Comair Layoffs

Comair Expects Furloughs of up to 100 Pilots Starting in September in Wake of Service Cuts (AP, July 9)

Comair expects to furlough up to 100 additional pilots between September and the end of the year in the wake Delta’s decision to make service cuts.
The airline placed 295 pilots on furlough in October.
A Comair spokeswoman said Thursday that the regional airline is working with ALPA to explore ways to lessen the impact. She says the number of furloughs could be reduced through voluntary options.
The pilots union says the company has indicated those options could include unpaid leaves, early buyouts or reduced work schedules.

Comair employs about 1,380 pilots.

Safety is Local

Why is being local an important aspect of any safety program?

The answer is quite simple: the owner of an asset has the most vested interest in preserving the assets by a safety program. Government and other organizations do have safety programs and they are important to aviation, especially commercial aviation. But the local program has the ability to address every threat to the preservation of assets, even those which might not initially alarm or get the attention of a government program.
Here is an example: Several years ago, the FAA and the City of Sacramento opened a previously closed former military airfield as an additional city airport. The airport was not crowded, but late night noise was an issue for the main airport neighbors. So air express cargo and package airlines were moved to the new field.

But neither the FAA nor the companies were alarmed by the airfield being put into operation without an air traffic control towner, without a crash fire and rescue crew and equipment, and without approach lighting and radar.

The pilot association was alarmed and raised the safety concern locally at the company, the city and the FAA. It was the local concern expressed by the pilot group which led the FAA, the city and the company to install a working tower, crash crew, approach lighting and radar.

Local input in safety programs is critical to safety. The upshot is that the company has suffered no aviation mishaps, in what initially was a high risk operation.

Air France 447, Airbus 330, Rio to Paris 1 June

The Weather Channel displayed an inter-tropical convergence zone (ITCZ) satellite shot of the area at the time of AF447 passage through the area. The Sat shot showed large areas of high cloud tops. This suggests ongoing convective activity. Routine meteorological knowledge of the troposphere in the tropics places the trop layer at about FL600.

In laymen terms, the thunder-boomers were likely topping out at 60,000 feet. The coverage for the area looked as if a flight would have to pick its way though and might not be able to “stay on the track of the course.”

If this metro estimation is relatively correct, the violent convection turbulence, hail, lightning and precipitation would make the transit of any cell or area of cells on this track or this course to be extremely hazardous.

Additionally, one other hazardous character of convection in the tropics is very rapid cell growth. Cells can grow at rates in excess of 6000 feet per minute. This means that a cell could literally grow right up in front of you in what may have appeared on radar to be a clear area. Pilots who fly to South America from various Miami airline domiciles can verify this amazing metro phenomenon when in the tropical inter convergence zone.

Three other safety things are troubling to me though: If the Weather Channel can have this data available for presentation to me, while I am sitting in my den in my house on my TV, why doesn’t airline’s flight control dispatch have this current data available for presentation to the flightcrew in the cockpit real time, while in flight? Remember that the preflight briefing occurred about 5 hours prior to the thunderstorm area transit, the transit was at night and this ITCZ is extremely dynamic both vertically and horizontally.

Why are Convective Sigments merely passed to flight crew, without flight control route hazard analysis, on the presumption that only the flight crew in flight, are to plot each weather report and compare it to the flight path to determine the hazard? Is not the company a stake holder in this issue? Should not flight control determine if the activity is in the flight’s path and recommend the safest path around the severe convection?

Why isn’t this done on the ground where more resources are available?

Next, does Air France have a procedure whereby flight crew are required to avoid convective cells by 20-30 miles? Do Air France flight crews actually comply with such a procedure? Is it a procedure or is it a policy? At your airline, is this avoidance a policy or a procedure?

Can an airborne radar with perhaps a good 80 mile range be expected to be sufficient equipment to circumnavigate an area 200 to 300 miles in width? Once in clouds, how capable is an airborne radar, in comparison to ground based hourly sat photos and infra red cloud top imaging?

Lastly, I suspect that there were other flights in the area at the time, heading to Europe and other points. What did they see in terms of weather? What did the official weather agencies report? Did any coordination transpire to assist the flight crews? Was there any chance of weather radar from Brazil being transmitted to flights in the area?

Let’s see, Antoine De Saint Exupery wrote about this in his 1931 novel “Night Flight.” ISBN 9780156656054

[Opps, I forgot, The Patagonian Weather services set up in the mid 1920’s, may not have changed much. I wonder if the same guy may still be working there with a sandwich, thermos of coffee, pack of cigarettes and a sharp pencil.]

How many times have pilots heard some version of this statement? “It is not our job to advise pilots about what they are supposed to do. It is our job only to observe and report the weather, the cloud covering and rain.”

