Primary Engine Displays - Honeywell PRIMUS 1000 Pilot's Manual

Primary Engine Displays

The engine displays shown in figure 5--5, receive their information from
two DAUs. The two DAUs are each dual channel and receive various
aircraft engine and sensor data. One channel is primary, and both
channels process the data in parallel.
The symbol generator (SG) supplying the EICAS display (normally the
NO.1 SG) also supplies display processing logic for some CAS
messages.
The primary engine displays are shown in the left half of the EICAS
display. The display is divided into seven areas:
N fan (FAN)
D
1
Interstage turbine temperature (ITT)
D
N turbine
D
2
Fuel flow (FF) in pounds per hour (PPH) or kilograms per hour (KPH)
D
Fuel quantity (FUEL lbs, or kg L/R)
D
Oil pressure/temperature (OIL PRESS/OIL TEMP)
D
Engine vibration for low pressure (LP) and high pressure (HP).
D
Some engine warning and status messages are also displayed.
N , ITT, OIL PRESS/TEMP, and VIB LP/HP are gauges. N

flow, and fuel quantity are only digital readouts.
The round engine gauges are a fixed arc with moving pointer and digital
current value window located above the pointer rotation point. Each
engine gauge type is labeled. Vertical gauges have a pointer that moves
on a fixed scale. Some vertical gauges also have a digital display.
The following is a list of the parameters shown on the engine display.
