00 Introduction To Helicopter Simulation
About:Welcome, fellow simmers, to the ultimate yet basic guide to becoming a virtual helicopter pilot! I'm Feenx, your friendly neighborhood gamer, and flight sim enjoyer. I'm also a dude that operates these egg-beaters with some real-world experience under my belt. I'm here to spread some knowledge and help you soar through the virtual skies like a pro.
Whether you're a total newbie or a seasoned virtual pilot looking to level up your skills, this guide has got you covered. We'll kick things off by mastering the fundamentals of helicopters, from the mind-bending physics of flight to deciphering those funky flight instruments. We'll even delve into the mysterious world of preflights (cue dramatic music).
But hey, it's not all about theory here. We'll also get hands-on with practical skills like takeoff and landing, navigating different airspace environments, and mastering the art of radio communication. And because every virtual pilot needs a plan B, we'll equip you with emergency procedures to handle any in-flight surprises. Safety first, aviators!
Now, let's talk about the trusty companion throughout this guide—the iconic UH-1H Iroquois, or as we like to call it, the Huey. Developed back in the day by Bell Helicopter, this bad boy became famous for its versatility, ruggedness, and reliability. It's the helicopter that ruled the skies during the Vietnam War, delivering troops, evacuating the wounded, and providing close air support. The Huey was the real deal, and we're here to learn from its greatness.
01 Flight Controls, Checklists, Documents, Preflight
Flight Controls
1. Cyclic Control:
Picture the cyclic control as the helicopter's steering wheel. Located between the pilot's legs, it allows for precise control over the helicopter's direction. By tilting the cyclic forward, aft (backward), left, or right, the pilot can adjust the rotor's tilt, causing the helicopter to move in the corresponding direction. Mastering the cyclic control is the key to maneuvering gracefully through the air.
2. Collective Control:
The collective control is like the helicopter's altitude lever. Found on the left side of the pilot's seat, it manages the pitch angle of all the rotor blades simultaneously. Pulling up on the collective control increases the pitch angle, generating more lift and lifting the helicopter off the ground. Pushing it down decreases the pitch angle, reducing lift and allowing the helicopter to descend. The collective control is crucial for controlling the helicopter's altitude during flight.
3. Anti-Torque Pedals:
Located at the pilot's feet, the anti-torque pedals are the helicopter's equivalent of a steering wheel's gas and brake pedals. These pedals control the tail rotor's pitch angle, which counteracts the torque generated by the main rotor's rotation. By manipulating the anti-torque pedals, the pilot can yaw the helicopter left or right, facilitating smooth turns and maintaining directional control.
4. Throttle:
The throttle, typically positioned on the collective control, regulates the engine's power output. It determines the rotor's rotational speed, measured in revolutions per minute (RPM). Increasing the throttle opens the engine's fuel flow, increasing power and rotor RPM, resulting in more lift and thrust. Conversely, reducing the throttle decreases power and rotor RPM. The throttle allows the pilot to manage the helicopter's speed and performance during flight.
Checklists
1. What is a Checklist?
A checklist is a systematic and organized list of tasks and procedures that must be completed before, during, and after a flight. It serves as a comprehensive guide, ensuring that critical steps are followed in a consistent and accurate manner. From pre-flight inspections to emergency procedures, checklists leave no room for oversight or forgetfulness.
2. Application to Specific Aircraft:
Each helicopter has its own unique checklist tailored to its specific model and configuration. Manufacturers and aviation authorities provide detailed checklists, outlining the specific procedures and actions required for safe and efficient operation of that particular aircraft. It covers items such as engine checks, control surface inspections, fuel management, avionics verification, and more. Adhering to the aircraft-specific checklist guarantees that no crucial steps are omitted, enhancing safety and minimizing risks.
3. Importance of Using a Checklist:

This information allows virtual pilots to gain a deeper understanding of the aircraft's characteristics and make informed decisions during flight planning and execution.
3. Limitations and Performance Data:
Understanding an aircraft's limitations is essential for safe and realistic virtual flying. The Operator's Manual outlines the aircraft's operational restrictions, such as maximum speed, altitude limitations, weight limitations, and maneuvering limits. Additionally, it may provide performance data, including, climb rates, cruise speeds, and fuel consumption. These details help virtual pilots operate the aircraft within realistic parameters and enhance the overall simulation experience.
Preflight
In the real world of aviation, "preflighting" an aircraft refers to a comprehensive inspection and preparation process conducted before each flight. It involves carefully examining the aircraft's exterior and interior, checking systems, verifying fuel levels, ensuring proper documentation, and confirming the aircraft's airworthiness. This meticulous preflight procedure ensures that the aircraft is in a safe and operational condition for flight.
However, it's important to note that in most flight simulator games, the preflight process is typically not fully simulated or feasible to the same extent as in real-world aviation. Due to the limitations of the software and the focus on the flying experience, certain aspects of the preflight checklist may be automated or streamlined.

It allows for quick and efficient activation of the radio system, ensuring effective communication during critical moments.
Scanning
...
1. Coordinating the External View and Instrumentation:
Similar to checking your speed while driving a car to ensure you're maintaining the desired speed, the scanning technique in helicopter flying involves continuously cross-referencing the external view with the helicopter's instrumentation. This allows pilots to monitor various parameters and verify that the helicopter is operating as expected.
2. Extensive Information to Scan:
Unlike driving a car, helicopter pilots have a greater amount of information to scan and monitor. They need to pay attention to both the external environment, including the horizon and other aircraft, as well as the instrumentation, which provides critical flight data such as altitude, airspeed, and engine parameters.
