What type of information can be accessed via TEL-TWEB?

TEL-TWEB, or Telephone Terminal Weather Broadcast, is a service that provides pilots and other aviation personnel with access to up-to-date weather forecasts through a telephone system. This service is specifically designed to deliver tailored weather information that may be crucial during flight planning and operations. When a user calls the TEL-TWEB service, they receive current weather updates and forecasts, which are vital for ensuring safe flight operations.

By contrast, while real-time radar images can certainly enhance situational awareness, they are typically accessed via other platforms, such as aviation weather websites or mobile applications. Historical weather data reports and air traffic alerts serve different functions and are not the primary purpose of TEL-TWEB. Thus, the choice of accessing telephone-based forecasts aligns directly with the operation of TEL-TWEB, making it the correct answer in this context.
