It’s almost Spring Break, and many of us will be traveling by air. Maybe you will sleep during your flight, or maybe watch a movie. What you will not do is think of all the processes taking place in order for you to depart from State College and land at your destination. Hence, me telling you a bit more about the complexity of airplanes and the importance of technology in this field:
70 years ago, flying was considered extremely dangerous, as pilots navigated with the aid of visual landmarks, could not foresee inclement weather, could not communicate as easily by radio, etc. Nowadays, flying is considered to be the safest way to travel thanks to all the technology that has been implemented to reduce the workload of the pilots monitoring and flying the aircraft. A “Flight Management System” or FMS, is probably the best example of the introduction of advanced technology in this industry. An FMS will manage the flight plan proposed by the pilot with the use of inputs, such as waypoints, takeoff weight and amount of fuel. For example: after a pilot input the information, the FMS will tell which radio frequency to use in each stage of the flight, as well as the velocity required to safely takeoff.
IoT also plays an important role while in-flight, as “pitot” sensors outside the aircraft provide information about “True Airspeed” and “Angle of Attack”, which are basically fancy terms for velocity and pitch. Several emergencies have been prematurely detected due to the information provided by these sensors. However, these are not the only devices using IoT to keep an airplane in the sky. They range from fuel burn monitors to cabin pressure to weather detection. As Business Insider stated in the article “Why every flight you take is obsessively monitored”, IoT devices in planes can even help the National Weather Service “predict climate in a more precise way”, “as airlines like Southwest and UPS provide data directly from their planes”.
Finally, while approaching the destination, the FMS, in addition to other systems, will guide the plane down a safe route by using information from radars installed next to the runway to accurately predict the descent rate and an almost-perfect alignment with the center of the same runway, at which point a pilot will deactivate the auto-pilot and touch down.
Technology has made flying the safest way to travel. While some people might still be afraid to sit in a plane for hours and experience turbulence, there are many sensors monitoring the health of the engines, the cabin, the airspeed, the altitude, etc. In addition to many people constantly monitoring the flight path of the airplanes, making sure a safe distance is maintained and talking directly to the pilots in order to make changes if necessary. So don’t worry, you will definitely fly safely this Spring Break.
