Air Crash Investigation: Deadly Test

[NZ255]

[zk2704]

Really sure it was a 'Deadly Test', just watched it on YouTube and saw that water contamination in the Angle of Attack (AOA) sensors, causing them to freeze in flight caused the crash of flight 888T as the computers and controls didnt respond to the situation.

Interesting resolution at the end of the Film!

THE TRIM WHEEL!
The most important device in the Cockpit.

All of my manual flights are carried out with one hand on the Yoke/Joystick, and one hand on the Trim Wheel!

Adjust trim before take-off, trim for level flight, trim for landing, and ALWAYS re-adjust Trim Wheel whenever the Autopilot is disconnected, (either automatically, manually, or accidentally)!
It appears that the Pilot(s) failed to check this when the Aircraft was set from faulty Computer Control to Manual Control!
It was fully trimmed skywards, and if anyone had noticed, the aircraft was already far too low, and it was too late to correct the Trim manually!

Always keep a wary eye on the centre-marking on the Trim Wheel and make sure its not way adrift from the centre, either up or down!

A fascinating documentary, and an illustration on how easily things can go disastrously wrong in a highly complex, fully automated aircraft!

Paul.. I like ancient controls and gauges!... ...!

P.S..... I have fitted "Angle Of Attack" gauges in many of my regular GA aircraft to observe the effect! (There is a very nice analogue one in the Default FSX Learjet 45).

The first flight I ever did in a Tommy, my flight instructor said "Okay, this is the throttle, and this is the trim. The only time you need to touch the throttle is when you're taking off, landing, or manoeuvring. Other than that, keep your bloody hand on the trim."

Saying it soaked in is a bit of an understatement.

One of the most common "frighteners" on take-off!
Correct Trim, .....or lack of it!

You have entered the aircraft after the previous Pilot has been using the Autopilot, and you attempt to take off.....
(a) The aircraft accelerates but wont leave the ground!.... ....
(b) It leaves the ground, struggles skywards, and stalls!... ....

(a) The autopilot trim wheel was left with the nose pointing down!.... ....
(b) The autopilot trim wheel was left with the nose pointing up!.... ....

ALWAYS check the position of the trim wheel as soon as entering the aircraft....and trim correctly for Take Off (very slightly nose-high. There is normally a T/O mark on the trim wheel).

...and always reset the trim wheel during flight after switching the autopilot off!

Your flight instructor with keep a very careful watch on your use of the Trim Wheel!... ...!

Paul....Trim..... Short back and sides please!.... ...!
