But that's what we train for. That's why aircraft and pilots have redundancy to work around any single possible point of failure and why you practice it until it becomes natural. Because of the NOTAM I'd already have a VOR tuned in, and once the GPS went inop I just fine tuned it to get a radial fix on the VOR. Also tried to never lose my bearings with my MK I Eyeballs either. No big deal.
I feel bad for everyone that lost their lives here, but this is why competence is critical. There's a litany of errors the pilots made. And the article tries to pin a bit on the controller, but no, ultimate responsibility is on the pilot in command, FAR/AIM is clear on that.
If these allegedly instrument rated pilots had been properly drilled by their CFI's and properly grilled during reviews and such this should've been an easy flight.
Also, "just ask Kennedy". Wired bringing that into the conversation is perhaps relevant but not in the way I think they intended. JFK Jr lacked basic airmanship skills. His aircraft was 100% functional until the moment it impacted the ocean.
Some professions simply can't be go-along-to-get-along social clubs. Safety culture centered on competence and performance is key.
Even in the absence of GPS jamming, you can effectively lose GPS for all kinds of reasons in a plane--a connector failing somewhere on the back of your panel, a wire chafing through, etc. GPS is nice, but it's probably a lot less reliable in most light aircraft than the other options.
It's been 20yr since I've flown a plane, so maybe attitudes have changed, but my instructors always stressed the importance of always being able to fall back quickly and seamlessly to a paper chart, your watch, flight computer, and basic instruments. Because you will lose everything else at some point.
In our operation, departing to an airport with missing weather reports would not be permitted, so in a Part 121 scheduled service this flight may not have been able to dispatch legally.
Airliners have DME/DME triangulation which allows them to achieve area navigation (RNAV) without GPS. The interference would have precluded a GPS approach but may have left the GPWS ("Terrain! Terrain!") alerts unaffected.
In this case the ILS was not available, but only because the local altimeter setting was not available. In this case I could accept a visual approach, but use the ILS to provide lateral and vertical guidance towards the runway.
There are many things I have learned about flying from years at the airlines that I would have had to learn the hard way at a Part 135 or Part 91 operation. One of those things would have been when to say "no".
Take the airplane to a mountainous airport with missing weather reports at night with NOTAM'd GPS interference? No.
Do a visual approach on a moonless night with no GPS for terrain awareness? No. Fly the ILS even if it's NOTAM'd out.
In this case, IMHO, the pilots had become complacent and lax in their navigational rigor because of the fact that GPS makes a lot of the slightly less automated systems unnecessary, and people get used to that workflow.
If the flight crew had been looking at their map and using it to inform them about the mountains in their path, fixing position by the VOR and DME, or even just a stopwatch and compass heading, they would have easily known they needed to be at a higher altitude. Not being precisely sure of their exact position, they should have at least been maintaining the minimum safe altitude for the area they knew they were in.
But unfortunately, people get so used to looking at the shiny screen giving them effortless situational awareness that they forget all of the rules and habits that kept pilots alive for the last century before glass cockpits were a thing, and they forget that mountains are the tigers of the air, always waiting to catch pilots unaware.
This is a useful cautionary tale not only for pilots, but increasingly for humans in general as we become accustomed to a new kind of instrument that allows us to offload a great deal of our cognitive focus to a tool that may sometimes fail.
The animation uses what looks like an airliner, and shows the jamming as a sort of bubble that directly sends the airplane into a crash.
I found it disturbing when I looked at it, it does not represent the story well, and I think that's irresponsible.
Instead, the pilots saw the airport visually and requested a visual approach. ATC cleared them, and told the military they could resume GPS jamming, meaning any terrain awareness warning system the pilots might have had or been relying on would no longer work. The visual approach involved a left turn and descending directly over the mountains.
blancolirio's video about this (second one, after the prelim investigation report): https://www.youtube.com/watch?v=Dcyup4xVQuM
He focuses on the fact that both instrument approaches were impossible under the conditions; gps jamming made RNAV impossible, and an inoperable weather broadcasting system at the destination made ILS impossible. The alternative, visual approach in mountainous terrain on a moonless night, is clearly unwise for inexperienced pilots.
One thing he doesn't mention, though, is that ATC could have waited until the plane was on the ground to tell the military they could resume GPS jamming, knowing this was a medevac flight lacking the usual planning and level of caution of typical pilots.
> About 0005 the ARTCC operations supervisor contacted [the military] to stop jamming and at 0007:34 ADS-B data recording returned to 2-3 second intervals.
> The flight crew again reported they “[have] a visual on Ruidoso” at 0008:30 and that they could “go visual.”
> About 0010, the ARTCC operations supervisor informed [the military] that the airplane was on a visual approach and that they could resume jamming.
> The airplane impacted terrain about 250 ft southwest of the last recorded data point at an elevation of about 9,950 ft, and about 730 ft east and 230 ft below the Capitan Mountains Summit Radio Facility, located at an elevation of about 10,180 ft.
The image of the map from the report really helps me understand the path. It seems like the aircraft began visual approach and didn't know where it was, or didn't know about the mountain.
> The ARTCC controller subsequently cleared the flight to SRR, cleared the flight for a visual approach, and informed them they could cancel IFR in the air above 9,000 ft msl or they could cancel their clearance via the flight service station after landing. The flight crew acknowledged the clearance and responded that they would cancel IFR “in just a couple of minutes.” There were no additional radio transmissions received from the flight crew.
It's not at all clear to me that they did go visual. They communicated that they intended to cancel instrument clearance later and that suggests they were still using it...
Pilots train to navigate without GPS. Or, rather, they should...
If I'm not mistaken the US still has the 1500 hour requirement that was illogical even when it was first introduced. It was introduced as a response to a crash by poorly trained pilots, but both pilots in that crash had over 2000 hours each, so the lesson should clearly have been that a raw number of hours is a very poor indicator of competence.

