2.11 Barometric Setting

The barometric altimeter setting used for any barometric corrected altitude

source interfaced to the GTN must be set appropriate to the altitude type

depicted on the procedure (QNH or QFE).

This STC does not grant operational approval for RF leg navigation for those

operators requiring operational approval. Additional FAA approval may be

required for those aircraft intending to use the GTN as a means to provide RNP

1 navigation in accordance with FAA Advisory Circular AC 90-105.

The following limitations apply to procedures with RF legs:

Aircraft is limited to 180 KIAS while on the RF leg

RF legs are limited to RNP 1 procedures. RNP AR and RNP <1 are not

approved

Primary navigation guidance on RF legs must be shown on an EHSI

indicator with auto-slew capability turned ON

GTN Moving Map, EHSI Map, or Distance to Next Waypoint

information must be displayed to the pilot during the RF leg when

flying without the aid of the autopilot or flight director.

The active waypoint must be displayed in the pilot's primary field of

view.

The flight crew may fly all phases of flight based on the navigation information

presented to the flight crew; however, not all modes may be coupled to the

autopilot. All autopilots may be coupled in Oceanic (OCN), Enroute (ENR), and

Terminal (TERM) modes.

This installation is limited to:

Lateral coupling only for GPS approaches. Coupling to the vertical path for

GPS approaches is not authorized.

It is possible to create flight plan waypoint sequences, including Search and

Rescue patterns, which exceed the autopilot's bank angle capabilities. The pilot

shall monitor autopilot performance with regard to flight path deviation.

2.13.1 RNP 1.0 RF Leg Types

AC 90-105 states that procedures with RF legs must be flown using either a

flight director or coupled to the autopilot.

This STC has demonstrated acceptable crew workload and Flight Technical

Error for hand flown procedures with RF legs when the GTN installation

complies with limitation set forth in Section 2.12 of this document. It is

recommended to couple the autopilot for RF procedures, if available, but it is
