Apron teeb pom kev zoo qauv
Apron teeb pom kev zoo yog qhov tsim nyog ntawm lub tshav dav hlau niaj hnub teeb pom kev zoo. Lub teeb pom kev zoo apron zoo heev pab txhawb lub apron maneuverings rau aircraft pilots. Nws kuj tau nce kev nyab xeeb thiab ceev ntawm maneuverings, qhov zoo ntawm kev saib xyuas los ntawm kev pom kev zoo rau cov neeg ua haujlwm. Tag nrho cov no yog qhov tseem ceeb rau kev poob-kev nyab xeeb thiab txhim khu kev qha davhlau kev pabcuam.
Cov kev cai yooj yim rau lub teeb pom kev zoo tau teev tseg hauv International Civil Aviation Organization (ICAO) cov cai [1]. Raws li ICAO Riles lub apron txhais tau tias "chaw nyob rau hauv av aerodrome npaj kom haum rau lub dav hlau rau lub hom phiaj ntawm loading thiab unloading neeg nrog caij, mail thiab cargo; refueling; chaw nres tsheb los yog tu". Lub luag haujlwm tseem ceeb ntawm apron teeb pom kev zoo yog:
• pab tus tsav tsheb tavxij nws lub dav hlau mus rau hauv thiab tawm ntawm qhov chaw nres tsheb zaum kawg;
• muab lub teeb pom kev zoo rau kev pib thiab debarkation ntawm cov neeg caij tsheb, thauj khoom thiab thauj khoom thauj, refueling thiab ua lwm yam kev pabcuam apron;
• tswj kev ruaj ntseg ntawm tshav dav hlau.
Uniform illuminance ntawm pavement nyob rau hauv lub dav hlau sawv ntsug cheeb tsam (chaw nres tsheb) thiab glare txwv yog qhov tseem ceeb. Nws yog ib qho tsim nyog kom tau txais cov lus pom zoo hauv qab no ICAO:
• qhov nruab nrab kab rov tav illumination yuav tsum tsis pub tsawg tshaj 20 lx rau aircraft stands. Qhov sib piv ntawm qhov sib piv (qhov nruab nrab illuminance mus rau qhov tsawg kawg nkaus) yuav tsum tsis txhob ntau tshaj li 4: 1. Nruab nrab ntsug illuminance ntawm qhov siab ntawm 2 meters yuav tsum tsis pub tsawg tshaj 20 lx nyob rau hauv cov lus qhia;
• Txhawm rau kom tswj tau qhov pom kev pom tau zoo qhov nruab nrab kab rov tav illumination ntawm lub apron, tshwj tsis yog qhov kev pabcuam ua haujlwm, yuav tsum tsis pub tsawg dua 50% ntawm qhov nruab nrab kab rov tav illuminance ntawm lub dav hlau sawv ntsug, nyob rau hauv ib qho ratio ntawm 4: 1 ( nruab nrab mus rau qhov tsawg kawg nkaus). Qhov chaw nruab nrab ntawm lub dav hlau sawv ntsug thiab lub apron txwv (cov khoom siv, chaw nres tsheb, txoj kev pabcuam) yuav tsum tau teeb pom kev zoo rau qhov nruab nrab kab rov tav illumination ntawm 10 lx.
