Hi all,



Today I had an email from the FAAsafety.gov site talking

about ADS-B availability in the KMSP area, which I've of

course noticed for quite some time.  So I'm not sure if

it's finally "official" or what, but, it did give some info

and a pretty nice link to a gov't website on ADS-B, so I

thought I'd put it here for you to see.

Attached are a couple of coverage related screenshots...The

map that shows coverage zones shaded is pretty poor on

accuracy from what I've found, because I've had coverage

in lots of those areas that show no coverage.  But, if

you compare it to the ground station map, you'll see that

some areas like Arizona and SoCal are filled with stations,

so there really is coverage there.  Anyway, thought some

of you who routinely ask me coverage questions might like

to see this stuff.

Tim

ADS-B in the Minneapolis Area

Notice Number: NOTC2960



Attention All Pilots Flying in the Minneapolis En Route AirspaceNew 

Traffic and Flight Information Services Are Available Now

Pilots who fly in the Minneapolis En Route Airspace (ZMP) can now 

receive free traffic and weather information in the cockpit. To receive 

these services, aircraft must be equipped with an Automatic Dependent 

Surveillance - Broadcast (ADS-B) transmitter/receiver or transceiver and 

a cockpit display of traffic information (CDTI).A map showing the 

coverage area is available at: http://www.faa.gov/nextgen/flashmap/.

The new services include:



Flight Information Service - Broadcast (FIS-B), which provides pilots 

and flight crews with a cockpit display of aviation weather and 

aeronautical information via Universal Access Transceiver (UAT) 

equipment on 978 MHz.Note:FIS-B is not compatible with 1090ES avionics.

·The following FIS-B weather products are for advisory use only.The 

information provided by FIS-B can not be used in compliance of any 

regulatory requirement.Pre-flight weather briefings and in-flight 

weather updates must be obtained through FAA approved sources only.

oAviation Routine Weather Reports (METARs).

oSpecial Aviation Reports (SPECIs).

oTerminal Area Forecasts (TAFs) and their amendments.

oNEXRAD (regional and CONUS) precipitation maps.

oNotice to Airmen (NOTAM) Distant and FlightDataCenter.

oAirmen’s Meteorological Conditions (AIRMET).

oSignificant Meteorological Conditions (SIGMET) and Convective SIGMET.

oStatus of Special Use Airspace (SUA).

oTemporary Flight Restrictions (TFRs).

oWinds and Temperatures Aloft.

oPilot Reports (PIREPS).

oTIS-B service status.

Traffic Information Service - Broadcast (TIS-B),which enhances a pilot's 

visual acquisition of other traffic on 978 UAT and 1090 MHz Extended 

Squitter (1090 ES).

·TIS-B is an advisory only service.Pilots must continue to exercise 

vigilance to “see and avoid” other aircraft in accordance with Title 14 

of the Code of Federal Regulations Section 91.113b.

The following table lists which type of data link is required to receive 

TIS-B and FIS-B services:



If the aircraft is equipped with the following data link…

Then the pilot can receive the following services…

978 MHz Universal Access Transceiver (UAT)

TIS-B and FIS-B

1090 MHz Extended Squitter (1090 ES)

TIS-B



The FAA encourages users of TIS-B and FIS-B to report any irregularities 

observed while using the services. Reports should contain the following 

information:

1.Time of observation.

2.Location.

3.Type and identity of the aircraft.

4.Description of the condition observed.

5.Type of avionics system and software version used.



You can report issues by contacting the nearest Flight Service Station 

(FSS) facility or by submitting FAA Form 8470-5, Safety Improvement 

Report, available from FSSs, Flight Standards District Offices, or 

general aviation fixed-based operators.

Additional information about ADS-B services can be found in the 

Aeronautical Information Manual at the following link:

Thanks Tim.



I love the disclaimer. Apparently FAA weather (METARs and TAFs) obtained thru an FAA source (ADS-B) cannot be used to satisfy FAA regulatory requirements!



I can hear all the conversations with FSS/ Flight Watch now: "Well, we've got the Notam and TAF for our destination, but it doesn't count and we need to hear it from you" (!)

Nah, the source is the FAA approved source....but I bet they're worried about how up to date your data is, because ground level coverage will be poor, so much of the data wouldn't be available until airborne for many people, and won't be available airborne until you're high enough, in other areas, sometimes as high as 5000-18000ft.

That's the problem with ground based weather, and why I feel for the dedicated traveler, satellite based WX is always the better choice.  

These days though, for every bit of data, everyone is all "CYA" and put disclaimers on everything.
