As the names imply, these are simply different frequencies used by the equipment to transmit and receive data. This is the only technology accepted outside the US and above 18, feet, so it will be popular with turbine airplanes.
ES receivers can detect other aircraft with ES transmitters air-to-air, and they can receive other traffic information uplinked from ADS-B ground stations. But there is no weather datalink on This is only available in the US, and only below 18, feet, so it is aimed mostly at piston aircraft. But weather is also transmitted over MHz, an added bonus. This ends up being a real mess. At the end of the day, you should choose the Out frequency that matches your flying.
If you fly above 18, feet or outside the US, ES is your only option. There is no monthly subscription fee with FIS-B your tax dollars paid for it , which is a nice feature. That means coverage, while pretty good now and getting a lot better, is not as universal as XM. But leave it to the FAA to make this complicated. Read this article for complete details on this confusing subject. A lot of this seems awfully optimistic, and will not be a reality for many years if ever.
But there are some more realistic improvements that will probably come to pass sooner. Since ADS-B is so much more accurate than radar, separation minimums can be reduced.
This should lead to at least a little more direct routing and some increased capacity. Because ADS-B does not require radar, air traffic control will be available in many remote areas that cannot be served by radar. ADS-B will also impact ground operations, giving controllers the ability to prevent runway incursions and ground traffic conflicts.

Views: 2, What do you need to know? Within 30nm of Class B Mode C veil. What are the ADS-B rules in the rest of the world? Let us know! Brent Fishlock. One Comment. Michael says:.

Phase 2 will start on MAR ADS-B is required to operate from FL to FL inclusive within a specified area that will affect the following airway segments listed below.
A second phase to begin on December 31st, , will extend this requirement all the way to the surface. Then on January 27th, will expand into Class B airspace. Non-ADS-B Out equipped aircraft will be accommodated within the airspace until a performance requirements mandate can be implemented. As per U. On JAN, this requirement will extend all the way to the surface. Be sure you have the correct version to operate where you are going.
Know which codes apply to the specific operation. Remember that codes filed in the FPL should represent not only aircraft equipment and capabilities but also those crew members covered by necessary training, authorizations from state of registry, and working equipment.
Many ADS-B mandates will come into force in Remember that even though some countries do not currently have any ADS-B mandates or any proposals for mandates, there is still quite a bit of ADS-B coverage out there. Those aircraft not equipped with ADS-B can still potentially run into situations as you are less equipped than those around you.
