I'm confused. In the FPL copy we've seen in the media such as here (http://www.pprune.org/rumours-news/587574-jet-goes-down-its-way-medellin-colombia-30.html#post9598286) the cruising level is...

If there was a tailstrike, as some reports say, the aircraft may have lost pitch control, not good if they then went around. The tailplane may have got damaged if the airplane was not on the runway....

During normal conditions the DFDR is provided with attitude information from IRU 1 via the DCU 1. (from the interim report). IRU 1 also feeds PFD 1.

I wonder which IRU feeds the standby attitude...

Icarus,

It appears from media reports that this drone was fully licensed and operating accordingly. Still this near miss happened. This puts the incident into another, to me more severe, category than thrill...

Flightradar24 track indicates that BA2276 stopped approx 600 metres / 1800 ft from the start of the take-off run. Wonder what that suggests in terms of when the engine failure happened, and what...

Any clues so far as to why the RH engine failed? That still seems to be the trigger event starting the chain leading to this accident?

Another explanation is that when the elevator is in full-up position, the mass balance horns protrude from the shape quite prominently. The starboard side seems to look similar.

Just a question from a VFR pilot: It would seem that a safer reaction to overspeed would be to apply speedbrakes/reduce thrust, instead of raising the...

The Nyquist theorem says that with a sampling rate of F Hz you can faithfully reproduce signals with a frequency up to F/2 Hz. So for example a CD is sampled at 44 kHz and it reproduces...

Agree, very interesting. I did an energy management exercise and plugged in some numbers. They suggest that to bleed off the excess kinetic energy caused by a 50-knot airspeed increase due to the...

I tend to agree. Before the tail was recovered, there was an official statement that the rescuers first priority was finding the casualties, the second was the black boxes.

Disagree. With new tech we can help prevent the next airplane go missing and save its occupants. If we just shrug, we'll eventually get more of the same type of accident as this.



However, by...

ICAO Annex 13 prescribes that a preliminary report shall be issued within thirty...

AIS, MMSI, IMO

A few tidbits on this topic:

- AIS is not mandatory for ships less than 300 tons dw. Neither for military ships, I believe. So don't expect AIS from every rescue ship.

Turning off the transponder in-flight

I'm trying to sketch a workable technical solution that makes it all but impossible to go invisible the way MH370 did.

From the various comments, it's evident that there are indeed legal...

Re transponder turn off

You can track polar orbiters...
