CAT A switch
The CAT A switch allows the pilot to select what CAT A departure they require. When selecting the required profile it displays target bugs/beam bars etc on the PFD which the pilot then fly's the aircraft attitude to meet the targets. For example on the AI when the CAT A switch is selected for a back up profile it will display a horizontal bar above the horizon at the desired attitude to complete the procedure properly. At TDP the bar will then change to show below the horizon, again the pilot then follows the command and selects nose down to the bar and at Vtoss the bar moves again to 5 degrees above the horizon.
One big computer game really.
One problem I feel is that it requires the pilot's head to be in the instruments for the whole takeoff procedure.
