  2. Estimated time of arrival - Wikipedia

    en.wikipedia.org/wiki/Estimated_Time_of_Arrival

    Accurate and timely estimations of times of arrival are important in several application areas: In air traffic control arrival sequencing and scheduling, where scheduling aircraft arrival according to the first-come-first-served order of ETA at the runway minimizes delays. [4] [5] In airport gate assignment methods, to optimize gate utilization ...

  3. Direction of arrival - Wikipedia

    en.wikipedia.org/wiki/Direction_of_arrival

    Various techniques for calculating the direction of arrival, such as angle of arrival (AoA), time difference of arrival (TDOA), frequency difference of arrival , or other similar associated techniques. Limitations on the accuracy of estimation of direction of arrival signals in digital antenna arrays are associated with jitter ADC and DAC. [3]

  4. Onboard passenger information system - Wikipedia

    en.wikipedia.org/wiki/Onboard_passenger...

    ITS/ITCS – the PIS systems often interface with ITS systems to retrieve real-time information regarding the current service (e.g., estimated arrival/departure times), connecting services (e.g., departure times/platforms of multi-modal services in the next station), service alerts (e.g., announcements regarding current and/or future disruptions).

  5. Time of arrival - Wikipedia

    en.wikipedia.org/wiki/Time_of_arrival

    The peak at time = 5 is a measure of the time shift between the recorded waveforms, which is also the value needed for equation 3. Figure 4b shows the same type of simulation for a wide-band waveform from the emitter. The time shift is 5 time units because the geometry and wave speed is the same as the Figure 4a example.

  6. Flight plan - Wikipedia

    en.wikipedia.org/wiki/Flight_plan

    Estimated Time Enroute: Planned elapsed time between departure and arrival at the destination. Remarks: Any information the PIC believes is necessary to be provided to ATC. One common remark is "SSNO", which means the PIC is unable or unwilling to accept a SID or STAR on an IFR flight. Fuel on Board: The amount of fuel on board the aircraft, in ...

    en.wikipedia.org/wiki/Porkchop_plot

    The green lines represent the Sun-Earth-Probe angle upon departure. [clarification needed] In orbital mechanics, a porkchop plot (also pork-chop plot) is a chart that shows level curves of equal characteristic energy (C 3) against combinations of launch date and arrival date for a particular interplanetary flight.

  9. On-time performance - Wikipedia

    en.wikipedia.org/wiki/On-time_performance

    To calculate the percentage of vehicles on time, comparison is needed with the timetable. A comparison is often completed for arrival time rather than departure time, but both are common. Departure times are normally more on-time than arrival times, as incidents and breakdowns occur that reduce the on time performance.
