OUR OPINIONS ON WEATHER RADAR
AVIONICS
Brought to you by
APG - Eastern Avionics International
According to the National Transportation Safety
Board, well over 200 fatalities have been attributed to thunderstorm-related
accidents over the past five years. Many of these accidents could have been
avoided if the aircraft were equipped with weather radar or stormscope systems..
Today, there are few valid excuses for not having one of these
systems aboard your aircraft. The cost has come down dramatically on new units
and some reconditioned systems can be had for well under $2,500. The best
models integrate navigation, course plotting and checklist information on
the screen along with weather data. This gives you features and information
useful even in CAVU conditions.
Whether you choose WX radar, Stormscope, or DataLink options
is a matter of the type of aircraft you fly and what features are important
to you. If you own a single engine or light twin engine aircraft, Stormscope
and DataLink are your best options. Stormscopes keep you aware of potentially
dangerous weather by measuring the electrical activity associated with convective
wind sheer and turbulence. DataLink Weather is fantastic for strategic decision
making when flying.
Your options are much greater with a medium twin or larger aircraft
because weight is less of a factor, a fiberglass nose or radome may already
be in place, and more panel space is usually available. Only Radar can steer
you clear of precipitation and give you ground mapping capability. Certainly,
the best choice is to have both Stormscope, DataLink and Radar installed.
At APG-Eastern Avionics International, we can offer you a wide variety
of Radar, Stormscope and Weather DataLink systems, reconditioned and new,
to satisfy almost any budget. All of our systems are priced complete with
antennas and connectors. Just give us a call -- we'd be happy to install one
in your aircraft!

Sperry/Honeywell PRIMUS 300SL Slim-Line Series Color Radar System. DI-2007, RT-3002, AP-3001 (Reconditioned System)
$15,995.00 $13,389.00 On Sale!
The Sperry/Honeywell Primus 300SL color weather radar system is a compact, gyro stabilized weather radar we commonly install in turboprops through medium-sized business jets. With well over 2,000 systems flying, this radar has proven itself over the years for extremely high reliability. This system gives you all the advantages of a multi-color display with a fu1l 300nm range, at the lowest cost in the high-end series. Like all the hi-line Primus models the system uses positive pushbutton controls, selectable azimuth marks, cyclic contour, target alert and Data Nav display capability. Weather is displayed in red, yellow and green, while groundmapping appears in magenta, yellow and blue. This six-color system is great for quick interpretation and can be easily seen, even in bright sunlight. The 300SL has internal multifunction display capability. When you add the Data Nav Display System, the Primus 300SL radar becomes an enroute navigation display with waypoints, intended course and track lines, ground speed and LAT/LON information displayed on the screen. The electronic checklist option accesses up to 200 pages of normal operation and emergency procedure checklists. You also have extended contour range to give the real weather picture at maximum ranges, dual pulse width and band width for excellent short range resolution and maximum long range performance, and a super-efficient 10", 12" or 18" flat-plate antenna with gyro stabilization. The Primus 300SL indicator is very easy to use and understand. All function controls are on the indicator panel, and are laid out for safe, non-confusing operation. This compact color unit has been "human-engineered" to permit quick and accurate use by operators, especially during periods of deteriorating weather when the radar is most needed. There's also no compromise on quality in the display itself. The bright, six-color picture has the highest possible resolution while a neutral density filter provides bright, clear and easy interpretation. A mode annunciator with range identification, azimuth lines and target alert add that extra edge of safety. Instant recognition of the weather situation is possible with storms analyzed and displayed in three bright colors. 1ight rainfall in bright green, medium rainfall in yellow and heavy rainfall in red clearly warns of precipitation and associated turbulence ahead. With the Primus 300SL radar, weather looks realistic. Because of its high resolution, the system shows weather with smooth rounded edges, clearly showing hooks and scallops. In this way, pilots get a picture that looks familiar, one that can be clearly understood. With its own set of three colors, the groundmapping mode presents coastline, ground shapes, rivers, lakes and cities almost as they would appear on a map. Mapping information is displayed in colors distinct from weather. The weak returns are shown in blue, medium in yellow and strong returns in magenta. The Primus 300SL radar uses a narrow pulse width in the mapping mode to give you the excellent resolution needed for defining and identifying ground targets.
INDICATOR PUSHBUTTON CONTROL FUNCTIONS: RANGE - Instant pushbutton selection of six ranges 10/25/50/100/200/300. TILT - 12°, for the full weather picture. AZ MK - Activates display of azimuth strobe lines at 30° intervals. STAB - On/off function control for stabilization. TGT ALRT - Activates circuitry to automatically alert the pilot when any level three (red) target appears in a 7%° sector either side of the nose, at ranges between 60to 150 nautical miles, regardless of selected range. IT - Intensity control, controls the display brightness. wx/c - Weather/cyclic control. This alternate action control selects the weather or cyclic modes. In weather, the storm activity is shown in the familiar green/yellow/red color scheme. In cyclic, preset gain is automatically selected and the red "cells" flash on and off twice per second. FRZ - Stops display update while memory continues to update with current information. GAIN - Radar receiver gain is continuously variable with detented preset position.

Sperry/Honeywell PRIMUS 500 Series Color Radar System DI-5001, RT-5001, AP-5001 (Reconditioned System)
$0.00
CALL FOR CURRENT PRICING!
