Yep.

If you have a trim tab, remember: "elevator disconnected - use trim
normally. elevator frozen - use trim backwards."
I haven't thought of a good mnemonic for this, however.

If you don't have a trim tab, never mind.

The pilot selected full nose down trim, in response to his limited pitch control.

This is off-topic, but... he did the exact opposite of what should
have been done, didn't he?
