The sensitivity of runway occupancy time (ROT) to various operational factors associated with the operation of a research high-speed Rollout and Turnoff (ROTO) system has been investigated using a 3 degree of freedom (yaw, forward, lateral) non real-time aircraft Size: 6MB.

The following operational factors were studied and are listed in the order of decreasing ROT sensitivity: ice/flood runway surface condition, exit entrance ground speed, number of exits, high-speed exit locations and spacing, aircraft type, touchdown ground speed standard deviation, reverse thrust and braking method, accurate exit prediction capability, maximum reverse thrust availability, spiral-arc vs.

circle-arc exit geometry, dry/slush Author: S. Goldthorpe. Runway Occupancy Time as Element of Runway Capacity. A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text.

Average runway occupancy time will be calculated for each runway threshold; due to the fact that each runway has its own configuration. This leads to different average time of runway occupancy in each threshold.

After taking the runway occupancy time, the arithmetic average of the runway occupancy time (MATOP) is calculated separatelly by aircraft category, as follows. Runway occupancy time (ROT) data is essential to effectively 12 monitor current airport operating efficiencies and to plan for the introduction of new aircraft 13 surface movement guidance and control systems.

A fast and accurate algorithm to calculate 14 ROT using surface track data is described. runway occupancy time: Status Mandatory for Contexts SESAR.

Note Lexicon Release. Lexicon Release Runway occupancy time (ROT) is just what it sounds like: the amount of time that a runway is occupied or not usable by another aircraft.

For arrivals, this is generally measured from the time the aircraft touches down until the time the aircraft is clear of the runway. Runway occupancy time during landing will vary depending on the location of exits, wind and runway surface conditions. However, by making sound, informed decisions, pilots can contribute to reducing wasted runway capacity.

Consistent and predictable runway occupancy times also assist controllers deliver optimum separation. During peak periods,File Size: 2MB. runway-occupancy time The time taken by an arriving aircraft from the time it crosses the threshold until it turns off the runway, or the time taken by a departing aircraft from the moment it takes an active runway until it clears the departure end.

Minimising departure runway occupancy times can be helped by: ƒ completing checklists in due time to minimise checks on the runway ƒ lining-up without delay and avoiding backtracking unless required for performance reasons ƒ reacting promptly to take-off clearance ƒ most importantly - don’t rush and be Size: 2MB.

The comparison of landing time intervals and runway occupancy illustrates that wake vortex separation requirements limit runway capacity when heavy or Boeing is the lead aircraft.

Lastly, this study evaluates the runway capacity benefits of reduced wake separation requirements for the aircraft re-categorization (RECAT) by: 6.

thrust reversers usage and runway occupancy time. For a detailed description of the BTV, please refer to the July issue of the Airbus FAST magazine. Airbus decided to use the BTV as the basis for the development of safety functions intended for the prevention of runway excursions The ROPS was born.

From BTV to ROPS. Departure Runway Occupancy Time. Good evening, I have been trying to get some guidance material for DROT at busy airports. I am specifically looking at reference times to use for line-up from CAT II and CAT I holding points, flight crew reaction time to take-off clearances and take-off times.

I realise there probably isn't a hard and fast rule. proESTOP - Runway Occupancy Time Estimator. proESTOP – Runway Occupancy Time Estimator_WAC Carlos Barbas. 11/03/ 5. INFLUENCE OF ROT ON AIRPORT CAPACITY. Actual need to estimate occupancy timesFile Size: 1MB. Precision Approach Path Indicator (PAPI).

The precision approach path indicator (PAPI) uses light units similar to the VASI but are installed in a single row of either two or four light units. These lights are visible from about 5 miles during the day and up to 20 miles at night.

The visual glide path of the PAPI typically provides safe. The results of this model concluded that the optimum location of runway turnoffs is quite sensitive to aircraft population, number of exits, and exit speeds. The same model used external atmo- spheric corrections to modify the baseline results due to.
