FAA requires Boeing 777 software update to auto-throttle glitch

FAA requires Boeing 777 software update to auto-throttle glitch

The Boeing 777 software will be updated by the Federal Aviation Administration with a previous software update that fixes an issue with the aircraft’s auto-throttle system. An Asiana 777-200ER crashed in 2013, and the FAA reports that a proposed airworthiness directive (AD) was released on June 22.

The FAA wants to mandate that US airlines replace the outdated Airplane Information Management Block Point software on the 777s. According to the FAA, the most recent update also fixes a different problem with the 777’s “wing anti-ice valve.” The proposal by the FAA would apply to 353 777s with US registrations, including 777-200 and 777-300 models. An inquiry for comments was not immediately answered by Boeing. In July 2021, the airframer released a service bulletin and an existing software upgrade. The FAA wants to make that update mandatory.

According to the FAA, a number of problems led to this decision. It states that an analysis of fleet data found 50 instances of wing anti-ice valve failure between November 2013 and March 2019 in the period. The FAA claims that because of such failures, hot bleed air can harm wing slats. The valve’s performance is tracked by the upgraded software.

In the update, the auto-throttle issue is also addressed. This issue was made public following the troubling 777 incident. While the auto-throttle was in the idle position upon landing, a pilot started a go-around. The auto-throttle should be deactivated when the throttles are advanced, however this is not quite completed. Instead it returned the throttles to idle, “creating a go-around during a low-speed condition.

According to the FAA, investigators determined that the 777’s “insufficient low-speed protection” was to blame for the crash. This software update “inadvertently expected to fail [auto-throttle] go-around during manual throttle advancement after disconnect,” according to the FAA’s paper. The FAAs claim that Boeing’s most recent version fixes the problem.

American Airlines Letter Sparks Outrage Over Flight Attendant Salary

American Airlines Launches 8 New Winter Routes to Latin America &Caribbean

An employment letter from American Airlines (AAL) has ignited a firestorm of controversy across social media platforms, shedding light on the stark reality of flight attendant salaries in the aviation industry.

Shared on Reddit and authenticated by the union representing American Airlines employees, the letter has drawn widespread attention for its revelation of starting salaries barely surpassing federal poverty levels.

Detailing the compensation package for new flight attendants, the letter discloses an hourly rate of $30.35 per flight hour, translating to an annual salary projection of $27,315 before incentives and taxes. This figure, notably below the poverty threshold for both individual and two-person households in 2024, has sparked outrage and disbelief among readers.

What further compounds the issue is the disclosure that flight attendants typically work between 65 to 85 flight hours each month, supplemented by an additional 50 hours dedicated to aircraft preparation before takeoff and after landing—tasks for which they receive no compensation.

This revelation underscores the significant gap between the demanding workload of flight attendants and the meager financial rewards they receive in return. The letter, designed for use in dealings with landlords and other service providers as proof of income, closes with a plea for understanding: “any courtesy you can provide would be appreciated.”

This poignant appeal highlights the financial strain faced by many flight attendants who struggle to make ends meet on their current salaries. In response to these revelations, American Airlines flight attendants are mobilizing for action.

With negotiations underway for a new contract with the airline, which includes demands for higher pay, they are urging the White House to authorize their right to strike after a 30-day cooling-off period.
