thoughts of an airline pilot

this is a very interesting forum.
i started flying when i was 15. i went to an aviation college for my degree and have been flying commercially for 11 years. i have about 8000 hours of flight time. i also have my CFI / CFII / MEI.
i currently fly for a major airline.
my first question: because of my profession, i see "trails" on a daily basis. how do i tell the difference between benign contrails and malignant chemtrails? |

May I be the first to welcome you.
I have so many questions, I'll start out with a few.
When flying, say at 30,000 ft., do your instruments give you enough information to enable you to know, with a degree of certainty, that you are creating a contrail?
It seems there is so much concern about persistent contrails having a bad effect on the atmosphere, that they could be eliminated by adjusting the altitude a little.
Which brings me to my next question.
When you are creating a contrail, what is the normal/average amount of altitude adjustment it would take to eliminate the trail? That's probably hard to answer, but is there a ballpark number?
Severe problems take severe remedies.
I'll stop with one more.
What happened 6 years ago that changed our skies so dramatically? Contrails were extremely rare and normally did not persist. Period.
Friday, here in the Pac. N.W., we were slammed with pcts, turning the sky white. Today, with identical conditions, at least on the ground, there were none. The sky remained blue all day. Why?
You seem sincere, can you appreciate my concerns? |

Can't wait to hear answers to those questions.
When an area is getting bombarded AA767, there are planes flying by in many different directions. They leave varying types of trails. Some grow into very wide ones. Some have, on one side of the trail, just the stream while on the other side are many curling off shoots. (hard to explain)
These planes go back and forth, many, now, have 2 planes flying together. One behind the other. One bigger then the other. One will be spraying one type of trail while the other has a different type.
Many of these planes are NOT at a high altitude. One day, coming home from work, this plane could not be more then 2000ft, letting off a HUGE trail right over us! 
Debunkers say they are conventional passenger planes. This cannot be. Passenger planes have a destination. These planes go over and over the same paths. Most are white with no call letters or any identification.
This is just a litle bit of what goes on. Hope to hear more from you. |

| Contrails vs. Chemtrail

I do not think all commercial pilots are participants in the chemtrail phenomena. Normal contrails are still produced by planes flying at altitudes above 25,000 ft, the actual altitude depends on atmosphic conditions in that region. I see planes with normal, short contrails flying in the sky at altitudes above other planes that are producing large "persistent contrails" at the same time. These "persistent contrails" then fan out into artificial looking cloud cover and haze. Numerous times I have seen the chemtrail planes change course, and leave behind U shaped trails. Sure, there are occaisions when a plane will be re-routed due to weather, but how often is the course changed 40 degrees or more (barring inflight emergencies which are rare). Don't you notice the strange looking clouds that look vaguely like shark gills, or sometimes a DNA helix? We're just wondering what's going on. |

No, Spikey's just trying to give you a hard time. Its a fuel dump, probably for an emergency landing or a diverted flight. |

sorry it took so long to get back to the board. i have been gone all week.
thanks for the welcome by the way.
"When flying, say at 30,000 ft., do your instruments give you enough information to enable you to know, with a degree of certainty, that you are creating a contrail?"
the short answer is no. the only indication that would be of any use is something called a "TAT" (total air temp) indication that is on one of our displays. this basically gives us the outside air temperature.
"It seems there is so much concern about persistent contrails having a bad effect on the atmosphere, that they could be eliminated by adjusting the altitude a little"
persistant contrails may very well be a problem. however, "adjusting the altitude a little" is way to simplistic. aircraft are only separated by 1000 ft.
"When you are creating a contrail, what is the normal/average amount of altitude adjustment it would take to eliminate the trail?"
first of all, unless you are in a holding pattern, you have no idea if you or contrailing or not. secondly, there is no way of knowing how much you would have to vary your altitude by. the altitudes that we fly are very strictly controlled, different altitudes depending on which direction you are flying.
"What happened 6 years ago that changed our skies so dramatically? Contrails were extremely rare and normally did not persist. Period."
i am not sure how to answer this as i just dont agree with you. no offence intended. as i stated i have been flying for a long time, i have spent most of my life either in the air or gazing up at it. contrails have increased proportionately with the increase of air travel. one thing that has changed in the last 10 years or so is the dramatic increase of regional jets. these regional jets basically replace most of those prop commuter aircraft that use to be so common. turboprop aircraft generally do not fly high enough to produce contrails, but these "RJ's" fly at the same altitudes of larger jets. |

" I see planes with normal, short contrails flying in the sky at altitudes above other planes that are producing large "persistent contrails" at the same time"
Redeem, why do you think the "short" trails are normal but the large, persistent trails are not? long-lasting, expanding contrails are a well-known and well-documented phenomena.
"hese "persistent contrails" then fan out into artificial looking cloud cover and haze"
once again, this is well known. as a matter of fact, some even believe that this is a contributing factor in global warming.
"Sure, there are occaisions when a plane will be re-routed due to weather, but how often is the course changed 40 degrees or more "
every time that i fly. it happens every flight.
"When an area is getting bombarded AA767, there are planes flying by in many different directions. They leave varying types of trails. Some grow into very wide ones. Some have, on one side of the trail, just the stream while on the other side are many curling off shoots. (hard to explain)
"These planes go back and forth, many, now, have 2 planes flying together. One behind the other. One bigger then the other. One will be spraying one type of trail while the other has a different type."
this doesnt prove anything. your above statement just described normal activity. you say that there are 2 planes flying together. how do you know that they are not separated by 2000 ft, thus flying in different conditions?
"Many of these planes are NOT at a high altitude. One day, coming home from work, this plane could not be more then 2000ft, letting off a HUGE trail right over us!"
i would be very interested in seeing a picture of this. i have seen lots of pictures here but never a picture of a low-flying, chemtrail laying aircraft. |
