Anna's inflight safety page



Welcome to my Inflight Safety page. Here you can learn how to increase your
awareness of inflight safety whenever you're on an aircraft. It's a fact
that those who know what to do in an emergency have a greater than average
chance of surviving a survivable accident. So why not help yourself by
reading on... 

Whether you're a frequent flyer, or board an aircraft once in a blue moon,
you should always take responsibility for your own safety. This means
taking the time to pay attention to the safety demonstration and to read
the safety instructions card, which you'll always find in your seat area.
Why is this so important? Because if you found yourself in an emergency,
relying on the crew telling you what to do may be leaving it too late.

Even if you may travel regularly, it doesn't mean that you don't need to
take heed of the information given to you during the pre-flight safety
demonstration - never be complacent. Every aircraft is different: emergency
exits are located in different places and operate differently. In a dark,
smoke-filled cabin, would you be able to find your way to your nearest exit
before smoke-inhalation caused you to pass out? It's happened to
well-travelled passengers in the past...with fatal results. 

-------------------------------------------------------------

My first recommendation to anyone travelling on an aircraft is to establish: 

•Where you're sitting in relation to your nearest exits; are there exits
 behind you which are nearer? How many seat-rows is it to your nearest exit? 

•How do those exits operate? The safety instructions card, will provide
 details of their operation; if in an accident the crew member was
 incapacitated, could you open the door yourself? Remember, not all
 doors open outwards, some open upwards or downwards. The emergency
 lights may have failed - you may be doing this in complete darkness. 

•Are there any self-help exits near you? These exits are usually overwing
 hatches and it is up to the passengers sitting adjacent to them to
 operate them in an emergency; they are quite heavy and cumbersome and
 have to be thrown out and forward - the evacuation path is off the
 rear of the wing. Because of this, there are rules governing what
 type of passenger may be seated there. They must not be: elderly,
 handicapped, pregnant, obese, a child or a deportee under escort.
 Handbaggage at these exits should be placed in the overhead locker;
 only very small items, unlikely to cause an obstruction in an accident,
 may be placed under the seat in front. 



As soon as the aircraft begins to move, an instruction is given over the
public address system to the crew to: 'arm doors' or 'set doors to
automatic'. What the crew are doing is placing the door into a special 
emergency-only mode. Should the door be subsequently opened, a chute 
will deploy and inflate. 


-------------------------------------------------------------

Preflight Safety Demonstration 

After the crew have armed their doors, they will begin the safety 
demonstration. Let's look at what they tell you and why. First they 
will point out the safety instruction card. It relies on symbols to 
explain various safety aspects specific to that aircraft, so it won't 
matter whether you speak the local language or not - you should be able 
to understand the information it contains. 

Next you will be given a demonstration of how the seatbelt operates. 
Statistics have shown that in accidents, many passengers have wasted 
time initially looking for the seatbelt catch somewhere at their side, 
because a car seatbelt is the one most people are used to. Even for those 
who are very familiar with aircraft seatbelts, there have been documented 
cases where passengers have delayed evacuating because the buckle had 
turned so that the catch was against their stomach. In the dark, they 
were unable to ascertain this - at this point, panic could easily set 
in if your life is in danger. It should be pointed out that for reasons 
of safety, the catch must be lifted greater than ninety degrees in order 
to unfasten. Releasing the seatbelt has to be a positive action. 



The crew will next point out all the exits on the aircraft. They do this, 
because in many accidents survivors, dazed and disorientated, have been 
known to head towards the exit they boarded the aircraft by, even if it 
is considerably further than their nearest exit. If you did this in a 
smoke-filled cabin, it could seriously decrease your chances of survival. 
Knowing where your nearest exit is and how it operates also helps to 
reduce the likelihood of suffering negative panic, or behavioural 
inaction. This usually occurs in sudden accidents on or near the ground 
where passengers remain in their seats, in shock. If you know where to 
go and how to get out, you are far less likely to be a victim of this 
phenomenon. It ought to be stressed at this point, that statistics of 
aircraft accidents over the past decade indicate that over 70% of 
accidents occur on take-off or landing - the most critical part of 
the flight. 


