If it's the same as on our legacy 319/320 fleet then I agree. The 321 radar is really nice but it's a shame that DAL opted for an old type instead of the 350 radar. Surprisingly, even Spirit is getting their new planes with the 350 type.

Speed: autopilot disconnects, auto pitch trim stops, spoilers retracts, max angle of bank is 45 deg. and sidestick control switch from load factor demand to direct elevator control. (not quite the same as direct law as mentioned by 80ktsclamp).

Makes me wonder if whovever re-wrote the manual mixed up both reconfiguration laws.
All of what you said is correct but and ive got to find this more clearly but at low speeds pitch changes from load factor to AOA. I'll quote chapter and verse when I get to find it.

Btw. For all of you in the normal law crowd, i present for your drive to work, the a320 podcast:

A320 Podcast | Podcasts

Join Matt and Andy every week while they explain what the hell is going on with the airplane you're type rated for.

I got this pic from the hydraulics episode. A practical guide to understanding what you have. Just remember B G Y in alphabetical order then B and G run slats, G and Y flaps, G runs gear extensions, retraction and normal braking and Y is backup to the brakes. The rest you can see clearly on flight control page.



One of their early episodes is flight control laws btw. 40+ episodes.

As was the radar on the A319/320. Does the A350 have the latest and greatest multiscan or did DL forego that along with the HUDs and the really cool tail camera?

Here vol 2 27.20.4.

Under normal law, when the angle-of-attack becomes greater than αprot, the system switches elevator control from normal mode to a protection mode, in which the angle-of-attack is pro-portional to sidestick deflection. That is, in the αprot range, from α prot to αMAX, the sidestick commands αlpha directly.

However, the angle-of-attack will not exceed αMAX, even if the pilot gently pulls the sidestick all the way back. If the pilot releases the sidestick, the angle-of-at-tack returns to αprot and stays there.

And a YouTube video


80. Is that how 330 works as well? Figure they'd be the same. Direct alpha from aprot to amax.

Evidently we went cheap all over the jet because we are just cheap.

Yes that's what I wrote as well. This only happens in normal and not in alternate since V alpha Prot and V alpha max are replaced by VSW in alternate law.
All you get in alternate is audio stall warning and low speed stability (gentle nose down command). However the Airbus FCOM doesn't mention that you switch from load factor demand to direct stick to elevator relationship in alternate law.

I can't see how the 350 wouldn't have at least the previous gen. multiscan radar (the one we have on our 321's).
Tail camera was a must on the 340-600 (75 m. length) but I'm not sure it is on the 350-900. Probably on the 1000. Though it's pretty cool indeed.

Also, i’ve heard we are pressing bombardier to change the entire c series order to the 300.

is this or is this not the same lca that told you we would have a small ae yesterday?
