This guide focuses on the DA42 TwinStar, equipped with Technify engines as well as the DA42NG and DA42VI, both equipped with Austro E4-B engines. The content is divided into three main sections: Multiengine Transition describes important concepts for multiengine aerodynamics, one engine inoperative procedures, and risk management associated with engine failure. The Systems Overview gathers important information from various parts of the Diamond Approved Flight Manual into a single, convenient location. The Flight Procedures section describes procedures and techniques refined by the author over years of dual instruction given in the DA42. These procedures are organized to follow the order of the Areas of Operation and Tasks found in the FAA Commercial Pilot Practical Test Standards.

*Covers lightplane performance flight testing methods, measures, and computer applications *Includes CD-ROM with sample spreadsheets containing equations to help readers perform their own flight tests *Describes GPS (Global Positioning System) test method for airspeed calibration and rapid-wind camera method for takeoff performance

The authors of 'Combat Codes' have painstakingly researched the codes used by the RAF to replace unit markings during World War II in order to attempt to confuse the enemy.

The Book The behaviour of helicopters and tiltrotor aircraft is so complex that understanding the physical mechanisms at work in trim, stability and response, and thus the prediction of Flying Qualities, requires a framework of analytical and numerical modelling and simulation. Good Flying Qualities are vital for ensuring that mission performance is achievable with safety and, in the first and second editions of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented, relating to both normal and degraded Flying Qualities. Fully embracing the consequences of Degraded Flying Qualities during the design phase will contribute positively to safety. In this third edition, two new Chapters are included. Chapter 9 takes the reader on a journey from the origins of the story of Flying Qualities, tracing key contributions to the developing maturity and to the current position. Chapter 10 provides a comprehensive treatment of the Flight Dynamics of tiltrotor aircraft; informed by research activities and the limited data on operational aircraft. Many of the unique behavioural characteristics of tiltrotors are revealed for the first time in this book. The accurate prediction and assessment of Flying Qualities draws on the modelling and simulation discipline on the one hand and testing practice on the other. Checking predictions in flight requires clearly defined mission tasks, derived from realistic performance requirements. High fidelity simulations also form the basis for the design of stability and control augmentation systems, essential for conferring Level 1 Flying Qualities. The integrated description of flight dynamic modelling, simulation and flying qualities of rotorcraft forms the subject of this book, which will be of interest to engineers practising and honing their skills in research laboratories, academia and manufacturing industries, test pilots and flight test engineers, and as a reference for graduate and postgraduate students in aerospace engineering.

Initially referred to as the Advanced Tactical Fighter (ATF), the F-22 was designed to meet a USAF requirement for 750 new fighters to replace the F-15 Eagle. Work began in the early 1980s, and competition selection resulted in orders for flying demonstration prototypes of the YF-22 and the Northrop YF-23. The first of two prototypes was flown on 29th September 1990, and extensive testing and evaluation took place during that decade. In 1993 an air-to-ground attack role using precision-guided munitions was added to the original air superiority role, and the designation has been changed to F/A-22 to reflect this. The F-22 is designed to supercruise at up to Mach 1.5 without use of the afterburner, and its unusual layout is designed for agility as well as to incorporate stealth characteristics. A planned two-seat trainer version, the F-22B was cancelled, but production deliveries are now taking place, with service introduction planned for 2005. Author Jay Miller has followed the program closely to produce an extensively researched and well-illustrated review of this topical new fighter in the well-established and acclaimed Aerofax style and depth.
