Abstract
A method for determining the “Out,” “Off,”. “On,” and “In” (OOOI) times for an aircraft, based on parametric data sampled in the aircraft. “Out” means out of the gate, “Off” means off the ground, “On” means on the ground, and “In” means in at the gate. Greenwich Mean Time (GMT), brake pressure, magnetic heading, ground speed, flight number and flight leg, engine start/stop, and air/ground switch are currently available parameters that can be sampled and presented to determine the OOOI times for a given flight and this data downloaded.
Claims25
A system of providing a retrievable record of the “Out,” “Off,” “On,” and “In” (OOOI) times of an aircraft comprising:
- a plurality of sensors located throughout the aircraft for sensing routine aircraft conditions and generating parametric data;
- a central processing unit positioned within the aircraft for receiving the parametric data and calculating the OOOI times of the aircraft;
- a data store positioned within the aircraft and connected to the central processing unit and operative to accumulate and store the data relating to the calculated OOOI times of the aircraft;
- and
- a wideband spread spectrum transceiver coupled to the data store and operative to download the data relating to the calculated OOOI times of the aircraft over a wideband spread spectrum communication signal.
A method of providing a retrievable record of the “Out,” “Off,” “On,” and “In” (OOOI) times an aircraft comprising the steps of:
- acquiring parametric data relating to the OOOI times of an aircraft during taxi, takeoff, flight and landing of the aircraft;
- accumulating and storing within a data store of a ground data link unit the data relating to the OOOI times;
- and
- downloading the data relating to the OOOI times that has been accumulated and stored within the data store over a wideband spread spectrum communication signal.
A method of providing “Out,” “Off,” “On,” and “In” (OOOI) times of an aircraft comprising the steps of:
- sampling parametric data that is routinely sampled and presented as a stream of data to a flight data recorder of an aircraft;
- calculating within a central processing unit positioned within the aircraft the OOOI times of the aircraft from the parametric data;
- storing data relating to the calculated OOOI times of the aircraft within a data store positioned within the aircraft;
- and
- downloading the data relating to the calculated OOOI times over a radio frequency communication signal to an airport based receiver.