Expensive Investigation? Better Operating Alternatives?

What are the costs now being incurred by Brazil, France, Air France, Airbus and all other parties to the AF447 disaster? Ever thought of that? My estimation is that more than $500 million will be spent in the next 2-3 years in operations related to this mishap.

I wonder what would be the costs for Air France and other airlines of keeping the requested and cleared flight paths for scheduled flights clear of areas of massive convective thunderstorms, by using real time satellite photos, dispatch reroutes and various satellite and HF communications? By the way all of the technology is on board the airplane and in flight control dispatch offices.

Safety Riddle

Safety Riddle: Does the mishap cause the hazard to occur or does the hazard cause the mishap to occur?
According to the FAA, Congress and airline transport associations safety experts, every thing is fine, until every thing is not fine. Read this case below:

Crash Puts Focus on Air Safety-Senate Panel Plans Further Hearings (Washington Post, May 15)

A U.S. Senate committee is planning to hold a series of hearings next month looking into the safety practices of commercial airlines, following revelations of a number of safety lapses from the crash of Continental Connection Flight 3407.

The announcement came on the final day of public hearings by the NTSB into the Feb. 12 crash near, which killed 50 people. The crash was the first fatal commercial aviation accident in two years and has been described by the NTSB as the worst transportation accident in seven years.

In an interview yesterday, Sen. Byron L. Dorgan (D-N.D.), chairman of the Senate subcommittee that oversees aviation, said he was “stunned by what I’ve seen and heard on the evidence” from the safety board hearings.

“There are issues of training, crew rest, exam failures, acquaintance with icing,” Dorgan said.

“There are so many things that are troublesome. It calls for a real serious investigation.”

Dorgan said he met yesterday with families of victims of Flight 3407. He said his committee’s hearings will examine the safety practices of the regional airline industry, which has grown as major airlines contract out service to smaller cities. Colgan Air, which is the Manassas-based unit of Pinnacle Airlines, was operating the Buffalo flight as a regional partner of Continental Airlines. The hearing will also focus on the development of safety standards for the airlines by the Federal Aviation Administration. “We’ve had a remarkably good record [in aviation safety],” Dorgan said. “But it’s my understanding that those commercial airline crashes in recent years have overwhelmingly been commuter carriers.

My question is this. Didn’t the safety hazard issues exist before the crash occurred? Why is Congress, FAA and other safety experts looking at these issues after the crash occurred? Why didn’t they look at them before the crash occurred?
Do they believe that the crash caused the hazards to occur? Is that why they are looking at them now? But in contrast, wouldn’t the average person believe that the hazards were there all along, waiting for a challenging situation to bring them out? Any pilot can fly on a fair day. But does it not take a well trained pilot to fly on a dark and stormy night?

Would you agree that the hazard occurred before the mishap and in fact was directly related to the cause of the mishap?

So what is Congress doing? Here is the answer. Congress are lawyers. In tort law, you have to have an offense before you can go to court. You have hearings also before you go to court, to determine if a court proceeding is justified. So these hearing and the Congressional action is related to finding blame for the damage done. That is why the hearings are taking place after the mishap occurred, That is what lawyers do. They take injured parties to court and try to get recompense from the parties that injured them. That is what is going on here.

This is not safety.It is too late to practice safety when the mishap has already occurred. This is just tort law proceedings under the guise of Congressional hearings. The goal may be legislation, but to do what: To make the FAA live up to their own policy of “ONE LEVEL OF SAFETY”?


Well Paul, a worthy initiative for sure. At least you got me curious, particularly about how we aregoing to get to a useful forecast. And also about how we will get investments in effort (andperhaps even money) going in anticipation of future threats. (This is a bit of an achilles-heel for initiatives such as FAST as well). This would seem to me to be some of the challenges here. And as challenges make life interesting, this is not a bad thing. Do you have some ideas already ?

Safety Forecasting???

Every field prepares and presents regular forecasts. The most common example of course is the daily weather forecast. We can make an activity plan for our day based on the weather forecast. But other f0recasts are equally important to us. Who doesn’t listen to the sports forecast for the baseball or football season? Who doesn’t listen to the financial forecasts, especially in these times? Production forecasts, crop forecasts, marketing forecasts, political forecasts-well the list goes on and on.

We all listen to forecasts to determine a plan of action.

But how about safety? How does we make a plan of action for safety activities? Do we make a plan of action? Or do we just re-act to circumstances? Are we the “tail being wagged by the dog” in most cases, when it comes to safety?

This blog is dedicated to safety professionals, managers who have to make a plan to keep their organizations running smoothly without losses due to injury and material damage.

I hope that we can share our ideas and make our organizations safer each day through forecasting and planning. Welcome aboard!!
