I am departing from an airfield which is within the CTR of a nearby airport but outside tower operating hours. The chart doesn't specify this situation.

According to ICAO rules,

Am I allowed to take off or not?

EDIT: this is not an EASA or FAA specific question. Rather international, ICAO rules, but if there are different conventions it's also good to know.

    $\begingroup$ It would be helpful if you would add EASA tags, and/or mention the country in plain language. $\endgroup$ May 16 at 17:39

    $\begingroup$ Well, the answers might be though... You specified LESL, which when I looked it up is in Spain. But I see you have since deleted it. Really, valid answers will depend on the airspace classification and rules for the country you are in. I don't think there is a single answer that will cover every scenario, and your question was probably better before with a specific example. $\endgroup$ May 16 at 18:32

    $\begingroup$ Also, VFR or IFR? $\endgroup$ May 16 at 18:36

    $\begingroup$ Re "Yes, but my question is not EASA nor FAA specific."-- I don't think that's true. For example, I don't think the question is meaningful at all in the context of the US. I don't think the phrase "aerodrome inside of a CTR" has any meaning in that context. Of course, I may be wrong-- but I would hope the question would have some content that would educate me on the error of my ways if that were the case. Anyway I live in the US and have no idea what a "CTR" is. $\endgroup$ May 17 at 15:45

    $\begingroup$ Different countries have different ways of dealing with what happens with airspace outside ATS operating hours. It is impossible to answer this question without you specifying a jurisdiction $\endgroup$ May 17 at 16:30

In the United States, if you are VFR at an airport in Class G or E airspace, you may take off without needing clearance or permission from ATC.

Normally Class D airspace reverts to E or G outside of tower operating hours, therefore no communication with tower is required or even possible.
