will learn that speeding up causes the sink reading on a TE vario to increase, as the glider is less efficient at higher
speeds, making it even more difficult to decide whether to speed up or slow down.
The "speed-to-fly" variometer takes the burden of this complex calculation away from the pilot, and although the
needle looks like it is behaving in a similar way to a TE or netto vario it is actually performing the triple compensation
calculations so the needle UP simply means SLOW DOWN, and the needle DOWN means SPEED UP. This is consistent
with the direction the needle would move if it were indicating underlying lift or sink, but the pilot no longer needs to
consider how much to accelerate or decelerate - the needle reads zero when the optimal airspeed is reached.
You will find more information in the complete C4 manual that is included.
AIRSPEED INDICATOR
The 510 degree scale on the airspeed indicator allows for a precise reading of the indicated airspeed in km/h or knots
depending on your FSX setting.
ALTIMETER
The altimeter is rather standard and like the Airspeed indicator can be switched
between metric and US settings. The gauge will automatically show the correct bitmap.
Make sure you set the correct QFE before take-off. As the C4 Competition works
independently from this gauge you could set QFE in this gauge and QNH in the C-4.
