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.
Mountain Shadows: Sun Sets Early In High Terrain  7
The sky above the alpine landscape during twilight can be much brighter than the terrain below as the sun sets there early.
Videos Show Hazards Of Flying Into Degraded Illumination  5
Videos help the less-experienced pilot handle flying into degraded illumination conditions or on mountain approaches.
Pressure On Decision-Making: Clients' Wishes And Safety Can Collide 
Poor flying conditions can put clients' wishes to get there at odds with pilots' safety judgments.
Rudder Blanking Can Result In A Quick Runway Excursion  29
Many of the runways used by business aircraft lack the surface features (grooves, crowning, PFC) that lessen the effects of runway contamination.
Four Steps To Landing Safety  2
The field of safety science has developed a hierarchy of steps to reducing accidents.
When Your Only Engine Fails  40
Pilots of single-engine aircraft have long debated the “best” options for reacting to an engine failure after takeoff.
When In-Aircraft Training Kills  2
On June 24, 2006, a private pilot was receiving flight instruction in a Pilatus PC-12/47 at Big Timber, Montana's uncontrolled airport. Conditions for the departure from Runway 6 included winds at 17 kt. gusting to 23 kt. Witnesses said that the pilot had transmitted on CTAF with the intention of practicing a loss of engine power after takeoff, and turning 180 deg. to return to the airport. He and his instructor never made it back.
Single-Pilot CRM  3
How to master automation, communications, navigation, systems and the rest when you are a crew of one.
Managing Checklist Interruptions 
Many of the checklists designed for business aircraft are lengthy, especially when addressing critical phases of flight, and they can increase a pilot's workload, thereby detracting from the primary task of managing the aircraft's trajectory. The challenge becomes compounded whenever the list is temporarily halted for whatever reason.
