The purpose of this post is to outline the reasoning why an expert ATC controller would include flow control in the ATIS remarks.
Flow control is a traffic flow management technique used in order to regulate the rate at which aircraft enter congested resources such as airport airspace to a level no greater than the resource can accept. It can be added in the ATIS remarks for any period of time at any time.
Aircraft will be delayed at their departure airport in order to manage demand and capacity at their arrival airport, if the airports’ demand exceeds capacity for a sustained period. Flights will be delayed primarily at the gate, which in turn regulates their arrival time at the impacted airport.
Controllers will primarily use reminders in-app for each aircraft to keep track of the specific aircraft’s delay dependent on when they spawn at the gate.
Flow control is not to be to be confused for a gate hold, as a gate hold is not known as a traffic flow management technique because you are simply holding all traffic at the gate and not allowing any aircraft to push back.
An example of when flow control could be used is during a flash flight, to mitigate the bottlenecks that type of traffic would create at the destination airport.
As a pilot, keep in mind the following, which applies to Infinite Flight:
FAR 91.103 – Preflght action
Each pilot in command shall, before beginning a flight, become familiar with all available information concerning that flight. This information must include—
(a) For a flight under IFR or a flight not in the vicinity of an airport, weather reports and forecasts, fuel requirements, alternatives available if the planned flight cannot be completed, and any known traffic delays of which the pilot in command has been advised by ATC;
So when you hear flow control in ATIS, expect delays and be patient.
The touchdown zone markings identify the touchdown zone for landing operations and are coded to provide distance information in 500 feet (150m) increments. These markings consist of groups of one, two, and three rectangular bars symmetrically arranged in pairs about the runway centerline. For runways having touchdown zone markings on both ends, those pairs of markings which extend to within 900 feet (270m) of the midpoint between the thresholds are eliminated.
Runway threshold markings come in two configurations. They either consist of eight longitudinal stripes of uniform dimensions disposed symmetrically about the runway centerline, or the number of stripes is related to the runway width as indicated. A threshold marking helps identify the beginning of the runway that is available for landing. In some instances the landing threshold may be relocated or displaced.
Visual runways are used at small airstrips and are usually just a strip of grass, gravel, ice, asphalt, or concrete. Although there are usually no markings on a visual runway, they may have threshold markings, designators, and centerlines. Additionally, in the real world, they do not provide an instrument-based landing procedure; pilots must be able to see the runway to use it.
There are runway markings and signs on most large runways. Larger runways have a distance remaining sign (black box with white numbers). This sign uses a single number to indicate the remaining distance of the runway in thousands of feet. For example, a 7 will indicate 7,000 ft (2,134 m) remaining. The runway threshold is marked by a line of green lights.
