PILOT'S OPERATING HANDBOOK

7.12 - VACUUM SYSTEM AND INSTRUMENTS

The airplane is fitted with a vacuum system providing the suction necessary to operate the cabin pressurization
and the leading edge deicing.
Vacuum system includes :
- A pressure regulator
- An ejector
- A regulating and relief valve
- A pressure switch
Compressed air necessary for the ejector to create decompressed air is taken from the powerplant. The air flow is
regulated before going into the ejector which creates necessary vacuum by venturi effect.
A relief valve fixed in cabin to frame C2, maintains the vacuum for pressurization system. In case of pressure drop,
a pressure switch, installed in the system, indicates the failure by causing the
message to light on.

ELECTRONIC STANDBY INDICATOR (ESI-2000)

The L-3 Communications Avionics Systems ESI-2000 Electronic Standby Instrument System consists of an
AMLCD display. An air data sensor is integral to the ESI-2000 housing. A replaceable battery assembly provides
back up power. The Electronic Standby Indicator displays attitude (pitch and roll), along with altitude and airspeed.
The ESI-2000 is powered from the "ESSENTIAL BUS 2", or internal battery ensuring that the airplane can continue
safe flight and landing in the event of a loss of primary attitude and air data displays. Pitot and static pressures are
provided to the ESI-2000 using the airplane pitot probe and static sources.
