 ===== Flight Controls ===== ===== Flight Controls =====
 +
 +==== input_default ====
 +
 +The input_default is used for all non-discrete (floating point) inputs.
 +
 +Typically these are found for light dimmers, trim inputs, etc. which are typically operated with a joystick or with a cockpit dimmer or trim-wheel, etc. but button inputs are also possible with this generic input.
 +
 +The ''Speed'' is how fast the input responds when a button is pressed and held. With a speed of 0.1 it takes 10 seconds to reach the full deflection 1.0.
 +
 +''Positions'' is the number of steps that are available when a button is pressed to increment the value. A single press of the button increases the value of the input_default by ( Range.max - Range.min ) /  ( Positions - 1 ). In the example below that is 0.0025 increment per button press, so rather fine trim adjustments can be made.

 +==== input_cyclic ====
 +
 +The input_cyclic is an input that loops back around to the beginning when it reaches the end of the ''Range''.
 +
 +  * ''Input'' is the message name
 +  * ''InputEnable'' can be used to disable the input, e.g. if the input is digital and electric power is lost
 +  * ''Range'' is the minimum and maximum value of the input
 +  * ''StepSize'' is the increment when a single step is added, e.g. ''0.0174532'' or 1 degree.
 +  * ''Value'' is the initial position
 +
 +<code>            <[input_cyclic][NAV1Course][]
 +                <[string8][Input][Navigation.SelectedCourse1]>
 +                <[string8][InputEnable][1.0]>

 +                <[uint][StepSize][0.0174532]>
 +                <[uint][Value][1.570796]>

 +
 +==== input_pair ====
 +
 +This is the typical frequency input that can be found in all kinds of aircraft. The frequency input has two values at the same time, an active and a standby value. The standby value is adjustable and can be set without having an immediate impact. Then the frequency is transferred (swapped) to the active frequency and the previously active frequency is now the standby frequency.
 +
 +  * ''Input'' is the message name for the standby value
 +  * ''InputSwap'' is the transfer button message
 +  * ''InputEnable'' can disable the input, e.g. when electrical power is not available
 +  * ''Range'' is the minimum and maximum value for both values
 +  * ''Positions'' is the number of increments within the Range. When the step increment is known (e.g. 50 kHz) and the limits of the Range are known (e.g. 108 MHz to 118 MHz) the Positions is just: ( Range.max - Range.min ) / step + 1, e.g. ( 118000000.0 - 108000000.0 ) / 50000.0 + 1 = 200 + 1 = 201.
 +  * ''StepLarge'' is the number of small steps that make a coarse step. E.g. 20 x 50 kHz = 1 MHz or 40 x 25 kHz = 1 MHz
 +  * ''Active'' and ''Standby'' are the initial two values
 +
 +For optional automatic frequency tuning (autotuning):
 +  * ''InputExternal'' is an autotuning input from the ''flight_management'' or ''autotuning'' class.
 +  * ''Manual'' is the initial condition weather or not autotuning is on (1.0 if manual control)
