Which angle range should an Attitude Indicator be within after a startup check?

• A. +-5 degrees
• B. +-10 degrees
• C. +-15 degrees
• D. +-20 degrees

Answer: (A)

The angle range that an Attitude Indicator should be within after a startup check is within plus or minus 5 degrees. This limited tolerance is critical for ensuring the accuracy and reliability of the instrument readings. When pilots perform a startup check, it is essential that the Attitude Indicator is correctly calibrated and functioning properly, as it provides crucial information regarding the aircraft's orientation relative to the horizon. An indicator within this narrow range indicates that the instrument is aligned correctly and that there are no significant discrepancies that could mislead the pilot during flight. If the Attitude Indicator were to show a greater deviation, such as plus or minus 10 degrees or more, it could suggest a malfunction or misalignment that could compromise situational awareness, especially in low visibility conditions typical of IFR flight. Therefore, maintaining a strict tolerance of plus or minus 5 degrees ensures the instrument is providing reliable and precise information for safe maneuvering of the aircraft.
