Answer
The pilot should combine the layers instead of checking them one at a time in isolation. If any applicable layer prevents the planned operation, cannot be verified, or creates an unacceptable safety risk, the flight should be changed, delayed, or cancelled.
Explanation
Airspace decisions fail when pilots look for one green signal and ignore the rest. A legal and safe flight requires the combined picture: class of airspace, temporary notices, local zones, airport or heliport activity, sensitive sites, authorization conditions, and current traffic risk.
