Да, означает. Вот вкратце (https://www.bbc.com/news/world-europe-60576443):
"What are no-fly zones? A no-fly zone refers to any region of airspace where it has been established that certain aircraft cannot fly.
It can be used to protect sensitive areas, such as royal residences, or brought in temporarily over sporting events and large gatherings.
In a military context, a no-fly zone is designed to stop aircraft from entering banned airspace, usually to prevent attacks or surveillance.
It has to be enforced by military means.
That could be surveillance, pre-emptive strikes against defensive systems or bringing down aircraft which enter the restricted area.
A no-fly zone over Ukraine would mean that military forces - specifically Nato forces - would engage directly with any Russian planes spotted in those skies and shoot at them if necessary"
