26
Ground Air Conditioning
Low Pressure Ground Unit
(Limitations)
- Do not use conditioned air simultaneously from PACK and LP ground unit (to avoid chattering of non-return valves).
- Airflow supplied by the ground cart shall not exceed 2.6 lbs/s.
27
Ground Air Conditioning
High Pressure Ground Unit
(Limitations)
- Do not use HP ground unit when the APU is supplying bleed air to avoid bleed system damage.
- An HP ground unit may be used for air conditioning provided the air supply is confirmed to be free from oil contamination.
