  • ADS-B

    Automatic Dependent Surveillance -
    Broadcast (ADS-B)

    Automatic Dependent Surveillance (ADS-B) is widely recognized as a cornerstone technology for monitoring aircraft in the skies and on the ground in the continuing transformation to a Next Generation (“NextGen”) aviation system.

  • Mode S

    Mode S Transponders

    Mode S Elementary Surveillance (ELS) and Mode S Enhanced Surveillance (EHS) transponders provide additional flight parameters to air traffic control thus improving the quality, detection, identification and altitude reporting of aircraft within the airspace.

  • Cockpit Voice Recorders (CVRs)/Flight Data Recorders (FDRs)

    Cockpit Voice Recorders (CVRs)/Flight Data
    Recorders (FDRs)

    A Cockpit Voice Recorder (CVR) records radio transmissions and sounds in the aircraft’s cockpit, such as the pilot’s voices and engine noises while a Flight Data Recorder (FDR) records aircraft parameters such as altitude, airspeed and heading.

  • Traffic Alert and Collision Avoidance System (TCAS)

    Traffic Alert and Collision Avoidance System (TCAS)

    Traffic Alert and Collision Avoidance System (TCAS) is an airborne system that operates independently from the ground-based Air Traffic Control (ATC) system. TCAS was designed to increase cockpit awareness of proximate aircraft and to serve as a “last line of defense” for the prevention of mid-air collisions.

  • Performance-Based Navigation (PBN)

    Performance-Based Navigation (PBN)

    Information related to the use of Area Navigation (RNAV) Standard Instrument Departures (SIDs), RNAV Standard Terminal Arrivals (STARs), and Required Navigation Performance Authorization Required (RNP AR) Approaches.

  • Electronic Flight Bags (EFBs)

    Electronic Flight Bags (EFBs)

    An Electronic Flight Bag (EFB) is an electronic device that allows flight crews to perform a variety of functions that were traditionally accomplished by using paper references.

  • Emergency Locator Transmitters (ELTs)

    Emergency Locator Transmitters (ELTs)

    Emergency Locator Transmitters (ELTs) are emergency beacons carried aboard aircraft to notify search-and-rescue personnel when an aircraft is down. There are several types of ELTS, and most U.S. civil aircraft are required to carry one.

FAA Releases Updated Advisory Circular for RNP Operations
April 1, 2016
Business aviation operators will benefit from revised, extensive guidelines for conducting required navigation performance (RNP) operations, as defined in a new advisory circular (AC) released by the FAA. AC 90-105A provides aircraft eligibility and operational guidance for conducting RNP operations. Learn more about conducting RNP operations.

Alternative RNP AR Compliance Method Saves Money – Free NBAA Webinar Has Details
June 1, 2015
A cost-saving way to achieve required navigation performance authorization required (RNP AR) database validation was detailed during a recent free NBAA webinar, offering operators an avenue for overcoming what has been a significant hurdle to overall RNP AR certification. Jeppesen, which sponsored the webinar, along with Garmin, invested two years in the alternative method of compliance (AMOC), which takes the place of a linear process that requires operators (or approved third parties) to validate an average of 350 parameters per RNP AR approach against its government source data. This AMOC is available to all avionics OEMs, said webinar presenter Andrew Riedel, Jeppesen's manager of corporate technical standards. Read more about RNP AR.

Free NBAA Webinar Offers Tips on Simpler Approach to RNP Compliance
May 12, 2015
An NBAA webinar, set for 1:30 p.m. (EDT) May 27, will discuss an alternate method of compliance for validating required navigation performance authorization required (RNP AR) approach data, which puts this capability within reach of business aircraft operators. “More efficient, economical and automatic than the current burdensome process, RNP AR potentially gives business aircraft operators access to more airports and procedures that provide better minimums and savings of fuel and time,” said Bob Lamond, NBAA’s director of aircraft traffic services and infrastructure. Members must pre-register for this free webinar, which is sponsored by Jeppesen. Learn more about the RNP compliance webinar.
