Flight Instruments Used by Professional Aviators

Airplanes work with the help of an intricate system that we will call flight instruments. These devices, which allow professional aviators to safely sojourn through the clouds, use two main principles: rigidity in space or gyroscopic inertia (which provides stability while traveling on the air) and precession (which refers to the tilting prompted by external forces). 

As in most measuring devices, these flight instruments can be tweaked and customized depending on a particular aircraft’s needs. Here are some of the most common instruments used in the field of aviation. 

Altitude Indicator

This is one of the most common gyroscopic flight instruments. This indicator features a horizon bar representing the horizon and a miniature aircraft symbolizing the air vehicle. A gyroscope (which is a device composed of a wheel and axis) is also attached to the bar and relies on rigidity in space. It is the object in which the miniature aircraft rotates itself around. The position of the miniature aircraft indicates the orientation of the actual vehicle about the actual horizon. Altitude is displayed in meters or feet. Aviation experts regard this as one of the most critical instruments they use. 

Directional Gyro

As its name implies, this instrument is used to indicate direction. In this device, a gyro is aligned with a magnetic compass, allowing it to provide a more stable heading indication. The rotor of the gyro spins in a vertical plane and stays aligned with the direction set by the aviator. Its face also features a small, fixed silhouette of an airplane — the nose of which indicates the direction to which the aircraft is heading. 

Inclinometer

In the world of aviation, an inclinometer is a precise measuring device determining the angles of slope and tilt with respect to gravity. It measures the so-called yaw, which refers to an air vehicle nose’s side-by-side movement. An inclinometer for aviation facilities and aircraft is different than an inclinometer used by building contractors. To adjust the position of the incline, a professional aviator needs to step on a rudder pedal. To know which rudder pedal to step on, the aviator must check which side of the tube the indicator ball is located. The pressure on the ruder will prompt the indicator ball to return to the center. 

Turn Coordinators

One of the most fundamental flight instruments used by professional aviators is the turn coordinator, which also features a miniature airplane silhouette. The tips of the symbol’s wings indicate the level flight and the rate that the air vehicle turns. It is often canted at 30 degrees. Movements about the vertical axis signal that the aircraft is departing from a straight-and-level flight. 

Aviation instruments have come a long way from the original models used in the 1950’s and 1960’s, which we consider the early years of air travel. Since these early days, aircraft designers tried many custom designs for alignment tools and instrumentation. One inclinometer manufacturer in Philadelphia was instrumental in developing consoles for the US military and set the standard for what is used today.

Tools Used by Meteorologist to Predict Weather

Weathermen and women have been trying to predict the weather for years using various tools and instruments at their disposal. Mother nature does not disclose her secrets easily. In some corners of the earth, meteorologists are still relying on weather balloons and pibal theodolites to track their movements but in most of the developed world the tools used are much more advanced. Below are some of the tools employed for the task of weather prediction.

Doppler radar

When it comes to severe storms, meteorologists use a doppler radar. This radar tracking system is able to gather velocity data of various kinds of storms, any airborne particles, and even how the thunderstorm clouds rotate, as well as the strength and direction of the wind. 

Disdrometers

A disdrometer is an example of an optical alignment instrument used by meteorologists. This instrument uses light to measure droplet sizes of precipitation from a distance. It measures the size distribution and the velocity of hydrometeors in the meteorological parlance, most commonly known as raindrops. 

Radiosondes

A meteorological radiosonde helps predict weather by acquiring upper-air data and sending this data to a ground-based receiver. Radiosondes are tied to weather balloons and are released twice a day in 92 locations around the United States. Its trip usually lasts about two hours and during that time, it collects data like wind speed, wind direction, air pressure, relative humidity, and temperature. Meteorologists then use this to predict the weather in the coming days with the help of data modelling. 

Satellite data

Weather satellites are loaded with custom optical equipment used by scientists to analyze our weather. The National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service operates about three kinds of weather satellites. This includes deep space satellites, geostationary satellites, and polar orbiting satellites. 

Supercomputers

The NOAA also uses the Weather and Climate Operational Supercomputer System (WCOSS), which is mainly responsible for modern forecasting. It has a 5.78 petaflop computing capacity, which is enough processing power to conduct quadrillions of calculations every second. NOAA’s supercomputers are so powerful that they can process data six million times more than your average computer at home. 

Automated surface-observing systems

Automated surface-observing systems are tasked to monitor the Earth’s surface for varying weather conditions. In the United States alone, there are over 900 locations that can record surface visibility, temperature, precipitation, and other sky conditions. 

Advanced weather information processing system

Another tool used by the NOAA is the advanced weather information processing system. This is a computer processing system that has the ability to combine the data from all these different tools and turn them into a graphical interface so that scientists and meteorologists are better able to analyze the data gathered. Because of this, weather forecasts become more and more accurate. 

All of these tools are important, and each serves its own purpose. Scientists and meteorologists have once found digital theodolites for sale and attached a radiosondes instrument to a weather balloon for their primary source of data gathering. These one second theodolites are highly accurate but limited in the data they can capture. Today meteorologists rely heavily on a manufacturer of precision alignment equipment that can handle custom designs for measuring equipment. Warren Knight Industries has been doing that work for over 90 years.custom designs for measuring equipment
