Recorded use
Wiktionary exampleThese source excerpts show how EAS appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.
470 kts is a known engineering constraint. The FCS is certified to 333 kts. However, a Loss of Control (LOC) will probably not occur unless the EAS is in excess of 470 kts, which will lead to an LOC due to over-gained and under-damped FCS gains.
