Pull up. At 37,000 feet. That’s the warning... . Terrain ahead. Pull up. There’s no mountain up there. Just cruise. This has been going on more than a year. Plane comes in. GPS 1 fault. GPS 2 fault. ADS-B also. Sometimes the other 1 and 2 faults with it....

Cruising at FL360 over the Congo forest in the DRC and got the exact same thing on a 737-800—hard EGPWS warnings ("TERRAIN, PULL UP") triggered by spoofed position data.  Fortunately, @Boeing recently published the “GPS Data Unreliable checklist ”to help crew recognize ,manage such issues and transition safely to IRS and conventional radio navigation if required. Stay sharp out there! ✈️ #AvGeek #Boeing737 #PilotLife #Aviation #FlightSafety #GPSSpoofing

You’re lucky. Mine kept yelling, “Eject! Eject! Eject!”

This happened over cartel controlled territories in northwest Mexico for almost a year. Even MMCL ATIS makes mention of it for their RNP approach

Last month leaving Germany for Hong Kong we got spoofed over Bucharest. Lost both left and right gps, and never got them back. ANP never exceeded RNP. Just let ATC know and the company. Wrote it up in hkg.

How isn't air pressure enough to know that there are no mountains?

What if flying on night where there is no visibility

Classic. The box is doing exactly what it was told. EGPWS trusts the GPS position, the GPS lies, so it shouts terrain at FL370. I reset it, sign it, and wait for the next one. LRU comes back clean.

Very weird. As there is no RAD ALT signal (both PFD show STD below ALT Tape), how can the little plastic man shout 'Terrain-Terrain-Terrain' ?? Position is still valid, because the FMS should normally use DME/DME.

How long do the warnings last?

Usually just while you’re flying through the interference pocket ...anything from a couple of minutes to 10–15 depending on how wide the jamming area is and your groundspeed. Once you’re clear of it the GPS normally comes back after a reset, though the EGPWS can sometimes hang onto the junk data a bit longer and keep chirping until you cycle the box.

Fly safe 🙏🏾 GPS spoofing is a serious issue.

I had a similar thing in cruise but it was caused by one of the radalts getting water underneath the bonding. When we had flown through precipitation and then levelled off, ice crystals would push the antenna away from the skin, setting off the pull up. Most annoying.

Typical to a specific manufacturer or same issue on other aircraft?

Does this mess up with autopilot or it continues flying straight?

Testing one of the best safety features of an airplane, the “Enhanced Ground Proximity Warning System” (EGPWS, pronounced E Gyp-Wiz). It’s part of every preflight check. Sound on! It’s a warning system. While the jet has separate warnings for things wrong internally, EGPWS is concerned about what’s outside the jet, not what’s inside. It’s primarily concerned w/ terrain & obstacles…EGPWS can “see” outside when pilots can’t. It doesn’t actually see anything, though. There are no cameras or lasers. EGPWS does use the jet’s radar, but not for detecting terrain. (We’ll talk more about radar in a minute, but it’s not useful for orienting yourself to terrain in the vertical. It has a “map” mode that you can use to “paint” things like cities, lakes & shorelines, but it only knows how strong the reflection is & how far away, not how high. We almost never use it in map mode, anyway) EGPWS uses the jets navigation systems – like GPS, Inertial Reference, Altimeters, airspeed, etc. – to plot a position in a virtual world. This world is contained in a database on the jet; it’s constantly plotting your position & then estimating where you’ll be in the next few minutes if the trend continues. The virtual world database knows where the mountains are. When you get close to airports in the database (not all airports are in it), it knows where the buildings & antennas are, too, out to a certain radius. Past that radius, it stops caring about the manmade objects. Anyway, it can tell if you will hit something on your current trend & will issue various warnings. It can give you up to 60 seconds of warning. It starts out slow, like saying “CAUTION, TERRAIN”, but if you don’t fix it, it gets serious…“TERRAIN, TERRAIN, PULL UP!”. You’re 20-30 seconds from impact. It’s not a miracle worker, though. It can wait to give you a warning that you can’t fix. Imagine flying toward a 10,000’ high cliff at 1,000’. A 60 second warning will not be enough time to climb 9,000’ & clear it. Or, it sees a mountain to your right, but your current path is clear. It doesn’t know you’ll do a 90° right turn once abeam the mountain. Now you’ll get some late warnings. EGPWS has various other functions. If you get on the approach but haven’t configured to land, it will say “TOO LOW, FLAPS” (or GEAR). If you start getting below the glidepath, it will say “GLIDESLOPE”. Start descending right after takeoff? “DON’T SINK”…and if you do keep sinking, it switches to “PULL UP!” Now, EGPWS doesn’t use the onboard Doppler radar for any of these functions, but it does use it to detect windshear. EGPWS doesn’t care if you turn on the radar or not, it turns it on itself when you push the throttles up for takeoff or when you descend below a certain altitude on approach. It takes about 12 seconds for the radar to build a picture from that point, but once it does, it can “see” windshear. The Doppler detects this by bouncing radar off of particulates & reading how they are moving at different altitudes. The particulates can be dust or just humidity…the radar can’t read air molecules by themselves. So, it’s still possible to get windshear the radar doesn’t see on very dry, clean days. EGPWS hates windshear. If it detects it, EGPWS replaces your screen w/ the radar – even if not turned on by you – & starts with a gentle warning to “MONITOR RADAR DISPLAY”. If you get closer to it, you get “WINDSHEAR AHEAD” (on takeoff – abort if you still can) or “GO AROUND, WINDSHEAR AHEAD!” (on landing). EGPWS is great, but can’t actually move the jet. It’s not connected to the controls in any way. Some fighters do have that capability, but not airliners. The pilots have to fix it. OK, that’s a brief summary of EGPWS. As usual, I’m dramatically simplifying things for a non-techie audience…there is much more to it & different models of jets have slight differences in how this all works. The 737 MAX has some improvements, w/ different voices & even panic, but I don’t have one to record, sorry!

