  1. That was my first thought, 6000lbs cargo capacity is hard to do under 12,500. It sounds more like an ATR replacement. The 400 series Otter has a MTOW of 12,500 and an empty weight of 6881, for a capacity of 5619. Even the 50 year old 100 series Otter has a 5,716 capacity. I bet that with advances in materials over the last five decades, they can get a 6000 lb capacity in a 12,500 lb plane. Seems worth it to save on an extra pilot. https://www.vikingair.com/twin-otter-information/technical-description A full fuel load weighs almost 2600 lb. The payload for a 100 nm range is 4061 lb. We should be glad that planes to replace the caravan are in the works. With more available on the market, it should drive down costs for a DZ. Is there a thread about wishing that 20 years ago there were a bunch of single engine turboprop, high wing, tailgate aircraft that could take 12-16 people at a time.

  3. The patient: 2008 Volvo S60 2.5T (turbo inline 5 cylinder) 95k miles My dealer said that the throttle body should be cleaned after starting a job to replace the mass airflow sensor, saying that it is dirty and will contribute greatly to the early failure of the replacement sensor. It doesn't seem that the condition of the throttle body could be related to the sensor, as the sensor is upstream of the throttle body. So, what do you think?

  4. I think that kind of rating also assumes a fuel load much higher than would be required of a jump operation, so more of the total weight can be jumpers and still comply with operational limits.

  5. A perfect student/first AFF jump allows the instructors to attribute it to their instruction. No slight intended.

  7. The turbo Otter would be a more practical choice. Maybe not a lot of single otters are still around? Or maybe there are some with the original piston engines gathering dust, awaiting conversion? The high horizontal stabilizer is nice, but of course the taildragger configuration is troublesome for insurance cost and pilot skill required. https://www.airinuit.com/en/fleet/de-havilland-turbo-otter-dhc-3 People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired.

  8. It is a part of the overall subject, having the boundary layer stay "attached" to keep it generating more lift until the critical angle/angle of attack when it doesn't stay attached which is when the wing is considered to have stalled.

  9. I think that using non-zero porosity fabric on the lower skin does not result in lower performance over time. When a wing is flying at high angles of attack (such as during a flared landing), it is very important that the airflow over the top of the wing stay "attached"/not separate from the surface of the wing. If air is leaking out through the top skin fabric too much, then I think it has the effect of separating the airflow. Conditions on the bottom skin of the wing are very different, with separation not being an issue, so leakage through non-ZP fabric on the bottom doesn't matter. If it was possible to actually suck air into the wing through/from the top skin, then you get the ability to produce good lift at even higher angles of attack, as the airflow stays attached when it otherwise would not. This has been done on some experimental airplanes, including a Boeing 757 testbed that had part of the wing drilled with very tiny holes and a vacuum applied to suck air into the wing. So, air leaking out through the fabric matters a lot for the top skin, but not for the bottom, as long as it is not so much that cell pressurization suffers. That's my theory on why non zp is being applied on bottom skins, and I think it makes sense. In my previous life I was a mechanical design engineer, even did such for the Boeing company.

  10. If you need 2 wraps to be able to stall it, I'd think you needed to shorten it by more than 2 in. Gotta analyze it properly. About 3-4 in shorter was needed for mine. Grabbing the top of the toggle instead of inside the loop (bottom of the toggle) allows for more total stroke length and made a big difference on my Pilot 210 People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired.

  12. I recall a news item on that helmet about a month or so ago on NBC News. At that time IIRC is was a 'one & done.' Jerry Baumchen If what was being discussed was a motorcycle helmet, that would be reasonable. For a football helmet, that doesn't seem likely.

  13. Be careful, as daisy chains can get locked up more easily than you might think. I learned that when I used daisy chains to shorten the long bridle on my old parafoil that had a long pilot chute controlled reefing bridle. It locked up and would not go through the grommet on the canopy. People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired.

  14. I think the design is lousy, but it does bring up an issue worth discussing - the desire to have the pin stay put until we want it to move. Main closing pins usually behave, but not always. A curved pin could have a similar design as this coffin nail, or there can be other ways, perhaps thought of "external" to the pin that can improve pin security. What matters is properly identifying that there is in fact a problem worth fixing, and how to improve it without causing other problems.

  15. I never turn mine off, same batteries for over a year. People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired. I’m certainly not, and I’m sick and tired of being told that I am
  16. Did the guidelines change in the last several years? I did a 24k AGL jump at the '06 WFFC from Mullins. We had a proper mask system to use on the plane only. I would be surprised to find out we weren't doing things per guidelines/requirements.

  17. If you still have the original d-bag, then you can eliminate a possibility by going back to it. Even though you have been using the new bag for a long time, maybe something has changed about it and is allowing early dump of the canopy.

  18. I definitely noticed the ridiculous position with arms completely straight overhead and straight legs together. Very little roll stability with that position.

  19. A bag lock always calls for a cutaway. No controversy. A total malfunctions (can't find or pull the main) does not call for a cutaway. No/very little controversy. As you move past being a newb, it is OK to know that a PC in tow is where there is some controversy about whether cutting away first is best. Lots of threads that focus on this. Don't believe those that claim only one side of the argument has any advantages. Understand fully what is being claimed before deciding which side to come down on, or that a particular person's good result proves their position.

  20. I don't turn off my Optima, and get over a year for battery life. I also never turn off my Neptune II, same battery life. You get the confirmation that it has correctly identified ground level as you pass through 1000 feet. Both my visual and audible have always been right in sync with others.

  21. This is why I suggested closing your eyes and just flying by feel. People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired. I’m certainly not, and I’m sick and tired of being told that I am
  22. They have some value, I would guess 2-400 total. Go ahead and sell them in the classifieds. They aren't right for newbies to buy, but there will probably be somebody that wants them for appropriate use. You never know if for instance someone is trying to put a rig for water jumps together, this would be perfect, and getting it packed is on the person buying it to negotiate.

  23. Maybe try closing your eyes just before getting out. Just feel the wind and fly that. Keep eyes closed for several seconds. Of course it would be best if an instructor or someone appropriately experienced, or you makes sure that there is no conflict with other groups. I think it would be important to have a very positive image of how it will go.

  25. The residual value for the 2015 Civic LX 4-door is 11,800. I think this is an attractive price, and definitely less than they would advertise for such a model year civic after it went through their process. I also like the idea of knowing the history of the car, how it was treated, etc. People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired.
