Hi friends,
Presently none of the programms like the Microsoft F.S.X or FS 2004 have a keyboard key or Joystick button  allotted to toggle the ON/OFF/Reset functions of the cockpit clock. I feel such an allotment will be quite handy while flying the timed manueovers like Holding Patterns, Procedure Turns (Course Reversal) and Circling Approaches as oherwise one has to fumble with the mouse, loosing considerable time to click on the clock buttons. Some of the expert  F.S software programmers may consider this as a genuine need and be able to programme a suitable add-on of this type. I am serious F.S Pilot even though I am only a Base Member and with little knowledge in electronics. I hope you friends appreciate my suggestion. Thanks.
