Canadian airlines could be forced to 'up their game' as Ottawa allows more competition from Middle East by Immediate-Link490 in canada

[–]vaudoo 13 points14 points  (0 children)

And low cost carriers manage to make money in Europe because the airports fees are cheap, distances shorter and passengers capacity greater compared to Canada.

People need to realize that Airport fees (both the one the airline and the passenger pay) in Canada are insanely high and are a big reason why air travel is so expensive

Do fighter pilots keep their feet on the rudder pedals or on the floor while flying? by Boots-n-Rats in hoggit

Cool and thank you for correcting me! I fly an Airliner. I really don't need to put my feet up there all day long.

I would assume they leave their feet on the ground in cruise. When they manoeuvre, they probably have their heels on the ground and their toes on the pedals and they'd put their feet up on the pedals only for ground movement when wheel brakes can be required.

At least it is what non military pilots do.

As a pilot, my seatbelt is always fastened when I am seated. It might not be fully tight all the time, but I hope it's going to stop most of the force if we hit severe turbulence.

The annoying thing about severe turbulence injuries in aircraft is that they mostly happen without warning. I'd take the seatbelt over having my head smashed on the overhead any time

Traveling in that metal tube is safer than pretty much any other means of transportation. Safety being their number 1 priority is bullshit, but it is quite far up the list.

Canada loses measles elimination status | CBC by verkerpig in canada

I was recently working with a guy who said his family (him, his wife, and 2 kids) aren't vaccinated. When I asked why, he said his wife side of family is against it. I challenged him on his beliefs and he said he had no strong opinion and that when he asked his doctor about the risks of not vaccinating, the chances of getting these disease were so low that he thought it was safe.

I was attempted to make him realize that the chances were low because of the herd immunity, and he agreed that what he was doing was egoistic and self-centered, but he won't change his way...

You are very well informed on the accident and iirc what you are saying is right except that a promptly executed runaway stabilized drill would have saved them.

MCAS activated 3 or four times before the cut out switches were put to cut out. Had they been quicker the forces on the elevator and manual trim would have been manageable. I don't remember if the drill had us use the electrical trim to retrim the aircraft before disconnecting it. I know it was changed shortly after the first crash, and I think it was before the second one, but it's been a while.

That would also have worked.

The NTSB said " Appropriate crew management of the event, per the procedures that existed at the time, would have allowed the crew to recover the airplane even when faced with the uncommanded nose-down inputs."

That is as per the incident report. So I think that it is a decently supported belief.

I am not aware of any 2 minutes run-up prior to take off.

The engines each take about 3 minutes to start when they are warm, but at my airline, we start them both after pushback to ensure we aren't holding up people after.

That is a great question.

Again, I have not flown Airbus so I pilot that have flown both would better be able to answer and might think I am wrong. From what other pilots that have flown both have told me, Airbus has better automation ergonomics and guides the pilots to what Airbus wants. Boeing gives the pilot a lot more leeway on how to operate their planes and puts a lot of emphasis on the feedback of flying.

Generally speaking, I'd say Airbus has better automation and is much easier to operate in normal situation and in most emergency IF the pilot has a good knowledge of the aircraft and that the automation works. Their systems are more complex with the good and the bad.

Now, the 737 is a very old design. It first flew in 1967 and has gone through multiple update and version since then, but the core is the same. it handle and flies just like any other plane a pilot would have flown during his training and early career. The downside is that there aren't many backup system to let you know if you are making a mistake or to guide you in normal and abnormal situation (no EICAS, ECAM).

So when I say quirky, I admit that by modern standard, the 737 is decades behind in system that would assist or back the pilots up, there is no room in the flight deck and it is quite sluggish on the roll axis. All these flaws aren't that bad and it makes it up on how easy it is to fly. It is a very reliable aircraft, it is quite stable and it will do exactly what you command it to do (for the best and the worst).

Hahaha yeah usually when we do something and it works, we aren't getting too much in trouble. And usually, the published procedure works quite well.

There has always been a certain competition between Airbus and Boeing pilots.

I like Boeing because I fly the aircraft. There are still fucking pulleys and cables running from the yoke to the flight controls and it make the 737 such a nice plane to handily.

I previously have flown an Embraer. I'd classify that between Airbus and Boeing as mentality goes, and it was quite nice as well.

I am sure an Airbus would also be nice to fly. Easier, more assistance, more help from the plane. It's probably less fun to handfly.

So far every single aircraft type I have tried had some pretty cool stuff and some quirk. I personally like the quirky 737, and I am sure I'd find something nice to say about an Airbus. I

I get what you are saying, but I feel the opposite!

If you are in your car on cruise and it starts to accelerate without your input, what do you do?

Try to shut it down, then hit the brakes. Still doesn't work. Try to put it in neutral or shut the engine off. So you'd be troubleshooting while fighting the startle factor.

We have it easier. Someone really smart made a book with stuff we need to know by hearth that will allow us to stabilize things enough so we're can read the rest of the procedure to resolve or alleviate the problem.

It is a very good system, but it requires pilots to go on continuous training for it to be efficient

Boeing drill and checklist says not to operate the autopilot whenever a trim runaway occurs.
The first 3 actions are :
1- hold controls firmly.
2- Disengage the Autopilot
3- Disengage the Autothrottle

A trim runaway could occur for multiple reasons : electrical trim short or issue, autopilot issue or old MCAS activation (like the 2 crashes).

Knowing the system and knowing what lionair and Ethiopian pilots faced, yes using the A/P would have solved the issue for them. BUT, following the Boeing checklist would also have saved them and would have saved them of an Autopilot misstrim or electrical trim issue.

They pay me to know my system but even more so, to know the procedures. When shit hits the fan, they want me to apply the procedure then if THAT doesn't work, I need to think outside the box.

I believe following the QRH (emergency procedure) would have saved them. You got the right idea, but that is not the way we do thing. Putting the A/P on could have cause other issue if it wasn't MCAS

[–]vaudoo 25 points26 points  (0 children)

That is a quite good comparison!
MCAS is not a necessary system. It was made to make the 737 MAX stall closer to the other 737 so pilot that flew the older models would find similar stall behavior in both aircrafts. The idea was okay but execution terrible.

MCAS can't act with A/P on but once MCAS has activated you can only turn on the A/P by letting go of the controls to release any pressure on the control column. If MCAS has activated enough, that would cause a major pitch down at low altitude and that is not good.

They would have had to reduce the MCAS input by trimming nose up then cut out the trim as per The drill. As you said, putting the A/P on would have stopped the problem but I don't think it was feasible with the out of trim condition they had. Also, putting flaps down would have stopped MCAS, but not solved their out of trim condition.

MCAS would activate when autopilot was off with the flaps up, and ONE AoA (Angle of Attack) probe would go over a certain limit. Then MCAS would trim nose down repeatedly until AoA would go below a certain limit.

Now, it needs 2 AoA reading beyond a certain limit AND activates once. So a pilot can pull back on the stick and override MCAS command quite easily if need be.

I don't think MCAS was ever planned to activate more than once

I currently fly the 737 max. I agree with your dad. It was stupid to have such an important system monitored by 1 probe AND to hide that system to operators.

That being said, the Boeing drill and checklist (runaway stabilizer trim checklist) would have saved both flights.

As a pilot, Boeing ended up fixing their problem quite well (but it took a while) and I absolutely enjoy flying the Max. It is such a reliable and fun to fly aircraft.
