Transonic flight occurs when some local airflow becomes supersonic while other regions remain subsonic.
Near Mach 1, local acceleration over the wing can create supersonic pockets and shocks before the whole aircraft reaches sonic speed. Shock waves add drag, move pressure distributions, and can separate the boundary layer.
Transonic design uses sweep, thin sections, area ruling, careful inlets, and control-system planning to delay or manage shock effects.
Reviews check drag rise, buffet margin, Mach tuck, shock-induced separation, control effectiveness, intake compatibility, and structural vibration.
Mach effects are not only about crossing Mach 1. Local flow can become supersonic below aircraft Mach 1.
Aircraft flight mechanics and rocket flight share the same foundation: force balance, moments, energy, mass properties, stability, compressibility, and trajectory control. The rocket pages use these principles during max-Q, staging, re-entry, landing, and orbital insertion.
