& Treats<br />

The [F]light Side<br />

Every industry has a work jargon that may seem confusing to outsiders. This includes the airline<br />

industry to which pilots, stewards and aeroplane engineers have a set of slang terms they use either<br />

while flying or on land. Here are three terms that you will know, should you come across them the<br />

next time you fly!<br />

Call signs<br />

In aviation, call signs are essentially nicknames assigned<br />

as unique identifiers to an aircraft. Call signs can also<br />

be assigned to identify pilots or during the transportation<br />

of heads of state or government officials. For example,<br />

the call sign for the country's national carrier, Malaysia<br />

Airlines, is MALAYSIAN while AirAsia is known as the<br />

RED CAP. Meanwhile, the US President's aircraft is<br />

known as the AIR FORCE ONE.<br />

Blue Juice<br />

The lavatory water is blue. So, when we you overhear<br />

a steward saying something along the lines of, "The<br />

lav is out of blue juice," perhaps you might want to<br />

hold it in for a while. How did this all come about?<br />

Through the mid-1980s, aeroplane toilets used Anotec,<br />

the blue deodorising liquid you see in the bottom of<br />

toilet bowls, to push waste from the bowl into onboard<br />

storage tanks. Electric pumps actively drive this<br />

process, circulating fresh fluid through with every flush.<br />

Mayday<br />

Mayday! Mayday! Mayday! The international radio<br />

distress call, is always given three times in a row to<br />

prevent it being mistaken for any similar-sounding<br />

phrases. The word is an anglicisation of the French<br />

m’aidez or m’aider, meaning 'help me'. In 1923, London's<br />

Croydon Airport senior radio officer, Frederick Stanley<br />

Mockford chose the word to indicate distress and it<br />

was agreed upon that it would be easily understood<br />

by all pilots and ground staff in an emergency.<br />
