10.1 Pre-Flight Safety Briefings & NITS Emergency Framework
Key Takeaways
- Nigerian Civil Aviation Regulations (Nig. CARs Part 8) mandate routine pre-flight safety briefings prior to taxi or takeoff covering seat belts, emergency exits, oxygen masks, life vests, smoking prohibitions, and portable electronic devices.
- The NITS framework is the standardized flight deck-to-cabin emergency briefing format: Nature of emergency, Intentions of the Captain, Time available until touchdown/ditching, and Special instructions.
- Planned emergency cabin preparation follows a strict 9-phase chronological sequence ending with a 'Cabin Ready' report to the flight deck and cabin crew entering jumpseat stations.
- Able-Bodied Passengers (ABPs) must be selected and briefed at each assigned exit during planned emergency preparation to assist crew or operate exits if crew members become incapacitated.
- Safety instruction cards in every seat pocket must be aircraft-type specific, highly pictorial, and verified by cabin crew during pre-flight checks.
Pre-Flight Safety Briefings & NITS Emergency Framework
Emergency cabin operations rely on rigorous standard operating procedures (SOPs), seamless communication between the flight deck and cabin crew, and clear safety instructions provided to passengers. Under the regulatory framework of the Nigerian Civil Aviation Authority (NCAA) and Nig. CARs Part 8 (Operations of Aircraft), cabin crew members are required to deliver comprehensive routine briefings, maintain pre-flight safety equipment readiness, and execute standardized emergency coordination protocols during critical flight phases.
Routine Pre-Flight Passenger Briefing Requirements
Before every commercial flight departure, cabin crew must deliver a mandatory pre-flight safety briefing to all passengers. Under Nig. CARs Part 8, this briefing must be conducted prior to taxi or immediately after engine start before takeoff. The briefing may be delivered via a manual demonstration by cabin crew using safety demonstration kits or via an approved audiovisual safety video system.
Mandatory Briefing Content Areas
| Briefing Item | Regulatory Requirement & Detailed Demonstration Content |
|---|---|
| Seat Belts | Instruction on how to fasten, tighten, and unfasten lap seat belts. Passengers must be instructed to keep seat belts fastened whenever seated, even when the 'Fasten Seat Belt' sign is turned off, to protect against unanticipated clear-air turbulence (CAT). |
| Emergency Exits | Identification of all emergency exit locations on the specific aircraft type. Crucial emphasis that the nearest exit may be located behind the passenger. Location and operation of emergency floor path proximity lighting (floor-track lights or glowing carpet strips). |
| Oxygen Masks | Operational demonstration of drop-down supplemental oxygen masks. Instructions to pull the mask firmly to initiate oxygen gas flow, place the cup over nose and mouth, secure the elastic headband, and secure one's own mask before assisting children or dependents. |
| Life Vests / Flotation | Location of life vests (under seats, between seats, or in overhead units depending on cabin layout). Demonstration of donning over the head, pulling waist straps tight, and the critical rule: NEVER inflate the vest inside the cabin—inflate only upon exiting the aircraft doorway via pull-toggles or oral inflation tubes. |
| No Smoking Policy | Strict prohibition of smoking throughout the cabin, galleys, and lavatories. Specific inclusion of electronic cigarettes (e-cigarettes, vapes). Highlight that tampering with, disabling, or destroying lavatory smoke detectors is a federal aviation offense under Nig. CARs. |
| Portable Electronic Devices (PEDs) | Policy governing cellular phones, laptops, and tablets. Small devices must be switched to 'Flight Mode' and held or stowed during taxi, takeoff, and landing. Large laptops must be stowed in overhead bins or approved seat-pocket locations. |
Passenger Safety Instruction Cards
In addition to oral or visual demonstrations, Nig. CARs require that a Passenger Safety Instruction Card be located in every seat pocket and be visible and accessible to each passenger. Safety cards must meet strict design standards:
- Aircraft-Type Specific: Safety cards must correspond precisely to the specific aircraft registration, series, and door/exit configuration (e.g., Boeing 737-800 vs. Embraer E195-E2). Cards from different aircraft types must never be interchanged.
- Pictorial Clarity: Instructions must rely primarily on clear, multi-color pictorial diagrams to transcend language barriers among passengers.
- Content Elements: Cards must illustrate seat belt operation, brace positions for forward and aft-facing seats, exit opening handles, slide deployment, overwing window removal, oxygen mask donning, life vest fitting, and exit routes.
- Pre-Flight Inspection: During pre-flight checks, cabin crew must physically inspect every seat pocket in their assigned zone to ensure a clean, undamaged, and correct safety card is present.
Flight Deck & Cabin Crew Emergency Coordination: The NITS Framework
When an abnormal or emergency situation develops in flight or on the ground, structured communication between the Captain (Pilot in Command) and the Senior Cabin Crew Member (SCCM / Purser) is paramount. To eliminate ambiguity, prevent miscommunication, and standardize emergency information transfer, commercial aviation utilizes the NITS Framework.
