    The Greatest Threat to Aviation Safety

    According to the people who ought to know—the NTSB, Flight Safety Foundation, Boeing—recent studies indicate that the biggest threat to aviation safety is pilots not doing go-arounds.

    Excuse me?

    Apparently,pilots need to recognize and respond faster to unstabilized approaches (approaches that need correction in heading, speed and/or altitude.)

    Pilots tend to want to land when they come in for a landing; and surveys indicate that although airline requirements are to abort landings if their approaches are unstable, go-arounds happen proportionally less often than they should. The Director of Global Programs at Flight Safety Foundation, Rudy Quevedo, “The physics of landing mean that the plane should be centered, on the correct trajectory, the correct descent rate and the right speed.”

    In George’s Point of View

    This conclusion seems to me a major oversimplification of the multitude of aviation problems.

    I would not presume to say that I know if weather, mechanical failures or human failures are most frequently responsible for aviation disasters. I do know that problems tend to occur together.

    I know, for example, that there are countries (like India where a recent aviation school scandal revealed the licensing of pilots who cannot fly or pass flying exams.) When a pilot who couldn’t pass his flying exam has an accident, a go round would not have helped.

    And as for a crash like the Boeing 777 operated by Asiana Airlines that crash landed at San Francisco International Airport–the plane flown by someone unfamiliar with the airport and the plane he was flying came in too low and hit the seawall (among other things.) How can one say that failing to make a go around was the problem–when the plane was too low and at the wrong angle even before reaching the runway.

    It is easy for a statistician to say some of these accidents could have been prevented with a go-around; but in how many of these accidents was a go around actually an option? Planes hit seawalls, encounter wake turbulence, strike cables, have flat tires, flap failures, bird strikes, suffer wind shear, idiots who attempt to open doors in mid-flight, and hundreds of other problems. A go-around is not always an option.

    Undoubtably, especially on small planes, a second or even third shot at landing will correct minor landing physics issues. It’s probably somewhat easier on a small plane than a 777, And if you ask a pilot that had a runway overrun, he will probably tell you the exact instant when he should have gone for the go-around, and knew when it was too late.

    It should be noted that sometimes when the plane is on a wrong trajectory, incorrect descent rate, and wrong speed, it might not be possible to manage a go-around; there may well be a factor like a bird strike, mechanical failure, faulty flight indication, or icing crimping the physics.

    It’s very easy for a guy with a pencil in his hand to say pilots should have aborted their landings at the first sign of trouble. Sometimes we should look at surveys and statistics like Mark Twain, and realize that “There are lies, damned likes and statistics.”

    Rudder Failure Fails to Alert Crew

    What: Air Canada Airbus A319-100 en route from Montreal,QC to Toronto,ON
    Where: Montreal
    When: Apr 14th 2009
    Who: 117 on board
    Why: As the plane was about to lift off, the rudder moved and the aircraft pivoted to the left. The crew completed the flight. Afterwards, maintenance in Toronto was informed and they replaced the yaw damper actuator and the #1 flight augmentation computer.

    George’s Point of View

    I question whether the crew should have continued on with this flight on board this plane before the maintenance repairs were completed. It is obvious that everyone survived and that is a good thing. But I wonder if the convenience of not stopping is worth either 1. the actual risk; 2. the perceived risk 3. passenger confidence.

    As far as confidence in an airline goes, as for me, ask me any day and I’ll tell you, I’d prefer to be a little late to being a little dead. I think most passengers would agree.

    If not stopping to perform repairs is Air Canada’s policy, then someone needs to rethink this policy, because the issue is not consumer confidence vs the bottom line. It is safety vs foolhardy cutting of corners.

    Business Jet India and SpanAir’s Planes Grounded for Violating Safety Norms

    The Directorate General of Civil Aviation (DGCA), India, grounded two business jets belonging to Business Jet India Private Limited and Span Air for violating safety norms during its safety audit of non-scheduled operators (NSOPs).

