wrote in : http://www.alaska.faa.gov/ata/MACA.htm PROPER CLEARING/SCANNING TECHNIQUES An efficient scan pattern is paramount to visual collision avoidance procedures. In developing a proper scan technique, remember that when your head is in motion, vision is blurred and the brain will not be able to identify conflicting traffic. Therefore a constant motion scan across the windscreen is practically useless. A proper scan technique is to divide your field of vision into blocks approximately 10 to 15 degrees wide. Examine each block individually using a system that you find comfortable (e g. from left to right or starting from the left and moving to the right, then back to the left again). This method enables you to detect any movement in a single block. It takes only a few seconds to focus on a single block and detect conflicting traffic. A moving target attracts attention and is relatively easy to see. A stationary target or one that is not moving in your windscreen is very difficult to detect and is the one that can result in a MIDAIR COLLISION. The time to perceive and recognize an aircraft, become aware of a collision potential and decide on appropriate action, may vary from as little as 2 seconds to as much as 10 seconds or more depending on the pilot, type of aircraft and geometry of the closing situation. Aircraft reaction time must also be added. By the way, any evasive maneuver contemplated should include maintaining visual contact with the other aircraft if practical. There you have it. The FAA telling pilots, that for a 90 degree wide scan field (45 degrees each side of center), it takes more than two seconds per 15 degree scan block (at 3 seconds per block, that's 18 seconds per full scan), for a pilot to see a stationary traffic conflict aircraft growing larger, and it can take up to ten seconds see-and-avoid (for a total of 28 seconds per full scan). |

Every flight, every day, by the military is on a flight plan.
Even those flights on VFR MTRs? Yes. Does ATC track those flights in real time, at least with non-radar position reporting? If so, then ATC should be able to provide better information that a civilian pilot could use to determine whether or not to transition a route at a particular point at a particular time.

Even those flights on VFR MTRs? Yes. Then why are there IFR MTRs and VFR MTRs? Because some can be flown in visual conditions and some can be flown in instrument conditions as well. Regardless of weather conditions, IAW regulations all military flights are conducted on an IFR flight plan ("to the maximum extent practicable" -- which is regulation-speak for all of them). A "flight plan" is merely a record of your intended route of flight--it can be a VFR or IFR flight plan. Flight plans are filed with Flight Service Stations--an entity of the FAA, but not an air traffic controlling agency. Regardless, the flight plan type for the military is IFR. (I use the term "military" with some trepidation as I do not know if Army rotary wing craft do that.) You really don't know a lot about this do you? Yet, you are steadfast in your opinions.

If so, then ATC should be able to provide better information that a civilian pilot could use to determine whether or not to transition a route at a particular point at a particular time. See the post to LD regarding what a flight plan is. Departures are conducted under ATC. Recoveries are conducted under ATC. Training time along an MTR, within a MOA, in restricted airspace, or on a range is usually done without ATC involvement. If your hypothetical civilian pilot wants ATC to provide him safe separation from other IFR aircraft, he/she should file an IFR flight plan, obtain an IFR clearance, and operate in controlled airspace under ATC's control. They should also look out the window as best they can. Ed Rasimus Fighter Pilot (USAF-Ret) "When Thunder Rolled" www.thunderchief.org www.thundertales.blogspot.com |

Jose When I was an air traffic controller at the Denver Enroute Center we would get a flight strip for, say, a B-52 entering a MTR. It's been a while but the flight strip would have his entry time for the MTR and a calculated exit time along with the altitude he'd be climbing to at the exit point. We didn't track him at all while he was on the route; he wasn't on radar and, given the nature of an MTR, it would be nearly impossible to give a civilian pilot an accurate position report of the B-52. It's been several years since I've been a controller so things may have changed. --Walt Weaver |
