Maintaining Autorotation Proficiency: Practice Vital To Helo Training  6
As long as there are helicopters, the necessity will remain for the pilot to be proficient in autorotations.
Thin Margins In Wintry Takeoffs  2
While anti-icing fluids negate the serious effects of wing icing, recent research has determined the fluids themselves extract a significant penalty from the wing's aerodynamic capabilities.
Brief Encounters With Volcanic Ash Can Cause Long-Lasting Damage  3
A few unsuspecting flight crews have suddenly found their transports turned into gliders by volcanic eruption materials temporarily snuffing their engines.
Improvements Underway In Volcanic Ash Detection 
Attendees at the World Meteorological Organization's Volcanic Ash Workshop in October 2015 learned of efforts to improve the forecasting of volcanic ash plumes.
Flying Tired: Recovery From Sleep Loss Is Not So Simple  11
"Fatigue-related performance problems in aviation have been consistently underestimated and underappreciated."
How Bad Is The Pilot Fatigue Problem? 
Between 2010 and 2012, more than 6,000 European pilots were asked to self-assess the level of fatigue they experienced during their flight duties. The surveys confirm that pilot fatigue is a common, dangerous and underreported phenomenon in Europe.
Sleep Loss Due To Mental And Physical Health Problems 
Lack of sleep has been linked to a cornucopia of health problems: diabetes, obesity, memory issues, delayed immune response, cancer and mental health disorders.
Cockpit Environment And Fatigue: How It Can Happen  2
Heat, glare, noise, vibrations, exceptionally dry air and confinement to a seat for hours can act synergistically to deepen the stress on a body's reserves.
Legislation Focuses On Crew Rest And Duty Rules 
The House of Representatives version of the FAA Reauthorization Act of 2018 contains a section seeking to update the fatigue rules for FAR Part 135 pilots.
T/Rs Have Direct Influence On Safety And Operating Costs 
When a thrust reverser doesn’t behave as intended, the situation instantly requires a pilot’s quick and correct reaction during a crucial phase of flight with thin safety margins.
Know Your T/Rs: General T/R Operating Guidelines 
An airplane’s thrust reverser system is designed to help the airplane decelerate after landing by diverting the direction of the engine exhaust gas stream.
High-Altitude UV Exposure: Little-Recognized Risk For Flight Crews  3
The National Council on Radiation Protection and Measurements reports that among those U.S. workers exposed to radiation while on the job, flight crews get the largest annual effective dose.
Rotary Data Tracking: Hard Lessons Learned By Doing 
I was excited when an emergency medical service (EMS) helicopter operator asked if I would help the company's safety officer get a flight data monitoring (FDM) program implemented well in advance of the April 23, 2018, deadline.
FDM Deadline Looms For EMS Helicopters
According to FAR 135.607 "Flight Data Monitoring System," as of April 23, 2018, no person may operate a helicopter in air ambulance operations unless it is equipped with an approved flight data monitoring (FDM) system capable of recording flight performance data.
Resources Required: The Need For Aviation Safety Action Programs 
Several years ago, I was asked by a helicopter EMS operator whether I would first choose to set up an aviation safety action program (ASAP) or flight data monitoring (FDM) program for an operation such as his. I have extensive hands-on experience with ASAPs and was one of the principals involved with getting the first ASAP program approved in business aviation. Now that the FAA has grown more comfortable with ASAPs outside of FAR Part 121 carriers, it is easier getting an ASAP program approved and implemented.
