400/500 SERIES FDE PREDICTION INSTRUCTIONS

NOTE: These instructions assume the user has experience operating the applicable 400/500 Series Unit and is familiar with the operation of RAIM. The figures in this addendum are derived from the 400/500 Series units. The information in this document applies to all 400/500 units unless otherwise stated.

FAULT DETECTION AND EXCLUSION (FDE)

The GARMIN 400/500 Series Main and GPS Software version 3.00 and higher (Figure 1) incorporate Fault Detection and Exclusion (FDE) display interface and control, satisfying the requirements for “GPS as a Primary Means of Navigation for Oceanic/ Remote Operations” per FAA Notice N8110.60.

FDE consists of two distinct parts, fault detection and fault exclusion. The fault detection part detects the presence of an unacceptably large pseudorange error (and presumably, position error) for a given mode of flight. Upon the detection, fault exclusion follows and excludes the source of the unacceptably large pseudorange error, thereby allowing navigation to return to normal performance without an interruption in service. To enhance safety, FDE functionality is provided for other phases of flight (non-precision approach, terminal, en route). The FDE functionality for non-oceanic flight phases adheres to the same missed alert probability, false alert probability, and failed exclusion probability specified by N8110.60.

The following 400/500 Series Units are affected:

•GPS 400

•GNC 420/420A

•GNS 430/430A

•GPS 500 (TAWS)

•GNS 530/530A (TAWS)

PRE-DEPARTURE VERIFICATION OF FDE

An FDE prediction must be performed prior to departure for a flight plan involving:

•Oceanic/Remote operation where GPS is to be the sole source of navigation per FAA Notice 8110.60

•U.S. Area Navigation (RNAV) routes, Standard Instrument Departures (SIDs), or Standard Terminal Arrival Routes (STARs) if a NOTAM indicates a GPS satellite (or satellites) is scheduled to be out-of-service, per FAA AC 90-100 “U.S. Terminal and En Route Area Navigation (RNAV) Operations”

Prior to departure, the operator must use the FDE Prediction Program supplied with the 400/500 Trainer Software to demonstrate that there are no outages in the capability to navigate on the specified route of flight (the FDE Prediction Program determines whether the GPS constellation is robust enough to provide a navigation solution for the specified route of flight).

400, 500 specifications

The Garmin 500 and 400 series of devices are highly regarded in the world of GPS navigation and fitness tracking. These models have been designed to cater to various needs, making them popular among outdoor enthusiasts, athletes, and everyday users alike.

The Garmin 500 series, particularly the Edge 500 model, is an advanced cycling computer that comes equipped with a multitude of features geared toward cyclists. One of its standout characteristics is its robust GPS capability, which allows riders to track their speed, distance, elevation, and time. The device has a built-in accelerometer that aids in tracking performance metrics, providing valuable insights into ride efficiency. It is also capable of recording data points like heart rate and power output when connected to compatible sensors, which is essential for serious cyclists looking to refine their performance.

On the other hand, the Garmin 400 series is known for its versatility in navigation across multiple outdoor activities. The GPSMAP 400 series provides dependable marine navigation for boaters and fishing enthusiasts. It features a high-sensitivity GPS receiver, ensuring accurate location tracking even in challenging environments. With its color display and user-friendly interface, navigating through complex waterways becomes seamless.

Both the Garmin 500 and 400 series come equipped with cutting-edge technologies, including GLONASS support, which increases satellite acquisition time and accuracy in dense urban environments or wooded areas. The Ant+ connectivity feature is another highlight, allowing seamless pairing with various sensors like heart rate monitors, speed and cadence sensors, and power meters - crucial for cyclists and fitness enthusiasts.

In terms of battery life, both device series offer impressive performance, with the Edge 500 lasting up to 18 hours on a single charge and the GPSMAP 400 offering long-lasting power for extended trips on the water.

In conclusion, the Garmin 500 and 400 series are prime examples of modern GPS technology, with each series tailored to meet the specific needs of cyclists and outdoor adventurers. Their array of features, solid build quality, and connectivity options make them indispensable tools for optimizing performance and ensuring safety on the road or at sea. Whether you are looking to enhance your cycling game or navigate waterways with confidence, these devices offer unparalleled performance and reliability.