-------------------------------------------------------------

Brace Position 

The safety demonstration varies from airline to airline and so does 
the 'brace position'. This is the position you should adopt, should 
the aircraft have to make an emergency landing. In the UK, a new brace 
position was made law in 1994; that is to say that the Civil Aviation 
Authority (CAA) required all British civil airlines to illustrate this 
position both on safety videos and cards. 
If the aircraft is about to make an emergency landing, adopt the brace 
position, and stay there until the aircraft comes to a complete stop - 
there may be more than one jolt. The cabin crew should call you towards 
their doors, but if they don't, make your evacuation immediately if you 
believe it is a catastrophic (i.e. life-threatening) situation. However, 
even in an emergency, don't attempt to open aircraft doors while the 
aircraft is still moving or to evacuate until the engines have been 
shut down. This is highly dangerous and could result in the loss of life. 


-------------------------------------------------------------

Fire / Smoke 

Back to the safety demonstration and the crew will point out floor or 
seat-mounted emergency lighting. This low-level lighting automatically 
illuminates if the aircraft power fails. White lights indicate the escape 
path and either red lights or strobe lights indicate exits. 

If there is a fire on board, the crew have BCF (halon) fire extinguishers 
to fight it. Should the source remain unidentified or the fire become out 
of control, an immediate emergency descent will be made. If smoke invades 
the cabin, since it rises, it is best to put your head as low down as you 
can (get into something like the brace position). Use headrest covers, 
pillow cases, or any material to cover your mouth - it works better if 
it's wet and keep your eyes closed. Keep as low down as you can until 
the aircraft has landed. Remember to memorise the position of your nearest 
exit - how many seat rows will you have to crawl past to find it? 
Passengers in the front cabin of any 747, or the front half of a 
747-300/400 upper deck cabin will have to go back to locate their 
nearest exits - there are no exits forward from those seat positions. 
It is wise to remember that it is smoke inhalation, not burns, that 
causes most deaths in a fire. 


-------------------------------------------------------------

Decompression 

The next item on the safety demonstration agenda is the subject of 
decompression or depressurisation. If for any reason the pressurisation 
system fails, or a break occurs in the aircraft structure, the result 
will be a decompression. A slow decompression may occur where, for example, 
a door seal fails, resulting in a gradual rise in cabin altitude and a 
decrease in cabin temperature (the external temperature at cruising 
altitude is over minus fifty degrees Celsius). 
If a rapid decompression occurs, the sudden equalisation of air pressure 
causes the cabin air to condense, which results in a temporary misting 
effect. Gases in the body will vent, although a blocked nose from a cold 
or hay fever may prevent the ears from clearing, causing ear-ache and in 
severe cases, may result in perforated ear-drums. Any loose objects in 
the cabin will fly around and if there is a hole in the fuselage (for 
example a broken window), objects will initially be sucked towards it. 
This is one of the reasons why the crew, during the safety demonstration, 
suggest that you should keep your seatbelt fastened whenever in your seat 
(the other being an unexpected encounter with clear air turbulence, where 
aircraft have been known to drop hundreds of feet in seconds). Amongst 
those decompressions caused by failures in the fuselage, there are two 
catalogued in which passenger's lives were saved due to the 'Fasten 
Seatbelt' signs having been illuminated at the time. 
If the cabin altitude reaches 14,000ft., masks automatically drop, 
usually from compartments above your head. Often, the masks just dangle 
above the head initially, and it is the pulling action to make it reach 
your face which sets off the oxygen supply. In a rapid decompression, 
you may only have twenty seconds of useful consciousness (i.e. when you 
are still able to think clearly); you may remain conscious for some time 
after, but will be unable to think or co-ordinate properly. This is 
usually accompanied by a feeling of euphoria - a typical sign of 
oxygen starvation to the brain. If you are standing, sit down 
immediately, strap in and grab a mask. 
If the masks above you don't drop, there are spare masks at most other 
seat rows - grab one from an adjacent row, they will reach. There have 
been many cases of passengers failing to take a decompression seriously 
and not put on a mask, especially when it's a slow one, and have become 
quite severely hypoxic. 
The next thing that will become obvious in a decompression is the steep 
angle of the emergency descent that the flight crew will have instituted. 
They will be taking the aircraft down to a level at which it is possible 
to breathe without the need for emergency oxygen (usually 10,000ft or the 
minimum safe altitude, which is around 4,000ft higher than the terrain). 
The descent will be a little rough, as the flight crew will make full use 
of the speed brakes - this allows them to point the nose towards the 
ground without the aircraft speed accelerating unduly. Only when the 
aircraft has levelled out will the cabin crew begin to move around the 
cabin, checking on the passengers. They may wear portable oxygen bottles, 
in case the aircraft is still above 10,000ft due to high terrain below. 


