A new report has emerged, revealing that aircraft manufacturer, Boeing Co, was aware of a fault on its 737 Max models long before the Lion Air and Ethiopian Airlines crashes that claimed the lives of many passengers and crew members.

Boeing‘s engineers are said to have identified a problem with one of the systems on the 737 Max, but chose to ignore it. In 2017, the 737 Max display system software did not correctly meet the AOA Disagree alert requirements. This discovery was made by Boeing engineers after 737 Max deliveries had already begun.

Also note that the alert system was not operable on all airplanes, and Boeing acknowledged this.

Why the alert system is not operable: According to a CNN report, he airlines need to purchase an additional, optional feature, known as the AOA indicator, for the AOA disagree alert to work.

It was reported that the AOA indicator lets pilots know if one of the AOA sensors is not working, while the disagree alert shows if the sensors contradict each other.

The role of the disagree alert system: While the alert system is not directly linked to the two crashes, the alert system could have played a role in alerting the pilots of both Lion Air and Ethiopian Airlines of any possible malfunctioning from other systems on the plane.

The pilots could have been informed of a sensor malfunctioning, as the preliminary investigations of both crashes suggested faulty data from a malfunctioning angle of attack (AOA) sensor triggered the aircraft’s anti-stall software, known as MCAS, which consequently pitched down the nose of the planes as pilots struggled for control.

The MCAS system was identified as the primary reason for the Ethiopian Airlines‘ crash, although investigations haven’t been concluded.

Ethiopian Airlines’ crash could have been preventedBoeing said the senior leadership of the company and the Federal Aviation Administration were only aware of the faulty system (MCAS) after the Lion Air crash. Yet, both parties did not intervene in the fleet’s operations until the Ethiopian Airlines crash in March 2019.

If the level of effort invested after the Ethiopian Airlines crash was the same after the Lion Air crash, perhaps Boeing‘s aircraft would have been grounded worldwide to detect the fault and fix the problem. Unfortunately, both Boeing and FAA didn’t interfere.

Why Boeing didn’t attend to detected fault: Boeing concluded that the alert function was not necessary for the safe operation of the air-plane. It did not, however, flight-test what would happen to the MCAS system if the single AOA sensor failed.

Boeing‘s engineers didn’t immediately fix the problem, stating that the then functionality of the plane was acceptable until the next planned display system software update.

“The existing functionality was acceptable until the alert and the indicator could be delinked in the next planned display system software update.”

Boeing‘s original software design was criticised by the company’s former engineers and aviation analysts, for relying on data from a single AOA sensor, claiming that those devices are vulnerable to defects.

All 737 Max models will now have an operable alert system, Boeing said, adding that it will also come with an optional angle of attack indicator. While customers with the already delivered 737 Max planes will be able to activate the alert.

“Boeing said it is issuing a display system software update “to implement the AOA Disagree alert as a standard, standalone feature before the MAX returns to service.

“When the MAX returns to service, all MAX production aircraft will have an activated and operable AOA Disagree alert and an optional angle of attack indicator.

“All customers with previously delivered MAX airplanes will have the ability to activate the AOA Disagree alert.”

UPDATE: President Trump has been sued by MIT, Harvard over foreign students ban

guidelines for foreign students returning to US schools

The Massachusetts Institute of Technology and Harvard University have sued President Donald Trump over a new policy that restricts foreign students, whose courseworks would be taught online, from entering/remaining in the USA.

According to the Wall Street Journal, the suit was filed today in the US District Court in Boston, Massachusetts. The suit alleges that the modifications that were made to the Student and Exchange Visitor Programme (SEVP) by the US Immigration and Customs Enforcement (ICE), came without warning.

The impromptu nature of the modifications, therefore, has left Harvard and MIT with no choice but to think it was “arbitrary and capricious”.

Recall that ICE had on Monday announced the eagerly awaited modifications ahead of foreign students’ return to US campuses for the autumn semester.

One aspect of the modified guidelines, which has thus far proven to be quite controversial, requires foreign students to remain in their home countries if their courses are going be taught online. Foreign students who are already in the US were also directed to leave the country if their courses are online-based.

Harvard University is one of the ivy league American schools that recently announced plans to teach their courseworks entirely online, due to the COVID-19 pandemic. Harvard’s plan is such that students living on campus and off campus would attend classes online. However, the reviewed SEVP guideline by ICE has disrupted that plan.

CNN International quoted Harvard University President, Larry Bacow, to have said:

“The order came down without notice—its cruelty surpassed only by its recklessness. It appears that it was designed purposefully to place pressure on colleges and universities to open their on-campus classrooms for in-person instruction this fall, without regard to concerns for the health and safety of students, instructors, and others.

“This comes at a time when the United States has been setting daily records for the number of new infections, with more than 300,000 new cases reported since July 1.”

Similarly, MIT’s president L. Rafael Reif, issued a strongly-worded statement condemning the development. According to him, ICE’s modified SEVP guidelines “disrupts our international students’ lives and jeopardizes their academic and research pursuits.”

