Air Conditioning
- With LP ground unit
- With HP ground unit
- With LP ground unit
- Do not use conditioned air simultaneously from packs and LP ground unit (to avoid chattering of the non return valves)
- With HP ground unit
- An external HP source may be used for air conditioning, provided the air supply is confirmed to be free from oil contamination. Do not use HP ground unit when APU supplies bleed air to avoid bleed system damage.
