There is a specific holding pattern and procedures for fixed winged aircraft.Is there any specific holding pattern for EVTOL ? as they have capability to hold a position and altitude .
Helicopters can be put in "racetrack" style holds just like fixed wing aircraft, COPTER approaches even include them. There is no reason to believe if/when VTOL aircraft become more prevalent this will be any different.
Hovering is inefficient and difficult which can be made even more complicated when in IMC making it not ideal for a holding maneuver which is often issued to either kill time or allow a pilot time to pull up a new plate or get set up for a new approach.
