Most of these aircraft are not under any kind of air traffic control.

The engine retrofit was not caused by regulations.

The cost of aircraft fuel has gone way up which restricts general aviation. And therefore reduces the chances of midair collisions.
I remember when aviation fuel was 16 cents a gallon. Is it legitimate to blame that increase in price on the government?
After all, don't you blame govt regulation on increased prices of things?

What??!!

If we depart Miami via commercial jet service to Chicago, who chooses altitude? Heading? Airspeed?

Is each pilot responsible to avoid other aircraft?

How DO they avoid mid air collisions?

Pitch is not angle of attack. Pitch is the angle of the aircraft relative to the ground. Angle of attack is the angle of the aircraft relative to the air striking the wing. You can be pointing almost straight up and have a low angle of attack (fighters do this...it's quite a ride!). You can have the nose pointed quite a ways down and have a high angle of attack.

Angle of attack is affected by the airspeed, and the effective loading on the wing. For example, a wing loaded to 2000lbs in level flight would experience an effective load of 4000lbs if you turn the aircraft in level flight a bank angle of just 30 deg. You feel heavier. The wing must carry that additional load.

Just like you get thrown to one side in a corner while in a car. The only difference is that an aircraft must bank first, then 'lift' the airplane around the turn. If you drove your car at speed through a banked turn on a race track, you will feel heavier in just the same way.

All wings have an angle of attack that is positive. Up to about 20 deg, the airflow over the wing is relatively smooth. Plow the wing at a higher angle of attack, such as by slowing the wing down or placing a heavier effective load on it, and the airflow breaks away from the wing in turbulent swirls (like the difference between a piece of plywood edge on into the wind, and held vertically against the wind). In that case, the wing cannot hold up the weight of the aircraft anymore, it's not flying anymore, and it becomes like a rock (ok, a streamlined rock). It falls. This is the stall.

To correct the stall, get the wing back up to speed again, and get the excessive effective load off of it (get out of the turn!). In other words, stop hauling back on the stick.

Trim systems (when they screw up) can command pulling back on the stick to induce a stall. The correction is to shove the stick forward. You are fighting the bad trim setting at this point, and it requires continuous pressure to keep that stick forward, but that's it. Of course, you get tired after awhile. Fortunately, you have a handy copilot to give you a rest. You just take turns holding that pressure. Then land the airplane as soon as practical.

MCAS is a trim system.

Is it? The only reason to save fuel like this is to satisfy the Church of Green and the Church of Global Warming.

The difference in fuel savings between these two engines is really quite small.

So long as the airline can fly and still make money, the fuel savings are not all that important.

I think I'm getting it, thanks. I entirely misunderstood stall. I thought it had to do with too high of a rate of climb....is that also considered stall, or is that entirely different?

As the pitch increases (as happens with ascent) the force of lift (vertical force upward) generated by the wings decreases.

A stall is simply when the vertical force of lift is insufficient to support the weight of the aircraft, causing it to "drop" (as opposed to the pilot decreasing the lift in order to descend in a controlled manner).

An aircraft can stall simply by not having sufficient airspeed for the wings to generate sufficient lift. If you were to take pilot lessons part of your training would be to climb to a good altitude where you will slowly reduce your airspeed until the "stall" alarm sounds and then you start to drop ... so you get a "feel" for it. Then you'd do it while you're in a climb so you get a feel for that, etc...

OK, I need to clarify something. There are two components to vertical lift.

1) lift generated from the angle of attack PLUS
2) Trigonometry: the cosine of the wing's pitch angle multiplied by the force generated by the airflow

Why am I bothering mentioning this?

An aircraft can climb/ascend by increasing pitch (pointing more upward) which, yes, reduces the amount of vertical airflow lift but increases the lift from the angle of attack.

At a certain pitch, the lift generated from the angle of attack begins to decrease along with the lift generated from the airflow. Pitch upward too much and the aircraft will stall.

IBDM,
I think if you increase power enough, the vertical lift can stay the same while lift from AOA will increase or decrease depending on AOA. The AOA can stay the same but the a/c will ascend just because that is the direction of thrust.

Yes. I neglected the third component of lift coming from the engines. That was one of the differences between the old engines and the new ones. You are correct that this will, in turn, increase the lift generated from the angle of attack.

Yes, when a pilot wishes to climb, thrust is normally increased.

Everything has value, price is set by how much people are willing to spend, to obtain that item of value to them. The airline can make money, if they have no fuel to fly, so the fuel is of greater value. They can always share the cost of fuel with their customers. If ticket prices are too high, not as many people fly, airlines buy less fuel. Gas company doesn't make money sitting on their product, and will lower the price.

Unfortunately, the government wants to get in on the profits, and applies taxes, fees, regulations, and anything else they can think of to squeeze a few more dollars out of everyone's pocket. Those costs are shifted over to the customer, but if ticket prices are too high, fewer people fly. The airline can only reduce prices so much, before it's cutting into profit too deep, and operating costs. So, they file for bankruptcy, and the taxpayers get to pay to bail them out.

It's different, but you have it partly correct.

To climb, an aircraft must slow down, just like a roller coaster does when going uphill. Even with those powerful engines, it still happens. Then an aircraft slows down, its angle of attack increases. The wing has to plow through the air more to squash enough of it down to keep the aircraft in the air at the slower speed.

You you try to climb steeper than the engines can do, the aircraft will slow down to the point of the angle of attack increasing to that 20 deg I spoke of. You stall. This is called a full power stall.

Again, the recovery is the same. Get the stick forward. Stop hauling back on it.

MCAS, being part of the trim system of the aircraft, can make it feel like you are not hauling the stick back when in fact you are. It can fool a pilot that is not paying attention.

Even worse, when coupled with the autopilot (another robot), as is typically done by most pilots during climb out, the autopilot is easily fooled by the trim system (it is, after all, just a robot!).

If the pilots aren't paying attention, the aircraft will stall. Foreign pilots are told never to disengage the autopilot if at all possible. They are put in a trap by their own training. The hesitation caused by this is long enough to crash. The plane is already at low altitude (it's climbing out at this stage) and there is no time to hesitate.

Once in cruise, MCAS is no longer active. It only runs during climb out.

It's actually simpler than that. If the aircraft is flying too slowly, it stalls. Angle of attack is directly related to the speed of the wing and the weight it must carry. No other factors affect it.

Tell a wing to fly too slowly (pulling back on the stick tells a wing to fly slower), it stalls.
The position of the stick is a wing speed control. That is all it does, consistently, every time, all the time.

If you are flying fast while straight and level, and you pull back on the stick, the wing slows down by climbing, just like a roller coaster. If you take the engine out of the equation for a minute (a glider), once at the speed you set with the stick, the wing no longer climbs. You fly straight and level at the new slower speed.

Engines make planes go up. Only the engines. The position of a control stick does not make a plane go up.

If, and only if, the engines are powerful enough.

Airline engines are powerful, but not powerful enough to make the aircraft go straight up.

Some fighters can do that though.

They did not provide the sensor. They don't manufacture sensors. They are a repair shop. The Seattle Times, as usual, has it wrong again. If their repair certificate was indeed pulled, it may have been due to reasons completely unrelated to any sensor they repaired.

The part is what's known as remanufactured. It's calibration being wrong isn't acceptable. You sound as ignorant as any American.

ITN, this is sad. When it comes to Native Americans, white people can't be trusted. That's not racism. There is no Powhatan tribe today. Kind of why you don't like me. I'm white and I know what happened.

Hey, I like you. So you think it's because I don't believe you know what happened?
