But there are several problems inside the constraints.
1, the price is high.
Rescue helicopters will cost about 40,000 dollars for an hour. Not many can really afford it.
2, airspace application trouble.
Domestic low altitude flight is not easy. You have to declare it every time. The formalities process is long.
First aid is time-sensitive, and when the application comes down sometimes it can't be done.
3, aircraft supply points are few.
Helicopters need to refuel when flying hundreds of kilometers.
There are no supply points in many areas of the country, and helicopters don't have a place to stop and refuel.
There are also some details.
If you really want a helicopter first aid, you can ask the speedy helicopter 6s alliance.
There are professionals over there who can tell you if it can be done or not.
