Instrument Flight

Perhaps you’ve seen the widely distributed aviation video 178 Seconds to Live. The narrative starts: “The sky is overcast and the visibility poor. That reported five-mile visibility looks more like two and you cannot judge the height of the overcast. . .” It continues: “. . . You find yourself unconsciously easing back just a […]

Proposed San Francisco Class B airspace changes would enable lower-angle descents into SFO optimized for the higher glide ratios of modern jet aircraft, reducing noise and fuel consumption. “A low thrust descent in a clean configuration results in the smallest noise footprint [regardless of altitude], and a descent in a clean configuration at near idle […]

Change is certainly a constant in aviation. Beyond aircraft technological advances, the rules that govern how air traffic control handles those aircraft are also frequently adjusted. One area in particular that’s seen significant discussion and change in the past three years is opposite direction operations (ODO). The official Pilot/Controller Glossary defines ODO: “Aircraft are operating […]

General aviation pilots make IFR takeoffs in reduced visibility and low ceilings on a daily basis. We line up, launch, establish a climb, transition to the gauges and press on with the flight. Assuming there is an approach with adequate minimums at home plate or a nearby airport, we’re confident we can return and land […]

Each month IFR Refresher highlights an accident involving some aspect of IFR flying that an unfortunate pilot failed to respect. All too often, the pilots are professionals who have achieved considerable success in their career fields. The question often asked is; how persons with such a high personal performance standing can allow themselves to be […]

Every year structural icing claims a small but steady number of airplanes. Many of the accidents are on approach in clear air—after the airplane has already collected a load of ice. We look at them afterward and wonder—the airplane had been doing fine—why did it crash well after it escaped from icing conditions? Full-scale airframe […]

I was doing one of my periodic office de-clutters this week and up on the far northwest corner of one shelf, I found some interesting artifacts. Like an archeologist dusting off pottery shards, there was the last of my Jeppesen binders and a stack of paper charts, some dating to 1997. I can’t remember when […]

I’ve never felt it was appropriate that a pilot could obtain an instrument rating without flying in the clouds. From a safety standpoint—no matter what type of flying the pilot intends to undertake—it seems beyond ludicrous. I received instrument dual in IMC at a small airport in rural Iowa; one would think that it would […]

Aeronautical decision-making (ADM) is essentially the mental process of gathering and evaluating information pertinent to a flight; listing the options and their attendant risks; and then choosing the best alternatives. It is an iterative process due to the nature of the changing variables inherent in flight. ADM is often a relatively simple and subliminal process […]

Good judgment and quick thinking are hallmarks of the aviation mentality. Both pilots and air traffic controllers are in the decision-making business. For controllers, every moment our headsets are plugged in, we’re making choices that affect the safety and flow of traffic in our airspace. Some choices are easier than others, such as not clearing […]
