FREE FLIGHT TRA 3000 RADAR ALTIMETER / INDICATOR
|
 |
The TRA 3000 Radar Altimeter, combined with the TRI40 Radar Indicator,
provides precise AGL information from 2,500 feet down to 40 feet. This
real-time system offers an extra measure of operational safety during
landing, navigation, and hovering. It is especially useful in flying
search and rescue missions, forestry operations, pipeline maintenance,
offshore helicopter operations, aeromedical emergency medical services,
border patrol, and electronic news gathering operations. The transmitter
/ receiver and antenna fit in a single lightweight & aerodynamic
unit that is easy to install. |
