Landing gear message

[Christopher Low 5,353]

A message that I have not seen before appeared just after take off this morning in the 747-400F. I had just raised the landing gear (and moved the gear lever down to the central position) when the message "GEAR DOWN DISAGREE" appeared on the EICAS screen. I cycled the landing gear down and then back up again, and the message vanished. Does this appear if I have done something wrong, or is it just a rare "glitch" that is programmed to occur once in a blue moon?

Did you wait for the gears to go up, ie no GEAR in transit icon in the upper EICAS before moving the lever to off position?

That is probably the reason for the message, Chris. I had a feeling at the time that I had been too quick moving the lever to the OFF position.

AFAIK the typical procedure is to raise the flaps on schedule and with flaps 1 or flaps up you'd turn off the landing gear.. Then this can't happen 😄

Typically the gear handle is centered with the first movement of the flap handle, which should be more than enough time for the gear to retract and the doors to close.

I've had it happen before if I was trying to get the plane up in the air quickly for some reason, whether I was testing something or trying to get set up for a screenshot, so I didn't do a full-fledged setup, if I tried to raise the gear too soon whilst the gear was still on the runway, I'd eventually get the message. Look out in spot view, and sure enough, the gear hadn't even moved.
