DVD-08 :: Basic Autorotations
  • DVD-08 :: Basic Autorotations

Please note: This DVD was filmed and produced in the 1990s.  We are currently in the process of improving our DVD training material to a more contemporary format, with some exciting stunning footage!  In the meantime the content is still highly relevant to any pilot learning to fly a helicopter today!

 

This DVD gives an introduction into Engine-off landings in a helicopter and how to land safely. The Advanced Autorotations covers more advanced and complicated engine failures, autorotations backwards, 360 degrees, with turns etc.

Duration: 1 Hour 10 mins

This presentation covers the steps a pilot should follow in order to execute a controlled landing after an engine failure in flight. The viewer gains the benefit of two instructor’s experience, shared through detailed board briefs. The initial entry into autorotation, the approach and the landing are described in terms of the aerodynamic principles involved. Pilots are reminded that the machine still ‘flies’, the only difference being that it is now in a controlled, constant descent. The briefs will allow you to gain a deeper understanding of what happens to the rotor disc and total rotor thrust during a flare, and how the three ‘flare effects’ work to arrest the rate of descent as well as wiping off the forward airspeed.

The briefs are ideal for a student pilot, new to autorotations, and handy for experienced pilots who have not done one in a while. Pilots who are training to become instructors will also find this presentation invaluable in aiding their onward teaching.

On the more technical side, the finer points of rotor RPM control are outlined. Engine handling, especially near the end of the autorotation, if the needles are to be re-joined, is a serious matter for pilots and aircraft owners / operators who conduct multiple autorotations, as seen for instance, in a training environment. A note is made of the different handling requirements of low inertia rotor systems, such as on the popular Robinson R22, compared to the high inertia Bell 47.

Through vector diagrams, the instructors demonstrate how the rotor blades are divided into different sections during autorotative flight. A useful explanation of the height-velocity graph, more commonly known as “ the dead mans curve”, helps pilots understand why they need to be operating out of the ‘shaded areas’, and what the consequences may be if they chose to operate within them. For instructors and students alike, some common faults are outlined. The intention is to make pilots more aware, and therefore more empowered to take corrective action before it is too late.