The Honeywell/Sperry Primus 500 color weather radar is a "bullet-proof" system specifically designed for the short to medium-range mission. With extremely high resolution for applications where target discrimination is critical, the Primus 500 radar is perfect for offshore oil operations, coastal patrol, commuter airlines, ice patrol, search and rescue, corporate helicopter, STOL operations, and military operations. With built-in multimode capability, the Primus 500 can operate in the radar-only mode for weather, avoidance/terrain mapping; the beacon-only mode for radar navigation direct to the beacon location; or in the "both" mode for simultaneous radar and beacon operation. The Primus 500 utilizes a gyro stabilized flat plate phased array antenna for the ultimate in range performance without ground clutter. The system range selections start at 2.5 nautical miles and extend to 200 nautical miles. The high-resolution Primus 500 in radar/map mode identifies prominent terrain features and presents them on a crisp, clear, non-fading display. When the weather is down and you've got to go the Primus 500 color radar will get you there safely and comfortably. This 200-mile premium system uses the standard green, yellow and red colors for weather mode operation. Green represents light showers; yellow indicates medium rainfall rates, and red shows heavy precipitation. This color combination along with this system's excellent digital memory results in an easy-to-read and highly accurate display of the weather ahead. Extended Sensitivity Timing engineering means target size variations when you change gain are virtually eliminated. With FTC, close-in range accuracy is maintained, regardless of gain settings. The multimode Primus 500 radar uses a unique indicator color scheme for mapping. Black represents no return while blue; yellow and magenta represent targets with increasing amounts of reflectivity. Range marks and alphanumerics are shown in green. In addition, the 500 ColoRadar indicator can display information from any Sperry Data Nav system. With Data Nav, electronic checklists and navigation map displays are possible, making the Primus 500 system true multifunction radar. Just add a Honeywell/Sperry Data Nav III or IV multifunction display system. You can call up checklists or create a complete pictorial display of navigation data and weather on your radar screen. Data Nav systems are compatible with most GPS, INS, and DME based RNAV systems. The Primus 500 is one of the best radars for precision terrain mapping. With a full 10,000 watts of transmitter power, the Sperry/Honeywell 500 Color Radar system uses multiple pulsewidths for maximum resolution on all ranges. A 2.35 microsecond pulsewidth is used for long range mapping performance, while the extremely short 0.6 microsecond pulsewidth is used for very high resolution, close-in mapping. For short-range performance, the Primus 500 radar will track a target all the way down to 500 yards in front of the aircraft. As a further short-range enhancement, Fast Time Constant (FTC) eliminates all but the leading edge of the target. "STC" circuitry calibrates the weather targets at more than twice the range of competitive systems without extended STC. That's a real performance-plus for the Primus 500 radar. The pilot-selectable target alert automatically warns of "red" targets in a 15° arc, 60 to 160 miles directly in front of the aircraft even if shorter ranges are selected. An unmistakable "TGT" (target) warning is flashed on the screen if a red target appears in the monitored area. The Honeywell/Sperry Primus 500 radar has the built-in capability to interrogate, receive, process and display transponder beacons, both in the traditional format and the RTCA DO-172 ARA format. In beacon-only mode, the indicator shows beacon targets only; no primary radar targets are displayed. This clear, uncluttered picture permits radar navigation directly to the beacon location. The "both" mode operation of the Primus 500 system presents the pilot with a primary radar display that is integrated with beacon target overlays. When the both/weather mode is selected, you can analyze the weather patterns at the beacon location. In the both/map mode, the terrain surrounding the beacon can be studied. Always presented in a contrasting color, 172 beacons are presented in white. If the code of the DO-172 beacon matches the code selected by the pilot via the beacon select switch, the matched beacon is highlighted by changing its color. Beacon targets are clearly visible, even when co-located with a primary radar target. Traditional beacons and non-matching DO-172 beacons blink white and blue in the both/weather mode, and white and green in the both map mode. Matching DO-172 beacons are a steady blue or green in the both/weather or both/map modes respectively. A separate beacon receiver gain control is used to lower the receiver gain for close-in operation with high power beacons. The normal antenna scan angle is 120°, but at the press of a button, the pilot can select a 60° scan to double the displayed data update rate. Electronic azimuth marks at 30° intervals are available at the touch of a switch and, a receiver gain control allows precise adjustment for low altitude mapping.
INDICATOR PUSHBUTTON CONTROL FUNCTIONS: TGT ALRT - Target alert enables special monitoring circuitry that warns the pilot of "red" targets in a 15° arc between 60 and 160 miles ahead of the aircraft by flashing the "TGT"' warning on the screen. FRZ - Freeze stops the updating of the picture. BCN SEL - Beacon select to choose one of the 15 beacon codes for highlighting on the display. RANGE - Range select switch to set display maximum range and test mode. STAB - Gyro stabilization On/Off switch. STAB OFF - Gyro stabilization "Off" annunciator light. RAD GAIN - Radar receiver gain control with detented preset gain position. "menu" displays; all mode and range selections are direct. With continuously adjustable gain, tilt and intensity controls, you can "tune" the system to your exact requirements. Ease of operation is a cornerstone of Sperry's Primus 500 weather radar. SEC SCAN - Selects 120° or 60° scan. FTC - Selects Fast Time Constant (FTC) in map mode. AZ MKR - Selects electronic azimuth lines at 30° intervals. TIL T - Antenna tilt control can select from 15° down to 15° up tilt. INT - Intensity control adjusts picture brightness. BCN GAIN - Beacon receiver gain control. MODE SWITCHES - Select Off, Standby, Weather, Cyclic or Map modes. RAD/BOTH/BCN - Function switch selects radar only, beacon only or both radar and beacon operation.
