Fernandes says the job is caretaker boss Ramsey's for the taking, even above his supposed "dream" candidate.
Ramsey took over the Barclays Premier League strugglers following the departure of Harry Redknapp this month and has now been appointed until the end of the season after talks with other parties yielded nothing.
Fernandes told Sky Sports News: "If someone keeps us up now we'd be nuts to change him.
"But even if we don't stay up, and we have to be real about it, I think Chris could still be the man that takes us to the promised land."
Prior to Ramsey's appointment for the rest of the season, Fernandes tweeted that he believed he had found his "dream manager".
Tim Sherwood - now at Aston Villa - and Michael Laudrup were both heavily linked with the Loftus Road post but nothing materialised
Fernandes said: "It wasn't a make-belief Tony Fernandes tweet
It was someone I was very keen on
Things conspired that in the end we felt we'd go with Chris."
He added: "We spoke to about five people and no one felt right at the time.
"One person did - and he's someone I still believe would be a dream manager for QPR - but when you've got someone like Chris Ramsey, I think the job is his for the taking."
QPR are 17th in the Premier League and outside the relegation zone only on goal difference but Ramsey oversaw their first away win of the season - at Sunderland - last week.
