What NASA Won't Tell You About Air Safety

rabble writes "According to a report out of Washington, NASA wants to avoid telling you about how unsafe you are when you fly. According to the article, when an $8.5M safety study of about 24,000 pilots indicated an alarming number of near collisions and runway incidents, NASA refused to release the results. The article quotes one congressman as saying 'There is a faint odor about it all.' A friend of mine who is a general aviation pilot responded to the article by saying 'It's scary but no surprise to those of us who fly.'"

    I fly a reasonable amount as a passenger (used to fly small private aircraft as well) on commercial airlines and I've seen quite a few planes that come by shockingly close. I was prepared early enough one day to get a reasonable pic out of a cheap little point and shoot here of another aircraft in reasonably close proximity, but this is by no means the closest I've seen planes fly to one another. One time flying over Columbia on this flight we followed *very* close to another large commercial airliner for quite some time. It was hard to get a picture given it was at night with a little point and shoot, but it was close enough for me to see people in windows in-between flashes of lightning. Granted this was in controlled conditions as we were flying almost in formation, but I've also seen planes flash by in close proximity flying in the opposite direction as well. Much closer than the 3-5 mile limit I understood was in place.

    Given the increasing amount of air traffic, I would not be surprised to see incidents (not comforting given upcoming travel), but the shocking thing is that the FAA (and the public) is still dealing with a completely antiquated air traffic control system that like other aspects of our national infrastructure is woefully lacking, particularly around large airports.

      There is really no need for this alarmism.

      I am a general aviation pilot with about 800 hours and nothing you saw is the slightest bit out of the ordinary. The "3-5 miles" is the lateral separation for two aircraft in cruise flight at the same altitude. As long as you're separated vertically by at least 1,000' (which the first aircraft pic clearly was - probably 3000' above you, in fact), there is no lateral separation requirement at all. Many times, I'll fly directly under or over a commercial jet, which is fine since the controller knows we're at different altitudes.

      Your second picture pretty clearly shows you on approach to an airport - SLC. Salt Lake City has parallel runways (see http://www.airnav.com/airport/SLC) and under certain conditions, to improve airport capacity, simultaneous parallel approaches are allowed. That is, two aircraft simultaneously landing on parallel runways. This is perfectly safe because the aircraft aren't just randomly cruising around; they're being held to extremely tight lateral guidance by the runways' Instrument Landing Systems (ILS) so they don't conflict.

      And, finally, at any time, during any phase of flight -- as long as you're not in a cloud -- a controller can always have the following conversation with a pilot:

      ATC: You have traffic, 11 o'clock, 4 miles, 8,000 feet, moving northbound. Report him in sight.
      Pilot: Traffic in sight.
      ATC: Roger, maintain visual separation with that traffic.

      Now the two airplanes can get closer than the 5 mile limit; the pilot has reported the other airplane is in sight and is doing "see and avoid" -- basically, the same way you avoid hitting other cars when you're driving.

      I hope this has been informative enough for you to, please, stop posting alarmist blog entries saying "Oh my god, look at that plane, it's way too close!" Really, these are all quite normal operations.

      If the purpose of the program (increasing air safety) will be maximized by not releasing this report to the public then NASA is right to not release it. Pilots are very sensitive about their jobs, especially when safety is on the line. If pilots are more likely to report incidents (near-misses and dangerous situations) if they know that the data will only be used internally then not releasing it is the right answer.

      I know that pilots were given anonymity, but there are plenty of incidents that could be recognized by the description (it's not hard to figure out which airlines fly a lot of routes -- Southwest and JetBlue, for example, are the only carriers between a lot of secondary airports).

      If the report is published to the greater world then pilots might not be as forthcoming about future incidents and we might lose a good chance to prevent an accident. Without knowing more about the report, why it was developed, who developed it, and what good it does I can't say for sure whether that's the right answer or not, but it's at least a reasonable answer. There's no conspiracy here, sorry.

Would you call yourself an idiot if a piece of debris you couldn't see caused one and sent you into a crash? Didn't think so. Doesn't change the good chance of death you have as a result.

      Oh, and are you always the driver when you're in a car? Never let anyone else drive? Never taken a taxi, or a shuttle bus of some sort?

      The numbers are very simple. Compare the number of plane trips per year and number of plane deaths with the number of car trips per year and the number of car deaths. The plane related incidents are almost statistically unnoticeable in this country. Car crashes, on the other hand, are one of the leading causes of death.

      If you are referring to ASRS, then no, the reports are not anonymous. In fact, it is better than that. Pilots are encouraged to report problems, even ones involving the violation of the rules, using their identities, because the report, under normal circumstances, is a "get out of jail free" card.

      The report will not protect you from deliberate violations of the rules, but if you accidentally or due to the safety issue involved had to break a rule, it will limit FAA's ability to punish you. As I recall, if there is an accident involved (defined by FAA terms), it's also not usable. You can use this protection once in five years, I think, but I'm not certain of the dates. (I've filed reports but never needed the protection.)

      The identifying data is removed from the report before it goes into the database. The pilot gets a reciept with a number and date so he can invoke the protections.

Look at the facts: The American airline industry completes thousands of flights every day without a single issue. That is friggen AMAZING! The ATC has a very hard job, and they do it well. A big part of why things are so safe is the over-zealous approach pilots (most pilots) take to safety. There are several different ways to report problems. If you are at a major airport and break the rules (in a small plane for example) you can usually expect an FAA inspector to meet you at the tarmac to pull your ticket on the spot. If you don't take safety seriously word gets around fast. Your fellow pilots don't appreciate it.

    This program has been going for years and years. It helps make the skies above you safer. If there is an increase it is likely due to one of the major trends affecting aviation today. Fewer airports, more airplanes with smaller passenger sizes, more flights, younger pilots, etc. I highly doubt NASA is trying to deep-six some scary fact, they probably just didn't want to pay to deal with the fallout from a service that costs them dollars. They do it for free in the interest of safety. They should be applauded for their years of service to the aviation industry.

    The airliner in that picture on your blog is not violating any recommended practices. The 3-5 miles is typical following distance for airliners on the same path, which allows time for potentially dangerous wake turbulence to dissipate.

But it is also true that most people spend a lot more time in cars than in airplanes.

The per-hour death rate of driving versus flying, however, is about equal.
