Emergency landings and/or forced landings are stressful situations, but talking about meanings, are they the same, please?
Not all forced landings are emergencies, and not all emergencies are forced landings! (See below)
In general, the term "Emergency Landing" is a superset which covers a bunch of different scenarios where a landing is not quite to plan. Such as
- Forced landing due to mechanical failure. Note that a forced landing can absolutely be at an airfield. It can also be in a literal field.
- Precautionary landing, such as where continued flight is possible but inadvisable
- Ditching in a body of water
- Belly landing due to inoperable landing gear
A forced landing can also be one where the pilot is forced to land due to military interception, which is not always an emergency.
This is all covered in great detail here
The FAA also publish some useful information on this subject which repeats much of the above information, reproduced below for clarity
Types of Emergency Landings
The different types of emergency landings are defined as follows:
• Forced landing—an immediate landing, on or off an airport, necessitated by the inability to continue further flight. A typical example of which is an airplane forced down by engine failure.
• Precautionary landing—a premeditated landing, on or off an airport, when further flight is possible but inadvisable. Examples of conditions that may call for a precautionary landing include deteriorating weather, being lost, fuel shortage, and gradually developing engine trouble.
• Ditching—a forced or precautionary landing on water
