So I came across this sentence and whats confusing to me is the infinitive in the beginning. I thought the construction was "be to do something" ( "...is to ban...). I have seen similar sentences in the past mostly in headlines so maybe words are left out because the meaning is clear as it is?
Heathrow to ban night flights as part of plan for third runway.
Heathrow will ban (is to ban or is going to ban) night flights as part of plan for third runway.
As you can see, not much space is saved if you compare the two sentences. However, using "to infinitive" is broadly used in headlines as it is concise and doesn't cause any confusion. It is a style that many news media use now.
In the body, the journalist writes
The president will announce his nominee to the Supreme Court at 11 a.m. ET Wednesday...
You will notice that the two sentences mean the same except that the latter has more details.
As @Era commented, the headline doesn't need to follow grammatical rules so strictly, especially the requirement to have a verb in a sentence. A verb could be omitted to save space.
