Helicopter crashes can happen on any kind of flight, including short corporate helicopter jumps from city to city. “Let’s say you are flying from Toronto to Ottawa, Canada,” said David Arama, director of the WSC Survival School in Cloyne, Ontario, and author of the new survival book, ‘How To Start a Fire With Water’. “This is an hour-long flight path that passes over Algonquin Provincial Park: If your helicopter goes down there, you need to be prepared to survive in a wilderness situation!”
Similar risks exist for American pilots flying across natural preserves and forested mountains; even in the heavily urbanized Eastern Seaboard. Add the post-crash challenges of unexpectedly landing on water – risks that exist even for helicopters hopping across New York City – and planning to survive after a crash should be a priority for all helicopter pilots.
Unfortunately, “90 percent of helicopter pilots do not take survival preparations seriously,” said Arama. “They often fly with inadequate safety training and equipment; lacking anything beyond a car-quality first aid kit, and not knowing if their aircraft’s Emergency Locator Transmitter (ELT) is functioning properly. Should a crash occur, these pilots are utterly unprepared to survive until help arrives -- especially if they land in an hard-to-access area in bad weather where assistance can take days to get through.”

Have you ever accidentally done a loop in a helicopter on a moonless night at 1,000 feet on downwind leg to an airport because the pilot flying lost spatial orientation? I have. The sudden and abrupt transition from controlled flight to uncontrolled flight, when the pilot “lost it,” then fighting for control, took me as much by surprise as it did the poor pilot.
He was an airline transport pilot with more than 5,000 hours in the aircraft. He wasn’t new to instrument flying, having logged hundreds of hours of actual instrument time using NVGs in a Blackhawk working for the Drug Enforcement Administration in Colombia.
Luckily, this “flight” took place in a $14 million, Level D, full-motion Bell 412 flight simulator in Dubai that I was operating as a flight simulator instructor, flight examiner, and CRM assessor for Abu Dhabi Aviation. To test my pilot’s hand-flying skills, I had given him an autopilot failure on downwind, which caused him to have to fly the machine into dark nothingness.
Because I have seen several experienced pilots “lose it” in the sim, it’s caused me to come to the realization of how important it is to have a plan of action before one does go into inadvertent instrument meteorological conditions (IIMC). This brings me to the topic of line-oriented flight training, or LOFT.

The field of aviation training devices and simulators is an ever evolving and interesting area. As expenses increase in so many sectors of the rotorcraft industry, devices (which don’t move) and simulators (capable of motion) help contain training and certification costs. [NOTE: In this article, the terms “sim” and “simulation” are used at times to collectively refer to both types of trainers.] Sims can create flight scenarios that are too dangerous to duplicate in actual aircraft, and make practicing other procedures safer. For example, more fatal training accidents occur practicing autorotations than any other skill. Simulation for such scenarios can save lives.
Basic aviation training devices (BATDs) and advanced aviation training devices (AATDs) are now so affordable that primary flight schools have embraced using them to teach instruments, navigation, systems, and emergency procedures. Until the introduction and acceptance of these devices, these schools simply could not afford to acquire high-end flight training devices or full flight simulators.
Simulation is governed by two FAA groupings: those that fall under the authority of AFS-205 National Simulator Program, and those that are governed by AFS-810 General Aviation and Commercial Division.

Ever wonder how many times you signed your name and A&P number after the word “airworthy.” For me, it’s in the thousands. So, how does a mechanic define it?
For some, the definition is rigid: the aircraft must be in like-new condition with a pristine record trail. For others, it’s a gray area of personal decision, defined by an aircraft’s use, age, and regulatory compliance.
Regardless of interpretation, the airworthy condition of an aircraft is the core function of a mechanic. Yet, an official FAA definition of this fundamental word is lacking within our maintenance regulations and guidance material. Let’s try to find one.
The Basics
Numerous articles, papers, and FAA documents offer various descriptions of airworthy. The common accepted version today requires an aircraft to conform to its type design and to be in a condition for safe operation.
Looking to the Federal Aviation Regulations (FARs), essential terms and their definitions are usually given at the beginning of a chapter, part, or section, along with an applicability clause. FAR Part 1, Definitions and Abbreviations, applies to “Subchapters A through K of this chapter,” so it seems it would be a logical place to find a definition for airworthy, since our Part 43 falls under Subchapter C.
Unfortunately, the definition is not listed in FAR Part 1, or Part 43, or Part 65 for that matter. Given its significance, you would think airworthy, or airworthiness, would have its own part in the FARs.

