  1. At least in some airplanes, the avionics reset when engine is started. I assume they are not tolerant to surges/dips.
  2. Curious why no conditioners on avionics? Surely it can't be for cost reasons given how much these boxes go for.
  3. Perhaps regionals and commuter will benefit the most. Reading this report, I suspect no one would complain much if the single pilot is PNF : https://asrs.arc.nasa.gov/publications/directline/dl5_one.htm
  4. Reasonable progression. What you outlined are problem areas that can be solved. Whether an AI solution is the best one, that is a separate problem. Why again don't we have PDC everywhere?
  5. When you write an algorithm, you prescribed exactly what should happen. When you train a ML model, you don't prescribe what should happen. Instead, you state whether a specific answer is acceptable. Because you do not specify all acceptable answers, there's a chance that one that is not acceptable can be produced. Further, you do not know which answer will be generated. This analogy below might help: Case 1: you program way points in your navigator. Then you turn on the auto pilot. You can always tell when which way the A/P will turn. This is similar to writing an algorithm. Case 2: you tell your hanger neighbor that the hanger needs to be cleaned every Tuesday. On Tuesday, your neighbor flies out to a hamburger run. You give feedback that the flight was an acceptable solution. The Tuesday after, the neighbor parks their airplane in front of your hanger, blocking your flight. You did not anticipate this solution. Not only you don't understand why they picked this solution this time, but also you don't know which solution they will pick next. Hopefully that explains.
  6. That's double standard, no one complains when I make stupid, inexplicable decisions On a more serious note: I agree with that. I think well defined decision paths will be in use.
  7. Well, let's find out, shall we? This is the response from ChatGPT. Unreliable airspeed and warnings. Question: What would you do in the following scenario? You get unreliable airspeed indication. You simultaneously also get a stall and overspeed warning. Answer: As an AI language model, I don't have the physical ability to act in the real world, but I can provide some suggestions based on aviation safety protocols. If a pilot were to experience unreliable airspeed indication, a stall warning, and an overspeed warning simultaneously, it could indicate a potentially dangerous situation. Here are some recommended steps that a pilot should take in this scenario: Disconnect the autopilot to take manual control of the aircraft. Cross-check airspeed indications against other instruments such as the altimeter and vertical speed indicator. Attempt to confirm the actual airspeed of the aircraft by visually estimating the aircraft's speed and comparing it with the groundspeed. Adjust the pitch attitude of the aircraft to prevent a stall or overspeed condition, keeping in mind the possibility that the airspeed indication may be incorrect. Communicate the situation to air traffic control and consider diverting to the nearest suitable airport. It's important to remain calm and follow proper procedures in such a situation. Pilots are trained to handle these types of scenarios and have emergency procedures in place to ensure the safety of the aircraft and its passengers.
  8. Isn't AI an overkill for the task of flying an airplane? Unlike road environment, the airspace is not that complex to automate.
  9. In summary: * Improper techniques were used to control the airplane * These techniques are hazardous, but did not cause the accident * Accident caused by disorientation due to limited proficiency in IMC * Medication could be a factor * In terms of hours, the pilot was experienced So what lessons can we draw? 1. Proper training 2. Use of flight risk assessment.
  10. I thought the flying pattern implied it was the pilot based on similarities to previous flights . Assuming it was, I wonder why they would put themselves in a situation they know they can't handle. Maybe they were impaired? Maybe they did not anticipate the difficulty?
  11. But what could cause a pilot who is not confident with their skills to undertake a flight outside their skill level?
  12. Thanks. I wish I could say the same. I will try full movements and see whether anything stands out.
  13. What happens if you adjust rudder trim without disengaging YD?
  14. How did you identify the problem during pre-flight?
  15. AF 4590 - okay, not a fair comparison, but it was a catastrophic failure
  16. Perhaps someone should build a device that translate CTAF to ultrasound
  17. What I was pointing out is that the best way to get prices down is via economy of scales, but that in this case, you still won’t be able to find buyers at that price point. See @1980Mooney’s response. So since the market is fundamentally tiny, the situation we are in a natural consequence.
  18. Exactly - the market is small not because the product is not affordable
  19. I think there are more fundamental constraints. Suppose you could build the 1200lbs UL, pressurized, 300kts beast profitably for $80K provided that you could sell 1 million of them. Would you be able to find the buyers?
  20. Isn't a second NAV/COM required for IFR?
  21. There was a thread here pointing out that engine failure rates are higher than what we like to believe. The dashboard appears to confirm that. I'm very surprised that this is the second major cause after loss of control. On the bright side, the majority were non-fatal : this should motivate us to practice engine out procedures a lot more.
