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.
: Over-rotating can cause a tail strike, while under-rotating eats up valuable runway. A smooth, continuous rotation to the target pitch is required.
Once a heavy jet begins to lose speed on an approach, its high mass means it requires a massive influx of energy (thrust) to reverse the trend. Conversely, once it gathers excessive speed, slowing it down requires significant planning. 2. Swept-Wing Aerodynamics: Blessings and Curses
It provides the foundation for handling the aircraft outside the normal flight envelope. Handling the Big Jets.pdf

The enduring value of the text lies in its structured approach to a flight profile. It takes the reader from the ground up through the most critical phases of flight. Takeoff and Climb Davies covers the critical nature of V-speeds ( V1cap V sub 1 VRcap V sub cap R V2cap V sub 2
: Always stay above the flight path of a preceding heavy aircraft. Jet engines produce very little thrust in the
The book dives into why specific regulatory standards exist, ensuring pilots don't just fly the plane, but manage its safety limits. Finding and Using the Text
Many advanced ATPL (Airline Transport Pilot License) training providers incorporate Davies' principles into their curricula. Conclusion
It seems you're referring to the well-known book by D.P. Davies (3rd edition, often in PDF format). Since I cannot open or access external files directly, I can instead provide a summary of the book’s key features based on its established reputation in aviation literature. A smooth, continuous rotation to the target pitch
Early turbojets could take up to 6 to 8 seconds to spool up from idle to full thrust. Davies emphasizes the absolute necessity of maintaining stabilized approaches to avoid being caught low and slow with no immediate power available.
When applying power, the jets don’t accelerate instantly.

First published in 1967 by David Peregrine Davies, the Chief Test Pilot of the UK Air Registration Board, this book was written to address a surge in training accidents during the early airline transition to first-generation passenger jets like the Boeing 707 and Douglas DC-8.
