AIR CONDITIONING GROUND CONNECTION
An external conditioned air-source can be connected to the airplane to
supply hot or cold air directly into the cabin.
The operation consists of connecting the source and starting supply to
the aircraft. Supplied air pressure must not exceed 127 mm H
2
O (5 in
H
2
O), maximum air temperature must not exceed 71
o
C (160
o
F) and
maximum flow must not exceed 3,6 m
3
/min (127 ft
3
/min, 96 lbm/min).
The source must be capable of supplying 50040 BTU/h.
The use of external conditioned air does not require any setting of the
aircraft systems since the external conditioned air goes directly to the
distribution ducts. However, it is recommended that the main door be
left open when external air is being used, to prevent inadequate
external source operation and to avoid cabin bump.