    During the inspection of the Cessna aircraft belonging to Business Jets India, the aviation regulator found that the crew on-board were not properly trained in safety and emergency procedures. The log books and the operation manuals were outdated and the lavatory had unnecessary goods which is strictly prohibited. The Business Jets India Private Limited operates three Hawker 850 XP aircrafts in addition to the Cessna Citation CJ2 aircraft in and out of India. The company is a subsidiary of Singapore-based BJETS Private Limited. Tata group also has a stake in it.

    Moreover, the aviation regulator also found some significant deficiencies in the Hawker 900XP aircraft registered VT-BKL with SpanAir. It was observed that the crew were not properly trained in safety and emergency procedures, the life vest had passed its expiry date and the operations manual and the route guides were outdated. SpanAir has four more aircrafts –a seven-seater Beech Super King Air B-200; a six-seater Premier 1A, Bell 407GX and Bell 420 helicopters.

    Virtual Airport


    At smaller airports, the controllers direct traffic and manage the airfield. Currently, pilots using the Beckley-area airport talk among themselves to advise themselves of traffic.

    An actual, physical tower would cost between $2 million and $3 million, with an ongoing annual expense of $450,000 for maintenance. A virtual tower would be far less expensive.

    Quadrex Aviation LLC, based in Melbourne, Fla. is developing a plan for a computer-driven control tower for Raleigh County Airport Authority. The report will be out in September. “If this does work as advertised, or even better than we imagined, then that holds the promise out to a lot of airports that could never afford to justify a control tower in the first place, and to provide that level of safety in an environment where you’ve got a lot of people trying to occupy the same air space.” according to Dr. David Byers, senior development professional for Quadrex Aviation LLC. And, regarding the Beckley area airport, “It’s kind of like an airport graduating from a two-way stop at an intersection to a four-way stop, and you reach a certain point say, at a four-way stop, and if you’ve ever been in that situation, well, who’s next? You may decide, ‘Well, you’re next,’ and somebody has the same opinion and attitude, and the next thing you know, there’s a conflict there. The concept at Beckley is to explore the opportunity of actually setting up a facility where they can test the technologies, to see ‘here’s what we think it’s going to do,’ and to put it in a facility where it can be managed and monitored to see if it’s doing what it’s advertised to do and get some feedback from the pilots and essentially be a prototype of other systems that could go up around the country.”

    FAA Innovations

    The job of a controller is to keep planes at a safe distance from each other. The FAA has a new electronic air traffic control monitoring system that tracks controller error.

    The new system has revealed serious errors made by controllers have been underestimated. The new system is augmented by electronic surveillance and controller self-reportage.

    Controllers made 41 high risk errors out of a total 4,394 errors last year. That is two times the errors in 2010 and three times those in 2009.

    We should consider that of 132 million flights handled, 41 serious errors is a small percentage of error. Of course, it is only a good thing that the FAA is working on reducing errors.

  • Is the Q400 Safe?

    When looking at track records, the biggest question of safety in the Bombardier Q400 seems to be the failure of the landing gear to retract. Airworthiness directives in the archives refer to this issue as “fatigue failure of the nose landing gear electrical harness” although when gear retraction failed in 2007 on a Scandinavian Airlines plane, the cause of the failure was described as “hydraulics actuator top eyebolt was separated from the actuator.”

    Of course in the Buffalo Crash, the landing gear issue did not come into play.

    Significant icing may have been THE problem. It may have been icing that crippled the plane, period. It may have been a salvageable situation. It may have been a crisis situation that nine out of ten pilots could have handled–or 1 in 100.

    Or it may have been one of several factors.

    The Buffalo flight apparently slowed enough to lose lift.

    When the stall-warning system angled the plane’s nose down to regain speed, instead of following the proper procedure–lowering the nose to get out of a stall–the captain pulled back on the controls and added power.

    Pilot training is being discussed as a factor in the crash. Or was it as James Fallows postulates a “tailplane stall?”

    However speculation is simply a logical exercise. The NTSB investigation is ongoing as the FBI, NTSB, and FAA examine the flight data and the world waits for an answer.
