It appears as though they almost made it.
I guess that the cuse of what made both engines shit the bed simultaneously will come later.

COMMENT MODERATION IS IN EFFECT UFN. This means that if you are an insulting dick, nobody will ever see it.
How do you lose oil pressure in both engines simultaneously? Can't the Naples crowd afford a Gulfstream?

Is it me...
ReplyDeleteAfter reading the report...
Twin jet about 1800 pounds of fuel per hour (give or take)
takes on 2100 pounds (350 gallons) of fuel and flies from
Ohio to Florida.
My bet is unless they had at least 2000 pounds of fuel on board
before adding to it they didn't have enough for the flight.
Fuel exhaustion maybe.
Part two:
Both engines get an oil pressure failure alarm. It was found
with both throttles at idle cutoff.
That's good procedure to protect the engines from bearing failure
assuming you do not need some thrust. Keeping them at low thrust
might have gotten them need time and preserved altitude needed to
make the runway. If it was a oil system failure it would have
trashed the engines. If it were a false alarm they could debate
that later on the tarmac.
Last item from my bug smasher days. Never give up air speed or
altitude until landing on the runway is assured... lest the pilot
cooling fan stops (engine failure). That said..
They were at 2000ft and more than several miles from the airport at
low speed (for a jet). Glide distance optimal is less than 3 miles
at best glide speed and they had neither altitude or air speed to
waste. So at 1509.33 landing was the only option and picking the
spot was immediate as they made ground contact at 1511ish less than
2 minutes from first failure alarm. Estimated glide speed is about
120mph and SWAG on sink rate for that speed is north of 1000ft/min
so ground contact from any distance greater than maybe 3 miles
is assured. They glide well but not that far.
I await NTSBs conclusion. The engine alarms will be a factor.
Eck!
Fate is the Hunter. A movie so god awful that the author, Ernest K. Gann sued the movie studio to remove his name from it. One of the greatest aviation books ever.
ReplyDeleteI wonder what percentage of line pilots would credit that book (1961ish) with leading them to their careers?
Fallows: the throttles were pulled back over the stops to shutoff.....
