True or False: The temperature control switch on the ECS panel controls the temperature of both heating and defogging air.

The temperature control switch on the ECS (Environmental Control System) panel indeed controls the temperature of both heating and defogging air, making the statement true. This switch is integral to the overall operation of the ECS, allowing the pilot to regulate the cabin temperature as well as the airflow directed to the defogging system. When the heating is adjusted, it affects the temperature of the air for both heating the cabin and for defogging the windshield, enhancing visibility and comfort during flight.

The absence of functionality for just heating or just defogging in the options supports the conclusion that the switch has a dual role. Therefore, it is accurate to say that the temperature control switch influences both aspects of air temperature regulation in the T-6 aircraft.
