Introduction THE IMPORTANCE OF APPROPRIATE,

timely, and thorough training is wellr e c o g n i z e d in aviation. Training enables personnel to develop new professional skills and accomplish necessary functions. In particular, training is critical for a professional pilot. The challenge is to determine what training is appropriate and thorough. This challenge is not static. Training requirements change, b o t h as pilots b e c o m e "smarter," and as t e c h n o l o g y changes the equipment and the environment in which the equipment is operated. The science and art of pilot training have advanced t r e m e n d o u s l y since the Wright brothers first flew in 1903. Technology now offers stateof-the-art flight simulators that accurately simulate real flight conditions. This article addresses pilot training in the context of flight operations under Federal Aviation Regulations (FAR) Part 135, Air Taxi Operators and Commercial Operators, which pertain to the majority of civil air medical operations conducted by an air operator (vendor) under contract or under an in-house FAR Part 135 certificate. FAA Requirements The FAA requires each Part 135 certificate holder to establish and maintain a pilot training program. 1 The training program and any revisions must be approved by the FAA, Noel Preston is senior associate with PRC Aviation, an aviation management consulting firm in Tucson, Ariz.

and the p r o g r a m m u s t include ground and flight training curriculums as follows: • Initial training is required for crewmembers who have not qualified and served in the same capacity on an aircraft. • Transition training is required for crewmembers who have qualified and served in the same capacity on another aircraft.

The Journal of Air Medical Transport • March 1992

• Upgrade training is required for crewmembers who have qualified and served on a particular type of aircraft, before they serve as a pilot in command on that aircraft. • D i f f e r e n c e s t r a i n i n g is required for crewmembers who have qualified and served on a particular type of aircraft, when the administrator finds differences training is necessary before a crewmember serves in 15

the same capacity on a particular variation of that aircraft. • R e c u r r e n t training is required for crewmembers so they can remain adequately trained and currently proficient for each aircraft crewmember position and type of operation in which the crewmember serves. • Emergency t r a i n i n g is required for crewmembers so they can remain adequately trained in emergency procedures. Recurrent training and emergency training are required annually. Initial,

transition, upgrade, and differences training are required only when a pilot wishes to operate a different aircraft, or to move from second-in-comm a n d (SIC) to pilot-in-command (PIC) on an aircraft for which he is already currently qualified. In FAR Part 135 the FAA does not specify the number of hours required for ground or flight training. The FAA does permit the inclusion of flight simulators in a certificate holder's training program, provided that certain requirements are met.

Training Program Alternatives Although the FAA specifies certain basic r e q u i r e m e n t s for pilot training programs, an operator may satisfy the FAA and gain approval for the operator's training program in several ways. The FAA may approve training p r o g r a m s that are a c c o m p l i s h e d entirely in-house by the operator, and approval may be obtained for training programs that utilize some degree of training resources external to the certificate holder. These external training resources may include individual flight instructors or check airmen, training provided by airframe manufacturers, or training provided by various professional training organizations. Regardless of which approach an aircraft operator chooses, it is important to recognize two points: 1. FAA approval of a training program means simply that the program satisfies the m i n i m u m training r e q u i r e m e n t s for tbat particular operation. FAA approval does not m e a n that the training provided through a particular program is the safest available, the most appropriate or thorough, or in keeping with the best industry practices. 2. Current, state-of-the-art pilot training p r o g r a m s i n c o r p o r a t e sophisticated, motion-based simulators. T h e simulators are u s e d because they can provide thorough and realistic training, while not endangering the pilot or aircraft. In this respect, flight simulators provide the capability for better and safer training. Flight Simulator Description It is h e l p f u l to u n d e r s t a n d j u s t

what a simulator is and how it works. Typically, a sophisticated simulator s y s t e m consists of the following hardware and software: • Simulator cockpit • Motion system • Visual system • Computers and related software The simulator cockpit duplicates the cockpit of the aircraft it is simulating. The controls and switches move and respond exactly as they do The Journal of Air Medical Transport ° March 1992

in the aircraft, with control forces and control travel corresponding to those of the simulated aircraft. The instruments provide indications identical to those one would see in the actual simulated conditions. In addition, the simulator duplicates significant cockpit s o u n d s that r e s u l t from pilot actions. T h e cockpit is m o u n t e d on a motion base typically consisting of hydraulically powered arms, or rams. These rams provide motion to the cockpit in up to six axes for commercial simulators. The cockpit is surrounded by a visual system that simulates visual conditions outside the simulator cockpit for the training pilots. Visual systems vary in sophistication, ranging from those that simulate only night conditions, to those that simulate dusk and night, to those that simulate day conditions. Some visual systems are further enhanced by what the industry calls "texture," a technique that adds better depth perception. In addition to simulating light conditions for a time of day, visual systems can also simulate different cloud-cover levels and visibility levels. Figure 1 contains a picture of a representative aircraft simulator. Computers and sophisticated software operate all simulator controls, instruments, switches, the motion system, and the visual system. In order to permit evaluation and qualification of flight simulators, the FAA designates simulators according to levels, with Level A the simplest and Level D the most sophisticated. 2 A sample listing of required performance standards for these different simulator levels for airplanes is shown in Table 1.

