Hi Truefaith,
Slasher has posted a splendid picture of a pair of governor bob weights. As you can imagine, if they were rotated more quickly (rpm increase), they would move out. If the rpm decreased, they would move back in.
I'd have gone for D - twice.
Q16. If engine power is increased with propeller lever in the constant speed range rpm increase, then:
(a) Governor weights move out, blade angle decrease, rpm decrease, weights remain
(b) Governor weights move in, blade angle increase, rpm decrease, weights move out
(c) Governor weights move out, blade angle increase, rpm decrease, weights move in
(d) Governor weights move out, blade angle increase, rpm decrease, weights move in, blade angle decrease again
Not sure is it correct? I chose (c)
Edit Thanks BOAC, I agree, E is probably better
