I also do not have access to an S-76A Flight Manual, but I know there is one S-76A Category A VTOL procedure that is actually certified by an Airworthiness Authority. The operating weights are given in Supplement 3 to the CAA Approved S-76A Flight Manual. The takeoff uses a vertical climb to a 120 ft TDP. But because vertical landback from 120 ft is not possible, the rejected takeoff must be performed with forward speed, so there is an associated rejected takeoff area (possibly 400-500 ft?). I think it’s called a Vertical Procedure, but it’s actually a Short Field Procedure. Don’t know how to get a copy of Supplement 3; perhaps Nick Lappos (who started this thread) can help.
