it sure as hell takes increased engine power to maintain that AOA increase

I said that they were not caught off guard so there should have been no reason to circle over the Black Sea to find out what to do. European airspace has now been closed for more than 2 hours which gave them (or tather QS ops) plenty of time to come up with a solution.

TVS4160 is not heading towards Tel Aviv. It is now circling near Malta.

Given that both planes are not descending, maybe QS is negotiating for a waiver but wants them to be near IST and MLA in case that it does not come forward.

Still flying circles at 34,000 feet near Istanbul.

Here is the question. I've posed this to three friends that are on Max fleets... "If this happened to you a week ago, would you be dead?" (2 captains, 1 F.O.) the answers ranged from "probably" to "yes"..... The most important question followed "have you reported this anonymously to at least your company?" Yes they have and to their national aviation authority.... We are in a period of public hysteria, but, us professionals are doing it right. If the media catches this, so be it, we ain't skygods no more.... Ask your friends the same question.

Hugs

The 737 incurs a pitch up moment with additional thrust because of engine placement and moment. Not because of “lift”. I’m glad you’re working on your multi engine ratings right now and went over vmc factors including accelerated induced flow.

One supposes if blame is pointed their way that they will pay compensation without admitted guilt. Big business. Our deaths get factored into the number crunches.
Perhaps, but one has to ponder that the inevitable class action arising from both crashes, along with the evaporation of sales, will certainly test the theory of “Too big to fail”.

QS 4160 seems to have made up its mind to go somewhere...

Strange to see those two aircraft holding at that level and at that time of night. Either more airspace has just denied them access or the company is asking them to divert or return to base. Feel for the pax!

Hopefully, somewhere with fuel! According to Planefinder, this aircraft has been airborne for something like 5 hours. It looks as if it may be heading for Tunis.

These two Smartwings are they hanging about long enough to declare a fuel emergency ?

I just grabbed that from the NG tech manual. I’m assuming that the MAX has them as well?
One big read button on the yoke that disables ALL automatic functions, including MCAS!

I don’t fly the 737, but the regional airliner I have flown for the last 20 years gives total control to the pilot once this button is pushed. Not even the yaw damper is retained. I mean Jesus H Christ! What the hell has happened to simple common sense in design?

The irony of some flights not being allowed into the airspace:

The minute they call a mayday they'll be given assistance and allowed in!

So, when it seems to be functioning fine they're told "Go away! You're not safe"
When they call a Mayday, "come on ahead into our country, we'll get some fire crew and ambulances"

The EASA ban appears only to work in parts. FlyDubai A6-FNC has departed Bucarest in the last couple of minutes.

excuse my ignorance but surely wouldn't it have been more sensible for the authorities to give a cut-off time of say, midnight tonight, instead of blanket bans everywhere? two aircraft have now spent hours more in the air than they needed to, no doubt inducing panic amongst the pax, being held then told to go elsewhere. QS4160 now landing Tunis and it looks like QS1201 enroute to Ankara, having held over the Black Sea. Knee jerk reactions when they have no actual factual data?

Why not say all aircraft once landed at destination have to be grounded? There was a max into MAN earlier today, AFTER the announcement.

there doesn't appear to be an issue with the landings, only the take off phase.

The aircraft holding at Malta seems to be landing in Tunisia.
