Line Up and Wait
TV report said 6 people on board. They speculated the passengers were music executive David Shapiro and his crew.
This isn't relevant to the accident, at least not directly but I always wonder why someone who can afford to own/operate something like a Citation or other bizjet wouldn't have upgraded their avionics to be LPV capable. Is it a matter of just being cheap or is there just THAT much more complexity/expense involved in such an upgrade on these types of aircraft?It should be noted we don’t know the RNAV capabilities aboard the aircraft. If this was an LNAV-only approach, then it puts the step down at PALOS into play, which is right about where the terminal dive commenced. It would also explain the level off just prior.
Geez, depart New Jersey at 11:15pm for a cross country flight, what could go wrong?
Why not grab a hotel and fly home fresh the next morning?
Looking at the track again, he was so low that it's quite possible he went under most if not all of the wires. There's that strange anomaly where it appears to pop up about 100' a few seconds after crossing the wires, but then settles right back down - almost as if he tried to pull up or (really stretching here) caught the tail on a wire, which pitched him up briefly. Could just be a data anomaly as well. Appears to subsequently fly just to the left (south) of the left field light pole at that ball diamond before heading right into the neighborhood - maybe caught the (right?) wing on that?Reporting from Fox News now reports the aircraft hit a pole, shearing the wing. Fell into a large military housing area.
As far as turbine aircraft go, a 1985 CE-550 is dirt cheap to acquire (cheaper than some piston planes).This isn't relevant to the accident, at least not directly but I always wonder why someone who can afford to own/operate something like a Citation or other bizjet wouldn't have upgraded their avionics to be LPV capable.

Why not? Tell me what difference the ILS would make over the RNAV (LPV).Considering the coastal airports all had low IFR conditions, and assuming the ILS was operational, why would the pilot ask for an RNAV approach?

Perhaps, and I allowed for that in my statement. However, there are already several correlations that confirm that thr positional datapoints are already pretty accurate - for a big one, it points like an arrow to the first point of impact *after* the powerlines/light poles. But yes, the outlier at the end is pretty strange for data that’s otherwise lacking them. I haven’t seen any reports as to where any pre-ground contact points are, specifically.You are trying to read WAAAAY too much fidelity into internet reported data.
Could be. That assumes a non-precision approach (LNAV only), for which the published MDA is still around 300’ above those wires. You’d have to have the altimeter set to 30.22 or higher to produce an error that large on that night.Speculation about the altimeter setting.
For SP ops, a lot less buttonology, less stuff to f up, and probably lower minimums?Why not? Tell me what difference the ILS would make over the RNAV (LPV).

Ramona was VFR and isn’t much farther than Brown, which he had asked for. I understand that ATC and airborne aircraft are looking at different, more “official” sources, but as I posted in my first post, there is a big picture resource available to folks on the ground and anybody in the air that has internet access, in the form of AWC. Sure, it might lag a bit for real-time needs, and again, access while airborne can be a big problem, but a quick, slightly zoomed-out glance could graphically reveal the bigger geographic picture of weather-affected areas rather than trying to remember every suitable airport in the area and asking for weather on an individual basis, while you’re also navigating into the terminal environment.Could the ILS equipment on board have been unreliable, thus selection of the less precise approach?
A reversal to the east, off the coast to clear air, land and rent a van would have been a low class option, but...
For the RNAV LPV, yes it’s less buttonology than the ILS, but the minimums are identical.For SP ops, a lot less buttonology, less stuff to f up, and probably lower minimums?
Completely dependent on the avionics package. I've flown aircraft that require exactly zero button-ology difference between the two. And my current ride requires more programming and management for an ILS (still only a slight difference). Neither presents any issues - it just comes down to familiarity with your system.For SP ops, a lot less buttonology, less stuff to f up, and probably lower minimums?
And his speculation seems to be about a 29.92 altimeter rather than local, which was 29.89, in which case he’d be 30 feet high, not several hundred feet low.Speculation about the altimeter setting.

