Changes Follow Fatal Helicopter AccidentBoth the FAA and NTSB called for change after five people died in a helicopter accident in New York in March. They were flying in a Eurocopter AS350 with the doors off, a popular option for sightseeing flights, and were wearing special harnesses that were difficult to release. The helicopter lost power, and the pilot made an emergency landing on the East River. The aircraft then rolled over and sank. Only the pilot, who was wearing a different kind of harness, was able to escape. The FAA prohibited doors-off flights unless passengers have quick-release harnesses. The NTSB called on the FAA to prohibit commercial flights of all kinds that secure passengers without quick-release mechanisms.

I was able to pull the ODP data but not the SID data, but I can give a fairly good guess as to whats going on. On the ODP, the controlling obstacle is a 2729-foot tower a few miles to the east of the runway. The initial climb is extended a bit more than usual in order to allow for a standard climb gradient when turning right (note that for turns other than to the right, a normal 400-foot turn is allowed). The WENDY and TRUPR are examples of Open SIDs, which have a route off the runway followed by radar vectors to a route. In these cases, the route off the runway is evaluated, but then the radar vector area gets no additional evaluation (other than MVA, etc.). SID evaluation begins again at the defined route. Because theres no SID evaluation required after the initial climb, the controlling obstacle for the ODP isnt considered. The minimum turning altitude for an RNAV SID is 500 feet above the runway, which would give you a turn at 1800 vs. the turn at 1900 on the ODP to keep a standard climb gradient and clear the tower. -LS

Before the advent of GPS approaches, most civilian approach control facilities provided Airport Surveillance Radar (ASR) approaches, usually as a back-up to pilot-nav approaches. Many are now gone but some airports still have them. In Florida, only two civilian airports have ASR approaches: Key West and Tallahassee, at opposite ends of the state. However, there are seven military airports with ASR approaches.

Its the end of a long day filled of uncooperative weather, ground stops, and a diversion tossed in to make it interesting. Youre shooting the non-precision (of course) GPS approach, and upon reaching minimums, you look up and see … nothing. Wait a minute! Isnt that a PAPI glowing out of the left side of your window? Is that your runway? If so, whats it doing all the way over there?

For some, the shoulder seasons mean ideal flying weather – crisp spring and fall mornings with great visibility, often under a stable ceiling. These conditions offer fantastic climb performance, and the lack of bugs splattered all over the windshield is a plus. Morning fog, too, is pretty to look at, although it sure puts a damper on early-bird departures.

From time to time we look at weather accidents, reviewing the factors that might have led to poor decision making or perhaps even weather that could not be anticipated. In this edition well take a look at the crash of a Pitts biplane in IMC conditions in California, and a Beechcraft Baron that went down in bad weather in Kentucky. Both of these incidents took place in April, so they should give you some food for thought this time of year.

On the way out of Florida for Hurricane Irma, it was very, very busy on frequency with everyone trying to get out of the state. ATC was doing a great job of handling very heavy traffic loads, and still managing to provide flight following to the greatest extent possible, when I happened to overhear the following exchange:

For the 14th year, the U.S. Sport Aviation Expo welcomed visitors to Sebring, Florida, in January, providing respite from the cold for northerners and a chance for prospective buyers to take a demo flight in a Light Sport Aircraft. The show hosted about 100 exhibitors, more than last year, and organizers told AVweb ticket sales also were up. About 60 forums were held, and more than 1,000 youngsters took part in the shows youth education programs. The date for next years event is January 23 to 26.

In 1984 when I got my instrument ticket, I was taught to use FROM when identifying crossing radials. I dont know if that is a standard practice or simply my instructors way of doing it. In Octobers Killer Quiz, Gone to the Dogs, you are identifying PLAZA via TO the 173-degree radial. My way would have been to dial in 353 and use a FROM indication.

When asking air traffic controllers about their jobs, you might occasionally get the answer, Best job in the world. Its a demanding, technical career thats both very rewarding and-while not glamorous-carries a certain mystique with the general public.
