250 kts bellow 10K
The origins of this regulation had nothing to do with bird strike protection because when the regulation was put in place in the early 50's who cared or was a bit concerned about bird strikes? think about it, your flying along in a tank like built DC6, DC3 or Connie and a bird strike was a non issue, but for an air traffic controller working without radar and in a congested airspace where most of the traffic wasn't going farter than 200kts. because after all, jets where a new thing in the 50's. Then the explosion of general aviation during the 60's and 70's brought the "Indian" phenomenon that somebody mentioned in an earlier post and again 250 bellow ten played a part in organizing traffic. All jets that I know of have a higher speed for bird strike protection than 250 bellow ten and all birds that pose a real danger because of their size (large migrating waterfowl for example) they all fly a lot higher than 10K. so the common sense argument of the original post is flawed. So if you are departing out of an airspace that has no speed restriction, please use your common sense and remember that the A/C taking off 45 seconds behing you is going to accelerate
