Flying into the Europe then your Aircraft should to be equipped with the latest ACAS

The Airborne Collision Avoidance System II (ACAS II) was introduced in order to reduce the risk of mid-air collisions or near mid-air collisions between aircraft.

What is ACAS ? 

The Airborne Collision Avoidance System II (ACAS II) was introduced in order to reduce the risk of mid-air collisions or near mid-air collisions between aircraft. It serves as a last-resort safety net irrespective of any separation standards. ACAS II is an aircraft system based on Secondary Surveillance Radar (SSR) transponder signals. ACAS II interrogates the Mode C and Mode S transponders of nearby aircraft (‘intruders’) and from the replies tracks their altitude and range and issues alerts to the pilots, as appropriate. Non-transponding aircraft are not detected.

Types of ACAS
  • ACAS I Gives Traffic Advisories (TAs) but does not recommend any manoeuvres.
  • ACAS II Gives Traffic Advisories (TAs) and Resolution Advisories (RAs) in the vertical sense (direction)
  • ACAS III Gives TAs and RAs in vertical and/or horizontal directions
How does it works ?

Air India’s B747 Makes Its Final Journey, Waving Farewell to Fans

Air India's B747 Makes Its Final Journey, Waving Farewell to Fans

In a poignant moment marking the end of an era in aviation history, Air India’s iconic Boeing 747 aircraft, affectionately known as the ‘Queen of the Skies,’ embarked on its ultimate journey from Mumbai’s international airport.

The departure, bound for Plainfield, USA, where it will undergo dismantling and part-stripping under the ownership of American AerSale, signals the closure of a storied chapter for the airline.

Once revered for transporting dignitaries ranging from prime ministers to presidents, the Boeing 747 has etched itself into aviation lore. Yet, as airlines worldwide pivot towards more contemporary and cost-effective aircraft, Air India’s decision to bid farewell to its remaining Boeing 747s reflects the pragmatic realities of today’s aviation landscape.

The sale of these majestic planes to AerSale represents a strategic move by Tata Group, Air India’s new custodian, towards optimizing operational efficiency and embracing modern industry standards. Out of the four aircraft sold, two will be repurposed into freighters, while the remaining pair will be meticulously disassembled to salvage valuable components.

The final flight from Mumbai witnessed a touching tribute as pilots performed a traditional ‘Wing Wave,’ symbolizing the conclusion of the Boeing 747‘s distinguished service with Air India. This poignant gesture encapsulates the deep sentiment attached to the aircraft’s departure and its significant contribution to the airline’s legacy.

As the Boeing 747 embarks on its journey to Plainfield, USA, nostalgia permeates the air, evoking memories of its maiden flight on March 22, 1971. Over five decades, Air India operated a total of 25 Boeing 747s, each leaving an indelible mark on the annals of aviation history.

FAA investigation: Passenger seated in Captain’s seat inside cockpit at cruising altitude

FAA investigation: Passenger seated in Captain's seat inside cockpit at cruising altitude

A viral video capturing a startling moment aboard a United Airlines charter flight from Denver to Toronto has triggered a federal investigation.

The footage, initially shared on social media by Hensley Meulens, the hitting coach for the Colorado Rockies baseball team, depicts a member of the coaching staff seated in one of the pilot seats while the aircraft was in mid-flight.

In his caption, Meulens expressed gratitude to the captain and first officer for allowing him this unusual experience. The video, filmed by another passenger, reveals the cockpit door open, and at one point, a third passenger briefly enters the flight deck. Alarmingly, during this time, the captain was absent from the cockpit.

Despite the flight being a private charter operated by United Airlines, company and Federal Aviation Administration (FAA) regulations strictly prohibit passengers from entering the cockpit during flight or leaving the flight deck unsecured.

United Airlines swiftly responded, expressing deep concern over the incident. A spokesperson emphasized that the video depicted an unauthorized person in the flight deck at cruising altitude with the autopilot engaged, constituting a clear violation of safety and operational policies.

The FAA confirmed that it is actively investigating the incident, highlighting that unauthorized access to the flight deck during flight is a violation of federal regulations. The agency assured that it is taking the matter seriously and will conduct a thorough examination to ensure compliance with aviation safety standards.
