🛫A sonic boom is the sound associated with the shock waves created whenever an object travelling through the air travels faster than the speed of sound.

🛫Sonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear.

🛫Sound travels in the form of wave in all directions.

🛫Imagine that a stationary aircraft has its engine ON , so the sound travels like sphere around the aircraft with each outer lining, representing a wave.

🛫When aircraft moves, the waves ahead of aircraft get compressed, but they do not averlap each other below the speed of sound.

🛫When it travels faster than speed of sound, the aircraft travels faster than these waves and the waves combine to form a single high energy wave called Sonic boom.

🛫This forms cone behind the aircraft called "Mach Cone".

🛫We can't hear the sound when aircraft passes over is , we can only hear it when the base of this cone reaches to us.

🛫We sometime can see a cloud form behind the aircraft, this is because of rapid change in air pressure which causes the drop in temperature and water vapor to condense and a cloud forms.

🛫a critical speed known as Mach 1, and is approximately 1,235 km/h (767 mph) at sea level and 20 °C (68 °F).

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

Glide Slope 🛩️glide slope of ILS is defined as a system of vertical guidance embodied in the Instrument Landing System which indicates the vertical deviation of the aircraft from its optimum path of descent. 🛩️A glide slope station uses an antenna array sited to one side of the runway touchdown zone. The GS signal is transmitted on a carrier signal. 🛩️The centre of the glide slope signal is arranged to define a glide path of approximately 3° above horizontal (ground level). The beam is 1.4° deep (0.7° below the glide-path centre and 0.7° above). 🛩️The pilot controls the aircraft so that the glide slope indicator remains centered on the display to ensure the aircraft is following the glide path to remain above obstructions and reach the runway at the proper touchdown point (it provides vertical guidance). 🛩️Two signals are transmitted on one of 40 ILS channels. One is modulated at 90 Hz, the other at 150 Hz. These are transmitted from co-located antennas. Each antenna
