Before each flight takes off, the aircraft undergoes pre-flight checks: the engines, hydraulic systems, avionics equipment, landing gears... 17 procedures, none omitted.
But what about the person who was controlling this aircraft?
Zero processing steps.
The pilot arrived at his post, signed in, and boarded the plane. No one checked whether his blood pressure was normal today, no one knew if he had insomnia last night, and no one confirmed whether his heart rate and blood oxygen were within the safe range.
An aircraft worth billions, along with hundreds of lives, is entrusted to a person whose "physical condition is unknown" - this is the biggest safety blind spot in the aviation industry.
The aircraft undergoes regular airworthiness inspections, but the pilots do not undergo "personality suitability checks". You wouldn't allow an un-inspected aircraft to take off, so why would you let an un-inspected pilot take up their duties?
Three major challenges that aviation enterprises cannot avoid
Challenge 1: Pilots "working while ill" cannot be identified. Pilots face high job pressure, irregular schedules, and cross-time zone flights, making them a high-risk group for cardiovascular and cerebrovascular diseases. However, due to professional pride and flight pressure, even if they feel unwell, they will choose to "put up with it". What does a single episode of high blood pressure-induced dizziness at an altitude of 10,000 meters mean? No need to explain further.
Problem 2: The health condition of flight attendants "depends entirely on their own efforts". Flight attendants stand for long periods, work in an environment with low pressure at high altitudes, and perform highly demanding service tasks. Their physical load is extremely heavy. However, the pre-flight briefing only checks their appearance and grooming, but not their physical condition. Once a flight attendant experiences a health issue during the flight, the emergency response capability will directly decline.
Problem 3: There is no early warning for "fatigued operation" among the maintenance personnel. The maintenance staff have to work under high-intensity conditions in the hot or cold environments on the apron for years, with frequent night shifts. The combination of fatigue and health issues is severe. Just one tremor or one episode of dizziness could lead to a missed tightening of a single bolt, with irreversible consequences.
Pre-employment health screening machine: 30 seconds, providing a "safety lock" for flights
The pre-job health screening machine is an intelligent health screening device deployed by aviation enterprises in the registration area for crew members. Before taking up their posts, pilots, flight attendants, and maintenance personnel swipe their cards to undergo screening for multiple indicators such as blood pressure, heart rate, blood oxygen, and electrocardiogram within 30 seconds.
If the indicators are normal, the green light will be given and the personnel can be released for duty. If the indicators are abnormal, the system will automatically issue an alert and suspend the personnel's eligibility for duty, and simultaneously send the information to the aviation doctor and the on-duty leader. The replacement process will be initiated.
There is no need for employees to take the initiative; the system will take care of it for you. This is the leap from "relying solely on self-discipline" to "guaranteed by the system".
Actual application scenarios
Scenario 1: Pilot · Pre-flight inspection
The captain of a certain airline completed the sign-in process and was tested through the pre-flight health detection machine. His blood pressure was 165/100 mmHg and his heart rate was abnormal. The system blocked his qualification for flight operations. The aviation doctor intervened for assessment and arranged for a replacement captain. The captain subsequently sought medical treatment and was diagnosed with stage two hypertension and received treatment. If he had flown that transoceanic flight on that day, a sudden risk occurred at 10,000 meters above the ground, and the consequences would have been unimaginable.
Scene 2: Flight Attendants · Pre-flight Screening
After a flight attendant completed four consecutive flights, the pre-shift health detection machine showed that her blood oxygen level was 91% and her heart rate was abnormally high. The system issued an alert, and the duty supervisor adjusted her flight schedule and suggested she take a rest. This prevented potential safety hazards that might have arisen due to physical exhaustion during the flight service.
Scene 3: Aircraft Maintenance Personnel · Pre-job Inspection
A maintenance staff member was on night duty for the fifth consecutive day. Before going on duty, he took a health check at the pre-shift health testing machine. His heart rate fluctuated abnormally and his blood oxygen level was low. The system determined that "he should not go on duty". The team leader arranged for a substitute. After the maintenance staff member sought medical treatment, it was discovered that he had arrhythmia. One test prevented possible operational errors and safety accidents.
Not only safety equipment, but also the "compliance moat" of the aviation industry
The aviation industry is one of the industries with the strictest global regulations. In the event of a flight accident caused by a crew member's health issue, airlines not only face huge compensation costs - but also face suspension of operations, license risks, and devastating blows to their brand.
The value of the pre-job health testing machine goes beyond merely "preventing one instance of starting work while sick". It also builds a complete compliance evidence chain for the enterprise, consisting of "testing, warning, intervention, and recording". Each testing record serves as irrefutable evidence that the enterprise has fulfilled its health protection obligations.
Furthermore, the continuously accumulated health data of the crew members can help airlines optimize their scheduling models, identify high-risk positions, and formulate scientific fatigue management plans - upgrading from "post-event accountability" to "pre-event risk control", and from "experience-based management" to "data-based management".
