FAA Software Aims to Make Flights Easier 130
coondoggie writes "The Federal Aviation Administration (FAA) this week expanded a program that it says will reduce flight delays during the peak summer season. The Airspace Flow Program gives airlines the option of either accepting delays for flights scheduled to fly through storms or flying longer routes to maneuver around them. The agency said that it rolled out a new software program that ensures airports impacted by bad weather receive the maximum number of flights that can safely fly to them."

The outbound flights (at the airport with bad weather),
will be the ones that are delayed, instead of other
flights whose destination is the airport with the bad
weather being delayed.
Ever sit on the plane at the gate for hours
because of bad weather at your destination?
Hot, no drinks, no food, no information, and
you can't go back inside the terminal.
With this plan, it will be the other way around,
because it will mess up less airports.

Collecting stats on just the northeast region
which is high traffic and high congestion does
not extrapolate to the entire system.
Furthermore, measuring the delays during the
summer season proves nothing. The worst delays
occur during the winter, when there is almost
always a storm system (or two) somewhere over
the country.
During the winter, it's a 90% probability
that a large airport is being impacted by wx.

Please turn in your geek card on the way out.
Anybody that has passed intro stats at any level knows (or should know) that effect size and statistical significance are two completely separate measures. You can have a 2% improvement that is highly significant or you could have a 20% improvement that isn't - without the actual data you cannot know.
Now, the question you are trying to ask is if, in medical terms, a 9% improvement is clinically meaningful. If I can show a new drug lowers blood pressure by 2mm hg every single time, the improvement will be statistically significant, but not in any way useful. Just yesterday I was running a hierarchical regression where the final predictor only improved the fit of the model by 3.3%, but the change in fit was certainly significant (p=.004)
If you want to use the word significant as a synonym for meaningful that's ok I guess (I wouldn't). But please don't add the word "statistically" to the phrase in an attempt to make yourself sound smarter. It just makes communicating statistics to the public that much harder for those of us that actually do it for a living.

Is flying through storms all that good of an idea? Really?
"Flying through storms" isn't an accurate description - it's what happens when the mainstream press reports on a technical issue.
Nobody flies through thunderstorms. At least knowingly and on purpose. You fly between them (or over them if you're not stuck in a A320.)
Delays happen in the summer because the traffic trying to pass an area or line of thunderstorms enroute has to squeeze into the areas between cells. Controllers have to maintain a specified spacing between aircraft, so when you have less space for traffic, you have to accept less traffic.
In the past, the FAA would hold aircraft on the ground to keep traffic at a rate the affected area could handle. As I read the summary, it looks like they're going to give airlines the option sitting it out on the ground (rate limiting) or of rerouting well outside of the affected area - effectively a choice between a departure delay or a longer route with ahe increased fuel burn.
Choice is good.

In fact, most pilots who have flown both will tell you the A320 is a much smoother ride in rough weather because the fly-by-wire responds so much faster to any unwanted movement than a non-FBW plane that just bounces around and with the auto pilot responding only to longer term deviations. (ie: the auto-pilot is happy as long as the course and altitude are OK, short pitch and roll changes aren't important) Having been a passenger way too many times on both, I have noticed the same.
