The correct answer is: C. 35 kmph
The International Civil Aviation Organization (ICAO) has set a limit of 35 knots (65 km/h) for the crosswind component of the wind at airports serving large aircraft. This limit is based on the safety considerations of landing and taking off in crosswinds.
A crosswind is a wind that blows perpendicular to the runway. When an aircraft is landing or taking off in a crosswind, the pilot must compensate for the sideways force of the wind. This can be difficult and dangerous, especially for large aircraft.
The ICAO limit of 35 knots is based on the assumption that large aircraft can safely land and take off in crosswinds of up to this speed. However, there are other factors that can affect the safety of landing and taking off in crosswinds, such as the type of aircraft, the runway conditions, and the pilot’s experience.
It is important for pilots to be aware of the crosswind component of the wind before landing or taking off. They should also be aware of the ICAO limit and the other factors that can affect the safety of landing and taking off in crosswinds.
The other options are incorrect because they are not the ICAO limit for the crosswind component of the wind at airports serving large aircraft.
