The Ravenscar Profile is appropriate for hard real-time systems, in
and of itself, but it is especially appropriate for systems that
involve the kinds of analyses required for high-integrity
applications.  As a subset of the language intended for
safety-critical applications it is not necessarily optimal for more
general real-time designs, although the restrictions it imposes are
reasonable for small footprint, high performance, hard real-time
systems.

Don't get me wrong -- I'm an advocate of Ravenscar -- I'm just saying
that Ravenscar is not the sum and total of Ada's real-time
capabilities.  Since the OP was asking in the most general sense I
thought it best to provide a more precise description of Ravenscar's
domain.
