PIA A320 Crash Karachi
Parkfell
"ROD ? In reverse centre engine.."
The Trident could use reverse on the outer engines in flight. Although people speak nostalgically of RoDs of 12000+, clearly the risk of catching up the cabin had to be considered. However, it did make it easier to reduce speed and height simultaneously.
It has to be stressed that in a hot and high situation close to the airport, gradient is more important than losing height at high speeed.
As a corollary, in a visual circuit there is never any point in proceeding downwind at high speed past the airport.

When I first started with an Airline on the B737 it was a matter of pride to be able to keep the speed on till late as possible , flap on schedule and thrust up and stable at 500’. Easiest way to get down was 320 knots and speed brake. Then hold your nerve. As long as your below profile everything is sweet. Today impossible. 250 knots below 10,000 and other even more restrictive company limits killed it. Obvious advantage is no more pesky QAR squawks but major, major downside nobody under the age of 40 has any idea of what the aircraft can do. Maybe not an issue if all you want to do is keep line flying nice and simple but a real problem when a crew finds themselves outside the envelope. I’ve seen perfectly competent crew hit the tilt switch when taken outside their comfort zone. Not their faulty , they’ve just never been allowed to experience it. But thats the brave new world.......

Two crews can be in exactly the same position and the outcomes diametrically opposite.
I have noticed a big change over the last 30 years in how comfortable individuals are in the aircraft.
Personally, once the doors are closed I’m in my element. Love it. But I cant say the same of many of the younger generation.
Too much cookie-cutter training. Not enough flying the aircraft. Not enough passion for flying.

Airbus flight from Karachi to Le Bourget is en route. Presently over the med, expected to land at 1130Z. They have the cvr and dfdr on board. flight number is AIB1889. Read out is going to start tomorrow..

The puppy farms as commercial outfits are really only interested in one thing ~ profit.
The ability to pay through the bank of Mum & Dad is often the case. They think of it as gaining ‘Status’ in society.
Depends upon the culture. Back in the 1990s, BAeFC trained Cathay students from Hong Kong ethnic Chinese only. There was difficulty getting recruits from time to time, as the ‘status’ was regarded similar to that of a taxi or bus driver.
My view is that pilots are best able to choose prospective pilots, not HR, or ‘recruitment experts’.
There are a number of what appears to be innocent questions which in reality are the ‘under arm test’.
Mental arithmetic for a start.
Q.1 what is the square root of 81?
Q.2 what is the cube of 9?

Slowing an aircraft down - it is a matter of energy levels. High speed and high altitude aircraft possess an abundance of both Kinetic and Potential energy. As profile drag increases as the square of IAS, then increasing drag (Speedbrakes, etc) at high speed will destroy more energy than it will at lower speeds. Slowing the aircraft down and then using speed brakes will not have as much effect as using the speed brakes at high speed before reducing.
Ballpark mental arithmetic was necessary in the slide rule time, because it did not give you the decimal magnitude.
SA and having the „big“ picture or at least some idea to analyse a situation or measurement is difficult to teach. And still you learn every day something new.
But I don‘t think that the median intelligence deteriorated a lot. It is more the problem of your memory that glorifies the past.

So heavily dosed on medication? Now we’re getting into the realm of the absurd, or perhaps not, but this is Rumours & News, so let’s go one further and ask if, as with the case of the mysterious Malaysian pilot, they might not have spent lockdown playing games on a flight simulator. This could account for the matter-of-factness and lack of alarm in the quiet dreamy voice we hear on the recording.

That would result in a huge pilot shortage. Today you can be happy if those questions can be answered with the use of a pocket calculator.

My grandson is thinking of becoming a pilot and I am instilling in him the necessity to practice and practice and practice his mental arithmetic. If he makes any calculation using a calculator then he must do a mental gross error check. For instance when buying fuel in US Gallons and then converting to Litres/KG and Pounds it is all too easy to get the digit in the wrong place.

Fatigue
Regarding fatigue risk assessment, does anybody knows about this crew duty on that day, as well as previous ones. I'm talking not only about days before that but also the monthly roster, because due to shortened flights, being out of the flight deck for a long period can be an issue sometimes.

So you are told to descend to FL180 to be level 20 before **** . Are you saying that you would get a calculator out? Even programming the FMS takes time which could result in a late descent. A quick mental calculation while looking out of the cockpit; - do I need to go down now then start descent and programme FMS on the way down or; I do not need to descend now so programme FMS first.

Paper One of the Scottish SQA maths exams, for NAT5 (‘O’ level / GCSE) is without calculators.
Paper Two allows calculators.
The final comment probably three years ago, somewhat tongue in cheek(?), by the Chief Training Captain of a well known National Airline to a group of us MPL simulator instructors was
“if nothing else, at least make sure they know how to multiply and divide by three before they leave you.....”.
A quiet chuckle went around the room.

However, I am sure the investigators will give due consideration to the possibility it was a factor, and make appropriate recommendations.
