3.4.1.4 Increased Low Speed Sensitivities

At low or hovering speeds the helicopter’s cyclic and anti-torque pedal controls become more

sensitive and have a greater effect on the helicopter’s behaviour. Pilots must be finely attuned to

the behaviour of the aircraft at these low speeds and constantly make small subtle changes to the

controls, anticipating their effects. Over-control can result in “Pilot Induced Oscillation” otherwise.

As airspeed increases, the turbulent air generated by the rotor wash is left behind the airframe and

the helicopter becomes more stable and requires less constant inputs to correct its attitude.

3.4.1.5 Accrued Wear and Damage

When enabled by the difficulty setting and operating in “Cumulative Wear” mode, (set via the

“Settings” menu option), exaggerated use of collective pitch, aggressive tail rotor pedal input and

engine misuse can result in wear and damage occurring to the helicopter. If “Failure hints” are

enabled in the Settings dialog, the pilot shall be alerted to conditions where wear or damage is

accruing as they occur via the text information line at the top of the main program window.

3.4.1.6 Mechanical Failures

As wear to either the engine, main or tail transmission systems approaches a critical point, the

relevant annunciator “chip” light will illuminate, indicating that metal debris has been caught within

the system’s magnetic oil trap and that physical damage has occurred to the system. Should a

critical point beyond that be reached then the system may fail completely. Failure in flight will result

in a mechanical grinding noise emanating from the system and the pilot will have to attempt to land

immediately.

Important note: Additional failures can be triggered using timers in the DodoSim Failures menu

item dialog. This section describes only those failures that can be caused by pilot input through

misuse when “Cumulative Wear” mode is selected and the difficulty level permits failures.
