How much altitude is typically lost during an airstart attempt at 125 KIAS?

During an airstart attempt at 125 KIAS, it is typical to lose around 1200 feet of altitude. This is a standard figure based on performance data and the characteristics of the aircraft during an airstart procedure. When executing an airstart, the aircraft experiences a significant decrease in altitude due to the aerodynamic forces acting on it and the time required to initiate the restart process. The altitude loss varies with different factors such as aircraft configuration, weight, and environmental conditions. By having a clear expectation of losing approximately 1200 feet, pilots can effectively manage their descent and assess the likelihood of a successful airstart in the context of their current altitude and safety margins. This information is critical during training and actual flight operations to ensure proper decision-making and to maintain situational awareness.
