AP, seems like a lot of the things you want are available.
Are they available for a cost similar to the cost in a family car?
Speed limits? Do you have a lot of problem exceeding speed limits in the planes you fly?
Well, there are 2 sides to speed limits. In an aircraft, going too slow is more of a safety hazard than going too fast. Nevertheless, for airspeed we have one indicator, with markings from the earliest days of aviation to indicate VNE (red line) and VNO (maneuvering speed).
Junction view and lane assist, I will just have to plead ignorance. I do not know what that means to aviation.
I tried to explain how that might apply to aviation. "For airplanes, an approach view including attitude for landing that helps you to identify the airport and its surrounding vicinity." "For airplanes, the correct approach to arrive at the downwind on a 45* with or without crossing over the airport. Display correct downwind placement so you can adjust for crosswind and get perfectly lined up."
The panel mounted GPS's I have used have as big a screen as I would want. There is a limit to the amount of panel space available in aircraft.
Resolution is pretty good. Not sure how that would help safety. However the MFD's have very good resolution, IMO.
Understood. I would not mind being able to pull out my ADF and substituting the type of display I could get on a tablet.
Updates. I am sure if you could live with three to four year old information as in auto updates that might could be arranged. The map updates for my Garmin auto do cost and actual data only comes out every few years. I think getting new data every 30 days might never be free.
How about reasonable cost? How about automatic?
Voice command and track logging, that would be interesting.
My panel mounted GPS is integrated into my comm radio. How hard would it be to integrate voice recognition so that I can do my Captain Kirk simulation, "Computer, change flight plan to include the route change from ATC."
Detours and re-routing. Again I plead ignorance. Perhaps an example?
See previous.
TFR's, Yep, got that in the units I have used.
Even popups?
Traffic, yep, got it and precipitation, and lightning also.
How much did all of that cost you? Is it certified IFR?
Certainly, if you are satisfied with the safety allowed by the FAA through both regulatory denial or financial denial, then you are as safe as you want to be. The FAA does not need to change and any errors are yours alone.
However, my contention is that many of the pilot errors we see today could be mitigated by using the types of technology currently available to car drivers today if only they were allowed and affordable.
Just the other day, I saw an advertisement on TV for a system you can put on a car that alerts the driver if s/he is impaired and needs to stop and get some sleep. How many lives could that save in aircraft? Would it be legal to install on a plane?
