318 - ATPL Question Bank in English - Why can unintended leading-edge ice contamination create a serious stall risk during take-off rotation?

Question 318 - Principles of Flight - ATPL - Airline Transport Pilot Licence

Ice can reduce CLmax and the stall angle of attack while the aeroplane is increasing angle of attack at low airspeed, causing an unexpected stall.

Normal uncontaminated-aircraft rotation speeds always compensate fully for the ice.

Having all engines operating guarantees that the contaminated wing cannot stall.

Increasing angle of attack automatically sheds all leading-edge ice.
