9 New Security Measures For Flights and How They Will Affect You

A lot has happened in the last few days to change the way that we all will be travelling in the future. There will be new security measures for flights based on these recent incidents.

Firstly, I am sure you all have heard or read about the 23-year old Nigerian man, Umar Farouk Abdulmutallab, who allegedly attempted to blow up a plane he was on as it neared Detroit Metropolitan Airport on Christmas Day. He had a peroxide-based bomb attached to his body, and when he detonated it, the bomb, thank God, sparked a fire instead of an explosion.

The Nigerian man had told fellow passengers that he felt sick, and pulled a blanket up around his body and neck, and proceeded to ignite the bomb that was stored in his underwear. Pops were heard and smoke was seen. Quick action by the flight crew and passengers subdued Abdulmutallab. All ended up safe at the end of this flight with the exception of Abdulmutallab, who is reported to have suffered third-degree burns.

Then, two days later a man from Florida, 67-year old Thomas Ouellette, reportedly brought a pyrotechnic device onto his flight that landed in NYC’s LaGuardia Airport last Sunday night.

The question is: How will these new security measures for flights affect the rest of us when we travel?

According to a report on CNN today, U.S. Travel and Security Authorities, international airlines and airports, and aviation organizations have all moved quickly to implement a range of new security measures for flights that will impact travellers’ normal routines.

At present, only flights to the U.S. are affected. Passengers can expect to see extra security “at international airports such as increased gate screening including pat-downs and bag searches. During flight, passengers will be asked to follow flight crew instructions, such as stowing personal items, turning off electronic equipment and remaining seated during certain portions of the flight”, stated The Transportation Security Administration.

New security measures for flights include the following for the last hour of flight over U.S. Territory:

  • Passengers will not be allowed to leave their seats for the bathroom
  • No access to luggage, especially in the overhead area
  • Not able to keep blankets or pillows on your lap
  • Bans on using laptops and MP3 players
  • Restriction for the use of cabin phones

Additional New security measures for flights include the following:

  • Arrive at the airport at least three hours before your flight
  • Be prepared for longer wait times to clear security
  • Be prepared for pat-downs from security and individual airline security personnel
  • Be prepared for additional inspection of carry-on baggage and personal items before boarding your flight

The Detroit incident has shown a hole in airport security measures. Could the next step possibly be a ban on all hand luggage, including handbags and purses?

As of today this is what some airlines are telling their passengers about the new security measures for flights:

British Airways is advising all passengers travelling to the States to minimize hand luggage to only one piece. Holiday presents that are wrapped will be opened and inspected.

Cathay Pacific is advising their passengers to expect pat-downs from security and inspection of carry-on baggage and personal items before boarding the plane. Also, the use of cabin phones will be restricted at all times during the flight.

American Airlines advises all passengers to arrive at the airport at least three hours before the flight to allow for added security checks.

Our take on the new security measures for flights? We would rather be safe than sorry…..if it takes extra time to be cleared through Security – so what? If it turns out that you have an extra hour to wait for your flight, get something to eat (it might be better than the food on the plane anyway), make those last good-bye phone calls, start reading your book, take time to talk to your travel partner, go to the bathroom an extra time for good measure.

To sum it up: Arrive early, have your paperwork including passport ready, a tight grip on your patience, be cooperative…..and remember, smile, smile, smile.

Wind Anemometers – How to Measure Wind Speed Accurately

For a science that is constantly in the lives of everyday folk, wind speed measurement certainly manages to keep out of the public eye. The measuring of wind speed happens to be an important part of a number of everyday technologies. Of course there is meteorology, the measuring of weather phenomena, that wholly depends on the gauging of wind speed; but a surprising number of other everyday specialties depend on wind speed measurements too, chief among them being aviation and marine and navigation, stability management in skyscrapers, environmental sciences and disaster management. Wind measurement is done with a device known as a wind anemometer; though it might be argued that that is a redundancy since anemometer comes from the Greek Anemos = wind.

Any device that measures wind speed is bound to sense the pressure of it too. For this reason, many anemometer designs are successful when used as pressure meters too in addition. A version of anemometer is known to have existed since around 1450. The modern wind anemometer though, has been around for more than a century and a half now; the first successful design was one that used a structure with four arms fanned out, each one with a cup attached that caught the wind and spun the structure. The inventor, Dr. John Robinson, held the impression when he made his invention that any cup anemometer would share the characteristic that it would spin at a third of the speed of the wind blowing past it, no matter what size it was built to be. Researchers took his word at its face for quite a while before it was discovered that the size of design used always affected the results. Researchers who had used the inventor’s figures for their calculations for years had to start over from scratch.

