Davies avoids overly dense academic jargon. He writes from the perspective of a pilot who has stood on the precipice of aerodynamic limits and lived to tell the tale.
Piston engines provide near-instantaneous thrust response, and their propellers blow air directly over the wings, generating immediate lift. Jet engines do not.
Davies didn't just fly jets; he probed their very edges, exploring the realms of high-speed stalls, Mach tuck, and severe weather encounters to establish the safety limits that we now take for granted. He flew everything from the Fairey Swordfish biplane to the supersonic Concorde—which he described as "faultless"—and played a pivotal role in the flight testing of the Boeing 747, an aircraft he greatly admired. He also tackled the Vickers Valiant and other V-bombers to assess their potential for civil conversion. Handling the Big Jets.pdf
If you cannot find a clean copy of the original, or you want modern supplements, consider these books. They borrow heavily from Davies' principles:
Jet engines produce very little thrust in the lower percentage of their RPM range. The top 20% of engine RPM typically produces more than 50% of the total thrust. Davies avoids overly dense academic jargon
Another pillar of Davies’ essay is his skeptical view of automation. Writing at the dawn of the digital era, he predicted the "automation paradox." He argued that as flight decks became filled with computers, the pilot’s manual handling skills would atrophy. He coined the concept of the where crews trust the flight director blindly, even when the instruments fail.
To achieve high cruise speeds near the speed of sound, modern transport jets utilize swept wings. While sweeping the wings delays the onset of supersonic shockwaves, it introduces distinct handling penalties: Jet engines do not
If you download or purchase a copy of Handling the Big Jets , you will find that the bulk of the book focuses on the physical differences between propeller-driven aircraft and swept-wing jets. Several core topics define the text: Swept-Wing Aerodynamics
At high angles of attack, the wingtips of a swept wing tend to stall first. Because the tips are behind the center of gravity, this causes the lift center to move forward, forcing the nose to pitch up violently—a dangerous characteristic if not properly managed. 2. Thrust Response and Momentum
