Having an RTOS or not doesn't have much to do with Ada. You can write Ada programs for a bare board if you have an appropriate compiler. In that case, the embedded target compiler would come with a runtime library that did some of the work of an RTOS (scheduling, etc.) If you have an RTOS and an Ada compiler that targets the RTOS/board combination then, quite naturally, you can write hard realtime systems with it. If you have a non-RTOS on the hardware in question (Windows, for example) then there isn't anything that Ada or any other language can do for you to enable hard realtime development - unless you simply move the OS out of the way and write to the bare machine. In general, Ada has excellent features to support development of realtime and embedded applications. However, you must always keep in mind that not all compilers are created equal and you need to evaluate the available implementations to determine which is best for your application.