The other way around, 30 feet low. But your point stands - it's a relatively low error compared to the deviation.And his speculation seems to be about a 29.92 altimeter rather than local, which was 29.89, in which case he’d be 30 feet high, not several hundred feet low.![]()
7 out of 4 people get things mixed up.The other way around, 30 feet low. But your point stands - it's a relatively low error compared to the deviation.
haha! And I screw that one up at least 50% of the times that I get it right...7 out of 4 people get things mixed up.

Agreed, my point is just that there is not necessarily any decrease or increase in workload between RNAV vs ILS.Button pushing errors and correcting them are the first sign I need to get up for some proficiency practice with the electronics. But I always include some hand-flying as the main backup to screwing up with the buttons which usually happen at the wrong time (i.e., in IMC around the IAF). Hand-flying skills seem to last much longer and (IMO) are easier than the distraction of screwing around with the GPS / Autopilot buttons while trying to correct a programing mistake at a busy time.
I posted this earlier, but being lower in elevation, SAN was above mins but the pilot never asked for SAN weather.
The only thing I can think of that might have made a difference is if that airplane was non-WAAS. Max Trescott goes over the accident on his Aviation NewsTalk podcast and pulled the descent profile from one of the ADS-B sites. There are significant excursions from the glidepath that could mean a number of things. One is non-WAAS which then begs the question, why not use the ILS? The other is not flying it very well after a long day and night.Why not? Tell me what difference the ILS would make over the RNAV (LPV).
I’ve been wondering exactly that since the beginning. The profile really looked like a non-precision approach with no vertical guidance, with dive and drive level-offs right about where you’d expect them, save for the end. Also brings back into question the altimeter setting (even though that’d have to be a pretty egregious error to produce those results).The only thing I can think of that might have made a difference is if that airplane was non-WAAS.

I don't know why I didn't think about that myself. I ended up at Ramona a couple years ago as an alternate due to the same kind of marine layer.Ramona was VFR and isn’t much farther than Brown, which he had asked for.
And to be fair RNM isn’t always out of the muck (it wasn’t this morning), and SAN was also a viable choice that night.I don't know why I didn't think about that myself. I ended up at Ramona a couple years ago as an alternate due to the same kind of marine layer.
Wasn't a great experience. The people were unhelpful, borderline rude.
Their recommended driver never answered calls.
The tie downs were unusable because the rings were embedded in the asphalt. Then I got scolded for using a screwdriver to clear the rings sufficiently to get a rope through.
I called an uber to take me into town and, holy cow did I smell! I had been camping for three weeks and fairly modest opportunity to clean up. I had become totally nose blind. Got to the hotel, showered, went to dinner, came back to my room and had to put those clothes in a plastic bag. Still feel badly for that driver!
Then I went to Mexico for 2-3 months, walking across the border and leaving the plane in Ramona. When I got back I had a flat tire. I was parked right in front of the FBO and they knew my plan. No idea why they didn't bother to, you know, give me a call.
Lastly, I had hundreds of dollars worth of drone batteries ruined by being expose to the heat.
But, you know what didn't happen. I didn't end up CFIT trying to make an unwise approach. I guess I would make the same choice again.

That's another piece of the puzzle. Apparently, the AWOS at MYF was out of service.Also brings back into question the altimeter setting (even though that’d have to be a pretty egregious error to produce those results).

“When the altimeter setting(s) on which the approach is based is not available, the approach is not authorized” AIM 5-4-5.a.4I went back and listened to all of his prior handoffs from LA Center and I never heard altimeter mentioned to 6DS specifically.
However, altimeters all over the area were right around 29.92. Departure altimeter in Wichita was 30.05, even TEB was around 29.9-something. None of that would explain an altimeter setting of 30.22 or higher that would cause such a gross error. Nothing near his flightpath, outside of a few locations around a surface high over the Four Corners region, were reporting anything over 30.09, and he’d have been standard in the flight levels at that point, anyway.
But that he made other assigned altitudes and minimum segment altitudes prior isn’t really adding up to an altimeter setting issue. There are so many possibilities on this one.
