Holding patterns are a fundamental aspect of virtual and real-world aviation used to manage traffic flow and ensure safe separation in high-traffic conditions or unexpected delays. On the VATSIM platform, holds are sometimes used by controllers to space arrivals, manage congestion, or coordinate spacing into busy airports—especially around events or peak hours.

A hold typically means flying a racetrack-shaped circle at an already selected fix, with specified inbound and outbound legs, turn direction, and timing. They are given by air traffic controllers and must be followed to the letter to ensure safe and orderly traffic flow. Hold can also be taken voluntarily by pilots, for example, to investigate a malfunction or to wait for clearance into controlled airspace.

When being given a hold on VATSIM, pilots must acknowledge the instruction clearly and accurately, then perform the hold according to proper procedures. Most modern aircraft, particularly airliners with advanced avionics, are capable of performing holds automatically through their flight management system (FMS). Nevertheless, it is still valuable to know manual basics of holding procedures—i.e., entry types (direct, parallel, teardrop) and timing corrections—particularly in less automated aircraft.

VATSIM controllers endeavor to provide realistic and equitable holding instructions, usually mimicking real-life procedures in accordance with STARs (Standard Terminal Arrival Routes) and local customs. Pilots are expected to study charts for published holding points and be willing to comply with unpublished holding instructions where appropriate.

And as always, professionalism and communication are the bottom line. Pilots must read back hold clearances accurately and remain situationally aware while in the pattern. Misunderstanding or failure to properly execute a hold can impact traffic in the area and slow the advance of arrivals.

Holding procedures on VATSIM offer the chance to rehearse true procedures and increase pilot proficiency and situational awareness. By responding professionally and calmly to holding orders, members increase the realism and authenticity of the virtual flight environment.

Hold instructions are common throughout the network, but controllers have several ways of handling congestion with in-air traffic like speed reduction, holding, vectors, and reroutes. Pilots should always be ready to accommodate any instruction given by ATC. Specific instructions given might differ based on local prerogative, standard operating procedure, controller prerogative, or specific needs at hand.
