Method for customizing software functionality with a configuration file
A method of generating data outputs as instructed by a configuration file on a computer system for an aircraft includes processing, as instructed by one or more parameters of the configuration file, data from a first data source. In some embodiments, the first data source comprises either a sensor associated with the aircraft or an addressable memory. In some embodiments, the one or more parameters comprise instructions for using one or more certified functions. The method also includes outputting the processed data to at least one of the addressable memory, a display, and an external device.

processing, as instructed by a parameter of the configuration file, data from a first data source, wherein the first data source comprises either a sensor associated with the aircraft or an addressable memory, and wherein the parameter comprises an instruction to manipulate the data via a certified function to create a new parameter based, at least in part, on the data from the first data source;
performing, as instructed by one or more of the parameter or the new parameter, a validity analysis to create validity data;
formatting, as instructed by the one or more of the parameter or the new parameter, the validity data; and
displaying, responsive to a determination of a valid condition of the validity data, information on a display.

6. The method of claim 2 , wherein, as a part of the processing, the messages from the first data source are formatted as one of a binary coded decimal, a binary numeric representation, and a discrete data word.
7. The method of claim 1 , further comprising passing parameters from the configuration file to the functions during an initialization process at a startup of a system operable to carry out the method.
8. The method of claim 1 , further comprising adding new parameters in the configuration file that define new data outputs, wherein the adding occurs after the one or more certified functions have been certified.
9. The method of claim 1 , wherein the certified function comprises one or more of the following functions: addition, define a constant, difference, division, multiplication, subtraction, arccosine, arc sine, arc tangent, arc tangent 2, ceiling, cosine, sine, exponent, absolute value, floor, fmod, log, log 10, log 2, maximum, minimum, power, square root, normalize, switch, timer count down, time count up, equal, average, data acquisition, and drawing.
10. The method of claim 1 , wherein the parameter comprises instructions for generating symbology elements.
11. The method of claim 10 , wherein the symbology elements include one or more of the following: a dual pointer indicator, a round indicator, an arc indicator, a line element, an arc element, a circle element, a polygon element, a text element, a group box, a CAS display box element, a tape with top readout element, a tape with bottom readout element, a tape with no readout element, a single pointer element, a dual pointer element, a concentric pointer element, a fuel tank element, a digital parameter indication element, a generic pointer with arc element, a generic pointer with linear movement element, a triple tachometer pointer element, a limit indicator bars, a timer element, and a clock element.
12. The method of claim 1 , wherein a second data source comprises a sandbox adapted to permit processing of data from a second sensor associated with the aircraft.
13. The method of claim 1 , wherein the sensor associated with the aircraft comprises one or more of the following sensor types: global positioning sensor (GPS), Air Data Computer (ADC), Attitude Heading Reference System (AHRS), Datalink/Automatic Dependent Surveillance-Broadcast (ADS-B), weather mapping sensor, analog interface, traffic sensor, remote tune radios, video, remote bugs panel, digital autopilot, airframe/engine data, weather radar, mode S transponder, and fuel flow/quantity.
14. An instrumentation system for an aircraft, the instrumentation system comprising:
an information display unit (IDU) comprising:
a central processing unit (CPU) adapted to carry out instructions for the instrumentation system;
an addressable memory, in communication with the CPU, adapted to store data from at least one sensor associated with the aircraft and data generated by the instrumentation system; and
at least one communication port in communication with the at least one sensor associated with the aircraft and the CPU via a communications link;
wherein the instructions comprise computer-readable program code operable to implement a method comprising:
processing, as instructed by a parameter of a configuration file, data from a first data source, wherein the first data source comprises either a sensor associated with the aircraft or an addressable memory, and wherein the parameter comprises an instruction to manipulate the data via a certified function to create a new parameter based, at least in part, on the data from the first data source; and
