Transponders have become a modern necessity for all aircraft flying in today's airspace environment. Choosing the right one is much more than a matter of price. Some models will not fit shallow stacks. Some models don't meet current FAA requirements and are illegal to use. Still others are prone to design problems that cause maintenance headaches for their owners. Some transponders are 14 volt systems that require voltage changeover kits for 28 volt aircraft. The latest models use all "Solid State" Transmitter output sections which enhances the life of a transponder. Other models feature Mode S with Traffic Information Systems "TIS" capability that receives ATC Traffic information and can show it on many Multi Function Displays.

We strongly suggest you consider buying an altitude encoder with your transponder to comply with FAA regulations regarding flying within 60 miles of Class B airspace. Be sure to look over our encoders when you decide it is time to upgrade.

At APG-Eastern Avionics, our specially trained, all pilot staff can help sort out the options and recommend the transponder that is perfect for your requirements.

Bendix/King KT-73 Mode S Transponder (Exchange for KT-76A) $5,040.00 $4,549.00 On Sale! 066-01164-0101 The Bendix/King KT 73 Data Link Transponder is an affordable solid state, compact general aviation transponder with Mode S capability. Designed for new or retrofit installations, it fits the same mounting rack as the KT 76C and KT 70/71 transponders. Simple-to-operate rotary knobs allow for easy squawk code entry or changes to your aircraft's Flight Identification code. This new capability meets the European mandate for most piston aircraft and is fully upgradeable to 1090 ADS-B, should ADS-B ever become a reality. The KT 73 incorporates all of the key benefits of Mode S technology, providing a direct link between your aircraft and the ground. Mode S gives your aircraft a unique address code for improved aircraft surveillance and reporting accuracy with less pilot workload. The KT-73 also has the ability to send and receive data link information, a major benefit soon to be realized with the advent of ‘Free Flight’, the air traffic system which offers the freedom to select your own path and speed in real time The KT 73 can interface to the KMD 550 or 850 Multi-Function Display to display traffic information. The FAA (US only) is currently operating Mode S secondary surveillance radars that send traffic information, including warning messages, to the KT 73 and are displayed on the KMD 550 or 850. Traffic is shown in three levels out to 7.5 nm and 3000 feet above and below and will be available in nearly all major population areas across the United States. This new system, called Traffic Information Services (TIS), is available at no charge with the proper equipment. The KT 73 has an easy-to-read gas-discharge display that shows encoded altitude and assigned code information simultaneously. Pushbutton selection of VFR code and Remote-Ident switching reduces pilot workload. Built-In Test Equipment (BITE) provides continuous self-test capability. In addition, the KT 73’s surface mount technology construction provides outstanding reliability. The KT 73 is TSO’d as a C112 Class 3A transponder and is suitable for use at up to 50,000 feet. THE PRICES SHOWN ABOVE REFLECT A WORKING KT-76A AS A TRADE-IN Hot Tip! This transponder is BIG NEWS for the US market! If you are flying near any major ATC center in the US this transponder will receive ATC traffic data (TIS) and display it on your KMD-250,KMD-550 or KMD-850 MFD! With enhanced safety, operating efficiency and information exchange capability the KT 73 is as good as it gets in a transponder.

Garmin GDL-90 ADS-B $9,999.00 013-00176-01 The Garmin GDL-90 is general aviation's first certified ADS-B Universal Access Transceiver (UAT). The TSO C145a remote-mount unit, is certified to support a broad array of Automatic Dependent Surveillance-Broadcast (ADS-B) broadband services. It is designed to interface with the Garmin MX20 multi-function display and includes a TSO-C145a WAAS GPS sensor that offers outstanding position accuracy and integrity. The GDL 90 uses ADS-B technology — a new technology that allows pilots in the cockpit and air traffic controllers on the ground to "see" aircraft traffic with much more precision than has ever been possible before. ADS-B makes flying safer and provides for more efficient use of our airspace. It is the technology behind the FAA's air traffic management concept known as "Free Flight." The Garmin GDL 90 is designed to transmit, receive and decode ADS-B messages via a digital datalink. It broadcasts your aircraft's position, velocity, projected track, altitude, and flight identification to other equipped aircraft in your vicinity, as well as to ground-based transceivers maintained by the FAA. The broadband datalink itself operates on 978 MHz. It is capable of data transmission rates in excess of 1 megabit per second, providing the band width to transfer large graphical weather files, TFRs, and traffic in real time. The GDL 90 relies on the infrastructure that is part of the FAA's Safe Flight 21 program. This program is currently under development with implementation of the ground-based portion of the ADS-B network taking place along the East Coast and in Arizona. Additional installations of ADS-B ground stations are planned for Alaska and the Gulf of Mexico, with the rest of the U.S. to follow. The ground stations can track aircraft movement and will eventually be used to broadcast traffic and weather services. Pilots equipped with the GDL 90 and operating within the ground station coverage area will receive TIS-B traffic, FIS-B weather, and TRF services free of charge. There are no monthly fees or usage charges. Our Special Sale Price Includes base CERTIFICATION and INSTALLATION in most aircraft at our Punta Gorda facilities.
