Question

With the ADC switch in NORM, the pilot and copilot displays receive data from:

a) Standby Attitude Indicator
b) Inertial Reference System (IRS)
c) ADC 1 for the pilot and ADC 2 for the copilot
d) Ground Proximity Warning System (GPWS)

Answer 1

With the ADC switch in NORM, the pilot's displays receive data from ADC 1 and the copilot's displays receive data from ADC 2 for reliable and redundant flight data.

Step-by-step explanation:

When the ADC (Air Data Computer) switch is in NORM, the pilot and copilot displays receive data from c) ADC 1 for the pilot and ADC 2 for the copilot. These Air Data Computers are dedicated systems that provide critical flight parameters such as airspeed, altitude, vertical speed, and air temperature, among others. Each ADC provides data to its respective set of instruments to ensure redundancy and reliability in the aircraft’s systems. The ADCs are completely separate from the other systems listed, such as the Standby Attitude Indicator, Inertial Reference System (IRS), and Ground Proximity Warning System (GPWS), which serve different purposes in the aircraft’s avionics.
