Can the Challenger 300/350 aircraft hold in icing conditions with flaps extended?

The Challenger 300/350 aircraft is not permitted to hold in icing conditions with flaps extended due to potential aerodynamic issues that could arise. In icing conditions, the accumulation of ice on the wings and control surfaces can significantly alter the lift and drag characteristics of the aircraft. When flaps are extended, they change the airflow over the wings, leading to a higher risk of stall or control problems if ice is present.

Holding with the flaps extended in these conditions may exacerbate the situation, as the aircraft's stall speed increases due to the added drag and altered lift characteristics. It is critical for pilots to maintain the aircraft in configurations that ensure safe handling and performance, especially when operating in challenging weather conditions. Thus, the requirement to avoid extending flaps in icing conditions is a precautionary measure to ensure the safety and operational integrity of the aircraft.

Other scenarios that suggest limited holding capabilities or particular situations fail to account for the comprehensive safety protocols involved in flying in icing conditions.
