Yes, authorised and used and for the US cleared on all UAARSI equipped -135 variants too. We (the UK) did not clear it for UK RJ as part of the initial RTS (this may have changed now), but the USAF clearance remained in place. The details of what pumps can be used and the rest of the procedures are all in the aircrew manual.
