    There is a lot of confusion around what it means to have ADS-B. What is the minimum equipment required to meet the mandate? Can I use a Stratus to meet that requirement?

  • The short version is no the Stratus will not meet the requirements, and for several reasons.

    The final rule requires ADS-B OUT (and the Stratus is only ADS-B IN) that meets particular TSO requirements (see below), and portable units will not.

    The FAA has an ADS-B FAQ on their website which has a lot of great ADS-B information.

    The minimum equipment required to meet the mandate is addressed by:

    What equipment is required by the new rule?

    The rule specifies ADS-B Out equipment compliant with either Technical Standard Order (TSO)-C154c (Universal Access Transceiver) or TSO-C166b (1090 ES). However, to operate in Class A airspace, aircraft are required to equip with avionics certified to TSO-C166b.

    The FAQ also specifically addresses the question of portable units and says that they will not be allowed:

    Will the FAA allow portable/handheld units, or will they have to be panel mounts only?

    Installed transponders and GPS units must meet certification standards. Handheld devices and displays that serve only for situational awareness have more flexibility and are not certified installations. In order to comply with 14 CFR ยง 91.225 and 91.227 aircraft intended to fly in ADS-B airspace must have installed and certified equipment. Portable installations are not compliant to the rule and would only be usable for receiving FIS-B services for situational awareness. The FAA is in the early stages of investigating a portable device for glider aircraft.

  • While reading the description of ADS-B given on the FR24 website (ADS-B How it works), I came across this sentence: The farther away from the receiver an aircraft is flying, the higher it must fly to be covered by the receiver. What is the relation between height and coverage in this case?

  • I noticed that no planes heading to FMMI are ploted on all the prominent online radars despite the fact that most of them are likely equiped with ads-b. What does it take to remedy that lack of coverage?

  • I was looking through my virtual radar logs one of the days and found this "glitchy" ADS-B behavior. I am almost 100% sure that this is not due to my antenna or setup since two independent different radars confirmed this weird behavior from FlightRadar24. Also A/C before and after this one did not exhibit this behavior. Does anybody have any thoughts as to what may be happening??? Why... of occurrence is approximately: 3/16/2014 6:09pm CST I have also verified FlightAware is ALSO showing the same weird glitch. See below "yellow" highlighted airplane: Same A/C from FlightRadar24

  • What is the average range, accuracy, and update frequency of radar systems used to monitor airspace in the USA? I'm primarily interested in capabilities for tracking smaller general aviation aircraft without enhanced return data channels like ADS-B, etc. Please include sources, if possible. As an example, by looking at TRACON/ASR data exports (CDR), these systems appear to update an aircraft echo at about a 4.7 second frequency, give or take a few tenths. However, I not been been able to source or verify my findings or similar statements made by expert witnesses in litigation cases.

  • Reading the requirements for MEL it is confusing which things must be done in a multi-engine, and which things carry over from SEL. If I already have SEL do I need to do a cross country in a multi-engine? Assuming I can meet the PTS for MEL, what other requirements are there?

  • I read that ADS-B is required by the year 2020. What does this mean? What is ADS-B used for, and who needs it?

  • Aircraft which have been in service for a long time often have a lot of entries in their logbooks for Airworthiness Directives (ADs). What are they, and why are they important?

  • There are more experimental class aircraft in the USA than any other. That being said, what type of requirements does an experimental aircraft have to meet. Also, are there ways around certain regulations? For example, the guy in the picture below was battling with the FAA so they would let him fly his jet pack in the USA over the grand canyon, which they originally said no to, but they eventually let him - is this because he is "famous" and therefore has less rules he needs to follow?

  • In this question, the answer notes that some ADS-B systems are connected to Inertial Navigation Systems (INS), and says they are less accurate than GPS. What exactly is an INS? A couple sub questions: Why is it less accurate? The other post mentions they tend to develop biases as they get older, why is that? Are they being phased out? Or are they used as backup?
