Which instruments provide information for flight attitude in the ERJ-145?

In the ERJ-145, the instruments that provide crucial information for flight attitude are the attitude indicator and the altimeter. The attitude indicator displays the aircraft's orientation relative to the horizon by showing whether the wings are level or if the aircraft is climbing, descending, or banking. This is essential for maintaining proper flight control and ensuring stable orientation during various flight conditions.

The altimeter, while primarily indicating altitude, also plays a role in flight attitude, as altitude awareness aids in assessing the aircraft's vertical position relative to the horizon. Both instruments work together to give pilots the necessary information to maintain and manage the aircraft's orientation and altitude effectively.

In contrast, other options like speed and altitude indicators or heading and flight management systems do not specifically provide direct information about flight attitude. The vertical speed indicator, while important, only indicates the rate of climb or descent and does not convey orientation relative to the horizon. Thus, the combination of the attitude indicator and altimeter is fundamental for a complete understanding of the aircraft's flight attitude.
