简短问答
这类交通工具要看哪些本地机构或走廊规则？
先看本地视角中的型式认定、营运许可与枢纽——不要假定一份全球清单。
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the 48 types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
安全运行Cargo aircraft需要按相同顺序追踪能量、信息与机械流。
CBTC、ERS等通用缩写保留，并在上下文中解释。
原理
就Cargo aircraft而言，CG envelope
就Cargo aircraft而言，Forward/aft limits tighten with fuel burn; loadmasters plot MAC percent.
就Cargo aircraft而言，Volume vs weight
就Cargo aircraft而言，Light express freight cubes out before max payload; dense cargo hits MZFW first.
就Cargo aircraft而言，ULD contour
就Cargo aircraft而言，Pallet height maps must fit fuselage crown curvature on each type.
就Cargo aircraft而言，Reserve fuel policy
就Cargo aircraft而言，ETOPS and polar routes add contingency beyond pax equivalents.
就Cargo aircraft而言，Deck pressurization load
就Cargo aircraft而言，Main deck must carry floor flight loads plus nine-g forward restraint.

运行步骤
02 就Cargo aircraft而言，Load & lock
就Cargo aircraft而言，Power ULDs to locks; verify CG sheet and NOTOC with captain.
03 就Cargo aircraft而言，Preflight & taxi
就Cargo aircraft而言，Door seal checks, pressurization test, and heavy-weight takeoff briefing.
04 就Cargo aircraft而言，Cruise manage
就Cargo aircraft而言，Monitor fuel, ETAs, and temperature-controlled ULD power if fitted.
05 就Cargo aircraft而言，Descent & land
就Cargo aircraft而言，Plan overweight landing if alternate; 制动 cooling on short runways.
06 就Cargo aircraft而言，Unload & turn
就Cargo aircraft而言，Ground power, open doors, break down ULDs for connecting flights or trucks.
硬性极限
就Cargo aircraft而言，MZFW / MTOW
就Cargo aircraft而言，Structural weights cap fuel or payload—loadmasters cannot exceed certified sheet.
就Cargo aircraft而言，Dangerous goods limits
就Cargo aircraft而言，DG segregation and quantity caps are regulatory, not airline preference.
就Cargo aircraft而言，Outsize clearance
就Cargo aircraft而言，Nose-door loads need swing clearance and special ground equipment.
