Best you are going to get is Mach .925. Once you get closer to the speed of sound, the more resistance you get. Supersonic burns gas big time. You also have to go high. All of which burns fuel. Cost will keep the speed down, unless you have lots of money.
Yes it is. But that's my point, those Convair's cruising at Mach 0.9-0.92, while current Airliner cruising at Mach 0.8-0.85..
The fact is that Transonic/Supersonic travel is just not Economical enough, even more that there are no Supersonic Airliners, there are no Supersonic Transport Aircraft of any type including Buissness Jets, Military Transports, EW/Specialist Platforms(other than converted Combat Aircraft) despite all the advantages such a Platform would bring.
I don't think Airbus minds if it loses A319 customers. It's sold hardly any A319neo (double figures), but thousands of A320neo & A321neo. The economics of a shrunken A320neo don't appear to be very good, while the A220 is right for that size range. It dropped the A318 a few years ago.
Wouldn’t be surprised if they dropped the A319 as well and concentrated on the A220-300 as they are basically competing against each other.
Nor me. The only point to it I can see now is fleet commonality for A320/A321 operators, & given the few A319neo orders, that doesn't seem to be attracting customers.
I heard on the news here that Garuda is cancelling its 70 unit order for the new aircraft, is that report also there?
Jakarta Post on Monday 25th March 2019 Garuda to skip Boeing briefing on 737 Max first paragraph and the order was for 50, with one received and Garuda have sent Boeing a letter stating that they are cancelling the order for the remaining 49 aircraft.

You’ll note that there hasn’t been a US flagged 737-8 MAX, that has had trouble. There are three ways to shut the system off. In the US and other first tier countries, this is one of the things that they test in the simulator (twice a year for pilots). Third tier countries don’t have that luxury. You have, Ive heard, 40 seconds to shut it off it there is trouble. They will readjust the software, but frankly it just points out why not to ride in third tier operated planes.
That's a big call Art. There are a few so called first tier airlines around that I wouldn't touch with a 40 ft barge pole and that includes US as well as European airlines amongst others. Just because it's a US flagged airline doesn't make it any better than the rest.
Most planes have some items that require special attention. That’s why those who fly them get so much training. Airbus planes are generally not liked by pilots, because the computers have the final say as to what they will allow. Boeing has resisted that, but the MAX has substantial computer control. This “anti-stall programming” will fail on occasion, that’s what training is all about. Motors fail too, and pilots get training in how to deal with those failures. It would be interesting to get some commentary from a pilot checked out in the MAX to see their thoughts.
I’ve always heard it was the other way around. Mandatory use of the autopilot over 10k. Because it’s gets better mileage. Additionally, so I don’t think that they have to manually fly the plan at under 10k. They have to maintain Cat III currency, so pilots need to do an auto land (with autopilot) once a month. You know when it’s the computer flying because it feels like a carrier landing.
