Bahrain CAA Cabin Crew cheat sheet

Cabin depressurisation: oxygen masks deploy automatically when cabin altitude exceeds approximately 14,000 ft; crew don masks first, then secure themselves before assisting others.

Time of useful consciousness at FL350 is roughly 30-60 seconds; at FL400 roughly 15-20 seconds, so mask donning precedes any other action.

Emergency evacuation command sequence: assess conditions, initiate evacuation call, assign crew to exits, command passengers ('unfasten seatbelts, get out'), then sweep cabin and exit.

Evacuation must be completed within 90 seconds using half the available exits under certification rules (CS-25/Part 25).

Brace positions differ: forward-facing crew use hands behind head, head against seatback; rear-facing crew brace against the seat back structure.

Rapid decompression signs: fogging, loud bang, temperature drop, ear discomfort; slow decompression may present only as ear popping and drowsiness.

Land evacuation commands include 'Evacuate, evacuate, evacuate' or 'Unfasten seatbelts, come this way'; slide use requires arms crossed, chin down, feet together.

Crew must know exit row limitations: no exit row seating for passengers requiring assistance, minors unaccompanied, or those with conditions preventing rapid exit.

Cabin altitude is normally maintained at or below 8,000 ft; pressure differential limits are aircraft-type specific and monitored via cabin pressure indicators.

Emergency lighting is powered by independent batteries, typically providing at least 10 minutes of illumination after loss of main power.

Portable oxygen bottles supply crew and passengers via continuous-flow or demand masks; check pressure gauge before and after use.

Passenger service units contain reading light, air vent, call button and oxygen mask door; crew pre-flight checks confirm mask door closed and PSU intact.

Slide/raft combinations serve as evacuation slides and life rafts; some slides are not certified as rafts and must not be used as such.

Fire extinguisher types in cabin: Halon (or halon replacement) for electrical and flammable liquid fires, water for paper/seat fires; CO2 not typically carried in cabin.

Cabin interphone and PA systems have emergency power backup; crew must know alternate communication if interphone fails.

Doors are armed/disarmed by crew; arming engages the slide mechanism, and cross-check by a second crew member is mandatory before departure.

Primary survey sequence: Danger, Response, Airway, Breathing, Circulation (DRABC); call for medical assistance and notify flight deck early.

Adult CPR: 30 compressions to 2 rescue breaths at 100-120 compressions per minute, depth 5-6 cm; use AED as soon as available.

Choking adult: encourage coughing; if ineffective, give up to 5 back blows then up to 5 abdominal thrusts, alternating.

Hypoxia signs include confusion, cyanosis, restlessness; administer supplemental oxygen and consider cabin altitude reduction.

Anaphylaxis: give adrenaline auto-injector if prescribed and available, administer oxygen, monitor airway; request priority landing.

Fainting: lie passenger flat and elevate legs; recover position if breathing; monitor and document.

Suspected stroke: use FAST (Face, Arms, Speech, Time); note symptom onset time as it determines treatment window.

Medical kit contents include first aid kits, emergency medical kits, and AEDs; universal precautions with gloves and barrier devices are mandatory.

Nine hazard classes: explosives, gases, flammable liquids, flammable solids, oxidisers, toxic/infectious, radioactive, corrosive, miscellaneous.

Lithium batteries: spare batteries must be carry-on only; devices with batteries must be protected against short circuit and damage.

Passenger limits: typically up to 2 spare lithium batteries 100-160 Wh with operator approval; batteries over 160 Wh are forbidden in carry-on.

E-cigarettes and vaping devices are carry-on only and must not be used or charged on board.

Fire involving lithium battery: use water or halon replacement to cool, then contain the device; do not use ice as sole suppression.

Dangerous goods in checked baggage are restricted; aerosols, matches, and lighters have specific allowances that vary by operator and state.

Hidden dangerous goods include items such as camping stoves, paint, and fireworks; crew must question passengers when suspicious.

Any dangerous goods incident must be reported to the flight deck and documented for the operator and authority.

Unruly passenger escalation levels: verbal warning, formal warning, restraint, and diversion, with documentation at each step.

