HOW TO SURIVE A PLANE CRASH

Passengers on a Japan Airlines flight today were moments away from death, but this is what they did correctly to stay alive! Your cabin crew need you to:
1. Remain Calm
2. Follow all their every instructions
3. Not stand up and start opening bins and taking bags
4. Help at the bottom of the slide those passengers coming behind you
5. Not stop and take photos next to the burning airplane. It could explode at any moment
6. Run to far distance and continue following the instructions of safety personal The passengers of Japan Airlines flight JL516 are all alive because they acted as if all the lives on the plane were more important than their belongings, and they followed the commands of their crew. Both the crew and the passengers did a fantastic job surviving this plane crash.

To stay safe please follow the instructions of the cabin crew 🙏💙….

The difference between de-icing and anti-icing

Pilots are required to ensure that the wings and all control surfaces are clear of any form of frozen contamination.

Even small amounts of ice on the wing can significantly reduce its lift capability as well as the stalling angle of attack.

De-icing fluid is used when the aircraft is contaminated with snow or ice which needs to be removed, but no further freezing precipitation is expected before departure.

This can be accompanied by spraying heated fluid onto the aircraft to remove the contamination.

If protection from further frozen contamination buildup is required, such as when it's snowing, we then spray a second fluid over the clean wing, which adheres to the wing and prevents the buildup for a period of time.

This time of protection is called the 'holdover time'

Pilots calculate the holdover time for the fluid used by using tables and entering the fluid type, concentration, type of precipitation and temperature.

As a general rule, the higher the number of the fluid used, the longer the holdover time.

Eg Type 2 fluid offers a shorter holdover time than Type 4.

The fluids can also be diluted to offer varying levels of protection. Eg 75/25 This means that the mixture being used consists of 75% de-icing fluid and 25% water.

The longest holdover time is achieved by using 100% fluid but this can be less environmentally friendly and very expensive.

So if we can achieve the desired holdover time with a lower dilution, we can enhance the efficiency of the operation.
