"""I've done gear down ferries, although I don't think they're approved (in UK) with passengers aboard. As for having the pins in, that's a no-no. What happens if an engine fails? Better to raise the gear and maybe not be able to lower it again than crash off the end of the runway because of lack of climb performance."""
I've signed many an aircraft off for a gear down ferry back to main base and we always put the pins in, not only that they are wire locked in and flag removed, that's what the manuals say so where the "no-no" bit comes from i'm not sure.
Thats on 145's 146's and Dash's BTW.
