 Additionally the light control is available on the AAP.
 (d) Signal transmission The settings initiated on the FAP are sent directly to the CIDS director, whereas the AAP settings are sent via the respective DEU type B to the CIDS director. The director sends commands via the top lines to the DEUs type A. The DEUs type A control with help of these commands the light intensitiy of the general illumination ballast units.
 (e) Automatic activation With one or more engines running (oil pressure high), the light intensity is dimmed automatically in the FWD entrance area if the cockpit door is open. In case of low cabin-pressure all lights are switched on with full brightness independently from all other light volume settings.

 (c)
 Signal transmission If the reading lights are switched on/off from the PSUs, a signal is sent directly to the PISA or reading light. If the attendant work lights are switched on/off from the attendant work stations, a signal is sent directly to the StA PISA. When the signal is sent to the reading light, the reading light is switched on/off directly. When the PISAs or StA PISAs receive the signal, they switch on/off the reading lights and attendant work lights.