3. Avoiding Fixation:
One of the key aspects of the scanning technique is to avoid fixation on a single point, whether it be the outside view or the instrumentation. Pilots should maintain a continuous scan between the horizon and the instrumentation, regularly shifting their focus to ensure they have a comprehensive understanding of the helicopter's flight parameters and the external environment.
4. Importance of Learning the Scanning Technique:
Mastering the scanning technique is essential for helicopter pilots due to the dynamic and multi-dimensional nature of helicopter flight. It helps maintain situational awareness, identify any deviations from the desired flight parameters, and detect potential hazards or obstacles in the surrounding airspace. By continuously scanning and cross-referencing information, pilots can make informed decisions and ensure the safe and efficient operation of the helicopter.
03 Straight & Level, Sight Picture, Airspeed & Altitude
Straight & Level
1. What is Straight and Level Flight?
Straight and level flight refers to a phase where the helicopter maintains a constant heading and altitude, cruising smoothly through the air without ascending or descending. It forms the basis for flying from one point to another and serves as a starting point for various maneuvers.
2. The Art of Stability:
The key to mastering straight and level flight lies in achieving stability. Stability ensures that the helicopter remains in equilibrium, resisting any unwanted deviations in altitude or heading. By maintaining stability, virtual pilots can enhance their control over the aircraft and execute precise maneuvers with ease.
3. Aerodynamics Behind Straight and Level Flight:
To simplify the explanation of aerodynamics involved, think of the helicopter as a balance between opposing forces:
a) Lift: is generated by the rotating blades of the helicopter, creating an upward force that opposes gravity. In straight and level flight, the lift force is balanced with the weight of the helicopter, allowing it to remain at a constant altitude.
b) Thrust: is the forward force generated by the helicopter's engine and rotor system. In straight and level flight, the thrust is precisely balanced with drag (air resistance), resulting in a consistent forward speed.
c) Balance of Forces: The stability of straight and level flight is achieved when the lift force matches the weight and the thrust force equals the drag. This equilibrium ensures that the helicopter maintains a steady altitude and heading.
4. Virtual Piloting Tips:
To excel in straight and level flight in flight simulator games, keep the following tips in mind:
a) Maintain a steady collective pitch and appropriate power setting to achieve the desired lift and thrust balance.
b) Make gentle adjustments to the cyclic control to counteract any deviations in altitude or heading, keeping the helicopter stable.
c) Regularly scan both the external view and the flight instruments to monitor your progress and maintain situational awareness.
Sight Picture
1. What is a Sight Picture?
Sight picture refers to utilizing a fixed position or reference point within the helicopter's cockpit to align with a specific target or achieve desired flight characteristics. Similar to aiming with fixed sights on a gun, sight picture in helicopter flying helps pilots maintain accuracy and stability by establishing a visual reference for their intended path or level flight or when making approaches.
2. Utilizing a Sight Picture:
a) Approaches: During approach maneuvers, we place our line of sight, which is fixed near the center of our vision through the windshield, over the desired target we intend to fly towards. This aligns our visual reference with the intended path, aiding in precise navigation and landing.
b) Straight and Level Flight: In straight and level flight, we place our line of sight on the horizon to establish our sight picture. This enables us to maintain a consistent altitude and heading, keeping the helicopter in stable and level flight.
3. Benefits of a Sight Picture:
By using sight picture techniques, virtual helicopter pilots can enhance their targeting skills and achieve greater precision in their maneuvers. Sight picture provides a visual framework that helps pilots maintain accurate navigation, establish glide slopes during approaches, and achieve stable flight in straight and level conditions.
Airspeed & Altitude
1. The Relationship between Altitude and Airspeed:
In helicopter aviation, altitude and airspeed are interconnected and influence each other. Understanding the coordination required between these two variables is vital for maintaining control and achieving desired flight characteristics.
2. Aerodynamics at Play:
a) Altitude Control: Controlling altitude in a helicopter primarily involves managing the collective control. Increasing collective pitch increases the angle of attack of the rotor blades, generating more lift and allowing the helicopter to climb. Conversely, reducing collective pitch decreases lift, causing the helicopter to descend.
b) Airspeed Control: Airspeed is primarily controlled by adjusting the cyclic control. Tilting the cyclic forward increases the rotor's disc angle, resulting in a greater forward thrust and higher airspeed. Pulling the cyclic aft (backward) decreases the disc angle, reducing forward thrust and decreasing airspeed.
3. Coordination of Controls:
a) Altitude and Airspeed Changes: When making altitude changes, virtual pilots must be aware of the corresponding effect on airspeed. As collective pitch is increased or decreased to adjust altitude, it indirectly affects the helicopter's lift and, consequently, the airspeed. Therefore, pilots need to compensate by adjusting the cyclic control to maintain the desired airspeed.
b) Balancing Inputs: Achieving smooth altitude, airspeed, and even heading control requires coordinated and balanced inputs on the collective, cyclic, and pedal controls. Making sudden or excessive adjustments to one control without compensating with the other can result in unstable flight characteristics or unintended deviations.
4. Virtual Piloting Tips:
a) Smooth Transitions: When transitioning between altitude and airspeed adjustments, aim for smooth and gradual control inputs. This helps maintain stability and minimizes abrupt changes in flight characteristics.
b) Active Monitoring: Continuously monitor the helicopter's response to your control inputs and make any necessary adjustments to maintain the desired altitude and airspeed. Keep a watchful eye on both the flight instruments and external visual cues for a comprehensive understanding of your helicopter's behavior.
