飛機防疫改革 : 消毒後座椅會變色
在飛機上要保持政府明定的社交距離其實極具挑戰性，達美(Delta)、捷藍(JetBlue)和西南(Southwest)等航空公司目前採取的是梅花座位，好讓乘客之間留出更多空間。PriestmanGoode的建議是以排為單位交錯安排座位，除了可以有更寬的個人空間之外，家人或是親友也可以安排坐在一起。在每排座椅之間會安置從天花板延伸至座椅頂端的屏風隔板以提供額外的保護 ; 座椅本身不會有任何接縫，因此更容易清潔。
在Covid-19大流行期間，許多航空公司已取消或更改了機上點心和正餐的選擇。PriestmanGoode對此提供了另一種安全的供餐方式 : 能夠往返於餐車及座位的移動式托盤，讓乘客在每次用餐時使用到的都是乾淨消毒好的餐盤。
PriestmanGoode針對商務艙的吊艙亦提出了升級版防疫改革 : 每位商務艙旅客擁有個人專屬的吊艙，並配有個人高架隔間和用於存放物品的衣櫃，吊艙對外則設置窗簾以提供更多的保護。

From seats that change color when clean to staggered rows, here’s what airplane cabins could look like post-pandemic
With mandatory masks and empty middle seats, air travel certainly looks different during the Covid-19 pandemic. But London-based transportation design firm PriestmanGoode has taken it a step further, and re-imagined how airplane cabins could be outfitted to make the environment safer for passengers and crew.
While it’s unclear when or if these designs could be brought to life, here are models depicting PriestmanGoode’s proposed changes to economy cabins:
Maintaining six feet of distance from other people on an airplane is currently very challenging. Airlines such as Delta, JetBlue and Southwest have taken to temporarily blocking middle seats to allow for more space between passengers.
PriestmanGoode proposes staggering the rows of seats, so that people have more private space. This also allows people to sit with a group of two or three friends or family members, while steering clear of other parties on board. Between each row of seats, a screen divider would extend from the ceiling to the top of the seat for additional protection. Even the seats are constructed with no seams or cracks so they’re easier to clean.
Seat backs and tray tables have been completely overhauled by PriestmanGoode. Instead of built-in touchscreens for movies and in-flight announcements, this design includes attachments for passengers to prop up their own tablets and smartphones on the seat backs.
And instead of the usual pocket with magazines and brochures, the firm has opted to print safety information and in-flight announcements on the seat so there’s less material to touch and handle. Similar to the media display, passengers could use bungee cords to fasten their own bag, water bottle or personal items to the back of the seat.
Many airlines have removed or altered the snack and dining options during the pandemic.
PriestmanGoode has a different solution to safely serve food: removable tray tables that go straight from the service trolley, to the passenger, then back to the flight attendants to be cleaned. Rather than wiping down the tray table before eating, this would allow passengers to have a freshly disinfected dining surface each time they’re served.
One innovation that PriestmanGoode is touting is fabric that changes color after it’s been cleaned. According to a press release, the seat fabric is treated with “photochromic and thermochromic ink” that reacts to cleaning supplies to indicate that it’s been disinfected with heat and light. (Textiles can be treated with dyes that change color when they’re exposed to UV light or heat, although this specific application is new.) Once someone sits in the seat, the fabric changes color.
The design firm also proposes using far-UVC light to kill airborne germs and virus particles in the cabin. The lights would be blue during the UVC light cleaning process, then shift to warm yellow when complete.
(New research suggests that far-UVC light can kill small particles of viruses and bacteria on surfaces and in the air. A study out of Columbia University found that far-UVC light killed 99.99% of coronaviruses in air droplets. Experts say these lights could be useful in healthcare settings, but more studies need to be done on the long-term effects of far-UVC light exposure to make sure it’s safe.)
