Wankel engines operating within their original design parameters are almost immune to catastrophic failure. A Wankel engine that loses compression, or cooling or oil pressure, will lose a large amount of power and fail over a short period of time. It will, however, usually continue to produce some power during that time, allowing for a safer landing when used in aircraft. Piston engines under the same circumstances are prone to seizing or breaking parts, which will almost certainly result in catastrophic failure of the engine, and the instant loss of all power. For this reason, Wankel engines are very well-suited to snowmobiles, which often take users into remote places where a failure could result in frostbite or death, and in aircraft, where abrupt failure is likely to lead to a crash or forced landing in a remote place.
