Undercarriage doors
« on: April 28, 2012, 08:10:22 PM »
Just noticed on the video of Thursdays flight that the undercarriage doors seemed not to come up in sync with each other.

Is this normal ?

In actual fact it's better than it has ever been @ least the legs are all moving together now.

There is so much pipework and so many sequence valves involved in the retraction plus 7 microswitches on each of the mainlegs and 9 microswitches on the nose leg.  Even though the pressure is equal throughout the system it will never all operate at the same time. As long as all three legs go up within the allotted time all is good.

Ta. Having cleaned some of those pipes on Wednesday I suppose it was a dumb question :-)
