I still think they would benefit from a ground beacon that has cameras and radar and some LORAN like thing going on as a backup. Ground reference is always gonna do something IMO. And you can armor them a little bit too compared to a sat. And the other thing too is you can start putting functions in em to do stuff like clean solar panels (car wash thingy), recharge cells, replace modules.. I guess thats outside the scope of a beacon though. |

One of the most common causes of malfunctions with software-based systems. Assuming the conditions they will run under are limited to the very few that have been thought about in some office, for probably not long enough. --- End quote --- Yeah, they should have specified: Make it not crash. :-// --- End quote --- How would you design the code to cope with detecting a sensor failing, yet not failing the sensor when the data is suspect? |

1878 "It was the foolish fashion for the fine gentlemen of Horace Walpole’s time to carry two watches—a fashion which that wit explained thus:— “One of them is to show what o’clock it is, and the other what o’clock it isn’t.” Judging when a sensor has failed due to a jump in readings, compared to flying over a cliff... it seems pointless because even then you have no alternate sensor or worse yet it also reads a jump and gets disqualified. SPLAT. |

Do modern planes have the ability to use data from the tower to land? Like a computer link between the radar of the air port and the runway? I am not sure actually, I don't know that much about aviation. But I would assume that if a plane has a malfunctioning altimeter or whatever, they could ask the tower to use their data which would be pretty good and at least offer a better landing outcome then eyeballing it? And that if GPS went out for whatever reason, they can find the air port based on radio transmissions. Theoretically someone could give them data using a broom stick and a walki talkie too. |
