What is the path for condensate water from the conditioned air in the air conditioning packs?

• A. It is discharged overboard via drain.
• B. It drains into lavatory system.
• C. It is ducted back into ram air flow to cool heat exchangers.
• D. It is stored in condensate tank.

Answer: (C)

The water that condenses from the cooled, conditioned air is captured and routed into the ram air path rather than being sent to lavatories or kept in a tank. By directing the condensate into the ram air stream, it participates in cooling the heat exchangers through evaporative-like cooling as it mixes with the ram air and exits the system. This keeps water out of the pack interior and eliminates the need for separate drain lines or storage tanks in this design.