Restraint devices must be used only when necessary to prevent injury or harm and must be removed before landing unless required by authorities.

Crew should use the 'assess, communicate, resolve' approach; involve flight deck for any threat to safety.

Suspicious item: do not touch; isolate the area, notify flight deck, and follow operator procedures; note time and location.

Cockpit door must remain locked during flight; access is controlled by flight crew and only for emergency or crew rotation.

Security search: crew should know pre-flight cabin search locations, including seat pockets, lavatories, and overhead bins.

Reporting: unruly incidents are documented and may be referred to destination authorities; crew statements may be required.

Threat levels: verbal threats, physical assault, and attempted cockpit intrusion require immediate flight deck notification.

Cabin crew certification requires completion of approved training and periodic recurrent training, typically annually.

Crew medical certificates: cabin crew must hold a valid medical certificate as required by the state; validity periods vary by age.

Fatigue management: flight time limitations and rest requirements apply to cabin crew under operator and state regulations.

Licensing authority in Bahrain is the Civil Aviation Affairs (CAA); crew must comply with Bahrain CAA regulations and operator manuals.

Duty time limits and minimum rest periods are defined in the operator's operations manual and state regulations.

Crew must carry required documents during duty: licence or certificate, medical certificate, and identification.

Records of training and checking must be retained and available for inspection by the authority.

Drug and alcohol rules: crew must not perform duties under the influence; testing may be required.

CRM core competencies: communication, teamwork, leadership, situational awareness, decision-making, and workload management.

Situational awareness loss signs include fixation, ambiguity, and failure to monitor; use cross-checks and verbal callouts.

Assertiveness: crew should speak up using clear, specific statements and escalate if not acknowledged.

Fatigue effects include slowed reaction, impaired judgement, and microsleeps; report fatigue and use rest strategies.

Error management: use briefings, checklists, and cross-monitoring to trap errors before they propagate.

Communication: use closed-loop communication, standard phraseology, and confirm understanding.

Authority gradient: high gradients reduce speaking up; flatten by inviting challenge and using names.

Stress and workload: prioritise tasks, delegate, and use available resources; recognise personal limits.

Boarding: verify passenger counts, seat assignments, and special assistance needs before departure.

Special categories: passengers requiring assistance, unaccompanied minors, and those with medical conditions require specific handling and briefing.

Service sequence: pre-departure, meal and beverage service, and arrival; crew should adapt to passenger needs and cultural expectations.

Complaint handling: listen, acknowledge, and resolve or escalate; document significant issues.

Safety briefing must be delivered before departure, including exit locations and seatbelt use.

Passenger behaviour: intoxicated or disruptive passengers should be managed per operator policy and may be denied boarding.

Communication: use clear announcements and provide information in required languages.

Service standards include grooming, uniform, and professional conduct as per operator manual.

Fire triangle: heat, fuel, oxygen; removal of any one extinguishes fire.

Firefighting sequence: identify source, use correct extinguisher, and maintain communication with flight deck.

Lithium battery fire: use water or halon replacement to cool and contain; monitor for re-ignition.

Evacuation drill: crew must demonstrate ability to open exits, command evacuation, and use slides within required time.

Survival: after ditching, use slide/raft, deploy survival kit, and follow survival priorities (protection, location, water, food).

Fire in lavatory: check waste bin, use extinguisher, and close door if safe.

Smoke management: use smoke goggles and PBE (protective breathing equipment) when available.

Evacuation commands: use standard commands and ensure exit area is clear before opening.

Hypoxia: reduced oxygen; signs include confusion, cyanosis, and euphoria; treat with oxygen and descent.

Decompression sickness: nitrogen bubbles; symptoms include joint pain and neurological signs; request medical evaluation.

Jet lag and circadian disruption: manage with rest, hydration, and light exposure.

Communicable disease: crew should follow operator procedures for infection control, including PPE and reporting.

Medical fitness: crew must report conditions or medications that may affect duty performance.

Food and water safety: crew should follow hygiene practices and report illness.

Fatigue: cumulative fatigue affects performance; use rest and report.

Vaccination requirements: crew should maintain required vaccinations per destination and operator policy.
