The interactive simulator needs JavaScript and WebGL. The reference material it contains is summarised here.
- Collective
- The lever at the pilot's left hand. It changes the pitch angle of every main rotor blade at once — collectively, which is where the name comes from — so it changes how much total lift the rotor makes. Controls altitude and total power.
- Cyclic
- The stick between the pilot's knees. It changes each blade's pitch cyclically — once per revolution — which tilts the whole rotor disc. Tilt the disc and you tilt the lift, and the aircraft goes that way.
- Cyclic X / Cyclic Y
- WARDOGS' own names in the keybind menu. X is pitch (nose up and down); Y is roll (bank left and right).
- Yaw / pedals / anti-torque
- The tail rotor, worked by foot pedals in a real aircraft. It swings the nose left and right about the vertical axis without changing where the aircraft is travelling.
- Rotor disc
- The circle the blades sweep out. Almost every explanation of helicopter flight is really a statement about which way the disc is tilted.
- Lift vector
- The single force the rotor makes, pointing straight out of the disc. Tilt the disc and that force splits into a vertical part still holding you up and a horizontal part pulling you along.
- Attitude
- The aircraft's angle relative to the horizon — nose attitude (pitch) and banked attitude (roll).
- Bank
- Rolling the aircraft so the disc tilts to one side. Bank is what turns a helicopter; the pedals only point the nose.
- Spilling lift
- Tilting the disc so far that too much of the lift points sideways and the aircraft sinks or dives in that direction.
- Inertia
- Speed resists a change of direction. Rule of thumb: double the speed and the turn radius roughly quadruples.
- Crab
- Flying with the nose pointed somewhere other than the direction of travel. A large deliberate crab is what makes a J-hook brake so hard — the fuselage is presented to the airflow.
- Slip / skid
- Slip is yaw opposite the bank; skid is yaw into the bank. Both point the nose independently of the turn.
- Weathercocking
- The nose wanting to swing back into the relative airflow, like a weathervane. Very obvious in backwards flight.
- Correlation
- Cologne TM's word for the link between what your hands do and what the aircraft does. Building it is the actual point of the practice drills.
- Flare
- Raising the nose near the ground to bleed off speed without climbing. Collective down, nose up just enough to hold height while the speed washes off.
- J-hook
- Arrive fast and low alongside the landing zone, dump the collective, roll toward the spot and hold pedal so the tail swings while the nose stays on it. The turn is the airbrake.
- Quick stop
- Fast and low to a standstill in one movement without climbing. The building block a J-hook is made from.
- Run-on landing
- Landing with a little forward or backward speed still on and sliding to a stop. Has to be slow or you break the airframe.
- Pedestal landing
- Setting down on a raised surface — a rooftop or a tower.
- Turning about a point
- Flying a constant-radius circle around a fixed object while holding the nose on it with the pedals. Cologne TM rates it the single best all-round drill — it is also exactly the gunship orbit.
- Nap of the earth
- Flying down in the terrain rather than above it, using ground and buildings to break line of sight. Also called terrain masking.
- AGL / ASL
- Above ground level — use it for drops and crates. Above sea level — use it for terrain and obstacle clearance.
- Pitch ladder
- The attitude scale in the middle of the HUD. The arrows slide down the ladder as the nose drops.
- Collective indicator
- The vertical bar low on the HUD. Rising means a climbing input, falling means descending, and centred means you are holding what you have.
- Bingo fuel
- The fuel state at which you have to turn for home.
- LZ
- Landing zone. Choosing a good one matters more than flying the approach perfectly.
- Hot zone
- The contested objective area. Everything you do inside it pays double, passenger drops included.
- FOB
- Forward operating base. What your supply runs feed, and what the enemy mortars strip of building supplies.
- Rifle aim
- The community's name for putting yaw on the mouse, so you point the aircraft's nose the way you would point a rifle.
