F-15 to F-35 Engines

  For this weeks blog post I did not have to look anywhere but instead listen.   What I mean by that is the F-15 and F-35’s taking off outside my house is what gave me inspiration to write about what I know and love, jet engines.   The F-15 carries around 2 F100-220/229 and has been doing so since the 1970’s and it is my job to tear down, inspect, rebuild, and test these engines making sure they can stay in a Jet as long as possible.   Pratt and Whitney also had this in mind as they constantly update and revise certain things inside the engine whether it’s a Turbine, Stator, or even an engine computer, they are constantly learning and tweaking the engine to make it more efficient and stronger.   They also used this motor to help develop other motors, to include the F-135 engine.               With the new F-135 engine, producing double the thrust of a 229 (roughly 43,000 lbf) it also derived in a way from a 229.   As Airforce technology explains “Components from F119 and F100-229 e

The Development of Crew Resource Management

For my blog I am going to talk about the introduction of Crew Resource Management (CRM) and what led to its development.   First, it must be noted that CRM did not emerge from a singular accident but was influenced by a series of accidents and incidents.   CRM was created in response to the realization that many aviation accidents were either caused or exacerbated by the human factor of communication.   During these critical times when an emergency happened there was a lack of communication between the pilots and flight engineers, poor decision making, and ultimately led to an inefficient team and flight deck.             As mentioned, multiple accidents led to the development of CRM but one notable one was the Tenerife Airport Disaster in 1977.   This disaster was caused by two Boeing 747 colliding on the runway and killing more than 580 people.   The weather this day was foggy and air traffic was very busy and all communications were through just the pilot.   The miscommunication b
