Xyoo pua 20 yog xyoo pua ntawm kev txhim kho sai ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub. Ib qho ntawm cov cim tseem ceeb tshaj plaws yog lub ci ntsa iab ua tiav ntawm noob neej hauv kev ua dav hlau. Nyob rau lub xyoo pua 21st, aerospace tau qhia txoj kev txhim kho dav dua qub, thiab kev ua haujlwm siab los sis qib siab hauv qib siab aerospace tau dhau los ua ntau dua. Cov kev ua tau zoo ua tiav nyob rau hauv kev lag luam aerospace yog cais tsis tau los ntawm kev txhim kho thiab tawg ntawm cov cuab yeej technology aerospace. Cov ntaub ntawv yog qhov pib thiab dhau los ntawm cov khoom lag luam siab thiab kev lag luam, thiab rau qhov ntau yog qhov tsim nyog ua ntej rau cov khoom lag luam siab. Txoj kev loj hlob ntawm cov khoom siv aerospace tau ua lub zog txhawb thiab lav lub luag haujlwm rau cov cuab yeej technology aerospace; nyob rau hauv lem, txoj kev loj hlob xav tau ntawm aerospace technology tau zoo heev coj thiab txhawb txoj kev loj hlob ntawm aerospace cov ntaub ntawv. Nws tuaj yeem hais tias qhov kev nce qib ntawm cov khoom siv tau ua lub luag haujlwm txhawb nqa hauv kev txhim kho dav hlau.
Cov khoom hauv aviation tsis yog tsuas yog cov khoom ua tiav lav rau kev txhim kho thiab tsim cov khoom hauv aviation, tab sis kuj yog qhov thev naus laus zis los txhim kho cov khoom lag luam aviation. Cov ntaub ntawv tuav txoj haujlwm tseem ceeb tshaj plaws thiab lub luag haujlwm hauv kev tsim kho aviation kev lag luam thiab khoom lag luam aviation. Nyob rau lub xyoo pua 21st, cov khoom siv dav hlau tau tsim kho nyob rau hauv cov kev coj ua ntawm kev ua haujlwm siab, kev ua haujlwm siab, kev ua haujlwm ntau, kev koom ua ke ntawm cov qauv thiab kev ua haujlwm, sib xyaw ua ke, ntse, tsis tshua muaj nqi, thiab kev sib xyaw nrog ib puag ncig.
