Prior to Dan's comprehensive posting, I tried finding an online copy of the T10 Pilot's Notes to refresh my memory on the standard spin entry. Dan confirmed what I remembered - 50 kts, full rudder, stick back and neutral ailerons.
I had no luck with the T10 notes (well, not a free copy!) but I did find a copy of the DH Pilot's Manual for the civil Chippies (Mks. 20, 21, 22 and 22A) (
http://is.gd/fyBII ). The recommended spin-entry includes the use of ailerons:
The aeroplane is difficult to spin properly at almost all centre of gravity positions. Therefore it is usually necessary to apply ailerons against the intended direction of spin, in addition to the normal pro-spin control movements. Entry with central aileron will probably cause the aeroplane to describe a semi-stalled spiral dive. This is often confused with a true spin
I find this very surprising. I did spins in two civil Chippies prior to my time with UBAS and in those we did the aileron-neutral entry, just like in the T10, with no problem entering a true spin. Is there something different about the civil versions or were DH just being very cautious? I don't ever remember getting into a spiral dive instead of a spin.
Beagle, I hadn't heard that solo-spinning was banned. Did you find out what happened to trigger that?
