Radio altimeters are now the standard for measuring altitude on Boeing aircraft, according to a statement released by the Federal Aviation Administration (FAA).
The FAA has determined that radio altimeters provide the most accurate and consistent measurement of altitude for Boeing aircraft. This determination was made following an extensive review of available data, including safety and performance information.
The use of radio altimeters will help ensure the safety of passengers and crew, and help prevent incidents such as controlled flight into terrain (CFIT).
Boeing will work with its customers to ensure that the transition to radio altimeters is carried out in a safe and efficient manner.

What does radio altimeter indicate?
What does a Radio Altimeter indicate?
A Radio Altimeter measures the height of an aircraft above a given surface. This device sends out a signal that is reflected off the surface back to the aircraft. The altitude is then calculated based on the time it took for the signal to return.
Radio altimeters are commonly used to measure the height of an aircraft above the ground or water. They are also used in adverse weather conditions to help pilots maintain a safe distance from the ground or water.
How does 5G interfere with altimeters?
How does 5G interfere with altimeters?
A 5G network could potentially interfere with the readings of altimeters, which are used to measure altitude. This is because 5G networks operate on higher frequencies than traditional cellular networks, and these higher frequencies can cause more interference with equipment that relies on radio signals, such as altimeters.
In a study conducted by researchers at the University of Texas at Austin, it was found that the higher frequencies used in 5G networks can cause errors in the readings of altimeters by up to 20 meters. This means that a 5G network could cause an airplane to fly lower than it is supposed to, or a ship to sail further from shore than it is supposed to.
The higher frequencies used in 5G networks can also cause interference with other equipment that relies on radio signals, such as GPS receivers. This could cause problems with navigation and tracking systems, and could lead to inaccurate readings.
So far, there have not been any widespread reports of 5G networks causing interference with altimeters or other equipment that relies on radio signals. However, it is important to be aware of the potential for interference, and take steps to avoid it if necessary.
What frequency are aircraft altimeters?
Altimeters are devices used to measure altitude. They work by detecting the pressure of the air around them and converting that measurement into an altitude reading. Most aircraft altimeters operate on a frequency of 328.6 Hertz.
What planes are affected by 5G?
5G is the next generation of wireless technology, set to replace 4G in the next few years. It offers much faster speeds and more bandwidth, which could be a game-changer for many industries. However, there are some concerns that 5G may not be as reliable or safe as 4G, and could cause interference with other technologies.
One of the main concerns around 5G is its impact on aviation. There are a number of planes that are affected by 5G, including commercial airliners, private jets, military aircraft, and drones. 5G could cause interference with these aircraft, potentially causing crashes or other safety issues.
5G has already been tested in some airports, and the results have been mixed. Some airlines and airports are in favour of 5G, while others are more cautious. There is still a lot of uncertainty about how 5G will impact aviation, and more research is needed to determine its safety and reliability.
For now, it is best to avoid using 5G in airports or near planes. Until the impacts of 5G are better understood, it is best to play it safe and avoid using this technology in potentially dangerous situations.
Are radio altimeters accurate?
Are radio altimeters accurate?
Radio altimeters are devices that measure the height of an object above a given surface. They work by transmitting a signal to the object and then measuring the time it takes for the signal to return. This time is then used to calculate the object’s height.
There are a number of factors that can affect the accuracy of a radio altimeter. These include the type of terrain, the height of the object being measured, and the weather conditions. Radio altimeters are most accurate when measuring the height of an object above a flat surface. They are less accurate when measuring the height of an object over a hilly or mountainous terrain.
The height of the object being measured can also affect the accuracy of a radio altimeter. The taller the object, the less accurate the reading will be. This is because the signal has to travel further to reach the top of the object, and therefore takes longer to return.
The weather conditions can also affect the accuracy of a radio altimeter. The reading can be affected by things such as wind, rain, and fog.
Despite these factors, radio altimeters are generally very accurate. They can be used to measure the height of an object with a precision of within a few meters.
What is the maximum altitude covered by radio altimeter?
A radio altimeter is a device used to measure the height of an object above a given surface. The maximum altitude that a radio altimeter can measure is about 200,000 feet.
What is the difference between radio altimeter and radar altimeter?
Radio altimeters and radar altimeters are both used to measure altitude, but they work in slightly different ways.
Radio altimeters use radio waves to measure the distance between the aircraft and the ground. They are accurate to within a few feet.
Radar altimeters use radar to measure the distance between the aircraft and the ground. They are accurate to within a few inches.
The main difference between radio and radar altimeters is that radar altimeters can measure altitude through clouds and other obstacles, whereas radio altimeters can only measure altitude when there is a clear line of sight between the aircraft and the ground.
