Especially when I can contract it out to my future employer! Plus I get to fire all those darn air traffic controllers. Just so long as the midairs are between airliners with the hoi polloi inside and not the biz jets that I fly, we're A-Okay!DisgruntledFlyernoreply@blogger.comtag:blogger.com,1999:blog-1509900465677846838.post-12897021476703222732010-02-25T18:53:53.538-05:002010-02-25T18:53:53.538-05:00I was a controller at ZAU and ZMP, total 21 years ...I was a controller at ZAU and ZMP, total 21 years on the boards. NRP means Not Really Pertinent. I would mention to pretty much everybody in my airspace that direct routing was available and whoever asked got as far as they wanted directly. This was my way of promoting Free Flight, helping the user, getting the A/C on their way and out of my sector. Some of those higher-ups in the FAA support this thinking. Some don't, especially those that want to think they still have a say about controlling A/C, albeit from a desk writing rules in a book.<br /><br /> The folks who did not give directs usually kept flights on the hiways in the sky and usually got tubed trying to give 1 plane a 4000' altitude change because EVERY plane was on the same friggen airway.<br /><br /> Having worked an arrival sector at ZAU I understand the need for lining up flights a good distance from the approach boundary. I recognize the need for following a rigid proceedure. Away from that, let 'em rip! I got paid good money and am now enjoying retired life because I could keep them apart, both rigidly lined up in congested space and flying direct away from the crowded spaces.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1509900465677846838.post-5845864134294546032010-02-25T00:41:26.242-05:002010-02-25T00:41:26.242-05:00"There can be a million reason for a differen..."There can be a million reason for a difference in en-route times."<br /><br />The direct-ness of it isn't generally the deciding factor. That is my only point. <br /><br />From an ATC standpoint at ZBW, we don't shortcut NRP flights. Also, if airlines are flying northerly eastbound routes, the UCA sector will work ALOT more airplanes. <br /><br />Other than that, that's it.deltamike172https://www.blogger.com/profile/03440111329857048591noreply@blogger.comtag:blogger.com,1999:blog-1509900465677846838.post-72142637818900796642010-02-25T00:08:45.284-05:002010-02-25T00:08:45.284-05:00I was hoping for more from this blog post. As an ...I was hoping for more from this blog post. As an airline dispatch that files NRP as often as possible, I was hoping to learn how that impacts your job as a controller.<br /><br />There can be a million reason for a difference in en-route times. The B757 tends to cruise faster than the A320/319. <br /><br />Most airlines don't dispatch with the quickest enroute time, instead they dispatch based on the cheapest route. There is a lot of facts that influence costs. Planning a slower burn to save fuel costs. Flights over Canada get charged overfly costs, while staying in US airspace is free. The fix cost of operating a plane an hour aka crew, maintenance, insurance, lease. The long the plane is in the air, the more it costs. Sometimes its cheaper to burn more fuel to fly faster because of that. Luckly we have computers that figure it all out for us.Jonnoreply@blogger.comtag:blogger.com,1999:blog-1509900465677846838.post-55285742016485788902010-02-24T23:46:04.521-05:002010-02-24T23:46:04.521-05:00I know there are other unmentioned variables, incl...I know there are other unmentioned variables, including the financial state of an airline and how slow it flies to save gas. <br /><br />My point is that "the current system is outdated because planes have to fly longer routes from VOR to VOR" isn't the problem. Our solution is also already in effect and not always used. <br /><br />How can the system be designed so that EVERY company can fly how they want and not get in someone else's way? <br /><br />Thanks for reading!deltamike172https://www.blogger.com/profile/03440111329857048591noreply@blogger.comtag:blogger.com,1999:blog-1509900465677846838.post-5382967963507356642010-02-24T23:34:44.984-05:002010-02-24T23:34:44.984-05:00There are a million variables.
