Runway deceleration?
On EI A319 from LHR yesterday. Twice during take off roll the a/c decelarated briefly. We eventually took off normally albeit towards end of runway...
I'm curious as to what may have caused this?

Was the aircraft full? Either way it would be relatively light due to short sector length and operating off a very long runway so the power would have most likely been de-rated making the perception of acceleration changes greater.
Rest assured there would have been plenty of extra power available if required!

dochealth Thank you for giving such an opportunity for diversion from the main flight plan (terrible pun intended) please don't take it personally!
Further suggestions are welcome.

I'm not a pilot nor have a great understanding of a/c flight systems. I always presumed commercial jets had leavers, when pushed forward the thrust would increase. I never knew some AB models have accelerator/thrust pedals.
I have one concern about the thrust pedal, on a long flight does the pilot have to keep pressure on the pedal as one does when driving a car?
