There are distinct advantages to flying at high altitudes. These include decreased drag, faster true airspeed, and higher tailwinds (when applicable). However, these advantages bring with them a major disadvantage for any aspirated engine: a lack of air. Air pressure decreases at higher altitudes, and does so quickly. For example, at 18,000 feet elevation, 50% of the entire atmosphere is beneath your aircraft. This means there is much less oxygen for your engine to burn, resulting in a deficiency of horsepower. So, how do aspirated engines, engines that require oxygen to function, solve this problem? There are multiple ways, one of which is called turbo-normalization.
