During instructors course training on the Tiger Moth phase at RAAF Central Flying School at East Sale, we were taught how to re-start a stopped prop by diving.
On one particular trip the diving failed to rotate the prop. The instructor calmly told the student (himself an experienced pilot) to patter the subsequent dead stick landing (real one) and after the successful forced landing which was on West Sale aerodrome, ticked the students progress sheet as sequence completed.
Interestingly, there was no requirement to enter anything into the EE77 (maintenance release) since Tiger Moth prop stopping during aerobatics was quite common and not considered a defect.
