When is CLB thrust automatically set on the EICAS?

The correct answer states that CLB thrust is automatically set on the EICAS when the gear is up and the aircraft is above 400 feet AGL (Above Ground Level). This condition is part of the normal climb procedure for the Embraer Regional Jet.

When the landing gear is retracted and the aircraft has climbed above 400 feet AGL, it indicates a safe altitude where configuring the thrust to climb is optimal. This setting allows the engines to operate efficiently during the climb phase, promoting better performance and fuel economy. It also enables a smooth transition from initial climb thrust to continuous climb thrust, which is crucial for maintaining safe and efficient flight operations.

In contrast, the other scenarios do not reflect the conditions under which CLB thrust is automatically selected. For example, having the gear down or flaps extended suggests that the aircraft may still be in a landing or approach phase, which typically utilizes different thrust settings to ensure safe handling. When at cruising altitude, the thrust profile would have already stabilized and would not be affected by the gear position. Thus, understanding the automatic thrust management at various flight stages is essential for piloting and ensures adherence to operational protocols.
