PZ-800 Performance Computer
Leading Particulars
Table 9-7
The purpose of the PZ-800 Performance Computer is to provide the pilot
with detailed performance information and automatic control of the
throttles. Previously, detailed performance information
was only
available by spending a great deal of time in the aircraft performance
manuals. With the performance functions of the PZ-800, the pilot now has
access to a computerized performance manual. The pilot is supplied with
flight-planning information prior to takeoff such as fuel and time
required. In flight, the
system
provides the pilot with real-time
information based on current aircraft and atmospheric conditions. In
case of changes to the flight
plan, the pilot can be updated immediately
on the consequences of the changes. This capability extends the pilots
ability to conduct the flight safely and economically.
The performance system is enhanced by the autothrottle. Aircraft
parameters calculated by the performance functions can be coupled to the
autothrottle and flight guidance computer for effortless tracking of
these commands. Alternatively, the autothrottles can be set to maintain
pilot-entered values. In addition to the PZ-800 Performance Computer,
the autothrottle function requires one SM-81O Autothrottle Servo-Clutch
Assembly for each engine controlled. Inputs from the throttles, engines,
flight guidance controller, and display controller are also required.
The PZ-800 Performance Computer digital outputs transmitted over the ASCB
are listed in Table 9-8.
