The air conditioning system operates when which components are active?

The air conditioning system in the aircraft requires specific conditions to function properly, and one of the key requirements is that the generator must be online. When the generator is operational, it provides the necessary electrical power to run the air conditioning components.

Additionally, the air conditioning system will activate when the A/C switch and/or the DEFOG switch is turned ON. This means that as long as one of these switches is engaged, the air conditioning system can operate. The DEFOG switch specifically helps to clear the moisture from the aircraft's windscreen and may require the A/C system to function for optimal performance.

Thus, the correct answer encompasses both the requirement of the generator being online and the activation of either the A/C switch or the DEFOG switch, allowing the air conditioning system to work effectively during flight operations.
