Shackman,
In the aircraft you had the SAS runaway....how would you describe the SAS system on yours to an American equivalent Model of the Chinook?
I am familiar with the US A, B, C-, and C models but not the D or later models and certainly not the many RAF versions.
On the three models I flew....there was a single Red Guarded Switch that turned the SAS ON and OFF. The C- and C model had the same plus a PSAS system for Pitch Attitude Hold.
On the machines I flew a quick flip of the Red Guard and Toggle With....and in theory the SAS links would have reentered or at least stayed where they were.
On some steepish slopes I have had some Droop Stop Pounding but never any damage.
I have had the unique thrill to hear them really clattering while in flight in the A Model when in a weak moment I turned the SAS off on a Student in a steepish turn and the aircraft got away from him and tried to swap ends at a hundred knots IAS....again no damage.
I can imagine yours was an experience that you will not forget....and I am very glad it was you and not me that got that thrill!
We were still learning about them when I started out on them....and flew some with single digit build numbers for the A Models.
The kind with the fixed aft gear with double wheels and had to be ground taxied using the Aft Gear and flight controls only.
