The term "normal glideslope" can be replaced with phrases like "standard descent angle," "typical approach path," or "conventional glide slope." Another option might be to use descriptors like "standardized rate of descent" or "expected angle of descent." This term is often used in aviation to denote the ideal pathway for an aircraft during approach and landing, but it is also relevant in other fields where precision and consistency are important. Some synonyms that capture the same idea include "regular glide profile," "common descent trajectory," and "familiar angle of descent." The precise wording used may depend on the context and audience, but any of these synonyms should suffice for communicating the same basic concept.
