Multimedia essay by: David Johanson Vasquez © All Rights
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.

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.) It’s the R22’s light weight, which in my opinion, gives you the most thrill for getting from point A to point B.
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.
Ξ 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 noise caused 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 companies, 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 craft and the summer afternoon, which was used to shoot these aerials, had strong turbulence, so some scenes will have some 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 Θ Boeing 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 serious threat to both flight and ground crews.
Outcomes From Infrequent 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 struck the 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 a photo of the accident scene from the Spokane, Spokesman Review – May 7, 1985 edition. The story has comments from a Federal Aviation Administration (FAA ) official coordinating the accident’s investigation. Ironically at 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 was of the loss of 17 Marines in a large 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 sheriff’s department to State his own flight service business. Over time, parts needed to be replaced with upgrades and he was sold a defective fuel-line, which was installed and 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 (emergency helicopter procedure, which shifts rotor blade’s pitch to use stored kinetic energy for making 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 airframe mechanic and or a power plant mechanic 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.
Both videos demonstrate the essential level of professionalism required for helicopter operations during a high volume of jet and helicopters landings and takeoffs at Boeing Field.
