ISIS provides a standby display for which of the following?

ISIS provides a standby display for which of the following?

• A. Engine parameters only
• B. Airspeed, altitude, attitude, landing system
• C. Heading and vertical speed
• D. Fuel quantity and N1

Answer: (B)

The standby instrument system is meant to provide the pilot with essential flight data as a backup when the primary displays are not available. It presents four key indications: airspeed, altitude, attitude, and the status of the landing system. This combination gives you the speed to manage on approach or climb, the altitude to control vertical position, the attitude to maintain proper pitch and bank, and the navigation/landing guidance status to help you execute an approach or continue safe flight even with degraded displays. The other options rely on engine parameters or omit the critical standby data, so they don’t reflect what ISIS is designed to provide.
