Why Aircraft Engine Preheating Is Important ?

While modern aircraft engines are quite reliable and powerful, they tend to experience more trouble when operating in colder conditions. This is due to the fact that modern engines still rely on the combustion of fuel and air mixtures to generate thrust, and colder conditions can deter the efficiency and startup speed of assemblies as they begin to operate. Because of this, it is common to preheat engines to get them warmed up before flight which can lead to a number of benefits and improvements to flight reliability.

The process of preheating engines and whether or not it is needed is often a point of contention for many pilots, and the consensus is often that the benefits depend on how cold the aircraft engine is and how you choose to heat it up. Despite this, it is clear to see why engine preheating is important in certain situations when you consider the properties of various substances and materials that make engine operation possible.

For example, engine oil is essential for standard engine functionality and efficiency, especially at sub-freezing temperatures where oil begins to thicken. This results in engine parts having a harder time being lubricated, potentially leading to increased damage as parts move across one another with less protection and increased friction. Additionally, engines feature a wide variety of metals for their construction, each of which may differ in terms of how they expand and contract with temperature. By heating up the engine to a set and even temperature, one can ensure that materials do not come too close together with mismatched shifting. Beyond such examples, there are also various instruments and electronics that may have deterred performance as a result of the cold, further making heating assemblies an important action to take.

While the why is now more clear, there is still the debate over when it is best to carry out engine preheating procedures. If one were to consider the stances of manufacturers, even those can vary. While Lycoming recommends preheating engines when they are cold-soaked to 45 degrees Fahrenheit or lower, Continental states that engines should be preheated once they have been sitting at 20 degrees Fahrenheit or lower for more than two hours. As these two statements widely vary in regard to what time is best, it can be beneficial to make your decision based on the type of aircraft engine you operate and what the manufacturer of that specific model recommends.

For the actual preheating of the engine, there are a few options that one has. The most optimal is a heated hangar, though this may not be feasible for many. As such, one can also utilize an oil pan heater and heated bands that are placed around cylinder bases, and this system is lightweight and easy to use. In other instances, you can use trouble lights that give off heat through transfer into the ambient air, and this can help warm up parts. Alongside such examples, other various products exist, and the choice may come down to ease, cost, and other factors. Nevertheless, never use any product or method that may cause damage to parts or any change that can render the aircraft unsafe or unfit to fly.