He went further to write that MIT’s “international students now have many questions – about their visas, their health, their families and their ability to continue working toward an MIT degree. Unspoken, but unmistakable, is one more question: Am I welcome? At MIT, the answer, unequivocally, is yes.”

Note that this story matters because of its international ramifications. Harvard University alone has about 5,000 foreign students, some of whom are Nigerians. The revised guidelines by the US Immigration and Customs Enforcement is bound to disrupt these students autumn semester unless the US Government rescinds the directive.

Akinwunmi Adesina, Afdb, Africa’s GDP could fall by 3.4% in 2020 if COVID-19 continues – AFDB

The African Development Bank (AFDB) published its African Economic Outlook 20202 Supplement on Tuesday and warned that the continent’s GDP would fall by at least 1.7%, and if the coronavirus pandemic continues into the second half of 2020, it could contract up to 3.4%. 

“Real GDP in Africa is projected to contract by 1.7% in 2020, dropping by 5.6 percentage points from the January 2020 pre-COVID-19 projection of the virus, if the virus has a substantial impact but of short duration. If it continues beyond the first half of 2020, there would be a deeper GDP contraction in 20202 of 3.4% down by 7.3 percentage points from growth projected before the outbreak of COVID-19,” the bank said.

America announces modified guidelines for foreign students returning to its schools

As a student already enrolled in a US university or about to be enrolled, you should read this carefully.

guidelines for foreign students returning to US schools

The U.S Immigration and Customs Enforcement (ICE), on Monday announced a much-needed update regarding the guidelines for foreign students hoping to return to campuses for the autumn semester.

A statement published on ICE’s website clearly spelled out the guidelines. Unfortunately, for some of the foreign students, these guidelines might as well come across as confusing instead of straightforward/explanatory.

UBA ADS

Before we proceed to ICE’s modified guidelines, it is important to first note that some American universities have announced various modalities for class attendance amid the ravaging pandemic. For instance, while some schools said their classes can only be attended online, for now, others said they are committed to regular classroom settings, even as some others have plans to combine both face-to-face lecturing and online classes.

As a foreign student planning to return to school in the USA this autumn, the modality adopted by your school will simply determine how ICE’s new guidelines will affect you. Let us now examine the guidelines.

Modifications to ICE’s Student and Exchange Visitor Programme (SEVP)

Guidelines on online classes: ICE said that foreign students enrolled in American universities offering only online classes, will not be granted student’s visas to return to the country. Now, this is tricky because even though such students are permitted by the U.S Customs and Border Protection to enter the country, they will not just be granted their student visas by American consulates anywhere in the world. The implication of this, therefore, is that no foreign student is allowed to be in the USA while undertaking online classes offered by an American university.

GTBank 728 x 90

Foreign students who wish to return/remain in the USA during the autumn semester must ensure that their classes will not be taught online. If it so happens that a foreign student is enrolled in a school offering only online classes, such a student has the option of transferring to another school that is conducting face-to-face lecturing. Otherwise, the student should stay back in their home country and take the full course online.

Foreign students who are already in the country but enrolled in schools offering only online courses must also ensure that either switch to a different school with the face-to-face lecture option, or leave the country willing. Otherwise, such foreign students risk being deported.

“Nonimmigrant F-1 and M-1 students attending schools operating entirely online may not take a full online course load and remain in the United States. The U.S. Department of State will not issue visas to students enrolled in schools and/or programs that are fully online for the fall semester nor will U.S. Customs and Border Protection permit these students to enter the United States. Active students currently in the United States enrolled in such programs must depart the country or take other measures, such as transferring to a school with in-person instruction to remain in lawful status. If not, they may face immigration consequences including, but not limited to, the initiation of removal proceedings,” part of the guideline said.

 Guidelines on regular classes: The revised guideline specified that foreign students enrolled in American schools where classes are still taught face-to-face are required to be available on campus to attend classes during the autumn semester. Upon return to campus, such students are allowed to decide whether to combine both physical class attendance and online classes.

Other guidelines: Foreign students attending US schools that are combining online classes with physical lectures will not be allowed to only attend online lectures while on campus. Instead, they must attend both the online classes and face-to-face classes.

Some issues to consider

-It is obvious that ICE is trying to stop some foreign students from trooping to the USA when they can remotely receive lectures online. After all, this will help prevent further trans-border spread of COVID-19. However, online classes come special challenges, especially for students in foreign countries. The time difference is one of such challenges; what happens when an online class is holding by 12 noon at Harvard when a student somewhere in South East Asia supposed to be sleeping?

-For now, American consulates around the world have suspended visa issuance. This poses a serious challenge to foreign students who were just freshly admitted into American universities and will student visas before they can be on campus for the autumn semester. Now, the saddest part is that any student who does not resume along with the other students, will not be allowed to resume later.

-Meanwhile, Nigerian students hoping to return to the US for their studies would have to grapple with immigration uncertainties mentioned above, along with foreign exchange troubles. Recall that even though the Central Bank of Nigeria announced that it has resumed the sale of dollars to Nigerian students studying abroad, the exchange rate for naira against the dollar remains high. And this is a major challenge to any student who will need to pay the high tuition fees of American universities.
