The Advanced 206 introduces systems and flight dynamics never before seen in a Microsoft flight simulator including torque yaw, LTE and rotor droop.
Before you even leave the ground you will notice that the Advanced 206 flies differently to other FS9
helicopters ; the aircraft will have a strong
yaw tendency as it becomes light on the skids. A degree of pedal input will be require to maintain a constant heading during
a hover or at low airspeed and this needs to be balanced as the collective moves. During forward flight other aerodynamic factors come into play and the torque effect will reduce.
Notice too that the amount of pedal input affects the power available at the main rotor!
or "transient power droop". Pull the collective aggressively and you will lose precious rpm as the governor tries to catch up with the increased power demand. Recoverable if you have altitude and forward speed, terminal if you are low and slow.
VORTEX RING STATE
(VRS)Descending too quickly with too little forward airspeed can result in the aircraft entering its own downwash, the results can be catastrophic, recovery is possible with enough height available and it can be avoided using aggressive side-slipping.
A tailwind can give you a few surprises, even worse when combined with LTE
or "loss of tail rotor effectiveness". . LTE can result in a sudden yaw about the rotor mast and lead to a catastrophic loss of control. This occurs when the increased demand for pedal input suddenly disappears as the aircraft leaves LTE. The best defence is to understand the causes and to promptly take the correct actions if you suspect LTE. Wind direction and speed must always be considered during a hover.
TAIL ROTOR VORTEX RING and
MAIN ROTOR VORTEX INTERFERENCE
Are the causes of LTE you are most likely to experience. These are explained in detail in the product manual.
LOSS OF TRANSLATIONAL LIFT
While it has a relative headwind the aircraft produces more lift (translational lift). The sudden yaw of LTE causes a dramatic loss of this lift as the aircraft turns away from the wind. The spinning aircraft will drop unless the pilot adds collective; but remember what we said about rotor droop.
