Don't Buy An Aviation Headset Until You Have Read This Article Entirely  by Roger Brown

If you have been a pilot for any length of time - flying with or without an aviation headset - you may have already lost some of your hearing. You can't reverse the damage that has already occurred, so you need to take action now to protect what you have left.

Pilots experience damaging noise for long periods of time - that is unavoidable. The sound in the flight environment is intense.

First, there are 3 aspects of sound that define cockpit noise:

1. Frequency (Hz - Hertz)
2. Intensity (dB - decibels) 
3. Duration of the sound

This is how some typical environments rate in sound intensity…

• Jet cabin - 60-88 dB 
• Small single engine airplane - 70-90 dB 
• Single engine helicopter - 80-102 dB  
• Average office - 40-60 dB 
• Major city street - 80-100 dB
• Chain saw/lawn mower - 100-110 dB 
• Rock concert - 115-120 dB  

Here are the sound limits before hearing damage occurs...

• Ear discomfort - 120 dB 
• Ear pain - 130 dB
• Eardrum rupture - 140 dB
• Temporary hearing impairment - 2-3 hours of noise greater than 90 dB
• Permanent hearing impairment - 8 or more hours/day to sound greater than 90 dB for 2 or more years.

The worst thing is the way loud noises affect your flying…

• Distraction and fatigue
• Hard to make out what others are saying and difficult to understand them - in other words, you have to shout to be heard  
• Decrease in personal performance by decreasing concentration

Here's what you can do about it...
….Use hearing protection - here are your options…

1. Earplugs - wax-impregnated polyurethane are the best and block out the most noise 
2. Aviation Headset - the cheapest ones just physically block the sound out 
3. ANR Aviation Headset - these headsets block out the sound physically with the added dimension of matching cockpit noise with mirror-image sound that cancels out the noise  
4. Combine earplugs with headsets - this is an extreme step, really only for super-loud environments over 115 dB

Conclusion:
You can't regain your hearing.
The moral to this story is to get aggressive with hearing protection while flying. You spend upwards of $500 for flight in many aircraft, so what is the point of skimping on a headset?
Check out your headset options today. Try several types and makes to see which works best for you. Aviation headsets are like clothes or shoes - what fits one person doesn't necessarily work for another.

Types of Aviation Careers: Options for You to Consider   by Brendon Taylor

The aviation academies and pilot training institutes train the aspiring trainee pilots to fly aircrafts skillfully and confidently. The professional pilot training courses utilize latest study materials and advanced technologies to train the students. The pilot training academies are located near the flight centers. Flight simulation is an important part of the pilot training courses. The centers are mainly located near the airports. The aviation academies often assist the trainees to find reasonably priced accommodation near the flight training centers. Both day time and night time usage of simulators are possible at the simulator centers.

Certified, highly approved, technically advanced simulators are used at the flight training centers. At the simulator centers the B 737 and A 320 type simulators are available which are well equipped with the advanced technologies and gadgets. The flight simulators at the centers use advanced technologies like satellite imagery based visual system, electric motion technology etc. Prior to the training at the flight simulator centers the pilots undergo the virtual training sessions. Virtual training uses touch panel device where candidates can view and operate aircraft control panels, displays, instruments and indicators and experience real time interaction with aircraft devices.

Flight simulation is an important aspect of pilot training courses. Flight simulators at the centers utilize various types of gadgets, devices, controls, displays, software, complex models and aerodynamic concepts. Flight simulators artificially recreate aircraft environment and aircraft operational conditions. Flight simulators at the training centers make the trainee pilots learn the technicalities of flying an aircraft. Technical concepts of an aircrafts flight; the response generated by aircrafts to their gadgets, controls, instruments etc; the effect of external factors like thunderstorms, air density, cloud, rain, hail and other weather conditions on aircrafts etc are some of the important lessons learned by the help of flight simulators.

Various advantages of pilot training courses:

• Experienced and highly qualified trainers and flight instructors train the aspirants. The classrooms are well maintained and technologically well equipped, with computers, gadgets and e-learning facilities. The pilot flight training courses make the candidates aptly qualified to fly technologically advanced airplanes successfully. The pilot training courses include lessons on flight concepts, aircraft systems and performance, flight controls and displays, instruments, basic navigation, radio navigation, engines technicalities, meteorology etc. 

• During the accelerated pilot flight training courses, training is given for both single engine and multi engines airplanes. Training related to aircraft instrument operation is also provided to the candidates. Technically advanced, well maintained and well equipped aircrafts are used during accelerated pilot flight training. The aircrafts are safe and well equipped with facilities like advanced weather radar, GPS system, multiple displays etc. 

• Ground training involves training on RTR (Radio Telephony-Restricted), meteorology, air regulation concepts, air navigation, technical operations etc. Students sit for exams at various approved centers to qualify and obtain their valid licenses. Cockpit training includes training on documentation, aircraft loading, government rules, carrier responsibilities, emergency situation handling etc.

 

Call of Duty

Call of Duty is a first-person shooter video game developed by Infinity Ward and published by Activision in 2003. The game simulates the infantry and combined arms warfare of World War II. As a first-person shooter, Call of Duty places the player in control of an infantry soldier who makes use of various authentic World War II firearms in combat. Each mission features a series of objectives which are marked on the heads-up display's compass; the player must complete all objectives to advance to the next mission. The player can save and load at any time, rather than the checkpoint system utilized in later Call of Duty games.

The game is made up of three campaigns, which the player controls three soldiers of three different nations: Private Joe Martin of the United States, Sergeant Jack Evans of the United Kingdom, and Corporal Alexei Ivanovich Voronin of the USSR.
