MESA Airlines E-175 Ice UPDATED MAY 2021What sources are used for aircraft anti-icing and de-icing? - correct answer Bleed air and electric heat What uses bleed air for ice protection? - correct answer Engine lips and 3 outboard slats on either wing What uses electric heat for ice protection? - correct answer Pitot-static, windshields, water lines and pressurization static port If an engine fails does the opposite wing and engine receive ice protection? - correct answer Yes. The crossbleed valve opens to provide symmetrical ice protection for both wings. The failed engine does not receive heat to the engine lip How many ice detectors must be working to have ice detection? - correct answer One. There are two for redundancy How long will the de-icing system remain on after icing is no longer detected? - correct answer 5 minutes If ICING on the MCDU is set to OFF and on takeoff roll icing conditions are encountered, will the de-icing system turn on? - correct answer Not until 1,700 ft or 2 min after takeoff Can the APU be used to provide bleed air for de-icing? - correct answer No What is protected from ice and rain? - correct answer - Engine inlets - Wing leading edge - Smart probes and total air temperature probes - Windshields - Water and waste drain systems Is the ice protection system automatic? - correct answer Yes, under normal conditions Can the pilot override the automatic ice protection system? - correct answer Yes How is ice detected in flight? - correct answer 2 ice detectors vibrate constantly and have a sensor that will detect a change in vibration due to ice accumulation on the device. Once ice is detected, the sensor element heats and melts the ice. The cycle will repeat anytime ice accumulates on the sensor What compressor stage is bleed air tapped for ice protection? - correct answer 10th stage high stage valve How is bleed air directed for pneumatic anti-ice? - correct answer Engines are independent, wings use onside bleed What happens if there is a single bleed source failure? - correct answer The crossbleed automatically opens How should the MCDU be set if there are icing conditions present on the ground? - correct answer ALL What does selecting ALL on the MCDU provide? - correct answer Engine anti-ice when engines are running and wing anti-ice when wheel speed 40kts If ALL is selected on the ground, at what point will the anti-ice system become automatic? - correct answer 1,700 AGL or 2 min after takeoff
