2. Different characteristics: The enhanced near-ground early warning system uses its own global airport location database and terrain database, and uses information such as aircraft position, barometric altitude and flight trajectory to judge potential collision risks. GPWS is mainly composed of near-ground warning computer, warning light and control panel. The near-ground warning computer is the core, and the limit data of various warning modes are stored in the computer, which is compared with the actual state data of aircraft transmitted by other systems.
3. Different functions: EGPWS uses terrain database, so EGPWS can send out early warning signals earlier than GPWS. In EGPWS, the computer keeps searching the database along the scheduled flight path of the aircraft, which can make the system have virtual forward-looking ability. GPWS provides the crew with corresponding warning tips when the aircraft approaches the ground danger, which increases the safety of the aircraft.

Precautions:
1. When the operating surface is unusable or poorly connected, red signs and red warning signs must be hung on the joystick (panel) and the bad parts.
2. When the engine is not lubricated, the hydraulic system is not lubricated with hydraulic oil, and some parts are not installed correctly, red warning signs should be hung on relevant control switches and defective parts.
Hang a red warning board on the missing parts. ?
4. Hang a red warning board on any control switch or circuit breaker that you don't want to operate.
