Extremely safe. Firstly, your pilots will have access to much more detailed and real-time weather information than you can get. They want to get home safely as much as you do, and will not fly if it ...

Why force the nose of 737 Max down in the first place?

The main thing to avoid in aeroplane stability & control, is an aerodynamic nose up moment that is not commanded by the pilot. The uncommanded nose-up moment would not auto-stabilise, but rapidly ...

What exactly did this mechanic sabotage on the American Airlines 737, and how dangerous was it?

It's a serious crime, but what that guy did, only affecting one system out of three, would be unlikely to cause a crash if the pilots were half way reasonably competent. The take-off would be ...

Why didn’t Boeing ramp 737NG production back up in response to the 737 MAX groundings?

There are several reasons why. First, it takes an awfully long time to make that kind of switch. While one can switch an assembly line for a product, that works rather differently for (say) ...

No, it is perfectly normal to operate without any fuel in the center tank. Until your fuel load is over about 17,000 lbs, the center tank should be empty. That’s enough for about 2 hours of flying, ...

Is it true that different variants of the same model aircraft don't require pilot retraining?

It appears to depend on how much changed. You do have to have some training between models. The selling point was that an airline with 737 pilots could fly the MAX variant with minimal retraining "...
