Can a helicopter fly under radar?
Can a helicopter fly under radar? Any aircraft can fly under the radar assuming it is ground-based and the terrain allows masking. However, at some point, you will be discovered. Even the “low observable” fighters can be detected at some range, but by then the radars should have gone off-line.
Why do planes look slow when landing?
The airplanes appear to fly slower because we perceive angular velocity when we look at them or for that matter from them. Because they fly quite high you observe them from quite a distance. Further there are no other stationary objects close by with whom you could compare their speed.

Why do helicopters not show up on FlightRadar24?
FlightRadar and similar websites use several sources for aircraft detection, most commonly they use ADS-B. Not all General Aviation aircraft, to which helicopters would count normally, are equipped with transponders that are capable of emitting ADS-B data.
Can pilots see other planes on radar?
It's important to note that pilots do not see other planes on radar directly. Instead, air traffic controllers use radar to track the location and altitude of planes in their airspace, and then communicate this information to pilots through their cockpit instruments and radios.
Does Flightradar24 show military aircraft?
Websites such as ADSBExchange.com, FlightRadar24.com and FlightAware.com aggregate flight data in the United States and abroad using a mix of commercial and citizen-owned sensors that capture the movements of commercial, civilian and military aircraft in real time, 24 hours a day.
What happens when a plane is red on Flightradar24?
Red: When an aircraft is displayed as red that means that you are currently following that specific aircraft on the map or that an emergency squawk is on for this aircraft.
Why do planes fly low to avoid radar?
LOW FLYING AIRCRAFT CANNOT BE DETECTED BY STANDARD RADAR BECAUSE OF INTERFERENCE FROM CLUTTER. LOW FLYING AIRCRAFT CANNOT BE DETECTED BY STANDARD RADAR BECAUSE OF INTERFERENCE FROM CLUTTER.
Why can pilots turn off radar?
— The device could have an electrical short or catch on fire. Pilots would want to shut it down rather than risk a fire spreading to the rest of the cockpit or airplane.
Why do some military aircraft show up on Flightradar24?
Military aircraft in particular are exempt from many civil rules and regulations which would see most aircraft having an active transponder and of course their operational requirements will dictate they often do. That said, ultimately, any plane CAN disable it if they wish.
What does squawk 7500 mean?
The first emergency code that you may have become familiar with is Squawk 7500. This code is used to indicate that the aircraft has been hijacked, and therefore requires urgent emergency support from both security services and air traffic control.
What does it mean when an aircraft is squawking 7700?
A Squawk 7700 indicates an emergency. This can be an emergency of any kind. Pilots may input it into the transponder themselves – or when instructed to do so by ATC. As a result, ground control will know that the aircraft is dealing with a serious issue and needs help.
Is it possible to fly under the radar?
Yes. That's why some airplanes have terrain following radar. The same way you can fly in the shadow of the Sun early in the morning.
What does red 7700 mean on Flightradar24?
