Before the plane didn't have satellite navigation, how could it fly to its destination?
In the era when the earliest passenger planes just entered passenger transport, there are two kinds of aircraft navigation:
The first one is for later use, and it is more accurate to rely on a navigation platform called vor/ndb. Vor navigation platform calculates the orientation of the aircraft, that is, the magnetic heading of the aircraft to the navigation platform, and the heading of the aircraft can be known through angle calculation. The NDB navigation platform calculates the average of the two signals sent by the plane and calculates his position, so that he can know where he is. On the plane, the pointer on the plane instrument will point in the direction of VOR navigation platform. Guide him to this navigation station (each navigation station has its own single frequency, for example: 104.30). There are two such instruments on the plane. When one is working, the pilot will set up the next vor navigation station to guide the next prescription slot and use it in turn to reach the destination.
The second is the radio VHF omni-directional beacon, which consists of two sets of navigation. One will emit a unique Morse code, and it will emit a corresponding beep on the plane (such as beep-beep-beep-beep-beep-beep-beep). There is a notebook on the plane. If the bands are the same, it means that this navigation station has been found.
That's basically all, thank you!
