New STC to support Garmin GTX 33/32 Mode S/C transponders

A new STC to support the installation of remote mount transponders to the GNS 480 and CNX80 is available. New software

interfaces were added to allow the GNS 480 to interface to Garmin's line of Mode C and Mode S panel mount and remote mount

transponders in v2.0. The GTX 330 and GTX 33 will allow the display Traffic Information Services (TIS) traffic data. The GTX 33

may be remote mounted and will feed both the GNS 480/CNX80 and MX20 displays with TIS traffic data.

The expanding WAAS envelope and selecting WAAS corrections off and on

Currently FAA is adding additional monitoring stations in Alaska, and negotiations are being completed for additional stations in

Mexico as well. The implementation of these stations will greatly increase the size of the WAAS correction envelope to include the

majority of Alaska, Canada, and northern Mexico. It is also expected to cover a large part of the Gulf of Mexico.

To support European, Australian, or other areas outside of WAAS coverage, the ability to manually select WAAS corrections off and

on has been provided. This forces the WAAS engine to revert to a fault detection and exclusion method of determining satellite

health. This has been verified as having resolved the issues associated with WAAS corrections in areas outside the continental US.

If you operate in Europe or other remote areas outside of WAAS coverage, we recommend you select WAAS corrections off to

eliminate any Loss of Integrity messages you might receive.

WAAS and RNP

RNP is something that has been coming along for awhile and will start to affect the National Airspace System (NAS) in the next few

years. If you are not familiar with the term, RNP (Required Navigation Performance) is slated to become a standard for determining

whether or not you can accept a particular clearance for a route or a procedure. For example, if you were to file for an RNAV RNP

airway with an RNP requirement of 5 NM, then you could file for this particular route if you have the primary navigation equipment

necessary and your navigation accuracy is better than 5 NM. Another example would be an instrument approach which would require

an RNP of 0.3 NM or better. There is a direct correlation between these RNP values and the capabilities inherent in the GNS 480.

The plan is to use the GNS 480 on some new airways in southeast Alaska allowing the pilot to file for significantly lower MEA's. In

most cases we're talking about dropping the MEA from as high as 10,000 MSL to 3-4,000 MSL, given the fact that the MEA is no

longer dictated by VOR placement and reception limitations. Only equipment certified to TSO C146a for primary navigation and

meeting the RNP requirements may file for these routes at these MEA altitudes. TSO C129a GPS equipment cannot be used for

primary navigation on these routes. Based upon the success of this new application, additional airways may have their MEA's

adjusted in the continental US, and Garmin GNS 480 customers will be able to take advantage of this. We are in the process of

reviewing the requirements and working with FAA to determine whether the GNS 480 can meet all RNP requirements. We'll keep

you advised of progress in this area, and let you know when you will be able to take advantage of this capability with your GNS 480,

although we expect this to take a year or two for this initial trials to be completed.
