If it's not broken don't fix it I can't see why on earth flying +V while above MDA (or 2D MDAs) is problematic? I get it's advisory, it does not mean he should disable it Looking at recent mannual for latest units, it seems impossible and avionics won't let hime do it...I think my friend is going to get fried next week on NDB or VOR/LOC with distance and timer, let's hope he will not get to disable ground speed, wind vector, flight path vector, track diamond as they make flying non-precision easier (aka safer)

It seems to be a requirement for IFR exams here: - You have to fly 2D CDFA without any slope and 3D precision on official slopes (ILS/LPV) - You have to do RAIM computation at ETA in case SBAS is not available (it's a piece of theatre, I don’t think anyone has died because of lack of sattelites ) GTN XI seems to prevent both possibilities

In G430W to an airport that has LPV & LNAV: - If you disable SBAS 2nm before FAF while in TERM, you get LNAV+V using NAVSTAR only, as you said it's computed on GPS only - If you disable SBAS after LPV annunciation, it treats the lack of SBAS as integrity loss for an LPV, then fallback to LNAV without advisory glideslope In GTN XI, it seems one can't do RAIM, SBAS = OFF and can't disable official/advisory slopes

Yes all the steps above work in GTN NXI/TXI simulator, I was referring to the steps in navigator while flying the aircraft, those menus just vanish whole airborne, I will do a screenshot next time I fly my friend aircraft...then they re-appeared inside the hangar The examiner wanted to disable +V in LNAV+V so that his student can fly 2D procedures like in the old days: counting distances & altitudes, he also wanted RAIM prediction... I am not sure why one would disable augmentation or advisory glide in real life? I was told one need to tick EGNOS and untick WAAS while flying RNP in Greenland, honestly, if one need LPV minima there they are pretty much dead LOL

I use it regularly in Europe: for 20$/yer one gets regular updates of ECMWF model every 4h, which is gold standard down here... It's a bit of "kitchen sink" with load of functionalities and light documentation, however, it's the best tool one can have to benchmark against GFS or compare to BBC weather

Hello, In GTN XI, does anyone know how one checks GPS status? selects SBAS provider? get RAIM prediction? disable +V? I would have expected these to work, Home -> System -> GPS status -> SBAS Home -> Utilities -> RAIM prediction -> “compute RAIM” However, I can't find these in the menu? I was scratching my head in the hold trying to disable +V vertical guidance with no luck (it seems these options are not available when one receives WAAS augmentation)

Does Canada/US allow GA to Tech-Stop (like airliners when you land and get fuel while staying airside in H24 international airport with permanent staff), can one get fuel while stretching their legs airside? assuming, one complies with eAPIS, CANPASS, CBP…and sends back-to-back flight plans in big airports Just personal curiosity, I am based in Europe and not planing to fly to Alaska anytime soon: it’s still in the dream phase (I did NYC-Canada and Florida-Caribbean with Mrs). In France/UK, GA is not allowed to Tech-Stop like airliners, however, some airports are relaxed with it, especially, for regular pilots getting fuel without passengers

We went down to Spain to chill and eat some paella Found it, it’s the new clouds factory over the Loire river !

Flew to Duxford museum in UK, Which fast aircraft don’t have trim tab and whole tail rotates? Blackbird and Mooney they had an interesting pink Spitfire, she is gorgeous or he is handsome (I checked under the pants, I know what I saw and I won’t disclose any gender) While pink painting is “à la mode” these days, these Spitfires were actually pink in 1940, they flew at dawns and dusks, like pink USS Winslow, Pink Panther and Pink Sherman (not obvious from Black/White WW2 pictures) https://www.wearethemighty.com/mighty-history/why-this-world-war-ii-british-fighter-was-painted-pink/

It’s 77 M20J, I was puzzled as well it’s a lot of water, however, it was sitting outside for 8 months and only did 2h, it’s now in a hangar, the owner managed to start and do ground run yesterday, he will investigate with his mechanic Shame it’s not flying that much…

Thanks, I passed the info to my friend (we drained all of it last weekend, however, we have not removed the spark plugs, he needs to act on this urgently)

Does anyone know how to start Mooney (for ground run) if they suspect water in the tanks? I was helping a fellow Mooniac this weekend, we sampled the main tanks and the gascalator and found lot of water in tanks: allmost 1/8 of a gallon ! Aircraft did not start after load of attemps, even on auxiliary power...it's finally, in hangar now and we are giving it a go in two weeks (we did drain all fuel and we plan to refuel it again with pre-heat next time) We are not planning to fly it anytime soon until everything is checked, sadly, that beauty has been sitting for a while under rain and dirt, way too much this year and has too much gremlins...

