Has anyone today said what a total POS DeltaNet is! I can log in, but every link I click just logs me back out. Usually that is a short term deal, but today I can't do ANYTHING related to DeltaNet.

The AWCAS was unstable (receiver's fault) and the boom operator initiated the contact when the receiver was unstable (tanker's fault). It looks like there was either an inner or upper limit disconnect (compressing the boom). However, after the disconnect, notice the AWCAS moves downward (too fast actually). This causes a low pressure between the airplanes. The tanker's autopilot senses that low pressure and assumes a climb (higher pressure down low, lower pressures up high) and starts trimming to counteract those forces. But the trim rate cannot keep up with what the autopilot is sensing and the autopilot abruptly disconnects. This causes an immediate nose down pitch change caused by the now out of trim tanker (remember the autopilot thought it was climbing due to the low pressure and was trimming nose down). The tanker then quickly dives into the receiver until the pilots can react. And as such, the receiver gets a very close and uncomfortable view of the tanker's tail. The KC-135 is very susceptible to this -- the KC-10 is not. Any large receiver moving up or down too fast most likely will cause the KC-135 autopilot to kick off. I have had it happen at night while in the weather. I was flying a KC-10 receiving gas from a KC-135. I could have sworn my co-pilot had yanked the controls and pitched us up into the tanker when in reality, it was the tanker coming down towards us. It was one of the more scarier moments I've experienced in flight.

I haven't had any problems today. You on the road or at home?

There's an expanded & updated set of LCA meeting notes on the DALPA Forums. Good stuff.

I haven't been logged out today, but Deltanet and especially Icrew has been painfully slow for myself and at least one other person the past week or two.

The only time the AP kicked off for me was when a KC-10 underran us. If you don't get under the tail, the AP can keep up. Stop getting under us, you're no chick, even though you take the boom. Cept a KC-10 gives and receives, I guess that speaks for itself.

I'm not going to argue because we're friends. hahaha ... but I have seen the autopilot come off without under running the tanker. I shudder to think what would have happened had we under ran the tanker and that autopilot came off. That would not have had a good outcome.

Can someone please post some of the pictures that got Jesse in trouble? I don't want to repeat his mistakes.
