Delay

A Delay procedure is used to hold the aircraft at the end of its previous procedure for a specific duration. The aircraft will fly one or more circular holding patterns; the specified cruise airspeed will be held constant during the delay, and the radius of the holding pattern will be adjusted as needed to complete the duration. The site must be an End of Previous Procedure.

Parameter	Description
Turn Mode	Select the turn direction of the procedure; if the mode is set to Auto, STK's Aviator capability will determine the turn direction.
Turn Factor	The Turn Factor is the maximum amount - expressed as a multiplier - that the turn radius will be increased to minimize the bank angle required to complete the turn. The factor is applied only to turns that are performed enroute to the procedure's first control point. The full circles that correspond (or are tangent) to the start/stop turns at the extended radius may not intersect if the factor is set high enough. This parameter is a limit and may not actually be achieved due to the requirement to generate an appropriate turn sequence. You can adjust the slider or enter the value manually in the box, with the minimum value being 1 and the maximum value being 10.

Requested Altitude

Parameter	Description
Mode	Select a mode for handling the altitude of the aircraft from the following options: Level Off - a level off maneuver will be used to bring an aircraft to the altitude specified by the cruise performance model, if the aircraft is unable to attain that altitude during the course of that procedure. Default Cruise Alt - the aircraft will attempt to attain the altitude specified by the cruise performance model during the course of the procedure but will not execute a level off maneuver if it is unable to do so; if a level off maneuver is required to reach the specified altitude, then the procedure will be invalidated. Override - override the cruise altitude and specify an altitude for the procedure.
Altitude	Displays the requested altitude of the procedure; this field can only be edited if the Mode is Override. The altitude is constrained by the lowest ceiling value of the active performance models in the current mission phase.

Cruise Airspeed

Cruise Airspeed parameters define the airspeed performance characteristics of the aircraft during enroute segments of the procedure.

Table - Cruise Airspeed Parameters

Parameter	Description
Cruise Airspeed	Select the method for determining the airspeed from the following options: Minimum Airspeed - constant airspeed at the minimum cruising airspeed for the aircraft. Max Endurance Airspeed - variable airspeed that maximizes the length of time that the aircraft can remain in flight. Max Range Airspeed - variable airspeed that maximizes the distance that the aircraft can fly. Max Performance Airspeed – a custom performance airspeed and fuel flow that you can use to model specific flight conditions. Maximum Airspeed - constant airspeed at the maximum cruising airspeed for the aircraft. Other Airspeed - constant, manually defined airspeed.
Airspeed	Displays the cruising airspeed. If the airspeed type is Other Airspeed, enter the desired airspeed value; otherwise, the calculated value will be displayed and cannot be edited. Select a reference from the drop-down menu - true airspeed (TAS True Airspeed: the speed that the aircraft is moving relative to the airmass that it is flying in.), calibrated airspeed (CAS Calibrated Airspeed: the speed reported by the airspeed indicator, corrected for position and instrument error.), equivalent airspeed (EAS Equivalent Airspeed: the airspeed at sea level (International Standard Atmosphere) at which the dynamic pressure is equal to the dynamic pressure at the aircraft's current true airspeed and altitude.), or Mach The ratio of the aircraft's speed and the speed of sound at the aircraft's altitude, with local atmospheric conditions. number.