Things have gotten so expensive in America, this woman says “I have my Masters in Business Administration. My husband is an Engineer — We are living paycheck to paycheck, like it is so hard - Our mortgage has gone up $500 since when we first bought it - Property taxes, they just keep going up and up. So with that, our mortgage just keeps climbing too - We have two kids. With kids comes diaper prices, comes formula, comes everything else that comes with it - Daycare, we were able to find a daycare that's actually pretty inexpensive compared to a lot of other daycares. And even with that, it is still costing more than our mortgage does every month. I'm just so tired, and I know everybody is in the same boat too. Prices are going up for literally everything.Everything. But when it comes to pay, our paychecks will go up, what, a couple percent, but nothing compared to inflation on everything. I just don't understand how we keep doing it. And where's the breaking point? Where does that come in? When do things turn around because there's no end in sight. — We're given this promise basically when we're younger that if you get the degree and you do this and do that right, then like, you'll be set, you'll be golden when it comes to money and not have to worry about it. And then to grow up and face the fact that all of that's bullsh*t, like they fed it into being such a lie in such a trap basically, that everybody is just buried in different student loans. Everybody is buried in different kinds of debt that we'll never get out of, that they promised us would create a safe and happy thriving future. None of it's there. So thanks, boomers and beyond. You set us up great.”

Brian Urlacher says the one play from the Bears’ Super Bowl loss to Indianapolis that he still believes could have changed the outcome was when he dove on a fumble instead of trying to scoop and score, and explains how he abandoned something they had practiced for years in that moment “What happened? So what I remember, if you want to be personal, like what I didn’t do in that game, so all year long, or all of Lovie’s whole career, we practiced picking the ball up when it’s on the ground and scoring. No matter if it’s an incomplete pass, a fumble, whatever it is, we pick it up and score. “Mark Anderson causes a fumble, and it’s right there in front of me. So if I pick it up and score. I mean, I should have picked it up. I tried to dive on it, and there’s no one in front of me.” “So if I just pick it up like we’d been practicing for his whole coaching tenure, I score. There’s no doubt, because back then I could still run. But I try to dive on it, I knock it toward our end zone. We get the ball back anyway, but we don’t score on the drive. We end up turning it back over to them.” “In my mind, if I pick that ball up and score, we win the game. That’s what I think. I don’t know when that was in the game, maybe second, third quarter, but that’s what I remember. But we just, God, we made so many bad plays. We busted a coverage on Reggie Wayne’s touchdown. We’re supposed to play Cover 2 on third-and-13. Safety didn’t get the check, allegedly, so we play Cover 1. Just not good plays.”
