A function used in Logical Switches that compares selectable source “a” to a second selectable source “b” using ‘exactly equal’ as the comparator.  The function takes the value of TRUE when the two sources are equal and FALSE when they are not equal.  Two fields labeled V1 and V2 follow the function statement to define source “a” and source “b”.  For example if ‘Ail’ is selected from the drop down choice list in the V1 field, and ‘Rud’ is set in the V2 field, the logical switch containing a=x will become “TRUE” when the rudder and aileron sticks are in the same position.  Any other positions will result in the Logical Switch containing this function to be FALSE.

A fourth field in the logical switch line permits a second source to become part of the comparison evaluation using the logical AND conjunction.  Continuing the prior example, if SG↓ is selected in the AND field, then the logical switch becomes TRUE only when the Aileron stick is exactly equal to the Rudder Stick AND physical switch G is in the down position.

A 5th and 6th field in the logical switch line allow a duration and a delay to be imposed on the switch condition .
