🛫The glide slope, or angle of the descent plane provides the vertical guidance for the pilot during an approach
.
🛫It’s created by a ground UHF transmitter containing an antenna system operating.

🛫Like the signal of the localizer, so does the signal of the glide slope consist of two intersected radiation patterns, modulated at 90 and 150 Hz.

🛫However unlike the localizer, these signals are arranged on top of each other and emitted along the path of approach, as you can see in Fig above The thickness of the overlaping field is 0,7° over as well as under the optimal glide slope.

🛩️A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, combustion chamber is fed high pressure air by the compression system. 🛩️The combustor then heats this air at constant pressure. After heating, air passes from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the air is directly fed to the nozzle. 𝐀𝐧𝐧𝐮𝐥𝐚𝐫 𝐓𝐲𝐩𝐞 ✈️The most commonly used type of combustor is the fully annular combustor. Annular combustors do away with the separate combustion zones and simply have a continuous liner and casing in a ring. There are many advantages to annular combustors, including more uniform combustion, shorter size, lighter, and less surface area. Annular combustors tend to have very uniform exit temperatures. They also have the lowest pressure drop of the three...

Basic Clouds 🛩️Cloud type is determined by its height, shape, & characteristics. They are classified according to the height of their bases as low, middle, or high clouds, as well as clouds with vertical development. 🛩️Low clouds are those that form near the Earth’s surface and extend up to about 6,500 feet AGL. They are made of water droplets but can include supercooled water droplets that induce hazardous aircraft icing. Typical low clouds are stratus, stratocumulus, nimbostratus. Fog is also low cloud formation. This Clouds create low ceilings, hamper visibility, & can change rapidly. They influence flight planning & can make visual flight rules (VFR) flight impossible. 🛩️Middle clouds form around 6,500 feet AGL & extend up to 20,000 feet AGL. They are composed of water, ice crystals, & supercooled water droplets. Typical middle-level clouds include altostratus & altocumulus. These types of clouds are encountered on cross-country flights at highe...
