How many IASC computers does the Challenger 300/350 aircraft have?

The Challenger 300/350 aircraft is equipped with two IASC (Integrated Aircraft Systems Controllers) computers. This dual configuration is designed for redundancy and reliability, ensuring that critical systems on the aircraft remain operational even if one of the IASC computers fails. The presence of two IASC computers enhances the overall safety and performance of the aircraft, as they can effectively share the workload and provide backup in critical operations. This configuration is typical in modern business jets, where operational integrity is a priority. Having two IASC computers also allows for continuous monitoring and data validation, contributing to improved flight management and navigation systems.