-------------------------------------------------------------

Ditching 

The last item on the safety demonstration agenda is usually the lifejacket, 
or lifevest. Statistically, a ditching (landing on water) is most likely to 
happen on or near the airfield. Small aircraft with overwing exits (like 
the Boeing 737 and Airbus 320) do not have slides that can hold the 
occupants of the aircraft. The primary evacuation route is therefore 
onto the wing, where you should sit down in rows with your legs wrapped 
around the person in front (scissor-like). This makes you, as a group, 
more stable than if you sit individually, and you can also share body 
warmth. Larger aircraft have slides which can be used as a buoyancy 
device, so that everyone evacuates onto them and the crew will then 
detach them from the aircraft. Longhaul aircraft have slides which convert 
to rafts, with canopies to afford protection from the elements 
Don't inflate your lifejacket until you leave the aircraft, an inflated 
lifejacket may hamper your evacuation, and may get caught on debris inside 
the aircraft and deflate. Some airlines may not provide lifejackets, in 
which case, the seat cushion may be used as a flotation aid. If you end 
up in the water, try to swim to other people near you and huddle together 
to share body warmth.. Make an attempt to reach the sliderafts if you 
can - they have boarding points at each end, and lifelines along each 
side. 

-------------------------------------------------------------

In summary: 

In the event of an emergency evacuation: 
•Know where your exits are 
•Know how to operate them 
•Know how to unfasten your seat belt 
•Know how to brace properly


If there is smoke in the aircraft cabin: 
•Keep your head down 
•Use some fabric, preferably wet, over your nose and mouth 
•Keep your eyes closed 


In a decompression: 
•If you are standing, sit down and strap in 
•Grab a mask and pull it to your face 
•Stay in your seat 


In a ditching: 
•Know which are your primary evacuation routes for a ditching 
•Don't inflate your lifejacket until you leave 
•Stay together and try to remain as dry as possible 
•If you're in the water, try to swim to others and huddle together 

I hope that I haven't put you off flying. Remember, whenever you fly, 
always watch the safety demonstration and read the safety instruction card. 
It's done for your benefit and it may save your life.

About the Author - Anna Damski

I first entered the aviation industry in 1983 when I joined British 
Airways as Cabin Crew.  During my induction course, I was taught safety 
drills and procedures and basic surival principles, subjects which 
were refreshed annually thereafter.

I flew for seven years on both shorthaul and longhaul routes, on Tridents, TriStars (L10-11s) and Boeing 737s, 747s & 757s. In all that time, on all those aircraft, I never had anything even remotely approaching an emergency -- but I was always prepared, just in case!

Following the birth of my daughter, I decided to stop flying and took a job in the BA Training Centre at Heathrow, instructing Flight & Cabin Crew in safety and emergency procedures. After eight years in that position, I acknowledge that whilst I am not an expert, I feel able to impart basic advice on safety issues in flying. I left BA in early 1999 and have since been pursuing a career as an independent training consultant.

I have written this not as a definitive paper on surviving aircraft accidents, but more as a set of guidelines to raise your level of awareness when flying, in the hope that in the unlikely event you should be confronted with an emergency situation, you will know how best to act to increase your chances of surviving.