It was a visual approach at a moonless night at an airport in high terrain, this was pilot error unfortunately.
It's quite easy to say "no big deal" while calm in an office, but it's really different when you're busy flying and then there's the extra workload of trying to understand what's happening, attempting to fix it, and so on. Imagine "debug bug in production while driving a car" for a rough comparison, although I guess planes are probably better equipped for loss of GPS?

What would have been the "skill issue" difference people keep mentioning? It's getting really frustrating how reckless the US military is with the skies. They keep putting people in danger. I can't help but think about the DCA crash due to the continuity of government drills.
There's no reason they should have been flying dark for a drill that night.
Back when i used to sail, taking bearings with a sighting compass on two points on land / two buoys always gave you a fairly accurate position. Not sure if there is a sighting compass equivalent with elevation angle too on planes?
Individual GPS signals typically arrive at the antenna below the receiver’s thermal noise floor and the system relies on processing gain in the receiver to generate a fix.
how about ANS (aka R2-D2) the 1960s version of GPS that used stars
instead of stars, preload all the known positions of LEO constellations
can they put this on a single chip 60 years later?

Air traffic control also failed here.
A controller who has the capacity to spot something that seems off like a wrong heading or altitude might ask the plane if they are OK, but unless they are deviating from a flight plan in controlled airspace, they are more likely to assume VFR and pilot knows best.