A 15 September 2016 article in The New York Times titled “‘Miracle on the Hudson’ Safety Advice Not Carried Out,” had these sobering words:
In the seven years since an airline pilot saved 155 lives by ditching his crippled airliner in the Hudson River, there's been enough time to write a book and make a movie, but apparently not enough to carry out most of the safety recommendations stemming from the accident. Of the 35 recommendations made by the National Transportation Safety Board in response to the incident involving US Airways Flight 1549, only six have been heeded.”
The airline pilot referred to is, of course, Captain Chesley “Sully” Sullenberger, who recently sounded a similar refrain on his Facebook page:
“I’m very disappointed so many of the important safety recommendations made by the National Transportation Safety Board after Flight 1549 have not yet been mandated by the FAA. Unless the FAA mandates safety improvements, airlines historically will not adopt them. We owe it to everyone who flies to act on what is learned from accidents, often at great cost in lives lost, instead of just filing it away to gather dust while we await the next accident.”

Trouble with autos. Seriously?
When I flew for the Royal Oman Police, the British, Scottish, and Australian pilots I had the pleasure to fly with had a lovely saying. Whenever they wanted to convey an idea, but wanted you to know that you may already know it, they would preface their statement by saying, “Now, I don’t want to teach Granny to suck eggs but….”
Similarly, I certainly don’t want to tell you something you may already know, but to my great amazement it seems there is ‘some problem’ with how pilots execute autorotations, which to me is an easy but fundamental maneuver. So, at the risk of “teaching Granny to suck eggs,” please indulge me while I offer my 2 cents’ worth on the subject that has served me well over the years. At the same time, I apologize if you already practice autorotations in the way I will describe.

Prior to the flight portion of an FAA exam, the applicant will be tested on their knowledge and ability to conduct a preflight on the aircraft being tested. It is imperative that a pilot understand the systems of the aircraft they plan to operate. The ability to determine airworthiness can only be accomplished when the pilot has adequate knowledge of their aircraft and knows what to look for (normal vs. abnormal) during the preflight process.
A few weeks ago, I was picking up an aircraft that had just completed a heavy maintenance inspection. Many of the aircraft’s flight components had been removed, overhauled, and reinstalled. Before I conduct an operational check flight (OCF), I like to establish a personal relationship with the maintenance staff working on the aircraft. Having conducted many post-maintenance OCFs, I’ve grown accustomed to the nuances of maintenance technicians and appreciate that each maintenance facility’s processes and procedures may differ. In the case of the aircraft in question, I did not know all of the mechanics. The main gearbox and rotorhead was completed by a mechanic new to the facility. Since this situation occurs often within our industry, it gave me no great concern; I had faith and trust in the quality assurance process of the system.

In a bid to improve operational safety, helicopter air ambulance (HAA) operators Air Evac Lifeteam and Air Methods are incorporating two-axis autopilots into their light single-turbine helicopters. Air Evac Lifeteam is updating the Bell 206 Long Rangers and Bell 407 helicopters in their 150-plus helicopter fleet with Genesys Aerosystem (formerly Cobham) HeliSAS Autopilot and Stability Augmentation System (and Garmin 500H glass cockpits) by the end of 2017. Air Methods is focussing on including autopilots whenever it purchases new helicopters for its 400-plus fleet, including the 200 Bell 407GXPs it is purchasing between now and 2024. The Bell 407GXP comes with a Garmin G1000H glass panel avionics system integrated to a Bell-designed autopilot system for a cutting-edge combination that can also be retrofitted into the Bell 407GX.

I’d been awake for 17 hours when the phone rang at 12:45 a.m. The communications specialist said, “There’s a scene call on Palomar Mountain. Will you be able to take the flight?”
“Well, I’ve only had one shot of Tequila, but let me check the weather and I’ll get right back to you.”
Sound implausible? The shocking truth is that it’s not—not when you consider a study published in the British Journal of Occupational and Environmental Medicine, where researchers in Australia and New Zealand determined that from 16 percent up to 60 percent of road accidents involve sleep deprivation. This reflects some of the same hazardous effects as being drunk. Although I had never actually had a drink that night, my cognitive thinking, my body, and reflexes were as adversely affected as if I had.

Imagine a future where helmet-mounted night vision goggles (NVGs) are replaced by light-enhancing contact lenses. While this might seem like some high-tech invention in the latest Mission Impossible movie, the idea itself isn’t fiction. Rather, researchers at the University of Michigan have developed a super-thin, graphene-based light detector that can see light wavelengths invisible to the human eye. This includes the thermal energy detected by NVGs that is amplified and rendered into human-viewable black and green/black and white images.