Similar wording, with reference to helicopters instead of airplanes, is found in an FAA draft advisory circular, entitled Helicopter Simulator Qualification, presently numbered 120-XX.3 FAA representatives expect this draft advisory circular to be pub-

Training Benefits The FAA states, "Simulators can

provide more in-depth training than can be accomplished in airplanes and can provide a very high transfer of learning and behavior from the simulator to the airplane. The use of simulators, in lieu of airplanes, results in safer flight training and cost reductions for the operators. "2 The Journal of Air Medical Transport • March 1992

lished for public comment sometime in 1992. Examples of the safer, more indepth training simulators can provide include the following: 1. Pilots can use simulators to learn to fly a new aircraft or to polish

skills in an aircraft in which the pilot is already experienced. This training is accomplished with no risk to personnel or property. 2. Simulated scenarios expose pilots to emergencies and malfunctions that cannot be safely demonstrated in the aircraft. For example, in a helicopter, complete loss of tailrotor drive, failure of both engines, or partial panel flight u n d e r actual instrument meteorological conditions

(IMC) would obviously pose unacceptably high levels of risk if actually attempted in-flight. 3. Crew coordination and cockpit resource m a n a g e m e n t techniques can be taught, practiced, and evaluated in both routine and emergency scenarios under all possible environmental conditions. Put in financial terms, this safer and more thorough training means significant benefits in cost avoidance.

Flight Simulator Use in Training Programs The FAA does not preclude FAR Part 135 operators from using any particular type of training. However, the training p r o g r a m m u s t be approved if it is to satisfy FAA requirements. Guidance regarding the authorization for these credits is relatively clear for airplanes. The

FAA Air Transportation Operations Inspector's Handbook lists maneuvers and procedures that must be accomplished as part of a training program and indicates which maneuvers and procedure may be accomplished in certain level flight simulators. 4 Table 2 lists a representative sampling of training requirements that may be accomplished with a flight simulator. Guidance regarding the authorization of training credits for helicopter simulators is less clear. T h e Inspector's Handbook states, 'q'he criteria for the use of helicopter flight training devices and flight simulators are currently under development. Several helicopter training devices and simulators have been individually approved using interim criteria. These devices and simulators may continue to be used in Part 135 training and checking activities in accordance with specific approvals currently in effect."4 The most recent helicopter approval, FAA exemption No. 5324, was g r a n t e d in J u n e 1991. This exemption permits accomplishment of all flight training in FlightSafety International's Sikorsky $76B simulator for an Airline T r a n s p o r t Pilot (ATP) Certificate, a corresponding type rating, Part 135 initial and recurrent training, and the Part 135 instrum e n t proficiency check. Identical approval is anticipated for FlightSafety I n t e r n a t i o n a l ' s Bell 412/212 simulator in 1992.

American Airlines Flight Academy, FlightSafety International, and SimuFlite Training International use motion-based simulators with sophisticated visual display systems to enhance or replace actual flight training in aircraft. These organizations offer comprehensive and t h o r o u g h simulatorbased professional training programs for several models of aircraft.

Other Pilot Training FSI has carried its advanced training programs beyond those aimed at a specific type of aircraft, and currently offers a g e n e r i c r e c u r r e n t training course not specific to one helicopter model. The ground school portion of this course includes a helicopter instrum e n t r e f r e s h e r course, practical cockpit management training, and an EMS pilot's review. The simulator training portion includes instrument training and a line-oriented flight training (LOFT) EMS scenario. One air medical operator who uses this program is Indianapolis Heliport Corporation (IHC). IHC operates Aerospatiale SA 365N Dauphins for a number of helicopter programs and has been sending its pilots to FSI's W e s t Palm Beach training center every six months to attend the generic recurrent training course. "We felt that it was very important for our aircraft to be outfitted for IFR and our pilots to be trained and current on a skill basis for IFR, so we started sending our pilots to FSI," says Steve Kinnaman, IHC vice president of operations. "Although we fly Dauphins and the FSI simulator is for a Sikorsky $76, we found a real positive transfer of training and skills."
