Handling The Big Jets.pdf May 2026

"Handling the Big Jets" by D.P. Davies is a foundational 1967 aviation text detailing the distinct flying characteristics of jet transport aircraft compared to propeller-driven planes. The book covers critical areas including engine lag, high-altitude aerodynamics, and landing, serving as a primary training resource for pilots.

1. Summary of Key Concepts from the PDF (useful for quick reference)

• Thrust response lag: Unlike piston or turboprop engines, early jets had slow spool-up time. Davies emphasizes anticipating power changes before they're needed.
• Drag in turns: Even modest bank angles (20–25°) significantly increase drag in a clean, swept-wing jet. Requires proactive thrust management.
• Deep stall avoidance: A classic chapter on T-tail aircraft where the wing downwash blankets the tail, preventing pitch-down recovery. The PDF stresses recognition (low buffet, high pitch, high descent rate).
• Backside of the drag curve: Slow flight in a jet (e.g., after takeoff or holding) demands attention—excess drag can make acceleration impossible without altitude loss.

Introduction

Taxiing and Ground Handling

• The aircraft must be fully configured (gear down, flaps set) and on speed early in the final approach.
• "Dive and Drive" techniques suitable for smaller aircraft are lethal in jets.
• Going Around (Missed Approach): Due to engine spool-up time, the decision to go around must be made early. Davies famously emphasizes that "the only thing you run out of in a jet is altitude and ideas at the same time."
