Garmin Aviation GPS

120-Day JA Air Center Warranty!

The GPSMAP 296 builds on the tradition of Garmin aviation handhelds like the GPSMAP 196 and GPSMAP 295. New features like terrain cautions and alerts, sectional chart-like topographic data, a built-in obstacle database of the U.S., and a transparent navigation arc view for course, speed, and distance information lead the list of advances. The GPSMAP 296 also features USB data transfer, faster processing speed, and a rechargeable lithium-ion battery pack. Press a button, and you have your choice of the unit's automotive or marine modes.

Garmin delivers terrain awareness in an intuitive Terrain mode on the GPSMAP 296. The unit combines GPS position, GPS altitude and topographical mapping to give pilots a vivid depiction of potential terrain hazards.

Pilots gain terrain awareness in a number of ways:

Terrain and obstacle information
By using visual cues and tone alerts, pilots can be aware of potentially dangerous terrain or obstacle conflicts along the current flight path. The unit also offers a configurable look-ahead warning function which gives the pilot additional time to make critical decisions.

Configurable buffer zones
The pilot can set the minimum limits to receive terrain cautions. The unit then presents potential hazards in yellow (to indicate ground proximity of 500-1000 feet) and red (to indicate ground proximity of 100 feet or less).

Obstacles database
Users can view the elevation or relative altitude of any obstacle (towers, buildings, etc.) within the unit’s built-in database. (This feature is only available with the Americas version.)

Pop-up alerts
Terrain proximity cautions and alerts pop up as digital thumbnail images in the lower left-hand corner of any page whenever a potential hazard conflict looms ahead.

History of Avionics

The term avionics was not in general use until the early 1970s. Up to this point instruments, radios, radar, fuel systems, engine controls and radio navigation aids had formed individual (and often mechanical) systems.

In the 1970s, avionics was born, driven by military need rather than civil airliner development. Military aircraft had become flying sensor platforms, and making large amounts of electronic equipment work together had become the new challenge. Today, avionics as used in military aircraft almost always forms the biggest part of any development budget. Aircraft like the F-15E and the now retired F-14 have roughly 80 percent of their budget spent on avionics. Most modern helicopters now have budget splits of 60/40 in favour of avionics. (F-22?)

The civilian market has also seen a growth in cost of avionics. Flight control systems (fly-by-wire) and new navigation needs brought on by tighter airspaces, have pushed up development costs. The major change has been the recent boom in consumer flying. As more people begin to use planes as their primary method of transportation, more elaborate methods of controlling aircraft safely in these high restrictive airspaces have been invented. With the continued refinement of precision miniature aerospace bearing, guidance and navigation systems of aircrafts have become more exact.
