.

However, there are the obvious dangers with operating in a snowy climate, to include frost and snow covered aircraft surfaces, snow covered runways, rapidly changing weather, lower visibilities, more hours of darkness and icing, just to name a few.

In snow country, the preparation for a winter flight is more time-consuming than a summer flight because of these conditions, and requires some additional items and procedures.

When planning a winter GA flight, watch The Weather Channel. You can get…

Nailing the Needles

[IMGCAP(1)]The first time a pilot on an ILS approach sneaks under the glide-slope is almost always a situation where he is on an ILS final, approaching minimums. Hes close to decision height and suddenly there are patches of ground appearing intermittently below. An instant later, the strobes are visible. He drops below the glide path and the runway is straight ahead. The pilot later realizes that remaining on glide slope at decision height would have meant executing a missed approach and possibly a trip to the alternate airport.

On the next gamble, he descends a little bit more below the glideslope path – and it works again. In fact it may work a number of times. The best estimates i…

Risky When Real

[IMGCAP(1)]I was driving down a country road when I had to blink to make certain I wasnt hallucinating. There was a Cessna 152 by the side of the road. It was undamaged, which was surprising because the road had a number of power lines running along it.

I stopped to see if the person standing next to the aircraft was okay. He said the flight instructor had pulled the mixture to simulate an engine failure when they were doing S turns along a road. The student had few options for an emergency landing area and chose the road. There was no time to try re-starting the engine.

The student said the flight instructor had walked down the road to try to find a better stretch of the road for…

Going Up, Going Down

Theres a classic childrens story in which a little train says I think I can, I think I can – and lo and behold, it can. The power of mind over body is ably summed up in the tale, as it is in cliches such as when theres a will, theres a way.

But whos fooling whom?

Sure, there are times when you can suck it up and get through whatever it is you have to get through. Who hasnt had to work through a deadline or clear a fallen tree before dawn or pull an all-nighter through college? Sometimes you just have to do it.

But for every time you manage to endure the agony, there are countless times when you punt. With your exhaustion swaddling you like a Los Angeles smog, you wearily…
