What does 起飞 mean?
起飞 (qǐfēi) is the verb 'to take off' — the action of an aircraft leaving the ground. The literal pair is 起 'rise' + 飞 'fly,' so the compound is transparent: rise-fly = take off. It's used for planes, helicopters, rockets, and (in modern slang) drones. Two notes for English speakers: first, 起飞 is intransitive — the plane takes off, you don't 'take off the plane.' The pilot doesn't 起飞 a plane; the plane 起飞 itself.
The opposite is 降落 (jiàngluò, land) or 着陆 (zhuólù, touch down). Second, in recent internet slang, 起飞 has acquired a figurative meaning: 'to take off' as in suddenly succeeding or going viral — 销量起飞 ('sales are taking off'). For everyday HSK use, stick to the literal aviation meaning. Common phrase at airports: 飞机几点起飞？('What time does the plane take off?').

Common phrases with 起飞
Don't confuse 起飞 with
起床 means 'get out of bed / wake up' — people getting up in the morning. 起飞 is for aircraft. Both start with 起 (rise) but the second character makes all the difference.
飞 alone means 'to fly' as a continuous action — birds flying, planes flying through the air. 起飞 specifically names the moment of takeoff. A bird 飞着 (is flying); a plane 起飞 (takes off) and then 飞 (flies).