NITS Emergency Briefing Structure
When an emergency occurs, the Captain initiates an emergency interphone call (typically signaled by a high-low chime sequence or emergency interphone alert button). The SCCM enters the flight deck or takes the interphone handset with a notepad and receives the NITS briefing. The acronym NITS defines the mandatory sequence of information:
- N — Nature of the Emergency: What exact hazard or system failure has occurred? (e.g., severe engine fire on Engine #1, complete hydraulic System A failure, rapid cabin depressurization, uncontained cargo smoke, landing gear asymmetry, or forced ditching threat).
- I — Intentions of the Captain: What operational plan is the flight deck executing? (e.g., immediate emergency descent and divert to Lagos DNMM, returning to departure field, initiating a forced land landing, or conducting a planned ditching in ocean waters).
- T — Time Available: How many minutes remain until touchdown, impact, or ditching? (e.g., "We have 15 minutes of remaining flight time until touchdown." This dictates whether crew execute a Full Planned Cabin Preparation or an Abbreviated Preparation).
- S — Special Instructions / Suppress Warnings: What unique operational constraints apply? (e.g., "Do not open right-side exits due to engine fire," "Use overwing exits only," "Prepare ABPs for door opening," "Turn off main cabin lighting prior to touchdown," or "Suppress passenger panic by withholding full evacuation announcement until full stop.")

Synchronization & Verification
During the NITS briefing, the SCCM must repeat back the entire NITS message word-for-word to verify accuracy. Both the Captain and SCCM must synchronize their watches down to the exact second. This time synchronization ensures cabin crew complete all cabin preparation phases precisely before the aircraft reaches the final approach phase.
9-Phase Planned Emergency Cabin Preparation Protocol
When time permits (typically when Time Available is 10 minutes or greater), the SCCM and cabin crew execute a structured 9-phase planned cabin preparation protocol to maximize passenger survivability prior to touchdown.
| Phase | Operational Phase | Action Executed by Cabin Crew |
|---|---|---|
| 1 | Flight Deck NITS Briefing | SCCM receives NITS briefing, repeats it back, synchronizes time with Captain, and exits flight deck. |
| 2 | Cabin Crew Briefing | SCCM gathers all cabin crew at forward galley. Relays NITS briefing, assigns specific exit door stations, verifies ABP briefing duties, and sets timer. |
| 3 | Passenger Announcement (PA) | SCCM or Captain delivers standard emergency announcement via PA system. Cabin lights are set to FULL BRIGHT to maximize visibility during prep. |
| 4 | Galley & Cabin Secure | Crew turn off all galley electrical power switches (ovens, coffee makers, boilers). Lock all galley cart brakes, latch all storage containers, and lock galley curtains open. |
| 5 | Secure Personal Items & Demonstrate Brace | Crew instruct passengers to remove high heels, sharp jewelry, glasses, ties, pens, and false teeth (stowing them in hand luggage). Crew demonstrate passenger brace positions in cabin aisles. |
| 6 | Brief Able-Bodied Passengers (ABPs) | Crew select 2-3 ABPs per assigned exit door. Brief ABPs on exit window checking, door handle operation, slide manual handle pull, crowd control, and slide foot support. |
| 7 | Final Cabin Sweep & Belt Check | Crew perform physical check of passenger seat belts, seat backs upright, tray tables stowed, window shades OPEN, and lavatories locked empty. |
| 8 | Cabin Ready Signal | SCCM notifies flight deck via interphone call: "Cabin Prepared and Ready for Emergency Landing." SCCM dims cabin lighting (to MATCH external conditions). |
| 9 | Take Jumpseat & 30-Sec Silent Review | Cabin crew secure themselves into assigned jumpseats, tighten 4-point harnesses, assume crew brace position, and initiate 30-Second Silent Review until touchdown. |
Operational Scenario: Planned Land Emergency
During a flight from Abuja (DNAA) to Lagos (DNMM), the flight deck detects a major landing gear malfunction where the nose gear fails to extend. The Captain contacts the SCCM via emergency interphone: "NITS Briefing: Nature—Nose gear failure; Intentions—Land on Runway 18R at Lagos with foam carpet; Time—18 minutes remaining; Special Instructions—Prepare ABPs for overwing exits, keep passenger baggage in overhead bins, dim lights for night landing."
The SCCM repeats back the message, synchronizes watches (18:00 countdown), and calls crew to the forward galley. Crew complete all 9 cabin preparation phases within 14 minutes, briefing 6 ABPs at overwing exits and securing all galley power. At T-3 minutes, the SCCM calls the flight deck: "Cabin Ready." Crew take jumpseats and begin their 30-second silent review, ready to command immediate evacuation upon aircraft stop.
