### Matsin lokaci
Matsin lokaci yana faruwa lokacin da akwai iyakacin lokaci akan ayyuka ko ayyukan membobin ma'aikatan.

[ana binciken hujja] [citation need] Wannan yana sanya matsin lamba ga ma'aikatan jirgin su yi aiki na tsawon sa'o'i a kan jadawalin lokaci, wanda ke haifar da matsi na lokaci kuma yana sa kuskuren ɗan adam ya fi dacewa.  Christopher Wickens, tsohon shugaban Jami'ar Illinois Urbana-Champaign's Aviation Human Factors Division, ya sami dangantaka tsakanin lokacin amsawa da ƙimar kuskure: Da sauri matuƙin jirgin ya bincika sashin kayan aikin jirgin, ƙarancin fahimtarsa ko ta zai kasance.  James Reason, mai binciken kuskuren ɗan adam, ya gano cewa matsa lamba na lokaci yana ƙara yuwuwar kuskuren ɗan adam sau goma sha ɗaya.  

Dangane da samfurin bayanai daga Tsarin Rahoto na Tsaron Jiragen Sama (ASRS), tsantsawar jadawalin shine mafi yawan abin da ke haifar da matsi na lokaci,  da masu aiki da tsayayyen hanyoyin zirga-zirga (FBOs) sune na biyu mafi yawan abubuwan da ke haifar da damuwa na jirgin sama.  Rahoton ASRS ya nuna cewa hanyoyi daban-daban na matsin lamba na lokaci na iya haifar da amsawar sarkar, tare da ɗayan yana kaiwa zuwa wani.

Tushen matsin lokaci sun hada da: 

Time pressure is impossible to avoid entirely, and the goal of researchers is to minimize the resulting human error. Pilots should be careful when facing such pressure, and take time to prioritize and re-evaluate their performances.&#x5B;**&#x5D; Furthermore, use of checklists is highly recommended.

Ayyuka da yawa suna faruwa ne lokacin da yawan aikin ya wuce iyakar ikon aiki na matukin jirgi. Nazarin ya nuna cewa wannan shine mafi girman dalilin muhalli na damuwa na jirgin sama. Akwai kyakkyawar dangantaka tsakanin nauyin aiki da matakin damuwa. Dangane da tsarin aiki na Karasek, damuwa ta aiki ta haifar da aikin canji da sarrafa aiki. Yawancin lokaci, lokacin da matukan jirgi suka sami sabon aiki, suna farawa ta hanyar tashi da jiragen sama da ba a saba da su ba a lokutan da ba su dace ba, kuma waɗannan abubuwan biyu na iya haifar da damuwa. Bugu da ƙari, saboda mutane kaɗan ne ke aiki da dare, kowane mutum yana da alhakin ayyuka da yawa fiye da ma'aikacin rana. Abu na biyu na samfurin Karasek, kula da aiki, yana nufin alhakin yanke shawara na ma'aikata. Mafi girman wannan alhakin, mafi girman damuwa.

Wani binciken da Wickens, na Jami'ar Illinois, ya yi, ya gano cewa aikin aiki yana shafar wayar da kan jama'a, ƙwarewa mai mahimmanci wajen sarrafa jirgin sama ta hanyar sararin samaniya mai girma uku tare da haɗari. A lokacin jirgin, dole ne matukan jirgi su saka idanu da sarrafa masu canji shida. Uku daga cikinsu - yaw, farar, da mirgina - suna da alaƙa da matakai na jirgin sama kuma an san su da masu canji. Sauran uku - tsawo, matsayi, da karkatarwa na gefe - suna da alaƙa da hanyar jirgin sama an san su da masu canjin matsayi. Wickens ya ba da shawarar cewa saka idanu da sarrafa waɗannan masu canji yana haifar da aiki mai yawa wanda zai iya haifar da rashin sanin sararin samaniya.

Masana kimiyya sun fara ƙoƙarin rage kuskuren ɗan adam daga aiki ta hanyar haɓaka nuni na kayan aikin jirgin. Masu zanen Cockpit sun yi nazarin abubuwa biyu. Na farko, tsarin kayan aiki, yana nufin ko jirgin ya kamata ya bayyana ya juya yayin da bango ya kasance mai ɗorewa (exocentric) ko kuma bango ya kamata ya juya yayin cewa jirgin yana da ɗorewa.  Masu zanen sun kammala cewa, kodayake ƙwararrun matukan jirgi suna aiki daidai a kowane nau'in nuni, matukan jirage gabaɗaya suna aiki mafi kyau tare da nuni na waje.

Masu zanen sun gano cewa, duk da cewa nuni na 2-D yana rage rashin tabbas na bayanai saboda suna buƙatar aikin tunani na tsaye da na gefe don canza su zuwa hotuna na 3-D, nuni na 3-D yana ba da cikakken bayani ga matukan jirgi tare da ƙaramin aiki.

### Gajiya
Hukumar Tsaro ta Sufuri ta Kasa ta ba da shawarar cewa matukan jirgi su yi kuskuren yanke shawara da kuma dabarun idan sun kasance a farka na tsawon lokaci fiye da matsakaicin lokaci.

