expedite(redirected from Expeditus)
Also found in: Dictionary, Thesaurus, Medical, Wikipedia.
An expression used by ATC (air traffic control) on radio to direct the pilot to promptly comply with an instruction (but keeping safety factors into consideration) to avoid the development of an imminent situation. In short, it means hurry up. “Expedite climb/descent” normally indicates to a pilot that the approximate best rate of climb or descent should be used without requiring an exceptional change in aircraft-handling characteristics.
