- This video is used to explain to B737 Engineering students how the navigation and autopilot systems are used to carry out a Cat 3 approach in the B737NG. It is not narrated as that is done in the classroom. It is not to be used for pilot training.

Checklist:
Flaps 1 notch
Shake jar of marbles
Check
🤣
Boy do I wish I had a sim like this
That’s barometric altitude above sea level. It’s the height of the airfield above sea level. The radio altitude shows the actual height above ground.
Very cool. Thanks for the demo.
Nicely demonstrated.
Wirklich ganz tolles Video!💪
👍😎🇦🇹
Excellent video….yes I also want a Sim like this….
Was it heavy? I'm no pilot, but just thought 155 knots for landing at flaps 40 seemed a little high for a 737.. :)
Yes, the wing tanks almost full as it was a single circuit from take off to land. Speeds are calculated by the flight management system.
The 737 is a pig. That’s the normal approach speeds. The A320 is about 15-20 knots slower on approach and landing. The 737 lands faster than a 777,767,757 or 747
This video was recorded in simulator and is heavy to safety land
@@aubreyburke6829dude it was just because he did one circuit and had a lot of fuel left. On a real flight the landing speed would be lower.
@tekavia What does the flaps do for landing?
I thought the FMA would read “LAND 3” for cat iii landings? What determines when the FMC says LAND 3 vs CMD for an auto land?
Pin programming on the computer. It's a customer option as to what legend is displayed.
Que tecnologia incrível.
Just asking did u do the engine start switches cont for landing procedure and arm speedbrake ? And setting the go around altitude when g/s capture ?
That is correct, though in the event of forgetting to arm the Speedbrake it will deploy automatically. The go around altitude for this approach was 3000 feet.
Nice buttered landing
The auto trim wheel noise is annoying... I can't imagine how tricky it must be to do it by hand. Thats a big jack screw in the back.
In the real aircraft the noise level is much greater so the trim wheel is barely noticed as it gets drowned out and we have headsets on. For this video I reduced the sim engine noise level so the trim wheel appears louder.
Why was your IAS above the reference IAS ?
THANKS FOR SHARING.
I think I added 5 knots. Probably cos I flew the classic and not the NG.
Can those trim wheels be turned manually?
Yes there is a handle that is stowed on the trim wheel.
Antiquated system, still no rudder channel despite all the “upgrades” so no CAT3B….
YAW DAMPER
@@TheWidebody747 your point?
why was the altitude still in 340 when you touched down??
Because he probably had his altimeter set to (MSL) Mean sea level instead of (AGL) Above Ground Level.
@@broca246 Ohh I see, never knew this, thank you!
@@Stealthy77it’s barometric altitude, always show above sea level
@@Barikkel Got it!
@@broca246 To add to the folks that already answer you, I'll add my two cents. 😀
From 18,000 feet up, 29.92 is used as the barometric pressure standard to calibrate the altimeter. Below 18,000 feet, the barometric pressure of the area/airport you are flying through/landing at is used. As has been posted, the "340 feet" is his (and the airport runway) altitude above sea level.
Qas the minimums call supposed to be that low altitude?
Yes, on a cat 3 approach the minimums are set at 50 feet radio altitude.
Wow
What is that, that sounds like a broken washing machine?
It’s the stabiliser trim wheel. It will change the stabiliser position as speed, thrust, pitch or configuration changes. It will do it automatically with the autopilot engaged.
@@tekaviathanks pal!
I thought he meant how to land in a Cat III hurricane 🤦♂️
LMAOOO
The trim wheel sound was my first indication it was a home sim. Great looking but the sound of the trim not so much. Boeing has that sound perfected lol.
You are wrong I’m afraid. It’s a professional sim.
LE FLAPS TRANSIT? Is this plane French?
Ha ha! Good one. I’ll use that joke in my lectures!
@@tekavia glad you enjoyed that groaner. It just made me think of Pepe Le Pew when I saw it and thought Le Sigh.
Yes but weather good so visual approach
Yes, but if a B1 engineer needs to upgrade the auto land system then a practice auto land in Cat 1 conditions is requested. The auto land is then upgraded on the confirmation of the Captain. Whereas a B2 engineer can upgrade by doing a Land Verify test in the FMS CDU MAINT page and upgrade without a practice autoland. So, yes, a Cat 111 approach is sometimes carried out in Cat 1 conditions. Rest assured that when I take the engineers in the sim, I do the approach in cat 111 conditions to demonstrate how good the autoland is. I hope this helps.
@@tekavia another successful troll.
the sound of the trim 😭😭😭
Just make sure that you turn off MCAS...
That’s not 737MAX. Also it’s just a simulator
Anyone can push buttons. Hand flying a CAT III in real WX using a HUD to 700 RVR is profoundly rewarding. I used to marvel that I alone was flying the aircraft with HUD guidance and my partner backing me up on the gauges said they never deviated from dead-on until we crossed the runway threshold. Incredible technology. No autoland. We flew all the way to touchdown. A 300 RVR takeoff on the HUD was equally amazing. You could barely see half a stripe of the centerline ahead of you.
Wow, you are an amazing pilot! I am sure no one could do that kind of flying.
Where is the cat then?
It's just a simulation, training.
Nice sim. FS 2020, right? 🤣🤣🤣🤣🤣
Cat III but clear, calm day outside! I mean wtf dude! At least set the sim up so it reflects what you're doing !!!
As it says in the description, this video is made to instruct aircraft engineers in the classroom. We are only interested in how it works.
