FAQs

What are the differences between the Stormscope® Models?

The Series I Stormscope captures storms using the amplitude of the 50 kHz component of the lightning strike. The WX-1000 series uses several aspects of the 50 kHz component (rise time, fall time, pulse width, etc.). The WX-900, 950 and 500 look at the same aspects of 11 different frequencies to range the strike. In addition, the WX-500 and 950 have a “CELL” mode and a “STRIKE” mode. The Strike mode displays the strike similar to the Series I (with radial spread) and the Cell mode uses a more accurate method of ranging the strike.

Where should the Stormscope® antenna be mounted?

The Stormscope is looking for lightning, which is huge discharges of static electricity; therefore, the location of the antenna is critical to its proper operation. All L-3 Avionics Systems dealers have a piece of test equipment called a “Skinmapper” which will help in locating the exact location for the antenna to be placed. This location could be critical by inches, so we require the dealer to skinmap on every installation.

Where can I send my Stormscope® to be repaired?

Do you still sell/service J.E.T. gyros?

Although our name has changed in recent years, we still offer the same quality products and services. Some of our most popular product lines include: JET and AIM Gyros, Stormscope® Weather Mapping Systems, SkyWatch® Collision Warning Systems and LandMark™ Terrain Awareness and Warning Systems.

How does LandMark™ TAWS8000 use the database?

The TAWS8000 is a terrain awareness and warning system that has predictive, look ahead capabilities. It uses GPS position and velocities along with aircraft altimetry to predict future aircraft 3D position. This position is compared against the terrain elevation database to predict potential ground impact. In a similar fashion the TAWS looks into the database for conflicts with obstacles. It also looks up runways to prevent nuisance alerts when landing.

What information is contained in the TAWS database?

The TAWS8000 datacard includes terrain, obstacle, runway databases and magnetic variation information. Using this data, the TAWS8000 displays unique symbols for obstacles, graphical depictions of runways (more than 2000 feet long) and an enhanced terrain depiction, using seven shades of color for superior contouring effects.

• Jeppesen provides terrain and NavData runway information
• The FAA provides obstacle information
• NOAA provides magnetic variation tables

Do I need an RMA number to return a unit in for service?

No, only if the unit is new and has never been installed in an aircraft.
