ASPEN PRO 1000 PFD

The Aspen Evolution EFD1000 Pro PFD gives you all the major tools that help professional pilots fly safely and easily in instrument conditions, at a breakthrough price. The Pro has all the same great features as the Pilot PFD—integral ADAHRS, backup battery, emergency GPS, altitude alerter—plus a whole lot more.

The Horizontal Situation Indicator (HSI) integrates a course pointer and course deviation indicator (CDI) onto your slaved compass rose, and adds two bearing pointers that you can set to any VOR or GPS waypoint, for added situational awareness (and making DME arcs a breeze to fly!). Text information about your active waypoint is right in front of you.

Arc mode is ideal for the en-route segment, showing your own ship at the bottom of the screen, your flight plan legs ahead of you, and nearby navaids and airports around you on a moving map. With optional software, you can even overlay datalink weather graphics and traffic on the map.

The Attitude Director Indicator (ADI) shows the same accurate attitude with airspeed and altitude tapes as the Pilot, and adds more. In approach mode, you’ll have lateral and vertical deviation indicators, along with your approach minimums, right there on the ADI for a tight scan during this critical phase of flight. You’ll get an alert when you reach barometric minimums, and a DH annunciator will illuminate at AGL minimums (when connected to a radar altimeter).

The Pro couples to most GA autopilots and flight directors, through its included Analog Converter Unit (ACU). An integral GPS Steering (GPSS) function can drive your autopilot in HDG mode through most GPS flight plan legs and course changes, and even along curved flight paths (like course reversals and holding patterns) when connected to an appropriate WAAS GPS navigator. If your autopilot supports a flight director, but your current attitude indicator doesn’t, the Pro will give you a single-cue flight director that will make your hand flying even easier, more accurate and safer. The Pro delivers all the capabilities a serious instrument pilot needs on his or her primary instruments

GARMIN GNS 530

The GNS 530 represents the single biggest idea in integrated avionics in years. Traditionally, it would take a host of components to provide the capabilities represented in this one sophisticated box. It is a WAAS-upgradeable IFR GPS, Com, VOR, LOC and glide-slope with color moving map all rolled into one. A TSO'd VHF Com offers a choice of 25 kHz or 8.33 kHz spacing for 760- or 3040-channel configuration respectively. A huge Jeppesen database (that can be updated with a front-loading data card) contains all airports, VORs, NDBs, Intersections, FSS, Approach, DPs/STARs and SUA information. The GNS 530 makes practical use of this information with features like intelligent frequency nomination.

The brilliant colors of the GNS 530's 5-inch display make the pilot-critical information easy to read and interpret. Thanks to a high-contrast color display, the information can be easily read from wide viewing angles even in direct sunlight. It's especially true of the 530's basemap. Pilot's will enjoy enhanced situational awareness by seeing their position relative to cities, highways, railroads, rivers, lakes, and coastlines. But even more important, the appropriate use of color separates land data, terminal areas, route, and approach information for easy pilot scanning and reduced pilot workload. Simply put, the GNS 530 incorporates advanced procedure types usually found only in high-end FMS systems.

The GNS 530 has plenty of growth potential, as there are upgrade paths for WAAS compatibility, TAWS, and Terrain awareness. Pilots will enjoy the GNS 530 as an MFD, especially when it is coupled with traffic, lightning detection, and weather interfaces like Ryan TCAD, TIS from the Garmin GTX 330 Mode S transponder, or Goodrich SKYWATCH™, STORMSCOPE® WX 500. For the latest in graphical and textual weather information, the GNS 530 can connect to XM Satellite Radio's XM WX Weather Service via the GDL 69 datalink receiver. With the FDE prediction program, the GNS 530 may be used for oceanic or remote operations.

GARMIN SL40

When panel space is at a premium, the SL40 VHF comm transceiver combines a lot of capability in a surprisingly small package.

High-Performance Space Saver

It’s an all-purpose, high-performance unit packed with innovative features not found on competitive units. In its space-saving 1.3 x 6.25-inch design, the SL40 incorporates such pilot-friendly features as active and standby flip-flop frequency tuning, direct sunlight-readable alphanumeric display, easy access to National Weather Service broadcasts, a two-place intercom, and more.

Two Radios in One

The SL40's frequency-monitoring function gives you the ability to monitor ATIS or the 121.5 emergency frequency without leaving your assigned ATC channel. This allows you to listen to standby frequencies while giving priority to the active channel, meaning you'll never miss a transmission.

With 8 watts of transmit power and only 35-watt DC input, the TSO-certified SL40 is cool and efficient. No external fans or cooling equipment are required. And like the Garmin SL30, the SL40 will operate on 10 to 32-volt inputs without the need or expense of a separate voltage converter. Maximum sophistication in minimum space: that’s the SL40.

SL40 features
• 760 communication channels
• Frequency range: 118 to 136.975 MHz
• Active and standby flip-flop frequencies
• Volume control
• 16-character high-intensity alphanumeric LED display
