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.

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.

Was it heavy? I'm no pilot, but just thought 155 knots for landing at flaps 40 seemed a little high for a 737.. :)

@tekavia 3 ай бұрын

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.

@aubreyburke6829 3 ай бұрын

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.

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 ?

@tekavia 2 ай бұрын

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.

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.

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.

@tekavia 3 ай бұрын

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.

Can those trim wheels be turned manually?

Yes there is a handle that is stowed on the trim wheel.

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 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.

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.

@tekavia 2 ай бұрын

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.

Yes but weather good so visual approach

@tekavia 2 ай бұрын

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.
