Unit 10 lesson 4 task 2

2.2Describe emergency situations that could occur on board an aircraft

Emergency procedures: 

on-board emergency situations 

eg decompression (slow, rapid), fire, smoke, 

severe turbulence, 

flight crew incapacitation, 

hijack, 

medical;

2.3/2.4/2.5/2.6 Fire on board

State the elements which must be present to sustain a fire (2.3) by explaining what a fire needs in order to burn. Fire traingle

Identify types of fire extinguisher and the types of fire they are suitable for fighting (2.4) by making a list of the different types of fire extinguishers and listing what types of fires they are used for.

Describe the purpose and basic principles of a smoke hood (2.5)

Describe the role of the cabin crew on board in fighting fires (2.6) by explaining what the crew does during a fire to handle and solve the situation.

Fire on board/ 2.3/2.4/2.5/2.6

Procedures in relation to fire and smoke: elements present to sustain a fire (oxygen, fuel, ignition);

types of fire extinguisher and use (BCF - suitable for all types of fires, water - suitable for fires involving solids, foam, CO², dry powder – suitable for fires involving liquids, dry powder – suitable for fires involving metals);

smoke hood operation; smoke hood purpose eg to provide oxygen, protection; page 25, 4.1

role of cabin crew (firefighter – first person on the scene, communicator – with flight deck, coordinator – crew, passengers and equipment, protect passengers)

Decompression 2.7/2.8/2.9

• Identify how to recognise the signs of slow decompression (2.7) by describing what happens in the cabin during slow decompression.
• 
  
• Identify how to recognise the signs of rapid decompression (2.8) by describing what happens in the cabin during rapid decompression.
  
• 
  
• Describe the crew responsibilities following a decompression (2.9) by explaining the process of what the crew does during a decompression situation.

Use all items of theUnit content 2.7/2.8/2.9

• Procedures in relation to decompression: signs of slow decompression eg gradual loss of cabin pressure, ears popping, feeling dizzy or faint, progressively tired, nausea, hypoxia, warning on flight deck;
• signs of rapid decompression eg loss of cabin pressure in 1-10 seconds, loud explosive noise, mist formation in cabin, drop down masks appear, hot liquids boil, carbonated liquid containers burst, need to breathe rapidly, pain in ears and sinuses, fainting and nausea, severe vibration of aircraft;
  
• crew responsibilities following decompression eg obtain oxygen, transfer to portable oxygen, check other crew and flight deck, post decompression PA announcements, administer first aid, switch off electrics, respond to NITS briefing

Turbulence 2.10/2.11

Read the pages of module 4.1 and use all items of the unit content of 2.10 and 2.11 to complete your description

Unit Content

Procedures in relation to turbulence: types (light, moderate, severe); signs of light turbulence eg liquids shaking but not spilling, slight rhythmic bumpiness; signs of moderate turbulence eg liquids splashing out of cups, difficulty in walking, unsecured items dislodged, rapid bumps and jolts, difficulty in working; signs of severe turbulence eg services impossible to deliver, items falling, walking impossible, violent shaking and tossing around of aircraft;

2.11 Describe the actions to be taken for different levels of turbulence

Unit Content

actions to be taken for light turbulence (passenger seat belts to be fastened and visually checked, secure galley items, inform passengers using PA system);

actions to be taken for moderate turbulence (stop cabin service, ensure galley and carts are secure, check passenger seat belts are fastened, crew to seats, passenger announcements over PA);

actions to be taken for severe turbulence (hot liquid containers on floor, brakes on carts and wedge between seats, all passengers to sit down and fasten seat belts, crew to take nearest seats, announcements over PA, report to flight deck via interphone)

2.12 Explain the main actions taken by the cabin crew during a flight crew incapacitation drill

Unit Content

Flight crew incapacitation drill: crew members remain on flight deck; if pilot is in control – NITS briefing; pilot incapacitated - ensure pilot cannot touch aircraft controls with hands or feet eg fasten harness and secure pilot’s arms, lock inertia harness, move seat back; administer first aid/oxygen and obtain Jeppesen manual; assist remaining flight crew members; use flight deck/pilot checklist if required.
