Flight 21 ADSB ? What is it?

[AdamZ]

I was checking out Newport News Airport for a trip to Williamsburg and the Airports web site indicated they had something called " Flight 21 Automatic Dependant Surveillance Broadcast. The FAA's website did a very poor job explaining what this is. Can anyone explain it to me?

Steve I saw the site but I can't get in. What is the ADS B?

My understanding is that it will broadcast the information to those aircraft which are equipped to receive that information. I do not know if it broadcasts weather info, but I am pretty sure it broadcasts the actual radar traffic information. What this means is that if you are equipped with the proper equipment in the aircraft you should be able to get a pretty good idea of the traffic situation.

But don't ask me to back any of this up with cites as this was a quick memory dump.

Each equipped aircraft broadcasts it's location, altitude, and speed. Other equipped aircraft, and ATC, receive the information, and display it in the cockpit, giving you your own little ATC display. It works independently of the ATC system (hence the name) and works without radar, and without ATC for that matter, if need be. If all airplanes ever get equipped with these, we'll have removed the need for ATC radar.

FIS, Flight Information Service, is a rebroadcast of ATC radar, and also weather information. It seems quite a bit more limited to me.

...and we won't have anymore no-electrical system Cubs, etc. flying...losing a lot of our aviation heritage. I vote to keep the guys behind the glass screens, and for pilots to keep their eyes out the windows. Technology has a place, to a point, but I don't want the FAA telling me I have one year to come up with $20,000 for a new piece of avionics if I want to fly within 30 nm of a Class-B hub.

I don't see why ADS-B, and/or the demise of ATC radar, would cause the disappearance of Cubs and the like. I doubt those planes show up all that well anyway as just a primary return. Regardless, I can see the day coming, fairly soon, when non-electrical system planes and others not properly equipped are barred from Class B airspace. I can see the day coming even sooner when non-ADS-B planes are barred from the Washington ADIZ.

In addition to providing GPS-precise aircraft location data to ATC, ADS-B can also uplink weather (text and radar images) and traffic data to be displayed in the cockpit as well as terrain avoidance information. The FAA says it's very much the future of ATC in terms of transferring information between the cockpit and the ATC system. You need a special data link transceiver (like the Garmin GDL 90) and a display system (like the MX-20). Try that link again, as it is working, but be warned that the ADS-B Primer document is over 6 mb to download.

We used PHF for our trip to Williamsburg last thanksgiving. Good place. We were going to go to JGG but the weather was pretty close to minimums there. So, at the last minute, we changed our rental car reservation to Newport News and shot the ILS there. It is a nice little Class D with good service and a pleasant little FBO. They won't let you come to/from your plane by yourself, but they send a van out right away and they will escort you and your rental car through the gate and right up to the plane to load it on the hitch out. The local car rental agency was out of a Caddy dealership, and the FBO dropped us off there.

We had a front through during the week and the plane was securely tied down and safe during it.

All in all we were quite satisfied with the service. Don't remember what fuel prices were, but I always figure they are what they are. You know?
