Abstract: An apparatus comprising a memory and a processor coupled to the memory, wherein the processor is configured to receive holding instructions for an aircraft, wherein the holding instructions comprise a holding fix, a holding direction, and an inbound leg course, obtain an airspeed for the aircraft, obtain a wind speed and a wind direction affecting the aircraft, calculate a holding pattern for the aircraft using the holding instructions, the wind speed, the wind direction, an inbound leg duration, and the airspeed, obtain Federal Aviation Administration (FAA) protected airspace limits associated with the holding fix, and present the holding pattern and the FAA protected airspace limits to a flight crew member on the aircraft.

Abstract: A method of calculating Federal Aviation Administration (FAA) published or FAA Air Traffic Control assigned aeronautical holding patterns, comprising the steps of: defining navigational way points using their latitude and longitude coordinates; displaying the latitude and longitude that define the point for an inbound turn; defining four posts of a holding pattern; and showing the actual holding space dimensions along with the non-protected airspace. The method may be performed by a stand-alone electronic device or an electronic device having other functions. The latitude and longitude that define the point for an inbound turn can be displayed as a bearing, and/or as a distance along a radial. The inbound turning point can be calculated using a global positioning or flight management system. A turn may be commanded using an automatic flight control system or flight director.
