This is for a Model 500B specifically, but I assume the scenario covers other Models. After landing, with indication that all three gears are down-and-locked, the right-hand gear retracts. It seems fairly 'common' that this is usually because the PiC has selected the gear-up switch instead of the flaps-up switch. If so, is it the right-hand gear that actuates first? Presumably, if the PiC realises his error in time, he can prevent the left-hand gear actuating?

I'm following a rabbit's warren that leads me to believe that the hydraulic pumps at idle can't pump enough volume at idle to pull both legs over center simultaneously and that there is something about the right leg (placement of the cylinder?) that makes the right leg easier to pull over center than the left leg. Once it comes over center, the resistance is a lot lower on the right side, so the left leg won't come over center until the right leg fully retracts. -----Original Message----- From: owner-commander-list-server@matronics.com on behalf of Barry Collman Sent: Tue 8/28/2007 7:50 AM Subject: Commander-List: Main gear [bcc][faked-from][html-rem] Hi All, Can I just check something with you all.

That being said, I've heard of gear retracts happening on the ground. I'm certain that ONE engine by itself makes enough pressure to retract the gear at idle, as even during warmup at low RPM, my hydraulic system is steady at 1,000 PSI regardless of steering or flap actuation. As far as right vs. left, I don't know the answer to that one... /J Brock Lorber wrote: > This is puzzle that is going to have an interesting answer.

The Google Earth imagery are not conventional photos, but 'orthophotos'.

Lots of other stuff gets done to the images..... I'm actually processing an orthophoto right now at work. (I'm hard at work, honest.) The ortho images have a lot of blending and processing done to them to have them look any good across seams, and to correct for vignetting and uneven tone across them. Its quite a trick to get all these images to look any good all stuck together at once.

God bless, Andrew ________________________________ Message 14 ____________________________________ Time: 05:23:46 PM PST US From: "nico css" Subject: RE: Commander-List: Weird 747 shadow Hi Andrew. I don't think so, because the 747 would have to have drifted south without any forward movement. The shadows of the surrounding structures indicate that it's early morning, so in that respect the blue shadow is in the right place. What is a bit off, I would say, is that the shadow indicates that the sun is slightly south of the 747, which is impossible seeing that Johannesburg is 26 deg south and the sun never gets further south than 23.5 deg. However, if the shadow was moved due to manipulation of the satellite photographs, then it might not show where it actually was. Steve gave an excellent explanation: satellite photos are not regular photos but orthophotos, which are programmatically manipulated to make the individual satellite images fit seamlessly in one image, and perhaps some shift could have changed the color of the shadow. Steve I apologize if my paraphrasing what you said has lost the message. Who knows, but it is very interesting.

Talk about opening my yap before I have all the info :-) Found some other aircraft with ghosted shadows. No I didn't scan Google Earth ... well I did look at O'Hare to see if there were any on approach/climbout, and at Vancouver, Toronto, Calgary, and ... but then I gave up and cheated by looking at http://www.gearthhacks.com/dlcat24/Aircraft-in-flight.htm Steve, given this, is it not possible that two photos are taken and then overlaid to give the 3D effect when one tilts the earth to a more horizontal plane? (pun unintended) This would explain the aircraft "moving on". In each of the ghosted shadows the ghost aircraft appears to be on (or slightly higher) than the clear aircraft. However, on a slower aircraft (like the helicopter, or aircraft on finals) there isn't any ghosting.This would add to the theory that the aircraft has moved on - only fast aircraft appear to be ghosted.
