A 15 kts headwind is a loss of 7.5 metres for each additional second airborne.

It is possible that the crew did deploy the RAT, and start the APU, as a last resort to deal with a totally unexplained event.

I wonder if they also switched the EEC controls to Alternate.

If stories dont have a clear and understandable end, as well as a beginning and a middle, well speculate endlessly about what the end might be.

Same principle applies to the Princess Di and Madelaine McCann stories, much to the delight of the editors of the Daily Express, Sun etc., as they can convert the great British publics yearning for cognitive closure into hard cash.

Only a matter of time before someone suggests that it was aliens, the Russians or that BA38 crossed a ley line at just the wrong moment.

They emit a radio frequency narrow beam signal of approximately 15Ghz in frequency at a peak radiated power of around 60 dBiW.

The licensing, placement and operation constraints of these vehicles is carefully set out in the above link and an area is defined which protects aircraft approaching and departing airfields.

BiW is one Million Watts worries me a little.

The logic which would result in both above happening automatically would be when all AC was lost to the aircraft, i.e.

Rather than be down to standby instruments, with the automation and advanced electronics available via the PFD the crew had speed vectors, instant display of min speed for flap setting right back to the stall which allowed them to get the very best out of this 200 ton idle powered glider.

How much worse depends on conditions, but IMHO having more energy isnt helpful if you havent reached the undershoot area, or a suitable place to try to land.

That energy, however, allows you to trade speed for that critical distance you may need.

Speed affects kinetic energy as a function of V22, whereas height affects your potential energy only in a linear fashion.

This means a 20 speed deficit robs you of 36 of your kinetic energy, whereas a 20 height deficit decreases the potential energy by the same 20.

In addition the higher glide speed at best LD decreases the time aloft, during which any headwind keeps pushing the airplane away from the field.

What is the amount of unusable fuel in each B777 wing tank Is this factored into the CFP I could never get a straight answer on this from my managers on the B767 so always loaded an extra 2000ks The B767 has 1000kg unusable fuel in each wing tank and this causes a Low fuel state Eicas message and requires a Low fuel state drill to be actioned..thus I was never happy to accept a B767 CFP with this 2000kgs as 30mins fuel remaining on landing at the closest diversion airport.

If I were a betting man my money would be fuel contamination.
