Re: E2
Very good question. It's because the wings are heated using hot air from the engines. The problem is that when the engines are at idle (like they normally are in a descent) there's not enough bleed air coming from the engines to properly heat the wings. In order to provide enough hot air to keep the wings at a high enough temperature to prevent icing, we need to bump the thrust up a bit.
If you're flying a plane with autothrottles it will bump up the thrust automatically. So even though you're at "idle" it's a slightly higher idle. But the problem is that this new slightly higher idle changes your descent profile significantly. If you didn't plan the descent accordingly it can really throw it off.
Most jets allow you to tell the system that you're going to use anti-ice in the descent and it will plan the descent accordingly. But many times we don't expect to need it, but end up needing it.
In that scenario, with the added thrust that we didn't account for, we have two options. We can allow the plane to maintain the descent path (which will cause it to speed up) or we can use the speed brakes. That will allow us to maintain the descent path while not accelerating.

Re the 195 being slippery, the facts don't bear that out. Just looking at the manual for the E with the 777-300ER manual alongside, it looks like the Boeing needs another 35 miles to get down from 350 whilst descending at a speed 30 knots greater.
You could compare it to flying in props fine all the time on a turboprop, or lowering the gear 50 miles out. Technically allowed, but often the result of sloppy flying (depending on the plane).
As an AvCanada discussion grows longer:
-the probability of 'entitlement' being mentioned, approaches 1
-one will be accused of using bad airmanship

Edit; I have noticed on some flights as a passenger on jets that when the speed brakes are used it adds some excess noise
Re: E2
Coming off an airbus, I personally would take the bus any day of the week. From the comfort of the flight deck, to avionics, etc.
That said, the E2 is a very well designed aircraft that does the job well with it’s quirks.
1. Flight deck comfort. Sexual Harassment must be ok at Embraer, cause if your in the jump seat, you can definitely expect to get your leg rubbed a time or to. It is very tight when someone is in the jump.
2. Flight Deck seats. You’d think for a $100 million dollar airplane, one would not have to buy a $20 seat cushion from Amazon. No seriously, game changer for 5 hour legs.
3. Auto throttle, it is very lazy in the E2. Just slow to react, meaning you may need to override it.
4. Performance of the plane is fantastic, wing is very efficient and catches a lot of people off guard. She is slippery for sure, so just have to think well ahead of what you want it to do.
5. Avionics are very well thought out. User friendly for all and does not take very long to know what they are doing, when they are doing it, or why it’s doing it.

Re: E2
It does have Vertical-To.
Also, with a little planning and monitoring and possibly some light speed brake usage, it’s really not that crazy.
There’s many ways to skin a cat.
The issue arises when you plan for something then ATC switches it up. For example, if your descent is planned at 290 then during the descent they get you to slow to 250, the path you have in the FMS is designed for 290, it will be almost impossible without speed brake.
Another common thing is when you get turned tight and intercept from above, that can get dirty, but that’s what the gear is for I guess.

You’ll hear some pilots be negative about speed brakes, and on some types maybe that’s warranted. I’ve flown various narrow body and wide body jets, and it all comes down to what you’re in. For example, the 737Max has a hard time slowing and descending even for a jet. Combine that with a tail wind and a late descent clearance from ATC with waypoint crossing restrictions and you have no choice. A lot of times descending early to get into thicker air to slow (or level a bit sooner to slow then) isn’t an option due to the arrival. Wind, ATC and waypoint restrictions tend to dictate if you need them more than anything else.
The biggest thing is going slow and smooth on extension and retraction. Pilots yanking them out and slamming them back in make it a bumpy and uncomfortable ride. As someone else said already, they’re tools available to be used when necessary.

Re: E2
New E2 hire with a question. I've got my own set of black luggage coming from a previous employer (luggage linked below). Wondering if this would fit well in the E2 and if it would raise any eyebrows if I used my own that I know and like versus the issued stuff.
TIA!

Re: E2
Unless things have changed, they want you to use their own shitty luggage (some brand deal with Victorinox), and guys would get written up for even using their own lunch bag.SkyTruckDriver wrote: ↑Mon Sep 16, 2024 5:21 am New E2 hire with a question.

i did hear that they were short of luggage so they were letting people use their own. not sure if that's changed.

I use the Porter carry on but I absolutely refuse to use the briefcase. It ripped day one and it's just one big compartment. I hate it. I've been using my black Aerocoast bag since I finished LID. I love it.

does using a cushion make it comfortable enough? or is it still less than ideal.

Re: E2
The cushion helps. But it's still not great. Anything more than 3 hours in that seat and your tail bone is going to be sore.
Re: E2
I just shift the seat in different positions. It's no Airbus, but it ain't terrible. I've certainly operated in worse environments on longer legs than the E2 operates now - yes I have done the YUL-LAX.Speedbrakes wrote: ↑Tue Sep 24, 2024 11:09 am The cushion helps.

Padded bicycle shorts would work too if it didn't look like you were wearing a diaper under your uniform pants.
Re: E2
If you hear a complaint about the seat whilst in flight, ask your colleague if they have been shown how to adjust the vertical position of the back rest (as opposed to the vertical position of the seat). I've encountered people who have operated the airplane for two years and don't know about it. It makes a difference.

Because they learned how to fly it, but not the finer points of comfort. As I say that I realize people still struggle to fly an RNAV approach. Oy vey.