That may probably explain the selection bias why we don’t hear much about corporate business (while for celebrities it’s part of the show to make a show out of it) Sounds like one should get J3 with no electrical system

I edited, yes they can track with data crunching and spotting as well…

You can have temporary ICAO Hex code via PIA https://adsbperformance.faa.gov/PIA/Application.aspx Obviously, if one can get the temporary hex code and placeholder tail (they bribe someone or do lot of data crunching) they can still track that on ADSb

I understand getting ADSB & ModeS privacy is easier and cheap these days, at least in FAA land, it would cost way more than hiring her lawyer to muddle with the pigs? It's interesting that celebrities jets (pop-star, football, soccer...) make a whole story out of flight tracking, however, when you look at corporate jets they seem to do just fine to keep their sensitive trips under the radar

I gather it’s impossible as these are calculated by operator (airlines, commuters, private pilots) and one can’t distinguish between 2D/3D capabilities unless the glideslope is live and well checked (LOC/ILS mins? GPS or FMS LNAV, L/VNAV, LPV?) One can check altitude with airport QNH against GPS WAAS altitude during vectoring or feeder airway leg (errors are under 50ft) and check any altitude discrepancy against distance at FAF or other fixes, these will flag scenarios like clogged static ports or wrong altimeter setting On something as robust as the glide on ILS or LPV, altimeter errors are of secondary: they won’t matter that much, if the needles are in the middle the aircraft will fly all way to touchdown point anyway (on ILS, one has to take care of false glideslope or irreliable signal, however, these gets flagged by other traffic and from ground speed to vertical speed check) Also, it’s really hard to mess up these days with extra awareness from Synthetic Vision, if HSI/GS is dead in middle while flight path vector is not on threshold something is wrong…I gather, someone flying privately under Part91 can legally look at an iPad with ForeFlight Synthetic-Vision and he is free to cross check QNH altitude versus WAAS altitude (the crew who flew 6ft from 27R at Charles De Gaulle don’t have that luxury, if they were equipped with WAAS, LPV, Synt-Vision…we won’t be having this discussion)

Give it a good 2700rpm & WOT until it screams and burn all the moisture, lead and sulfure, you need to warm up your oil/cylinders past 200F/300F and fly that for while, then you can bring it back to 20/20 LOP cruise What you can’t do is fly it 20/20 all the time, this gets you the same result as people who are doing ground runs instead of flying, that does not get cylinders and oil hot enough and likely more bad for the engine… In any case, flying at 20/20 is better than no flying

Took the kid (and my instructor plus his wife) to see Air Passiom Museum in Angers (LFJR) After a dreadful winter, the sunny weather started to appear along the Loire Valley in France

He beats me to it, there is always number1 for the approach

First flight of the year 2024 was in a friend J3 (Mooney was out for maintenance), the goal was to regain passenger currency after 90 days break, I was even tempted by asking for 6xIFR approaches on my handheld ILS, I settled for one big hole to VFR myself back into the grass runway First flight in Mooney at night after work, the full moon was over the tower (who does not prefer full moon night flights)

Yes it will be great to get a PIREP if G3X+GTN would flag bad QNH that bust DA on LPV Yes barometric altitude is used in augmentation checks before faf and in vnav or vpath en-route, for the latter it’s different as it’s PFD/HSI that emulate difference between target altitude and bugged altitude and sets a descent profile on that like fake glideslope, however, it does not care about correct or wrong setting: VNAV does not flag mixing STD and QNH while in cruise Do you have VPATH guidance with G3X+GTN combo? I recall this works in G500 txi units

Is your Mooney GPS connected to BARO inputs? I recall PA46 G1000xi and SR22 (G5) with G1000Perspective had barometric data, it seems possible in integrated PFD+MFD? I doubt standalone GTN does this, it’s you PFD that gets QNH? it's too "modular" My understanding GTN doesn’t have baro input or encoder altitude input? on GTN/GTX installs for ADSB with RS232, GTX gets altitude from encoder (GAE12) and position from GTN and you can’t send baro altitude to GTN, I doubt GTN is aware of QNH? For sure, GTN can’t handle BARO L/VNAV only SBAS L/VNAV (we tried it in Thailand ), I would be surprised if it’s aware of QNH and I would be interested to know if the warning exist tough? On other other avionics maybe, you have ALTimeter Setting Monitoring (ALTSM) function… https://safetyfirst.airbus.com/use-the-correct-baro-setting-for-approach/

My IA thinks that would work as well

I noticed we have not started this?
