The phrase "achieving flight" is correct and usable in written English.
It can be used in contexts related to aviation, space exploration, or metaphorical uses involving success or progress.
Example: "The engineers worked tirelessly on the new aircraft, and after months of testing, they finally celebrated achieving flight."
Alternatives: "gaining altitude" or "taking to the skies".
Likewise, man-made aircraft rely on these principles to overcome the force of gravity and achieve flight.
This is distinguished from certification flight testing, which is designed to formally validate system functionality and achieve flight readiness.
But of all the innovations brimming in toy vehicles these days, the most startling have been reserved for those that achieve flight.
The scenarios were compared in terms of flight time, control energy and number of maneuvers, flight distance, and achieved flight goals.
Both Mr. Lilienthal and Mr. de Gayardon died trying to achieve flight with winged outfits, as did Eric Stephenson, Ms. Weiss's mentor and fiancé.
Equipped also with high specific energy Lithium Polymer batteries, this fuel cell powered UAV is able to achieve flight durations close to 4 h.
Earlier this summer an anonymous air-traffic controller filing a report to Chirp, the industry's confidential whistle-blowing agency, claimed that pilots of low-cost airlines were cutting corners to achieve flight timetables.
The science: When it's hot enough at high elevations, the air will become too thin for laden airlines to take off (since planes achieve flight by pushing off of the air molecules around it). Days when extra precautions are taken are deemed "weight restriction days". Last month, for example, nearly 60 American Airlines flights were canceled in Phoenix over the course of three scorching days.
They would have achieved flight in a completely different way to birds and would have had a lower angle of take off and initial flight trajectory.
