Introduction
Visibility is the most important weather factor to all aviators since it takes a part in essential role in takeoffs, approaches, and landings. Visibility is defined as the aviator's ability and possibility to identify and spot the objects during the day and night over hundreds of miles, meters, and feet.
Low ceilings and poor visibilities have lead to many aircraft accidents. Fog, heavy snow, heavy rain, ash clouds, blowing sand, and blowing dust all control the visibility and result in low ceilings. In order to understand the topic in a better way, below are the definitions of both terms “Visibility” and “Ceiling”:
• Visibility: the range in which aviator can define and see the objects.
• Ceiling: the height of the closest

Higher altitudes can also increase the possibility of ice formation either on the wings, which can limit the aircraft’s ability to produce lift, or on sensors which track airspeed and altitude. Higher altitude air is also harder to breathe, which is why aircraft are pressurized.
How the particular weather phenomenon can be avoided? How it's observed, reported and predicted? And how pilots get informed about it in the atmosphere or on the ground?
Satellites, weather balloons and ground radar have been used to both forecast future weather and update current conditions for decades. Ground-based weather radars transmit a signal, then detect and analyze the returning echo to assess the size and concentration of water droplets as well as wind speed.
Because weather patterns can form and dissipate quickly, and weather analysis can be difficult at longer distances, aircraft are being increasingly equipped with on-board systems called Airborne Weather Avoidance Radar (AWAR).
While AWAR is useful for a pilot to get nearby weather information, it is also limited in both the direction and range at which it can detect wind or rain.
In addition to weather detection and avoidance technology, communications systems are a key tool for pilots to receive and share
Although Greensburg was almost entirely destroyed, the storm helped to reinforce the important role that storm chasers play in the tracking and warning process of severe weather. By having well-trained, experienced people in the field, meteorologists and weather services are better able to track the exact location and characteristics of tornadic events, relaying that information to the public faster and more accurately than ever before.
Higher altitudes—the higher aircraft flies, leaner the air and the greater the angle of attack is necessary for producing the lift needed to preserve the flight level.
It was the first radar to be used in any combat ever. It was originally used on overcast foggy days or any nighttime
UAVs save lives and gather data when fully utilized. Because residents need as much time to prepare for a tornado, scientists developed the UAVs. For example, when a tornado tore through Moore, Oklahoma, last May 20, residents had 16 minutes in advance to prepare for the tornado. On average, an alarm sounds 13 minutes before a tornado strikes. Three minutes may not sound like a lot of time, but every second counts before a tornado strikes. By developing UAVs, scientists look for ways to give people more time to find safety before a tornado hits. “The ultimate goal is to increase warni...
Although I, like many professional meteorologists, know that these comments are small jokes, it does bother me that the public, or at least a mass of the public hold a common perception that meteorologists just cannot be correct with their forecasts. Maybe I am getting too defensive, but listen to me when I say meteorologists have the burden to predict the unknown. It is not an easy task, nor is the countless hours of physics, calculus, differential equations, exponential mathematics, and chemistry easy to comprehend and learn. Meteorologists take their jobs very seriously as they are essentially the ‘spokesman’ for the weather and an elit...
Weather conditions- Sometimes the bad weather conditions become the huge problem for the aircrafts as they are not able to operate in bad conditions by which they get losses.
The Weather at DFW Airport said, “On final approach to runway 17L at DFW Airport, flight 191 penetrated a weather cell containing a thunderstorm with a heavy rain shower.” Because of the evidence that two weather cells (Cells “C” and “D”) were present north of runway 17L, the Safety Board examined the possibility that Cell “C” might have masked Cell “D” from flight 191s flight
Icing, or ice buildup on the wings, is a particular problem for aircraft. When ice builds up on wings, it can disrupt airflow, robbing an airplane of lift and can decrease its angle of attack, which keeps it in the air.
In aviation, radar system used to detect aircraft, weather formations and terrain. Radar system uses radio waves to determine the range, altitude, direction and speed of objects. Primary Surveillance Radar (PSR) and Secondary Surveillance Radar (SSR) are installed in ground-based Air Traffic Control (ATC) radar system. PSR is a radar system that detects the positions of the aircraft within the control area and weather conditions. SSR is a radar system that detects the positions of the aircraft and receives additional information, for example, the aircraft's identity, altitude and distance. Both PSR and SSR antennas are co-located and work as an integral system. The Raytheon Airport Surveillance Radar (ASR-11) is a National Airspace System (NAS) certified ATC radar system and deployed worldwide to over 125 sites.
Measurement approach- taking a range of temperatures over time, reading and observing the situation, also to assess the situation by getting expect advice and suggestions. Taking the maximum and minimum weather conditions implementing a plan based on this information. Triggering an evacuation alarm.
Altitude illnesses are usually caused by ascending to high to fast. What occurs in the body is that as you go higher in altitude the oxygen molecules remain the same but the barometric pressure decreases. This reduced pressure does not allow as much air into your lungs, which can therefore not absorb as much oxygen as the body needs. (Curtis, 1999). Hypoxia refers to a state in which oxygen supply is insufficient and hypoxemia is specific to low arterial oxygen supply (West, 1977). The figure to the following page shows the pathophysiology or the functional changes that accompany AMS and HACE (Basnyat & Murdoch, 2003).

The weather forecasters use probability and statistics just as much if not more than any other field on earth. As weather patterns are not fully understood and are dynamic, analysts have to rely heavily on past weather systems and patterns to “guess'; or estimate the possibility of present weather systems to behave in similar manners. If the probability of its behavior, subject to certain factors, in one manner over another is high forecasters make decisions as to how to advise the public.
