Re: Never again on PE - share your mistakes

This story has enough "meat" on it that it deserves a structure, so I'll give it the full treatment:
Dedication: To the controller who put up with me throughout the entire flight, along with my profound apologies for putting him through it.
Prologue
I decided to make the jump from simple aircraft like the C182 Skylane and C337 SkyMaster, and try my hand at larger, more complex airplanes. I've read a lot about the PMDG 737NGX, but it looked like more of a quantum jump rather than a little jump. So, I tried out the FSX stock CRJ700. I flew it a few times offline just to get a feel for handling it and to get familiar with the autopilot and GPS. After I got the technical problems solved, I decided to start with something I'd done before, so I flight planned KLAS to KLAX, with the BOACH5 departure, HECTOR transition, RIIVR2 arrival, and RWY 24R ILS approach. I filed the flight plan, logged onto PE, got my clearances, took off and flew the route. It went smoothly until I was on the ILS approach and couldn't get the auto pilot to capture the GS, but I flew the approach by hand and landed safely. I then went offline and just flew a couple of traffic patterns, departing, flying east, then reversing and flying the 24R ILS approach, successfully using the AP to capture the GS and make the initial approach using the APPROACH mode. No problems, so I taxied back to gate 77, and decided to fly a longer flight-- KLAX to KSFO. And that's when the real trouble started.
Departure from KLAX
After filing my flight plan-- VTU5 Departure, RZS transition, BSR2 arrival-- I got my IFR clearance, taxied to RWY 25R, and headed for the wild blue yonder. I had the AP set for an initial altitude of 5,000 and the heading bug set for 250-degrees. After takeoff, I used the AP to climb to about 500 feet, then engaged the NAV mode to fly the departure procedure. For some reason, the plane pitched up like a fighter jet and rapidly gained altitude. I disengaged the AP, forced the nose down, and hand flew the plane to a position where I could rejoin the VTU5 departure, held my breath and re-engaged NAV mode... this time, the AP captured properly, and all went fairly normal for the next 30 minutes or so. The controller asked about my rapid climb and I admitted that I didn't know what happened, but after that departure, I was not looking forward to the approach at KSFO. He joked that he would give me a 30 mile final, and I quipped that 30 miles might not be enough. This turned out to be prophetic!
Arrival
While I was on the BSR2 arrival at 20,000 MSL, the controller instructed me to "cross Boulder at and maintain 10,000." I acknowledged, then glanced at the moving map (Aivlasoft) display, where I saw "Boulder" adjacent to a VOR symbol. I dialed in the frequency of the VOR, dialed in the course to take me to it, then switched from GPS mode to LOC mode. I mistakenly thought the controller had given me a deviation from the BSR2 arrival... I wish I had asked. I also wish I had done more than just glance at the map... if so, I might have realized that the controller was referring to "BOLDR" which is a FIX... not a VOR! In a few miles, he asked if I was off course, and I responded that I was proceeding direct to Boulder as instructed. He corrected my misunderstanding and assisted me in getting back on course, while I concentrated on wiping the egg off my face so I could see! I wish I could say that was the end of the story, but alas...
Approach to 28R
Approaching the San Francisco Bay around Menlo park, I was cleared for the visual approach to 28R. I had already programed in the localizer for 28R, so I used the NAV mode to intercept the RWY heading, while manually trying to slow the airplane, get the gear down, and descend to the proper altitude (these "complex" airplanes are called that for a reason-- it's just not like flying a C182!) so that I could fly the approach. Accomplishing this, I disengaged the AP and began my approach. All went well (okay, tolerable) until I was about 1 mile out at an altitude of around 500 feet. At that point, the plane began to slow and I got a stall warning. I quickly looked and saw that the airspeed had dropped to about 100 kts. I went to full power and waited for some airspeed... which never came. And before I could call the tower, I was in the Bay! I called the controller and told him I was going to have to paddle the rest of the way in. He asked me to stop at the 28R threshold to do a little fishing, and maybe cut the grass while I was there! The plane floated onto the runway, I got the instruction to exit right when able. By now, both the controller and myself were laughing so hard we could hardly talk. I couldn't resist addressing the main cabin with "please remain seated while I taxi what's left of our CRJ to the gate. If this and/or the laughing was a distraction, I apologize. I must have bumped my head on the yoke when we landed in the Bay.
Epilogue
I spent the next 3 days trying to figure out what happened... offline, I might add. As to the problems on departure, I still have no idea what happened. I've flown it a half dozen times since then, and each time has been normal. I think I did the same thing each time, but you know how that goes! The arrival mistake was obvious. I can claim that the chart was unfamiliar, the GPS was not what I'm accustomed to, the airplane was to unfamiliar... but what it really comes down to is twofold: (1) I should have been better briefed on the route-- there's just no excuse for that, and (2) I should have asked for clarification when I got what I (wrongly) thought was a deviation from the arrival procedure. The real humdinger was the landing in the Bay. I won't go into the 4 offline flights I attempted in the days following that all ended about halfway to KSFO when the simulator CTD'd (Crashed To Desktop). On the fifth attempt, I was just approaching the Bay at MENLO when, once again, the plane decelerated, lost altitude, stalled and crashed. On the sixth attempt, two days later, I successfully flew the entire route, landed, and taxied off 28R. As I did, both Left and Right generators failed... I looked, and all fuel tanks were empty!
I thought, that's not possible... the flight is 350 miles, and this thing has a 1700 mile range! Then the lightbulb came on... I reset the flight for KLAX gate 77 and noted that the tanks were less than 1/4 full... The short version is that when I "saved" the flight at KLAX gate 77, I had flown the plane from KSNA to KSAN, KSAN to KLAS, KLAS to KSNA, KSNA to KLAS, and finally, KLAS to KLAX... at which time I parked and saved the flight. What I didn't know was that each time I loaded the saved flight, the tanks were not restored to "full" status, but were instead reset to what they had in them when the flight was saved. So, for the final time, egg has landed all over my face. I have, so far, only concentrated on "flying" the CRJ, rather than learning all about its systems. I intend to correct this oversight...
So, now you're probably thinking to yourselves, "how could he be so dumb." That's okay, because I'm thinking exactly the same thing: How could I have been so dumb. So just take this little anecdote as an example of the therapeutic benefit of being able to laugh at yourself... It makes for a much more pleasant life... and with one final apology to my controller, I'll sign off!
