Which instrument monitors vertical speed in the ERJ?

The vertical speed indicator is the primary instrument for monitoring vertical speed in the ERJ. This instrument specifically measures the rate of climb or descent and is typically displayed in feet per minute (fpm). It provides critical information for pilots during all phases of flight, particularly during takeoff, landing, and when adjusting altitude during cruise.

The vertical speed indicator works by sensing changes in pressure as the aircraft ascends or descends, translating these changes into a visual representation that indicates the vertical speed. This allows pilots to make informed decisions about altitude changes and vertical maneuvers, ensuring safe flight operations.

In contrast, the altitude indicator displays the aircraft's current altitude but does not provide the rate of ascent or descent. The heading indicator offers information related to the aircraft's direction but is not concerned with vertical movement. The airspeed indicator measures the speed of the aircraft but does not relate to vertical speed or altitude changes. Therefore, the vertical speed indicator is uniquely suited for monitoring vertical speed in the ERJ.
