How do planes know not to crash into each other?
Almost all modern large aircraft are fitted with a traffic collision avoidance system (TCAS), which is designed to try to prevent mid-air collisions. The system, based on the signals from aircraft transponders, alerts pilots if a potential collision with another aircraft is imminent.
Do airplanes have GPS tracking?
Can’t planes be tracked with GPS? Yes, but while GPS (Global Positioning System) is a staple of modern life, the world’s air traffic control network is still almost entirely radar-based. Aircraft use GPS to show pilots their position on a map, but this data is not usually shared with air traffic control.
How do military aircraft communicate with each other?
Military aircraft tend to use UHF for communications, both with the ground and each other. There are datalink systems such as ACARS (Aircraft Communications Addressing and Reporting System) which can pass data between ground stations and the aircraft. The pilot can read and respond to these messages via a screen on the flight deck.
Can other planes hear what the pilot is talking to you?
Obviously the crews of any other aircraft in the area can hear what they are saying, along with ATC, so in busy traffic areas anything other than short business-related messages are disapproved of. They could take a chat to another frequency but then they’re not monitoring the original one, which is unsafe.
How do airplanes communicate with air traffic control?
A: Modern airplanes use satellite communication to talk with air-traffic control. There is an older technology, High Frequency Radio, that can be used, but it is not as reliable. Q: Is radio/controller access limited during trans-Atlantic flight?
How do airplanes fly over the ocean?
A: Flights over the ocean (or remote parts of the jungle) are separated by time and altitude. When flying over specific latitude/longitude points, the pilots report their position to air-traffic control. The controllers know the estimated time of other airplanes in the area to the same point in the sky.
