Have you ever traveled by helicopter and encountered a full-throttle-ride at a tree top level? Part 2 of my Helicopter video series is now online for you to experience. There are valuable safety tips, aerial photo techniques, employment requirements for helicopter mechanics as well as the ultimate joyriding aerial views of Boeing Field and Seattle!
Collaboration and Clear Communication
Clear communication and teamwork between helicopter pilots and flight mechanics is essential for aviation safety. Professional collaboration and working experience is also required between a pilot and photographer for ensuring successful photographic results. On the day of this aerial photo shoot the helicopter we were using had some technical issues, which needed repairs before continuing the project for the Port of Seattle. With solid communication between pilot and ground crews established, the repairs were completed as the fast and furious activity of aircraft went on all around us.
A February 2007 Rotor & Wing Magazine article by Tim McAdams, used two tragic crash events involving helicopter aerial photography to illustrate potential hazards encountered from the helicopter’s rear rotor. In the article it reported, “the NTSB determined the probable cause as the pilot-in-command’s improper in-flight decision to maneuver at a low airspeed with a left quartering tailwind, which resulted in a loss of tail-rotor effectiveness.” The investigation of these and similar crashes helped to create the FAA Advisory Circular AC90-9, that warns pilots of conditions which can cause loss of flight stability due to stress on rear rotors.
Under no circumstances should anyone including ground crews be near the helicopter’s rear rotor while the engine is on. The video shows why helicopter rotor blades are painted with bright patterns to warn of their potential danger.
Fast and Furious
Helicopter operations are virtually never boring and are the centers of major activity. See how the latest video in the series explores Seattle’s dynamic landscape, Boeing Field operations and helicopter safety.

The Robinson R22 helicopter is often described as a sports car version of helicopters — ultra light in weight, it takes off quickly and is so responsive it will literally make your head spin. Weighing in at only 1200 pounds fully fueled, it often feels like you’re wearing the helicopter like a “jet-pack” rather than riding in it. As a thrilling life experience, helicopter flights are at the top of the list, however, it requires the highest level of professionalism to safely fly and be involved with helicopter operations.
The Initial Reason for the Project As a multimedia specialist who produces stories supported by photography and video content, I’ve used a variety of helicopters for an image capture platform. Everything from the compact, high – performance Huey 500D up to the large tandem rotor Kawasaki KV 107 (a licensed version of the Boeing Vertol BV107 “Chinook” helicopter.)
The Robinson R22 Beta II Helicopter was arranged for me to use ◊as part of a six-month photography contract with the Port of Seattle.In between locations photographed for the Port, I shot video content for multimedia educational applications.

Advantages & Challenges For Image Capture From Helicopters
The advantages of using a helicopter over an urban setting are many, including: multiple low angle views, which are unavailable when using fixed winged aircraft, hovering over specific areas, an efficiency in reaching desired altitudes for a variety of perspective views.
◊Aerial photography and especially video are challenging to produce in a helicopter compared with using fixed winged aircraft. ↑ Two major issues, which can hamper imaging are: vibrations and noisecaused from the engine next to the cab and rotor vibrations caused from elastic torsion deformations while flying. Aerospace companies such as Boeing and big budget feature film projects will occasionally use high-end aerial photography, which have specialized cameras mounted into their aircraft. This specialization can reduce some aerial photography vibration issues associated with hand held cameras, but it requires a large budget to justify the expense. The R22 helicopter is a very light aircraft, the summer afternoon, which was used to shoot these aerials, had strong turbulence, so some scenes will have unavoidable vibration and noise in them.
This is the first of two videos, which features aerial views of Seattle provided by Helicopters Northwest out of ΘBoeing Field. The second video, soon to be posted, shows the return for refueling and includes initial mechanical issues getting the helicopter back in the air. In regards to refueling, it’s critical a helicopter has been properly grounded before operations begin. ↑ Helicopter rotor blades are capable of generating large amounts of static electricity — especially in dry, dusty environments, which can pose a serous threat to both flight and ground crews.
The Outcome From Rare Helicopter Accidents Are Usually Tragic… But There Are Exceptions
One of my first jobs after graduating from college was with KREM-TV (King Broadcasting) in Spokane. A few years after I moved on from working with the station a tragic accident occurred with its news helicopter. The helicopter had just picked up Gary Brown —an outstanding KREM videographer (who I remembered as always being upbeat, positive and friendly) — when its rotor blades suddenly struck guy wires supporting the station’s transmitter tower. Both the photographer and pilot were killed instantly.
I’ve included a link below, which has an article with an accident scene photo from the Spokane, Spokesman Review in a Tuesday, May 7, 1985 addition. The story has comments from a Federal Aviation Administration (FAA) official coordinating the accident’s investigation. Ironically on the same page is a syndicated, New York Times story of a larger helicopter accident, which occurred on the following day of May 6. That tragedy involved the loss of 17 Marines in a massive Sikorsky, CH-53 Sea Stallion off the southwestern coast of Japan. A joint operations helicopter reported witnessing the CH-53 suddenly lost power and dropped 500 feet into the sea.
About ten years ago a friend of mine survived a helicopter crash, with only a few scratches. He had bought a used helicopter from a sheriffs department to start his own flight service business. Over time, parts needed to be replaced with upgrades and he was sold a defective fuel-line, which failed while in flight. He was approximately 100 feet in the air with two clients when the helicopter’s engine shuttered to a stop. Fortunately he got his helicopter into ↑ auto rotation ( helicopter emergency procedure, which shifts rotor blade’s pitch to use stored kinetic energy to make a “soft landing”) and as they began descending, the helicopter’s skid caught the center of a tree and its branches helped them slow the descent even more.
Education and Training Is the Key to Helicopter Safety
Overall, if you consider how many hours and flights in a day helicopters perform flawlessly — they are safe and reliable. What these specialized aircraft can achieve in vertical maneuverability and performance is nothing short of marvelous and amazing. ↑ To ensure engines and structural frames are safely maintained the FAA certifies aviation mechanics using two certifications. Helicopter mechanics are required to have: an air frame mechanic and or a powerplant mechanics certification. Most employers prefer their mechanics having both certifications, which requires 1,900 hours of coursework in order to pass oral and written exams that prove their skills.
Each video in this multimedia essay demonstrates the essential level of professionalism required for aviation operations during a high volume of jet and helicopters landings and takeoffs at Boeing Field.
Now, just sit back and take in the sights! ~
