ISIS standby display shows which flight data?

ISIS standby display shows which flight data?

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

Answer: (A)

In the Airbus ISIS standby display, the essential flight data kept available as a backup are airspeed, altitude, attitude, and the landing system status. These four items are chosen because they give the crew the most critical references to control the aircraft when the main displays are unavailable: airspeed for managing lift and drag, altitude for situational awareness and safe clearance, and attitude to maintain the correct pitch and bank. The landing system indicator (gear status) is included to confirm whether the landing gear is down and locked during approach and landing, which is vital for a safe configuration. Engine parameters, heading/vertical speed, and fuel quantity with N1 are not part of the standby ISIS set. Engine data live on engine instruments or ECAM, heading is provided by the magnetic compass or standby compass, and vertical speed isn't a primary part of the standby trio.
