PSA Airlines Canadair Regional Jet Systems (PSA-CRJ) Practice Exam

Does the wing anti-ice cross-bleed system allow one engine to provide anti-ice protection to both wings?

1. True

2. False

3. Only during takeoff

4. Only at high altitudes

The correct answer is: True

The wing anti-ice cross-bleed system is designed such that one engine can indeed provide anti-ice protection to both wings. This system operates by utilizing bleed air from the engines to heat the leading edges of the wings, preventing ice accumulation during flight under icy conditions. When one engine's bleed air is directed to the anti-ice system, it enables both wings to receive the necessary heat for de-icing, thus enhancing safety and performance during critical phases such as climb and cruise. The effectiveness of this system is particularly important during operations in cold-weather environments, where ice can create significant aerodynamic issues. The ability to share the anti-ice capability between the wings through this cross-bleed configuration means that even if one engine is not operating at full capacity or is temporarily malfunctioning, the remaining engine can still maintain effective ice protection across both wings. This redundancy plays a critical role in overall aircraft safety and operational reliability.
