Does a Boeing 737 NG have Air Data Modules for the standby Pitot probe and static pressure port?
Standby instruments provide a critical backup function and are totally independent from the primary air data system. The dedicated standby probes are connected directly to the standby display unit which is capable of converting the pressure inputs into airspeed and altitude. They only require a 28V DC input from the EMER/BATT power bus to operate.
