Definition
A manufacturer-published reference manual that explains how to operate a specific Electronic Flight Instrument System (EFIS), covering its display layout, controls, modes, normal procedures, and limitations for the exact make and model installed in the airplane.
Plain English
The handbook from the company that built the glass cockpit, telling the pilot how that particular system works and how to use it correctly.
Context Anchor
Seen when learning or checking the operation of glass-panel flight instruments in the cockpit.
Derivation
EFIS stands for Electronic Flight Instrument System — the screens that replace traditional round-dial instruments. 'Pilot Guide' simply means a guide written for the pilot, as opposed to a maintenance manual written for technicians.
Why Pilots Care
Correct use of the EFIS depends on knowing exactly how that aircraft's system presents data so the pilot does not misread critical flight information.
Intuition Check
Do not treat an EFIS Pilot Guide as general flying advice. It is specific guidance for operating a particular electronic flight instrument system.
Example Sentence 1
Before her first flight in the new airplane, she spent the evening reading the EFIS Pilot Guide to learn how the display modes and autopilot interface worked.
Example Sentence 2
Before the checkride the pilot reviewed the EFIS Pilot Guide to confirm the meaning of each color-coded alert on the primary flight display.
