Lansdown acknowledges the results will leave City struggling to
meet the Financial Fair Play regulations,
with sanctions, which can include a transfer embargo, for non-compliance expected to come in to force at the start of the 2014-15 season.
By the 2015-16 season, losses at a Championship club can be no more than £5m, with a maximum of £3m funded by shareholders and clubs.
"It can't continue as you've got the restrictions of Financial Fair Play," Lansdown added. "It's a fine balance and it's working with what you've got. If you have to trade to get into a better position, you have to trade.
"We've already gone a long towards it. What we've done over the summer and what we're currently doing will go along way towards that."
Despite the club's losses Lansdown has promised funds for boss McInnes if he needs them in January when the transfer window reopens, with the side currently sat in the Championship relegation places.
"We don't put a set budget out, I don't think it does you any favours to do it but consistently as a football club and a board we back our managers and we'll do that as we usually do," he stated.
"There is a balance as there is probably a few players who want to move out at the same time but we'll look to get some fresh faces in to help us through."
