RE: Boeing 737 crashes..........why ?

You could just train crews to fly the aircraft the way it is but that would cost a lot of money if you have to train all your existing B737 crews to fly the MAX as well. All aircraft with underwing engines pitch up when power is added, some a lot more than others because the thrust vector is below the pitch axis. It is like pushing on a swing. MCAS doesn't do anything the pilots can't do themselves with the manual trim switches on the control wheels.

RE: Boeing 737 crashes..........why ?

It seems Boeing got into trouble by installing a system which would make the MAX mimic the characteristics of older 737's to avoid a separate type rating or simulator training. The MAX is in competition with the Airbus 320 Neo which does not require either of these. The Neo is a fly by wire design with a taller landing gear that didn't require repositioning the engines. There would have been a lot of pressure for the MAX to be the same. 5000 aircraft ordered, eight crews per aircraft with a four hour simulator session per crew to familiarize them with the differences would amount to a ton of simulator time and a lot of money. The MCAS system used in the military KC-46 uses both angle of attack sensors and can be overridden by simply pulling back on the control column, the system will also only activate once in a given situation instead of repeatedly trying to trim the stabilizer as soon as pilot inputs stop. Any of these functions in the MAX system would have likely prevented these crashes,

RE: Boeing 737 crashes..........why ?

MCAS works when the aircraft is being flown manually so the electric stabilizer trim would have to be deactivated completely. Apparently there are some differences in the way the cutout switches work on the MAX so I can’t be specific. The crews also could have done some.things differently but it seems they were dealing with a malfunction in a system they didn’t know about, or at least didn’t know enough about.

RE: Boeing 737 crashes..........why ?

There is no evidence the programming was anything other than what Boeing specified. It wasn't the programers who allowed the use of a single AOA vane without a warning system to advise pilots of a failure in a system they weren't even told was there. I'm a retired pilot with type ratings on several Boeings and all I can say about this situation is that it is very disappointing.

RE: Boeing 737 crashes..........why ?

Boeing considered MCAS part of the flight control system, and elected to not describe it in the flight manual or in training materials, based on the fundamental design philosophy of retaining commonality with the 737NG. The 1,600-page flight crew manual mentions the term MCAS once, in the glossary. Top Boeing officials believed MCAS operated way beyond normal flight envelope that it was unlikely to activate in normal flight.

RE: Boeing 737 crashes..........why ?

If it wasn't in the manuals, who and how was the emergency procedure written? And, how would you diagnose a MCAS problem if it malfunctions and no one knows it's there? How did American Airlines and Southwest Airlines know about prior to accepting the airplane? I don't believe that any Southwest 737 MAX didn't know about the MCAS prior to flying it. There was only an emergency checklist for a runaway stabilizer, there is no mention of an MCAS system. Ethiopian 302 Preliminary Report

RE: Boeing 737 crashes..........why ?

Back to the OP's question folks, which is: "Anyone else have info as to why the MCAS was added ?" Thanks. * At this time, IMO the MCAS was incorporated so that the MAX model would satisfy the FAA that it was OK for pilots with a 737 FAA type-rating would not be required to get an additional 737 type rating. Yup and apparently it wasn't even in the manuals, the pilots didn't know it was there. Instead of being a safety feature, MCAS turned out to be a booby trap.

RE: FCA To Merge With PSA

"They must have had the fastest wrecker in the race." Yup and goes to the fact that those who take racing heritage into their decision misplace that metric...unless they also drive like they are in a race condition of whichever race track/terrain Few realize that by the end of the race, win or lose, that vehicle has little left to make it to 100,000 miles or more... Peugeot won the Dakar several times, East African Safari five times, as well as world rally championships, several leMans wins including with diesels and held the Pikes Peak record until it was broken last year by the electric VW prototype.

RE: How does one charge a dual battery vehicle?

I've always connected my charger to the positive on one battery and the negative to a chassis ground. Been doing it for years with no issues.

would not be surprised to see Jeep spun off, but I don't know who would buy jeep brand. No the status quo will stay as Jeep is pretty profitable for FCA I agree, their business is building vehicles. Why would you sell off winners?

