To prevent or mitigate active takeoff cracks, several strategies can be employed:
In high-altitude or cold-climate operations, aircraft structures may be "soaked" in sub-zero temperatures prior to takeoff. The sudden application of hot engine gases or frictional heating during the takeoff roll induces a thermal gradient. This differential expansion creates tensile stress on the colder, brittle outer surface, encouraging crack initiation. active takeoff crack
