Designed for air-to-air and air-to-ground operations, TACAN+ meets MIL-STD 291C and NATO STANAG-5034. It has been tested to MIL-STD-810G, MIL-STD-704 and MIL-461E, and meets DO-160F helicopter vibration levels. The TACAN+ system features lightning-protected circuitry and is subjected to Highly Accelerated Stress Screening (HASS) and Highly Accelerated Life Testing (HALT) for maximum system reliability.
Flexible controllers and indicators
The L3Harris TACAN+ incorporates a Sine/Cosine bearing output along with a CDI interface per ARINC 547, and low- and high-level flags per ARINC 547 and 579. This bearing information is pilot-selectable, from either the number one (1) or number two (2) tracking channels. The TACAN+ provides an ARINC 568 Digital Range output from either the number one (1) or number two (2) tracking channels for display of range information on remote EFIS or HSI displays.
Air to Air (A-A) mode
TACAN+ uniquely features two automatically enabled Air-Air (A-A) Transmit-Receive modes providing seamless and enhanced tactical capability, multiple mission capability, and overall operational value not found on other TACAN products. If no A-A bearing signal is detected, TACAN+ enters a High Signal Dynamics 20-Meter mode. In this mode, the TACAN+ receiver is configured to accommodate the strongest received A-A signal and still ensure adequate reception of other weaker signal participating aircraft. This mode enables multiple TACAN+ equipped aircraft to track a ‘lead’ aircraft across a wide range of flying scenarios, down to a minimum closest follower distance of 20 meters. Upon detecting an A-A bearing (Beacon) signal, TACAN+ automatically exits the High Signal Dynamics 20-Meter mode, and enters the Beacon Tracking mode. In the Beacon Tracking mode, the receiver is configured for optimal reception and tracking of the Beacon signal source.