RE: FCA To Merge With PSA

Not the only European incursion into the North American Automotive Scene recently Navistar showed Scania Light Quarry Trucks to be used in the Canadian Mining Industry Navistar is relying a fair bit on Scania expertise. Just to remind you Scania and MAN do have an agenda to buy Navistar outright when Global conditions improve. https://i.postimg.cc/Bb3js1J9/Scania-Off-road-1024x768.jpg And Scania and MAN are part of Volkswagen Group.

RE: FCA To Merge With PSA

La Conner, a town 70 miles North of Seattle had a LeCar police car in it's day, which allowed crooks to get away on foot or in an auto.I remember them, they had only 3 lug nuts holding the wheel on. The person that owned it called it Lecrap. Where I worked another person owned a Peugeot that everyone called a Push-it because of it's reluctance to start. I had a Peugeot 504 wagon. Under powered but solid and very comfortable. Never had a problem starting it.

RE: General thoughts on Hybrids

One advantage to having an EV as a towd, it could be recharging itself as it was being towed.

RE: General thoughts on Hybrids

Still need distance with machines at the controls. 10-20ft spacing is incredibly close and gets most of the drafting effect. 4-5ft and the slightest mechanical discrepancy and you have a fender bender. Fender bender, yes. Take 2 cars, running 60 MPH, 5 feet apart, compared to 2 at same speed but 100 feet apart. If the first of each pair slams on the brakes for some reason. The first pair, no matter who is driving, is more likely to hit, but when they hit, one is doing 60, the other 59.5. That impact will hurt nobody (Of course, the stopping distance will increase until the 2nd is stopping itself) Now look at the other pair. In the time it takes for the 2nd to cover that 100 ft plus the distance the first car travels that first car can slow a lot. And, if a human is driving that 2nd car, the cars will hit before the 2nd driver hits the brakes. Want a experiment? Put you fist in front of your shoulder. Step up until toes, (Or in my case belly) touch the wall. Punch a hole in the wall. Now, step back about half the length of arm, try again. All assuming both drivers (or machines) will be able to maintain control of their vehicles in a 60 mph rear ender. Big assumption. Distance is safety.

RE: General thoughts on Hybrids

There are places where hybrids make more sense and they often aren't where you might expect. We were recently in Rome and on the way to the airport I got to talking cars with the cab driver. I asked him why we didn't see any electrics and he said everyone lives in apartments and parks on the street. Nowhere to charge them. That won't change unless they install charging points all over the city like parking meters. It can be as simple as that in some places.

RE: What air compressor do you carry?

I have a VIAR 400P, pricey for a 12V but really like it. Doesn't take up any room and airs my 5er and truck tires from 45 psi up to 80 psi no problem. I like the 12V because I can use either my truck or 5th batteries to run it. Not a toy though, very solid and it can draw up to 30 amps so it is a good idea to run your vehicle when you use it. The only draw backs are no tank and you can't regulate pressure. If you run it with the line blocked, it will blow the inline fuse.

RE: Lowering TV tire pressures

They recommend using those charts unless you want to blindly run what the manufacturer says that is a CYA for them. Do you seriously think vehicle manufactures don’t know about those charts and don’t use them as one of the criteria when selecting a tire and determining what pressures are optimum for that particular vehicle? Look at the door of a newer RAM SRW they call for 80psi rear. No one in their right mind would run 80 unloaded. The dash goes crazy if you lower the air on a 2500. 3500's you can lower without the nanny screaming at you. Of course they know about the charts! They base their psi's on them. Some times! On my DRW they are right on with 80/65psi for full axle ratings. 80 is correct loaded or unloaded. I use the charts to adjust the rears. I checked yesterday my front and rears both have 8/32" tread remaining. No rotation other than moving fronts side to side with same rotation. Mine calls for 75 loaded, 45 unloaded. I run 80 and 50.
