Drag Knot Thrust 
Plane and Pilot

However, excess propulsive thrust, over that needed to maintain level flight, can be utilized to either increase speed or climb to a higher altitude. This climb speed is determined by minimizing the two sources of drag acting against the airplane. Although optimum, V Y is simply in the middle of a fairly broad lift-over-drag curve.

Archer Aviation’s Midnight and Joby Aviation’s S4, for example, are designed for short-hop flights cruising at less than 175 knots. The TriFan 600, by contrast, is expected to exceed 850 nm and 260 knots. This prevents tip vortices—a phenomenon where air leaks around blade tips, causing thrust loss and increased drag.

As I am executing the abnormal engine checklist and reviewing the single-engine procedures, the right engine rpm steadily decreases to below flight idle, and the aircraft is yawing significantly from the differential thrust. We had a 40-knot headwind, but using a conservative 10:1 glide ratio at FL 300, I knew we could make Page Airfield.

Since it’s a ratio, it doesn’t matter if you measure speed in knots, miles per hour, or meters per second. At sea level on a standard day (15 °C or 59 °F), sound travels about 661 knots (approximately 761 mph or 1,225 km/h). Here, Mach 1 is roughly 573 knots (about 659 mph). The Mach value stays the same.

The exhaust coming out of aircraft engines looks pretty dangerous, generating huge amounts of thrust and pushing back tons of hot air. This horizontal component of lift is called Induced Drag. Its called induced drag since it only exists as a consequence of lift. If youre generating lift, youre stuck with induced drag as well.

As they descended towards Leeds, the crew calculated the landing performance with the wind at 060 at 19 knots. The approach controller gave them the current wind as 070 gusting 33 knots and let them know that a Boeing 737-800 had just landed. And sometimes its 35 knots across *and* thick fog. It’s not *always* like that.

Although he was flying at or near the proper airspeeds for an overhead pattern, he was constantly moving the throttlesfrom near idle to near full thrust within seconds. During each turn, we lost about 1015 knots, but once wings-level again, the jet quickly accelerated back to 300. At least he didnt light the afterburners! Gusty winds?
