Safety Review for the A320 NEO Cabin Crew

Welcome to the comprehensive refresher course on cabin‑crew safety procedures for the Airbus A320 NEO. This module is designed for flight attendants, safety officers, and anyone involved in cabin operations. It covers the most common emergency scenarios, the correct use of cabin equipment, and the specific actions required by Vietnam Airlines’ standard operating procedures.

1. Communication Between Cabin and Flight Deck

Effective communication is the backbone of any emergency response. On the A320 NEO, the CAPT switch on the cabin telephone has a single, well‑defined purpose.

• Correct use: Initiates a normal, non‑emergency call from the cabin to the flight deck.
• It is not a distress or emergency call. For urgent situations, crew members must use the dedicated emergency intercom or the crew call button located at each seat row.

Understanding this distinction prevents unnecessary alarm and ensures that the flight deck receives the appropriate level of information.

2. Recognising the Three‑Tone Cabin Alarm

During flight, a sequence of three high‑low tones may sound in the cabin. This is a flight‑deck‑initiated alert that requires immediate crew attention.

• Action: The nearest crew member should pick up the cabin telephone and contact the captain for details.
• Do not make announcements to passengers until the captain’s instructions are received.
• Maintain situational awareness and continue monitoring the cabin for any additional cues.

3. Infant Safety During Take‑off and Landing

Infants are often held on a caregiver’s lap during critical phases of flight. The A320 NEO safety belt system provides a specific method to secure both the adult and the child.

• First, fasten the adult’s seat belt normally.
• Then, thread the infant’s belt outside the adult’s belt, creating a double‑loop that secures the child without compromising the adult’s restraint.
• This configuration ensures that the infant’s belt does not interfere with the adult’s belt during a rapid deceleration.

Never rely solely on the adult’s hold; the belt must be engaged for every passenger, regardless of age.

4. Opening an Over‑Wing Emergency Exit

When a rapid evacuation over the wing is required, the crew must follow a precise sequence to avoid delays or equipment damage.

1. Remove the protective cap covering the handle.
2. Pull the upper handle downward to release the latch.
3. Push the door outward to open it fully.
4. Verify that the slide‑inflation hose (the "air‑pump" lever) is in the ready position.
5. Finally, pull the inflation lever to deploy the evacuation slide.

Skipping any step can prevent the slide from inflating or cause the door to jam, jeopardising the evacuation.

5. Securing the Lifeline for Water‑Landing Evacuations

In the unlikely event of a ditching, the crew must attach a lifeline ("dây bám") to the aircraft structure before the slide is deployed.

• The first attachment point is the upper rear corner of the over‑wing exit door. This location provides the strongest anchor and ensures the lifeline runs clear of the slide’s path.
• Subsequent attachment points are placed along the wing surface, following the airline’s checklist.

6. Evacuation Instructions for Passengers Exiting Over‑Wing

Clear, concise commands are essential when guiding passengers onto a life‑raft or inflatable slide.

• Instruct passengers to place their feet forward, walk forward, keep their life‑vest on, and swim toward the rescue raft.
• Avoid ambiguous phrases such as “jump and run” or “slide and run,” which can cause panic and loss of coordination.

7. Slide and Raft Configuration on the A320 NEO

The aircraft is equipped with a total of six evacuation slides, arranged as follows:

• Four dual‑lane slides located at the main cabin doors (two on each side).
• Two dual‑lane slides mounted on the over‑wing exits.

This configuration provides redundancy and ensures that, even if one side is compromised, passengers can still evacuate safely.

8. Pre‑flight Briefing for Passengers Near the Over‑Wing Exit

Vietnam Airlines requires crew members to give special attention to passengers seated adjacent to the over‑wing exits.

• Immediately after the passengers are seated, the crew must explain the safety card and verbally outline the exit procedure.
• Emphasise the importance of keeping the aisle clear, listening for crew commands, and being prepared to assist in an evacuation.
• This proactive briefing reduces confusion and speeds up the evacuation if an emergency occurs.

9. Summary Checklist for Cabin‑Crew Safety on the A320 NEO

Use the following quick‑reference checklist during pre‑flight and emergency situations:

• CAPT switch: Normal call only.
• Three‑tone alarm: Use nearest cabin phone to contact the captain.
• Infant belt: Adult belt first, infant belt outside.
• Over‑wing exit: Cap → upper handle ↓ → push door → check pump → pull pump.
• Lifeline attachment: Upper rear corner of the exit door.
• Evacuation command: Feet forward, walk forward, keep vest on, swim to raft.
• Slide layout: Four cabin‑door dual‑lane slides + two over‑wing dual‑lane slides.
• Passenger briefing: Safety card + exit procedure for seats near over‑wing doors.

Regularly reviewing these steps will keep you prepared, confident, and ready to protect every passenger on board.
