Another Look

At one time or another, weve all passed an FAA knowledge test requiring us to calculate aircraft performance for various phases of flight, such as takeoff, cruise and landing. Even though weve been trained and tested on our ability to interpolate the answer down to the foot, mile, minute or gallon, these calculations alone dont ensure were always operating the aircraft prudently. For one thing, they dont account for poor technique, worn equipment or errors.

For almost as long as Ive been flying, the general aviation industry has been in upheaval. By the mid-1980s, product liability concerns and tax law changes helped remove what was propping up things, and the bottom fell out. Among other outcomes, Cessna stopped making piston-powered airplanes altogether while other manufacturers discontinued numerous models, preferring to concentrate on one or two.

At about 0937 Mountain time, the airplane was destroyed when it collided with mountainous terrain. The private pilot and three passengers were fatally injured. Instrument conditions prevailed.Radar data show the airplane reached its cruising altitude of approximately 8000 feet msl some 12 minutes after takeoff. The airplane subsequently descended about 1300 feet in one minute before entering a momentary climb, which was followed by a shallow descent. In the remaining two and a half minutes, the airplane maintained a 300 fpm descent rate, with some intermittent climbs. The final two radar targets show the airplane climbed about 425 feet in 12 seconds. The airplane maintained a straight track from its departure airport to the last radar target, which was within 0.1 nm of the 6670 feet msl accident site.

By now, U.S.-based flight instructors and training organizations should be fully up to speed on last years formal implementation of the airman certification standards (ACS), which is designed to eventually replace all practical test standards (PTS). For now, only the private pilot and airplane instrument rating checkrides employ the ACS, but more are coming. The new standards went into effect June 15, 2016-if youre in the primary training environment and dont know about the ACS, you havent been paying attention.

During a routine inspection, the technician noted the strobe lights would remain on after the switch was selected off. Troubleshooting revealed the switch to be defective. Removing and disassembling the switch revealed the solder joint holding the braided wire had broken and welded itself to the line post. Switch was replaced IAW AD 2008-13-17 in May 2009.

according to the NTSB, and was forced to ditch the airplane in Seattle’s Elliot Bay, out of gas.

One of the more common complaints heard when pilots gather is that someones spouse and kids wont fly with them or dont like flying in little airplanes. The person issuing the lament insists he (its almost invariably he) cant figure out why. Often the reason is he has scared the bejabbers out of his family members at least once and has displayed absolute cluelessness when it comes to making the flight an enjoyable experience.

What if getting to B by burning as little fuel as possible is our objective? Or we want to stay aloft as long as possible? There are speeds to fly to achieve those goals, but well have to slow down, usually a lot. And those exact speeds, for best range and for best endurance, usually arent published for personal airplanes. A workaround is to simply use the lowest book power setting. If no limitations prevent it, best range or endurance usually is found at even lower power.
