2.2 — Level Flight, Thrust & Power Required

Key insights

Key ideas from this lesson:

• In level unaccelerated flight, thrust required equals drag; power required equals drag × velocity.
• Increasing weight raises both thrust and power required across the speed range.
• Jets and propellers behave differently: thrust vs power engines shift the best-range and best-endurance speeds.
• Flying at the minimum-drag speed maximizes glide and efficiency margins.