WSMR does enough GPS jamming that I'm surprised these pilots didn't have more experience with, or at least expectation of, it happening.
GPS NOTAM'd as unreliable on a dark, moonless night?
Fly the ILS approach (or fly a visual approach along the track of the ILS approach backing up your visual with the radio signals). That will give you terrain and obstacle clearance all along the route using locally generated navigation signals that will be entirely unaffected by GPS jamming.
I would 100% (and have) take center's altimeter setting and fly the track of an ILS or localizer rather than "whelp, nothing can be done..." This was VMC; you don't need a local altimeter setting to be safe using the radio navaids; you would need it to legally fly the approach as an ILS approach.
It appears there were too many sources of confusion. GPS jamming, moonless night, busy ATC, not planning on VFR before takeoff, 20 minute short flight, instrument approach disabled, young pilots, mountains, and perhaps others.
Flight safety is about removing entropy and there were several steps which could have been taken, including not flying at all because of forced VFR on a moonless night near mountains.
This has not been the practical reality for many years for IFR flights (arguably not for VFR flight either but some of the good old boys will still argue that you should still be using a map and compass).
In Europe the minimum requirement has been B-RNAV and aircraft are controlled with reference to intersections which have no defined relationships with underlying VORs, and an expectation of being able to navigate direct to one from any arbitrary point in space. Airliners generally get away with this because they have DME-DME disciplined INS. Smaller aircraft, well the backup is vectors from ATC.
Vectoring by the controller to a visual or ILS approach still works but they'd be juggling a lot of planes. And while lots of the bigger/older airports still have ILS, many VORs and DMEs are being retired and many smaller airports don't have ILS at all.
Denied access to GPS in a large area in bad weather would likely result in lots of flight cancellations and contingency plans getting put in motion to get anything still in the air landed safely. But controllers would get very busy and ILS runways very congested.
Here in Europe, there have been a few cases of GPS denied areas especially closer to Russia. Mostly pilots and controllers at e.g. Helsinki airport are able to deal with this.
But yeah, IFR is getting more dependent on gps approaches…
which is incredibly stupid because it becomes trivial to disrupt air navigation. It’s a bit better with newer chipsets that support GPS, Galileo, GLONASS, and BeiDou… but I’d venture that when the military is jamming I’d does them all. I can buy a jammer that will take out GPS over about a kilometer for less than $1k. They are used all over the place by criminals in many countries, because there often aren’t standardized addresses and if your drug house can’t be located on gps in the favella, you get a lot more warning before a raid. That same transmitter with a directional antenna could knock out a 10 degree sector for 30km.
Pilots were so used to "the plane won't make a mistake" that they were not aware/not trained properly about things that are nothing to do with the FMS like frozen pitot tubes and also that the autopilot has a number of "modes" which mean you need to go back to basics like altitude, attitude and air speed.
If it isn’t true, then the military is partially responsible for the crash of this aircraft.
One technical point that initially puzzled me was why Spidertrax appeared to retain GPS coordinates while the FMS did not.
My understanding is that certified FMS GPS receivers use Receiver Autonomous Integrity Monitoring (RAIM) and other integrity checks. During GPS jamming, the increased noise and degraded signal quality can cause the receiver to determine that it can no longer guarantee a reliable navigation solution, resulting in a NAV FAIL or RAIM warning.
A tracking device such as Spidertrax, on the other hand being a glorified telematics grade positioning device, is designed for best-effort position reporting rather than certified navigation, so it may continue outputting an estimated position using noisy GNSS data and motion filtering, even when that solution is no longer suitable for primary aircraft navigation.
In any case the news (and ntsb report) points that they are tied, not responsibility.
SRR is serviced by two instrument approaches, the ILS or LOC RWY 24 and the RNAV (GPS) RWY 24. Both instrument approach plate notes section contain the following statement: “When local altimeter setting not received, procedure NA (Not Authorized).”
IFR approach was not possible, the flight plan was unrealistic.
Questions must be asked about how and why we got here rather appeal to submission.
Had they known they wouldn't be able to rely on GPS, all that back and forth with ATC would not be needed, and they'd already have a plan B and a plan C for navigating.
It's unfortunately all slices of swiss cheese aligned perfectly, but I'd still blame the military for poking extra holes on the GPS slice.
This week I witnessed a similarly illogical argument between someone who thought they could argue about AI in movies and someone who actually works in the movie industry and has years of experience. The hacker was lecturing the movie person about why they were wrong about the future of the movie industry, with zero experience to back it up other than "I dabble in AI and watched some movies".
The only correct conclusion here is more investigation is necessary than what has been publicly published.

So you’re pointing out that they requested VFR, got clearance for it but still were flying under IFR rules? Basically the transition to VFR hadn’t completed fully?
When they accepted the visual approach, they took responsibility for navigation and terrain/obstacle clearance.
Also someone is correctly pointing out to me downthread that a visual approach is technically an IFR procedure under IFR not VFR flight rules (the latter basically meaning you aren't using instruments at all). I'm assuming IFR in the summary is referring to the non-visual approach (rnav or ILS) but the preliminary report is I suppose ambiguous as to that.
