Why would a helicopter not show up on Flightradar24?
If an aircraft you are looking for is not visible on Flightradar24 it either does not have a compatible transponder or it's out of Flightradar24 coverage.

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.
There are a few reasons why your aircraft may not be shown. First, the aircraft may not be fitted with an ADS-B transponder, meaning it is not compatible with our receiver network. Second, if the aircraft is fitted with a Mode S transponder and not visible, it may be flying in areas with little or no MLAT coverage.
Why are some flights blocked on Radarbox? Radarbox allows some free searches and allows you to build your own widget to be able to track live flights. To protect the operational security of military operations, as well as the privacy of certain private jet operators, Radarbox either blocks or censors their tracking.
Where are the military planes on Flightradar24? FR24 filters out most of them, although recently I've noticed that a few get through. There are other similar sites such as adsbexchange that show them. Any airplane using ADS-B will show up on Flt Radar24.
Aircraft visible on Flightradar24 (within MLAT, radar, or Flarm coverage) In regions with MLAT, radar, or Flarm coverage most of the air traffic is tracked and visible independent of aircraft type. That includes propeller aircraft, helicopters and gliders.
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.
FlightRadar gives detailed information about all flights in the near future and the past while Plane Finder shows flights which have departed and are in the air. You can't see flights in the future. A point for FlightRadar. Plane Finder allows you to set multiple Filters at once, FlightRadar doesn't.
Air Traffic PatternTo sustain a safe separation from airplanes, air traffic controllers usually direct helicopters to fly lower than airplanes and move along a traffic pattern that is opposite to that of the airplanes.
The position is calculated based on many different parameters and in most cases it's quite accurate, but for long flights the position can in worst cases be up to about 100 km (55 miles) off. In settings there is an option to set for how long time you want to see estimated aircraft on map.
If a crew resets their transponder to the emergency code of 7700 (squawking 7700), all air traffic control facilities in the area are immediately alerted that the aircraft has an emergency situation.
Blue: Aircraft displayed as blue icons are currently being tracked via satellite. Satellites are collecting the ADS-B signals from aircraft and transmitting them to the Flightradar24 network. Space-based ADS-B tracking will be used to supplement our terrestrial receiver network.
Restricted aircraftOperators of private or sensitive aircraft may request their tracking details be restricted or not displayed. Generally, aircraft requesting that they not be displayed on Flightradar24 are military aircraft. Some military aircraft, such as various transport aircraft, are visible.
You won't find the Eagle on standard aircraft tracking websites – most of these services block radar data for certain aircraft by request – but it's possible to track all three aircraft that make up the Eagle fleet on ADS-B Exchange, a tracking website based on satellite navigation data.
This was because airlines had to operate at least 80% of their allocated airport slots, or else risk loosing them. They're incredibly expensive and highly sought-after, so airlines were left with no choice but to operate these empty aircraft (ghost flights).
The No Fly List, maintained by the United States federal government's Terrorist Screening Center (TSC), is one of several lists included in algorithmic rulesets used by government agencies and airlines to decide who to allow to board airline flights.
