I’m grateful for this one, there’s a slew of “ReAl WoRlD PiLoTs” out there making content, but it’s the context and depth in your product that’s a testament to your professionalism and experience so thank you for taking the time to create content like this

Great video as always. Now I now why we don't use VNAV on departures. Always wondered. I would have loved the see the noise abatement procedure at Santa Ana California.

Fantastic video, thanks for this. A question on the use of Up speed until 3000’ above airport elevation: is this done by your operator for noise reasons, or to preserve windshear guidance? What are the pros and cons of doing this vs. accelerating straight to 250 kt? Thanks again.

What needs to be entered in FMC for these for acceleration, thrust reduction, cutback etc?

@ericweynands Жыл бұрын

Great vid! Just a heads up. There's also "Canada" in North America *cough cough* and we have virtually identical rules.

@jvu2ilj26 10 ай бұрын

If the airplane is in the auto-throttle mode and your are not in VNAV, how does the airplane know when to reduce thrust? Or if you do it manually, how can you do it if the AT is enganged? I don't understand that part...

@yanchenye Жыл бұрын

Thank you. You mentioned it's possible to use VNAV to fly NADP. How does VNAV differentiate NADP 1 or 2 if we put in acceleration AGL 3000? Anything else I need to set up?

@tomstravels520 10 ай бұрын

NADP 1 you have 1000 for THR RED and 3000 for ACC ALT. NADP just have 1000 for both. If you want to maintain the flaps up speed until 3000 for NADP 2 then you can enter the flaps up speed and 3000ft AGL as a restriction in the FMC CLB page with 250knots as the target speed. When you pass 10,000ft just press ECOn to go back to normal CLB speed

@Richard_McDonald_Woods Жыл бұрын

Hi Emi 🤔Are there any airports that have either no NADP required or NADP2 during daytime, and then NADP1 overnight?

@A330Driver Жыл бұрын

There are no airports without NADP requirements. But if none are stated you're expected to fly NADP2 in Europe and the US and NADP1 in most other parts of the world.

I'm having issues for pmdg nose wheel steering like it is sliding on an ice? and turning from corners during taxi is so hard. i even need to reduce speed 1-3 knots to safely turn and sometime I stop. do you know how to solve that issue? :(

@Groveish Жыл бұрын

Yes. Link your steering to rudder only(if you don't actually have a tiller in real life) and don't move the rudder all the way left or right if you're going above 5 knots. Move it to 70-80% left/right instead, then it will steer normally. Only use all the way if you're starting from standstill, or very low radius turns below 5 knots

How do I reliably find out which of the two an airport uses? In the Jepessen Charts that Navigraph offers you can find it in the Airport Briefing Charts Sometimes in the General Section, sometimes in the Departure Section but not always. And for U.S. Airports no such briefings are published. By the way, as someone who lives in Bonn, I can attest that the Noise Abatement Procedures at EDDK do diddly squat when the wind is from the South in the Aircraft start on 14L flying towards the west afterwards. I don't know how often I hear the freight planes at night roar above me, and think: "Why is this so loud?" It seems a conflation of issues: The 767 many of these operators use is too loud, the NADP is ineffective and ATC seems to allow deviation from the SID too often. I know the routes, I know how they should fly. If they would stick to the route they would not overfly my appartment. But they often do. Which only can happen when ATC allows shortcuts.

@ezi__ Жыл бұрын

I'm a LIDO baby and been forever since I used Jeppensen but I'm pretty sure theres aerodrome charts with general information including Take-off Minimas and such. Another way of looking up further proceedures and such is thru AIP of said country.

@doltBmB 9 ай бұрын

yeah it seems to me the spirit of these procedures is to allow the engines to throttle down for a while, but here the autopilot/FD simply takes the reduced acceleration and commands more climb, and even though he's flying by hand he still follows the FD, so the engines never throttle down making it totally useless, for the autothrottle to reduce both acceleration and climb rate have to be lowered at the same time

@flyboy747uk Жыл бұрын

What about if there are speed restrictions along the SID route and you can’t accelerate to 250Kts until well after 3000ft?

@A330Driver Жыл бұрын

Then you fly the speed restrictions. The same of course goes for flap retraction, if you're speed limited of course you can't retract the..

hi quick question : at what altitude do you engage cmd A ? Did you engage it at any point in the vid ?

@boeingvsairbus9372 Жыл бұрын

Minimum alt is 500 feet AGL. Below that it wont turn on.

@A330Driver Жыл бұрын

Minimum is 1000ft AAL. Technically you can engage it above the MUH, 158ft. However it's not certified to be used that low.

@homasas4837 Жыл бұрын

Did you engage the autopilot at any point in the video ? Is the auto throttle armed enough to trigger the speed command at 1500 ft ? Thanks

So is that fot this reason you never use VNAV on the departure.. :)

Ok but... What if the pilot does not comply with this procedure? Do you get fines then or what?

Yep and they can be pretty hefty at times. I've seen a crew getting a 30.000€ fine for using NADP2 instead of 1.

@ironlemon666 Жыл бұрын

Thanks for the informative video, as usual! I wonder how Airbus pilots handle this, though (eg. how reliable is the managed speed if you correctly program the thrust reduction altitudes) 🤔

@tomstravels520 Жыл бұрын

Airbus seems to accelerate slower so there is no need to maintain a flaps up speed. Never seen them do it

@boeingvsairbus9372 Жыл бұрын

Why did you not use VNAV? I use it and it does the same, just a bit unaccurate

@A330Driver Жыл бұрын

Because we don't use it in my airline. Try to program a correct NADP2 in VNAV, good luck ;-) Also you loose windshear guidance as soon as VNAV engages which is another point not to use it on takeoff.

@@A330Driver I mean, don't you just enter the thrust reduction, acceleration and the engine out acc? The rest is done by LNAV and VNAV or not? for example, at 1000 feet, my plane starts lowering nose and doing the speed up.

talking about both procedures before demonstrating it creates a lot of confusion about which procedure is being demonstrated, you should talk about one and then demonstrate it, then talk about the other and then demonstrate it, keeping them separate