Cup anemometers, these simple devices, are remarkably accurate machines today nevertheless; the best examples can approach a 99% accuracy level, and still be no more expensive than about $1000. But the cup anemometer is still a mechanical technology that is prone to maintenance lubrication issues, friction, mechanical damage and ice formation. There are competing technologies that attempt to eliminate the problems seen in the mechanical design. One of the most popular wind anemometer technologies in use today is the ultrasonic kind. The principle of the ultrasonic design is this: the speed of sound depends on the speed and the direction of the air that it passes through. A headwind slows sound down, and a tail wind speeds it up. An ultrasonic wind anemometer fires high-frequency sound pulses back and forth between two receivers. If the pulse takes more time travelling in one direction than the other, that is a sign that the slower trip had a headwind working against it. The time differential helps calculate the wind speed. You’ll find these in use on tall buildings, on weather buoys and at weather stations.

Another wind anemometer design that is particularly ingenious is the constant-temperature anemometer. A thin wire held between two electrodes is heated up electrically to hold a constant temperature. A sensor measures the amount of current needed to hold the temperature at ambient temperature levels. Any loss of temperature that is faster than would be explained by the ambient temperature levels would have to come from wind speed. This is a particularly accurate method of measurement of wind turbulence. However, like the laser measurement method below, this can be a quite inexpensive device to buy and maintain.

Ultrasonic and constant temperature anemometers may be accurate enough for most purposes; but laser Doppler anemometers offer extremely tight accuracy. A laser anemometer uses two laser beams; one that travels through a sealed and clean pathway, and one that travels through exposed air. The beam that travels through the exposed air encounters dust particles that are borne along at the speed of the wind at the point. The laser bounces off those dust particles, and measures by Doppler shift the speed at which the particle has been traveling. The Doppler shift is compared to what is measured for the beam traveling through the sealed tube and a relative measurement is made.

It would appear from these descriptions that anemometers always need to be large and permanent installations; as it happens though, small and inexpensive handheld versions with digital displays exist for use by field researchers and trainer pilots. The most striking feature of these is the way they recognizably use nothing other than the same mechanics and structures of the professional devices, only miniaturized for handheld use.

Travel Trailer Covers – Buying the Right One

With all of the excitement of purchasing a new camper, the thought of protecting it when not in use may be overlooked. Since your camper may be such a large investment, you should do everything you can protect it. Travel trailer covers are probably the least expensive way to protect you camper. From the damaging UV rays from the sun, dirt and dust, heavy rain fall and freezing winter weather (for some of us), having your camper covered with a quality RV cover is one way you can ensure your camper is protected and extended its life.

When you’re shopping for RV trailer covers, it is important to know the right size to buy to make sure you have a good fit. Just because your owner’s manual says that it is a 29 foot camper doesn’t mean that it actually is! You will want to measure the camper for yourself. When you go to measure your camper you are going to measure from end to end. Start at the furthest point of the camper at the rear of your camper. Be sure to include the ladder, bumper or spare tire. Measure to the front of the camper but do not include the propane tanks or hitching. If you have a roof air, be sure to add an addition one foot to the final measurement. Now that you have your measurements, you are ready to start your search for travel trailer covers.

One important feature to consider is your climate. If you climate is damp, it is especially important to consider travel trailer covers that “breath”. Tyvek Travel Trailer Covers are made with Polypropylene sides to ensure maximum breathability and it virtually eliminates mold and mildew. Its two layer Tyvek top panel resists water and allows trapped moisture to evaporate from within. UV protection is also very important in all climates.

Other features to consider are the travel trailer covers straps and buckle attachments to prevent billowing on windy days, reinforced corners to resist tears and heavy duty zipper “doors” for easy access to your travel trailer while it is covered. Many brands of travel trailer covers are being designed with many zippers to allow access to your camper no matter where the entrance door is located.

Since travel trailer covers will be exposed to the elements, they will weaken over time. You will want to find a cover that has a good warranty. These covers are going to protect your investment so you will want to make sure that it is of good quality and will last for many seasons. It is important to know how long the warranty is and what the warranty covers.

When you have decided on the brand and type of travel trailer covers that you are going to purchase, you will have to choose the cover size. If you are sure that you have measured correctly, now you will need to locate the size that is closest to your measurement. RV covers are made to fit a size range like 24’1″ to 26″. Find the range that is closest to you measurement. It is better for it to be a little bigger than it is for it to be a little too small. If it is too small, you will have to stretch the material to fit with can cause unnecessary strain to the cover. Besides, most of the better made travel trailer covers allow you to tighten up the corners and edges to make for a better fit.

You have made a wise choice in considering protecting your camper with a cover. Whether you are storing your camper indoors or outdoors, travel trailer covers will keep you camper cleaner and in better condition which will extend the life of your camper as well as keeping the resale value higher if you should choose to sell or trade in your travel trailer.
