Abstract: A transponder system that is adapted to be positioned in an aircraft includes a transponder that is adapted to transmit information pertaining to the aircraft in which the transponder is positioned includes at least one receiver that is adapted to receive information including information pertaining to another aircraft. The receiver(s) is adapted to receive different types of data on multiple different frequencies. A display, which may be integral with the system housing or remotely mounted, is adapted to display (i) information received by said receiver and/or (ii) information to guide user input selection of information transmitted by said transponder. The housing houses the transponder, the receiver and, in one embodiment, the display. The existing transponder in the aircraft can be removed thereby leaving an opening in the aircraft and the transponder installed in the opening.

Abstract: An Automatic Dependent Surveillance-Broadcast (ADS-B) system, and method of harmonizing a transponder Squawk code and an ADS-B system, ensures that a Squawk code broadcast by the ADS-B system matches the transponder Squawk code. The transponder Squawk code is transmitted from a transponder positioned onboard an aircraft, and the transmitted transponder Squawk code is received by a device positioned onboard the aircraft in which the transponder is installed. The ADS-B system is updated with the received transmitter squawk code. The squawk code is transmitted using the ADS-B system.

Abstract: An Automatic Dependent Surveillance-Broadcast (ADS-B) system, and method of harmonizing a transponder Squawk code and an ADS-B system, ensures that a Squawk code broadcast by the ADS-B system matches the transponder Squawk code. The transponder Squawk code is transmitted from a transponder positioned onboard an aircraft and the transmitted transponder Squawk code with a device positioned onboard the aircraft. A Squawk code input of an ADS-B Squawk code to be transmitted with the ADS-B system is received. The ADS-B Squawk code is compared with the received transmitter Squawk code using a comparator and the pilot is informed whether the transmitter Squawk code matches the ADS-B Squawk code. A message formatter generates a message that includes the ADS-B Squawk code. A wireless transmitter broadcasts the ADS-B Squawk code generated by the message formatter.

Abstract: A system installed in an aircraft automatically retrieves and displays approach minimum data to the pilot, thereby relieving him or her of the burden of searching for the desired information. The display of the data may take the form of a complete or partial image of a published approach chart. In a variation, the system may both automatically retrieve and automatically enter the desired data into the flight plan, thereby relieving the pilot of both the searching and data-entry tasks. The system may include a database, a screen, a control, and a controller.

Abstract: An aircraft stall warning system includes an angle of attack sensor which provides a signal to an angle of attack processor which provides an angle of attack signal to a display. An air pressure sensor provides an air turbulence intensity ratio signal to an aerodynamic performance processor which provides an aerodynamic performance signal to the display. The display therefore simultaneously displays both theoretical stall margin and actual stall margin to thereby provide a pilot with wing contamination information.
