Abstract
A transponder having a subsystem for providing an altitude alert function signifying a deviation from a set altitude is described. The subsystem includes an input for receiving an altitude deviation limit associated with the set altitude, a CPU receiving updated altitude and determining a difference between the updated altitude and the set altitude associated with the altitude deviation limit, and a transponder subsystem output device for providing the difference between the updated altitude and the set altitude to a user.
Claims18
A method for providing a density altitude function in a transponder, the transponder receiving updated altitude and transmitting the updated attitude, the transponder having a user interface configured to display a density altitude page, said method comprising:
- receiving data relating to at least one of static air temperature and pressure altitude, total air temperature, indicated airspeed, and pressure altitude;
- calculating an outside air temperature based on the received data;
- calculating the density altitude based on the received data;
- and
- displaying the outside air temperature and the density altitude on the user interface.
A transponder configured to transmit an altitude and provide an altitude alert function, said transponder comprising:
- an input receiving updated altitude;
- an output transmitting the updated altitude;
- inputs receiving data relating to at least one of static air temperature and pressure altitude, total air temperature, indicated airspeed, and pressure altitude;
- a processor unit calculating an outside air temperature based on the received data and calculating the density altitude based on the received data;
- and
- a user interface displaying the outside air temperature and the density altitude.
