Question:
Do the wheels continue spinning at a tangential velocity of 200 mile per hour after take off have any effect on an airplane? Are the brakes applied just before they are retracted?



Replies:
It varies from manufacturer to manufacturer. Some are allowed to spin down naturally, some are braked when retracted. A tire burst inside the wheel well is one of the failure modes that must be dealt with in the certification process.
