David Bernstein's successor officially began work on Saturday and gave Sky Sports News a brief summary of his major aims.
They include increasing participation and improving the results of England teams, while a tightening of the disciplinary procedures is also on the agenda.
Dyke said: "You can't just come in from outside and go 'bang', but I do think at some stage you've got to outline what you're trying to achieve.
"That seems the most important thing, and that's what I'll outline in the next few months. Then I'll have four years trying to do it.
"What is it the FA should be doing? Obviously you want the England team to be successful, and different levels of the England team to be successful.
"Two, you want as many people as possible to play the game and three - there's discipline.
"It's an area where the FA is always getting into problems, largely because you now examine incidents from 28 different cameras, so I think that makes refereeing pretty difficult."
A step forward
Already planned for next season is a change in the rule which prevents retrospective action being taken on incidents witnessed by the referee.
Wigan forward Callum McManaman's knee-high tackle on Newcastle's Massadio Haidara last season fell into that category, and the FA's director of governance Darren Bailey confirmed a similar incident during the new season will be looked at again.
He told Sky Sports News: "If those circumstances arise again, we will be able to take a look at those issues.
"We think that's a step forward, but we think it's a proportionate step forward. What we don't want to do is create the impression we'll be reviewing every incident every Monday.
"We want the referees to make the calls on the day because the team that has been sinned against should have the benefit of any action on the day."
