Going Up and Going Down

Plane and Pilot

This climb speed is determined by minimizing the two sources of drag acting against the airplane. If speed is too low, meaning angle of attack is too high, induced drag builds up, as the wing is working extra hard to make lift. If speed is too fast, parasite drag becomes excessive, created from the increased wind resistance.

Powered-Lift Specialist XTI Explores Uncrewed, Magnetically Powered Aircraft

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.

Step-by-Step Guide to No-Flaps Landings for Pilots

Pilot Institute

Compared to standard landings, no-flaps landings require certain adjustments in aircraft handling, such as: Higher approach speeds (5-10 knots faster than normal). Flatter approach angle (due to less drag). For example, in a Cessna 172S, the approach speed increases from 60-70 knots with full flaps to 65-75 knots without flaps.

Naval Academy, approached the problem by setting lift-drag ratio, L/D, as his metric of efficiency. For instance, in the range of cruising power settings the specific fuel consumption of my Continental TSIO-360the rate of fuel flow required to generate one horsepowerimproves by about 1 percent with each increase in speed of three knots.

From Twinjet to Glider: Varied Experience Comes in Handy in Unwanted Transition

Flying Magazine

We had a 40-knot headwind, but using a conservative 10:1 glide ratio at FL 300, I knew we could make Page Airfield. I was 20 knots above gear speed, but I knew the gear could handle it. The gear is locked down, and I am still 30 knots over landing speed as well as overweight, but I have the runway made.

Wingtip Vortices and Wake Turbulence

Pilot Institute

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. Increased Drag Moving air around is hard work! This lateral movement takes place at a speed of about two or three knots.
