# Aerospace Engineering: Drones and UAS, Launch Vehicles, Flight Test and Certification, and the Design Process > **Part 4 of 5** of the *Aerospace Engineering* reference (plugin `aerospace-engineering`), covering §11–§14. Sibling skills: `aero-aerodynamics-airfoils-and-compressible-flow` (§0–§4), `aero-performance-stability-and-propulsion` (§5–§7), `aero-structures-aeroelasticity-and-avionics` (§8–§10), `aero-reference` (§15–§20). Section numbers are shared across the set; a reference written as §N → `skill` points into that sibling skill. > > **Currency:** Aerodynamics, structures and flight mechanics are settled — Lanchester-Prandtl circulation theory, the Breguet range equation, von Karman. Two regulatory areas moved. See §16 → `aero-reference` for BVLOS drone rules and eVTOL certification. > **Scope.** Complements a rocket-science reference (propulsion physics, orbital > mechanics, reentry), a flight-software reference (avionics and DO-178C), and a > space-exploration reference. ⚠️ **This is vehicle engineering: how air vehicles and > launchers are actually designed.** > > **⚠️ GOTCHA** boxes mark misconceptions and killers — and aerospace has both in > quantity. > > **The three ideas that organize the field:** > 1. **⚠️ Lift comes from turning the flow, and the popular explanation is wrong.** > Newton's third law and circulation both describe it correctly; "equal transit time" > does not, and it's what most people were taught (§1.2 → `aero-aerodynamics-airfoils-
