This is quite interesting.  I was in a rather heated discussion in another
ng over the RATs.  It started with me questioning the use of a hydrazine
(very nasty stuff) powered APU in the F-16.  This ac also has a UPS
(Uninterruptable Power Source) which is used prior to starting the APU in
the event of engine failure.   Which I understand, powers up much faster
than a regular APU.  The main argument for having a hydrazine APU was due to
the unreliable power provided by a RAT.   That is a RAT does not provide
good 400HZ power for the ac systems.

I sounds to me like someone may have been spouting the gummint line on the
reliability of RATs and the power they produce.  Anyone have any comments.