Nazarin ya nuna bambancin dangantaka tsakanin gajiya da iyawar jiki. Yayin da gajiya ke ƙaruwa, ƙarfin jiki yana raguwa, kamar yadda haƙuri da yardar rai ke yi. Rage motsawa bayan jirgin sama mai tsanani yana cutar da aikin matukin jirgi.

Wani binciken ya nuna irin wannan dangantaka tsakanin gajiya, aikin tunani, da aikin ɗan adam. An dauki matakai na ra'ayi, aiki, da kuma matakan ilimin halayyar mutum ga mahalarta takwas, masu shekaru 22 zuwa 36, a kan ayyuka masu rikitarwa guda uku bayan asarar barci na dare ɗaya. Bayanan sun ba da shawarar cewa yayin da ci gaba da farkawa ke ƙaruwa, lokacin amsawa mai sauƙi yana ƙaruwa, yana lalata shirye-shiryen masu aiki don ayyuka.

Idan aka ba da rikitarwa ayyukan da ke cikin jirgin sama, guje wa gajiya yana da ƙalubale. Koyaya, bincike ya nuna cewa dabarun tsarawa kafin da bayan zirga-zirga na iya inganta faɗakarwar matukin jirgi da amincin jirgin sama. Kwamitin Kungiyar Likitocin Kayan Kayan Kwarewar Kayan Kungiyar Kayan Kimiyyar Kayan Kyakkyawan Kayan Kwararrun Kwararrun ya ba da shawarar hypnotics da sauran abubuwa, wasu ba a tsara su ba, don kara ingancin barcin matukan jirgi kafin tashi. Rahoton kwamitin ya bayyana cewa Sojojin Sama na Amurka suna amfani da magungunan hypnotic, kamar su temazepam, Zolpidem, da Zaleplon, don wannan dalili. Koyaya, tunda magungunan hypnotic na iya haifar da rashin barci a lokacin farkawa, yana da mahimmanci a yi la'akari da maganin da aka ba shi, lokacin rana, da tsawon lokacin bacci. Hanyar da ba ta magani ba ta haɗa da ayyukan barci masu kyau, bacci, motsa jiki, da abinci mai gina jiki. Kwamitin ya ba da shawarar cewa ingancin bacci na iya zama da mahimmanci kamar yawan, kuma cewa yin bacci kafin sauyawar dare na iya kara aikin matukin jirgi. Bugu da kari, motsa jiki da abinci mai gina jiki suna taimaka wa matukan jirgi su kula da lafiyar jiki, wanda zai iya rage mummunan tasirin asarar bacci.

### Sauti
Dangane da bincike, bayyanar hayaniya na iya haifar da damuwa ta jiki da haɗarin kiwon lafiya na dogon lokaci  kamar raunin ji, fushi, da rikicewar bacci,  dukansu zasu iya rage aikin.

Rashin jin ba kawai hayaniya ba ne kawai ya haifar da shi yayin tashi, har ma da ayyukan nishaɗi kamar sauraron kiɗa. A cewar Ƙungiyar Ƙasashen Duniya don daidaitawa (IOS), sauti a ƙasa da decibel 70 ba zai haifar da raunin ji ga kashi 95 cikin dari na mutane ba. Koyaya, ƙofofin ƙididdigar lafiya sun bambanta bisa ga shekaru da sauran dalilai.

Har ila yau, hayaniya na iya samun tasirin zamantakewar al'umma na fushi. Wannan yana faruwa tsakanin 55 da 60 decibels ga kusan kashi 40 cikin 100 na ma'aikatan ofis.

Sakamakon na uku na hayaniya shine rikicewar bacci. Nau'o'in rikicewar bacci sun hada da:

### Yanayin zafi
Matsi da ke haifar da zafin jiki ana kiransa matsin zafi ruwa yawanci matukan jirgin sama na soja suna fuskantar shi. Kodayake jirgin sama na soja yana da Tsarin kula da muhalli, zafin jiki a cikin jirgin zai iya tashi da sauri fiye da digiri 10 na Celsius sama da zafin jiki na yanayi, kuma Sojojin Sama sun ba da shawarar cewa yana yiwuwa yanayin zafi ya wuce  ° C (113 ° F).  Lokacin da irin wannan yanayin zafi ya faru a cikin yanayin zafi, duka aikin tunani da na jiki zai lalace. Lokacin da jirgin sama ke aiki kusa da ƙasa a babban saurin iska, tasirin ya fi muni saboda dumama iska na saman jirgin sama.

Matsalar zafi kuma tana haifar da yanayin sanyi. Lokacin da matukan jirgin saman soja ke aiki a babban tsawo tare da saurin iska, zafin jiki a cikin jirgin ya faɗi. Wannan yana shafar lafiyar jiki da ingancin aiki. Bugu da kari, damuwa ta zafi tana ƙaruwa yayin da bambancin zafin jiki tsakanin filin jirgin sama mai tashi da tsawo na aiki ke ƙaruwa. Misali, idan matukin jirgi na soja ya hau daga filin jirgin sama na  ° C (113 ° F) zuwa -60 ° C (-76 ° F) tsawo mai aiki na ƙafa 40,000, saurin canji yana haifar da damuwa mai zafi kuma yana hana aikin matukin jirage.
