  1. You should take a gander at a few of the patents the Navy has filed lately. Perhaps complete BS, and perhaps it explains some of what is being seen. It does not explain how the navy acquired the tech.
  2. At least they’ve got iPad holders these days and may not be navigating with a hiking GPS.
  3. All cured by the two switches that turn off the bulbous bow actuators.
  4. Less drag and they are often designed to create a wake that cancels the ship’s wake.
  5. For the record it’s a Kia and a Honda at our house. So fuck Hyundai. And commie pinkos from the people’s republic of California too.
  6. What if they’re just applying anal swabs to test for some kind of interstellar Covid equivalent?
  7. If we’re out of the lane by so much as a boat length! You’re relieved. Right full rudder, reverse starboard engine! Sound collision. -or- Sand dune! Right ahead!
  8. I flew a Beech 99 (several actually) that probably had more hours than any two posters here combined, and can only vaguely recall turning the gen off for start after recharging the battery. There was a test we did each Friday where we checked to see that some very important. 150A circuit breaker hadn’t popped in the previous 7 days. And the fire detection was IR so sunlight hitting the nacelles just so would give you a fire warning.
  9. You might just need a fresh set of eyes or a new voice delivering the same message.
  10. We had a discussion the other day about how screwed we be for a while if we had to fly a plane that didn’t auto trim itself or leave the pitch and bank wherever you set it in perpetuity.
  11. Btw, the high wind condition limited DFW to arrivals and departures on 31L/R. Winds were almost directly out of the West at 30-40 knots. One ATIS had them at 38 gusting to 43. Anyway, here’s a nice pic of the lineup to depart 31L. Zoom in to see all the dinosaurs being sacrificed to cross wind limitations :
  12. I’m sure the Austin City Council ran low on BS or something. Here’s one pooping out Blackhawks in PBI:
  13. Everything this guy said. Lubbock Aero or Chaparral were the two FBO’s in use back in the day. There’s a short North/South runway directly across from Chaparral that might be used for your short takeoff and landing stuff. Some airline service, but overall not really busy.
  14. Somewhere an Aggot engineer just had an idea about how to squeeze more seats minus a view into Kyle Field.
  15. Still dislike the party decks. Not the idea necessarily, but the placement is less than ideal.
  16. Given its state at destruction I’d say very few. I’m sure most had other jobs that took longer than expected and that their communicators mysteriously stopped being able to contact their client to inform them.
  17. I hadn’t really read up much on the engine other than the how it works. Didn’t realize PW1100G had a 12:1 bypass ratio. I remember when 6 or 7 to one was considered wild stuff.
  18. Chicago O’Hare is an interesting place. One of the busiest airports in the world, and the departure procedure is to fly a heading. That’s it. Oh, and ground doesn’t want to talk to you when taxiing in unless there’s a problem or you need to be sequenced or rerouted. Just follow be plane in front of you and contact ramp when u get close. Well you just taught me something. I wonder if that’s why the fan blades on the NEO’s are shaped the way they are. Best push versus drag dependent on blade speed and radius. They kinda narrow and then flare at the end. Maybe reduce transonic drag. *Well after doing some reading the tips of GTF’s are subsonic which reduced noise.
  19. Probably the same for anyone who’s seen the inside baseball on any company’s engine failure analysis. I know the geared Pratt’s were eating themselves at an alarming rate until recently where they’ve seemed to get the materials up to snuff for the technology.
  20. True, but the shape and what it implies will still be valid.
  21. Scalloping seems to make sense, and yet Airbus won’t do it because they think they can do some kind of sound baffling that has the same effect without the performance hit. I can say the new geared turbofans are crazy quiet, and they even mostly hold together these days. Still have to turn the ATHR off and manually sync them at times.
  22. Big fans make that sound. I don’t know why. One of the motors types on the 11 is the CF6 or TF39, and is known as a bit of a screamer on the C5’s that haven’t been updated to CFM Super Galaxies. I know FedEx has them on their 11’s, UPS has the Pratt’s, and I don’t know if they mix their engine types in fleer (some being Pratt and others being CF6). Usually not, but the 11 was built in limited quantities, and they may have laid their hands on them wherever they could for cargo conversion. Completely spitballing, but he may be hearing that.
  23. Complete guess, but big motors move more air and large wings and lifting surfaces create more wind noise. Having said that, 777 motors are moving twice the air as an MD-11. It’s probably just the acoustics of your location, something to do with the bypass ratio (low speed, quieter fan air to high speed, louder, jet exhaust) and the natural sound signature of the motors involved. The motors powering the 11 have been around since the late 70’s to early 80’s and power A300 series, 747s, 767s, MD10/11s, C5s and the core is used on some 777s. All that to say that they probably meet all noise limit requirements, and are just louder than other motor types on smaller planes. They’re still loads quieter than the original turbojets or low bypass fans.
  24. It conveniently resembles the female reproductive system so that eventuality is covered.
