According to the FAA Glider Handbook, a glider pilot should keep the glider in one of two positions when being towed to altitude. It should either be in a “low tow” position, wherein the glider is just below the wake from the towplane, or it should be in a “high tow” position, just above the wake from the towplane. Hold this position carefully to keep from dragging the towplane around!
A glider pilot must watch the wind and the slope of the terrain carefully to hold inside the upward-moving currents of air, using the lift of the air flowing up the mountain slope to hold the craft aloft. With a good 25-knot wind set in the simulator, you can get a nice, free elevator ride to 10,000 feet when flying along the windward side of a nice, steep mountain. This is called ridge lift.
X-Plane will also model the columns of rising hot air, called thermals, that are useful for prolonging a glider flight. To turn on the thermals, open the Weather dialog box from the Environment menu. Select the set weather uniformly for the whole world radio button, then drag the thermal coverage slider up—15 percent coverage or more makes for a nice flight. A 500 ft/min thermal climb rate is fine, but you can raise that value, too, if you like. Additionally, as you’re starting out in gliders, you may want to keep the various wind speed, shear speed, and turbulence sliders set to minimum.
Now, to take full advantage of both ridge lift and thermals, gliders have a unique instrument known as the total energy variometer. This indicates your glider’s rate of climb or descent. You can see the visual representation of this instrument in the panel (it is labeled “Total Energy”); if the needle is above the center of the dial, you are climbing (perhaps due to ridge lift or a thermal), and if it is below the center, you are falling. Even better, you can flip on the switch labeled “Audio” in the instrument panel to get auditory feedback from the variometer. If it is beeping, then the aircraft is in a nice updraft from the air following the terrain. Circling in that area will let the glider ride the climbing air to altitude. When the variometer is emitting a steady tone, the craft is in descending air—the glider has been blown to the wrong side of the mountain, and a crash will follow soon if you do not find a way out of that area! |
