When are flight tracks publicly available?

  • When are flight tracks publicly available? xpda

    Is there a way to make sure a flight is tracked on flightaware.com or similar sites?
    Similarly, is there a way to prevent a flight's track from being available to the public?

  • Skimming FlightAware's FAQs:

    • The most consistent way to show up on FlightAware is to have your flight worked by ATC (a squawk code and an IFR flight plan), or to fly an airplane equipped with ADS-B Out.
    • FlightAware doesn't really track VFR flights unless they have ADS-B Out:

      some VFR aircraft with flight following are available on the position maps but it largely unreliable

    You can block your tail number in a few ways. Both the FAA and FlightAware operate block lists.

  • Sites that track aircraft including FAA 5 minute delayed are Flight Radar 24 and Plane Finder I am also putting up a private tracking network in the Philippines.

    These sites use volunteers that host equipment on an internet connection. Typically these sites will receive Data from Mode S Transponders from up to 200+ miles away with the right aerials. I only need about 6-8 sites to cover the whole Philippines. Line Of Sight limits below horizon reception, so you do need a station close to an airport if you want to get ground traffic.

    If you emit Mode-S then you will be seen. There are no regulations to prohibit that and almost impossible to enforce.

    Anyone can create this setup for less than $30.00, so there is no point in worrying about who is seeing what.

    The FAA so have the ability to hide a specific aircraft, you can request that, but the private networks will report the data.

    There is another technology called MultiLateration that can determine an aircraft's location form 4 or more ground stations with Mode A or Mode C transponders. Flight Radar are actively implementing this in Europe now. It requires a network called PlanePlotter to operate.

  • StallSpin's answer on the recent question about VFR traffic patterns has got me thinking about the "Remarks" section of the Airport/Facility Directory. We are all taught in training to review the AFD entry for airports we intend to visit (part of FAR 91.103's "become familiar with all available information" requirement), and to comply with any restrictions noted - typically things like "no touch-and-go landings", "Standard traffic pattern required of all aircraft", "Prior Permission Required for jet aircraft", etc. Aside from it being The Right Thing To Do, and avoiding the possibility

  • It has been suggested in the media and in some answers here that airlines vary in the information they track about the status of their flights. Is there a publicly available resource that lists what information different airlines have about the location and status of their flights? For example, could a British Airways flight over the Atlantic or the middle of the Pacific have "vanished" in the same way that the Malaysian flight over the Gulf of Thailand?

  • Recently I was checking in to a flight and was asked if I'd like a window or aisle seat as usual and choose a window seat. I was then told that there are no more window seats available but I could get an aisle seat without someone sitting next to me and then just take that window seat. The plane was an ATR-72 so the rows were 2+2 seats. I know about weight distribution to the front/back but I couldn't come up for a good reason to do this. What could be the reason for not giving me that apparently free window seat right away?

  • Here is a $C_L$ / $AoA$ curve that I took from Wikipedia. The better textbooks say that a stall is that condition in which a further increase in angle of attack will result in a reduction of lift. The point at which that transition happens is known as the critical angle of attack. Theoretically, sustained flight is possible at angles beyond the critical angle of attack - take a look at the chart. If the airplane can sustain level flight at point $A$, it can sustain level flight at point $B$. Is there a practical way that I can demonstrate sustained flight on the backside of the lift

  • Pretty straightforward: what is the difference between forward flight, straight flight, level flight, and cruise flight in helicopters?

  • I had posted the question below on a New York Times article, but did not get any useful replies. The series of six successful Inmarsat pings known to exist, MAY carry enough information to say if the plane most likely went along the S or the N arc we see in reports. Unfortunately, only the last ping (at 8:11AM) is available publicly. Here is the basic idea on extracting the information..., of course) giving us a series of most likely positions at 3:11AM, 4:11AM, 5:11AM, etc. If the trajectory of these sequence of spaces has a N/S directionality, we can say with some confidence

  • How much the pitch (horizontal orientation) can differ from the angle of attack? I am trying to understand the claim that "angle of attack indicator was unfortunately not available", contributing to problems during Air France Flight 447. Attitude indicator most likely was available?

  • The answer for How does wind affect the airspeed that I should fly for maximum range in an airplane? refer to a velocity/power-required curve. As far as I can tell, this curve can't be deduced from information in the flight manual. I suppose one could experiment and determine what power setting is required in order to maintain level flight at a bunch of airspeeds. (Or for a glider, record the sink rate, which is proportional to the negative of the power-required, at a bunch of airspeeds.) Would that be accurate enough? Are these curves available from the manufacturer?

  • Where can I find nice flutter animations/videos (other than YouTube) to add to a presentation without violating Copyright regulations ? It can either be for wings as well as blade arrays. Are you aware of any OpenSource database on this topic ?
