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 ...
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]
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).
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.
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 ...
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.

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.
