In some of the cases in Glenn’s correct answer, such as official communication by radio, I think dropping the ‘I’ could be standard with the goals of being clear and concise. In other cases like texting it can sound a bit less selfish to omit the ‘I’

I certainly am able to do that.

Yes, it is possible to use "am" without the pronoun "I" directly beside it in certain grammatical constructions. This typically occurs in questions or sentences where the subject is understood or implied. Here are a few examples: Question: "Are you coming to the party?" "Yes, I am." Statement: "I can't believe you're going!" "I am, and I'm looking forward to it." In these examples, the pronoun "I" is implied from the context, and "am" is used to indicate the present tense for the first person singular.

How will it look like? Give an example.
