       Discussion 9.2: Microburst  

A microburst is a localized column of sinking air (downdraft) within a thunderstorm and is usually less than or equal to 2.5 miles in diameter (NWS, 2016, P. 1). There are two types of microbursts, dry and wet. Microbursts are formed usually with a storm. A large “core” is formed by an updraft of wind, once the core becomes too heavy with rain and potential hail, the core collapses causing an extreme down draft. This large downward force can surpass one-hundred miles per hour. Microbursts can be detrimental to any size aircraft. No aircraft can climb at the rate and down force that the microburst is applying. Weather can see potential microbursts forming from converging air, unfortunately microbursts form quickly and stop just as fast. Avoiding this weather phenomena is difficult, Ascending and descending through cloud layers effects visibility. Noticing down pressure can be observed by the force of precipitation falling and by what is happening on the ground level. With minimal visibility in cloud layers or possible thunderstorms can hinder, in which, possible microburst identifiers would go unnoticed and be too late. Microbursts are highly dangerous and should be avoiding at all cost. If a microburst can damage homes on the ground, imagine what the damage can be done to an airborne aircraft.

Air Traffic Control Entities

ASCI 202: 8.2 Air Traffic Control Entities        Discussion 8.2: Air Traffic Control Entities                  There are many entities intertwined into aviation. Flight data and local control are key factors in the safety of the pilots, their aircraft, and the passengers onboard.   The positions in the tower have very different roles to play but are alike in some ways. Aviation revolves around the safety and both these positions determine that factor             Flight data’s primary duties include coordination with ground and local control, notifying agencies that an emergency occurred, and coordination with different facilities, such as; departure and approach. Flight data can be the most difficult position in the tower at times, recording information and relaying as needed can become hectic. Emergency aircraft in need of medic...

Loss of Elevator

                The loss of elevator control can be critical to an untrained pilot. The elevator in a fix-winged aircraft allows the aircraft to adjust altitude, up and down. The impact of losing the elevator can cause mid-air collisions, unable to land, and incapable to gain or loss altitude. To a trained pilot, the impact of losing the elevator is very miniscule. With a few steps the pilot can regain control of the aircrafts altitude by using the aircrafts flaps and trim.   “Throughout aviation history, there have been a few accidents due to primary control system failures. In many examples, pilots were able to maintain aircraft control through abnormal power, flap, and trim settings.” (What Can You Do If You Lose Elevator Control?, 2019, Para. 7). The pictures above shows the steps to adjust altitude with elevator failure. To raise the nose of the aircraft, the pilot must apply nose-up trim;...
