Gear down all the way – blimey!
I once had to ferry a Dan 1-11 from Toulouse to LGW with the gear down. Tech log entry cleared for one flight only no pax.
I FILLED it up with fuel (5oo series ) and set off. It was soon obvious that the burn was not conforming to the ops manual burn with gear down.
The upshot was that I arrived at LGW on fumes, and a very tight bit of me, in a place best not mentioned. It would be interesting to know how much that 737 burned on the ferry mentioned above.
