BAT Challenger 350 Practice Exam

The backup information supplied by the Integrated Standby Instrument is the essential trio that keeps you oriented and in control when the main displays fail: attitude, altitude, and airspeed. The attitude indicator shows your aircraft’s pitch and bank, the altimeter gives your current altitude, and the airspeed indicator shows your indicated airspeed. Together, these three parameters let you maintain level flight, stay clear of stalls, and avoid overspeed, even with the primary flight systems out.

Heading and vertical speed aren’t provided by this instrument in the typical standby setup (heading usually comes from a separate standby compass or directional indicator, and vertical speed isn’t a standard standby readout). Fuel quantity/range and engine performance/N1 come from other systems and displays, not the ISI.
