The other day our A320 when started the take off role Engine#1 was lagging behind. Stopped all parameters where checked power added to Flx, TOGA everything was normal then take off roll started again at 140 kts egnine# lost thrust.
the next day when a go-around was initiated engine# not producing thrust after 10 sec thrust lower than engine# 2. and on the ground no thrust increase. then for the ferry flight the engine was ok. Can it be the same TLA resolver problem. I mean the TRA. but for this we don't get any Ecam messages or chk amber message on ecam next to N1 or N2?
