Safe Take Off Distance???
I need your help for the definition of the "safe take off distance" term? I'm preparing myself for a job interview but I'm stumbling about this term/expression. 
Thank you very much for your help!

Never heard of it and nor has Google apart from a mention in a 2009 Qatar interview thread at Qatar First officer Interview [Archive] - PPRuNe Forums where no answer was given.
Try "Before the grass/sand" with a nod and a wink?

How about, "Safe Takeoff Distance is that distance required for takeoff that falls within the Balanced Field Length (Accelerate-Stop) calculations for the type, which take into consideration WAT limits, (Weight, Altitude, Temperature), runway gradient, wind and runway contamination" ?
You might be able to find something useful in the "Takeoff Safety Training Aid" put out by the FAA some time ago. Give it a few moments to download.
Hope I didn't ruin anyone's fun.
I liked the gear-removal prevention distance but perhaps your interviewer will like this one and hire you.

.. from the various comments, it follows that the answer is "it depends" .. as is so often the case.

No idea what you are talking about..
the video clip in PJ2's link features Ray Hanna in the cockpit and Alain de Cadenet (not at all a journalist as suggested) doing the commentary ...
Probably easier to get to

Safe Takeoff Distance?
Come on Chaps, experienced pilots all, how would you answer the question . .?
You know you would.
Also, under the same heading I am surprised the original poster could not have answered it him/herself, especially as s/he has got as far as the interview with a large airline.
Forget "definition" just answer the question.
Like it is TORR < TORA and/or gets you safely off the deck (as indicated on your charts/graph/bug card/weight/temp/altitude/power graphs, cards etc coupled with a an ATPL course costing a mere 20/30/40/50 and the rest,000s of pounds) and into the air without touching the stopway nor hitting the lights and climbing away clearing all OCL/OCH, with plenty of margin available requiring no special effort and undertaking to successfully comply with all your gradients and gross and net takeoff stuff and basically, having achieved a good result in Perf `A` then it should be a doddle.
All determined by your WAT calcs at the beginning of the flight, is the perf required ample, amply within TODA and TORA?
Y/N? If = Y then takeoff If = N then you cannot takeoff unless you unload something or somebody.
Additionally, one assumes the slope, surface length have all been taken into consideration also, along with the mere takeoff perf of the aircraft at this W.A.T?
So, obvious, methinks you are all thinking the same thang and wondering why the poor chap has simply no idea him/herself - that being the case then it is hardly likely that he is going to crack the interview, or am I being pessimistic?
