A few places to begin, from the aircraft’s story to the people who fly it.
Meet the aircraft
The Katana began as an Austrian Diamond design and developed into the DV20 and DA20 families. The compact side-by-side cockpit, fixed landing gear and T-tail make a recognisable training-aircraft layout. Different developments use different engines and associated equipment. The DA20 should therefore be distinguished from both the four-seat DA40 and earlier Katana variants.
Aircraft background
Wikipedia contributors · Read more ↗The view that made training memorable
Greenspun remembers the Katana’s canopy as its greatest attraction: the low wing and wide view made him feel immersed in the sky. His training aircraft could also be pleasantly quiet with the propeller turning more slowly. On the ground, steering with differential braking took practice, and the small cockpit left him close enough to his instructor for their harness routines to collide. Longer flights revealed compromises.

History & design
A trainer with motorglider roots
Diamond’s early aircraft family grew from the composite HK36 Super Dimona motorglider. Its timeline places the DV20 Katana’s maiden flight in 1991, bringing that design background into a compact two-seat aeroplane.

Austria and Canada in the same family
Diamond established its Canadian operation in London, Ontario, in 1992 and introduced the DA20 to the market. The Austrian DV20 and Canadian DA20 names belong to this shared development story; engine and equipment differences still matter when reading individual pilot accounts.

The view that made training memorable
Greenspun remembers the Katana’s canopy as its greatest attraction: the low wing and wide view made him feel immersed in the sky. His training aircraft could also be pleasantly quiet with the propeller turning more slowly. On the ground, steering with differential braking took practice, and the small cockpit left him close enough to his instructor for their harness routines to collide.
Longer flights revealed compromises. The reclined seat encouraged him to crane forward, leaving his neck uncomfortable, and he found some instruments difficult to read at night. Although he enjoyed training in the Katana, he eventually bought a DA40 for its additional capabilities and rear seats. Making room for his dog Alex was part of that decision.

Kasprzyk came to the Katana through a gliding connection. Long wanted a refresher after limited recent flying, and the two began with a detailed inspection of the newly serviced aircraft. Kasprzyk liked the shoulder and legroom, although his large feet felt cramped near the pedals. Keeping straight while taxiing with differential braking was initially humbling.
Long flew the first circuit before Kasprzyk took the controls. In gusty conditions he found that small stick movements were enough to correct the aircraft, and the canopy helped him follow traffic around Arlington’s busy runways. A long final gave him time to settle the approach before a soft-field landing. He left enthusiastic about the handling and curious to try the aircraft’s glider-like wing in thermals on another flight.

Marsh approached his visit as a chance to experience the pressure placed on an Air Force screening student. He studied the procedures and memorised nearly all the aircraft figures he was given. Early manoeuvres went well, including steep turns and a landing that benefited from watching D’Amico’s demonstration. The instructor’s occasional compliments made the exercise feel encouraging.
Returning to Pueblo exposed how quickly the task could unravel. Marsh lined up with the wrong parallel runway, then misjudged a simulated forced landing and needed the instructor to intervene as speed increased. His eventual touchdown was smooth, but that did not erase the earlier mistakes. He finished with a self-deprecating keepsake for D’Amico and a memorable lesson in the difference between handling an aircraft and managing the whole flight.

The simulator model and controls
The Katana began as an Austrian Diamond design and developed into the DV20 and DA20 families. The compact side-by-side cockpit, fixed landing gear and T-tail make a recognisable training-aircraft layout. Different developments use different engines and associated equipment.
This profile selects SimSolutions Diamond DA20-C1 for MSFS 2020.
How this profile feels
The spring-preload trim mechanism accompanies reversible primary controls. Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.
DA20 pitch trim changes spring preload on the elevator linkage. Pitch-trim relief is off. Autopilot following is off.
Controls and trim
The DA20-C1 uses elevator and aileron pushrods with a cable-operated rudder. Electric pitch trim loads a spring assembly on the elevator pushrod, rather than driving an external trim tab. The C1’s Continental engine and cockpit options are separate from the Rotax-powered A1.
The selected implementation
SimSolutions’ C1 has Continental power and a separately authored cockpit from the Rotax A1 or Aerobask SV.
About the values
The gains are normalized profile settings. They describe the chosen effect balance; hand force depends on the device and its output limits. IAS references are tuning values rather than operating limits. Physical acceptance of this revision remains pending.
Documentary review and sources
These decisions describe the documentary basis and remaining gaps for this revision. Aircraft documentation and a starting setting describe different kinds of evidence.

Force-feedback settings
InheritedThe settings define the profile’s effect balance. Device output limits affect physical hand force.
Starting settings and their rationale
These configured values are starting estimates. The explanations describe what each setting controls; physical validation appears separately below.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring strength | Starting value0.74 | What it controls and whyThe spring-preload trim mechanism accompanies reversible primary controls. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 55 KIAS. |
| Master force gain | Starting value0.85 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| Profile force gain | Starting value0.8 | What it controls and whyThe aerodynamic-load gain is 0.8 with an indicated-speed reference of 110 KIAS. This supplies speed-dependent loading alongside the spring. |
| Force tuning speed/reference | Starting value110 kt | What it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit. |
| Spring response reference speed | Starting value55.0 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
| Aileron force scale | Starting value0.72 | What it controls and whyRoll and pitch aerodynamic scales are 0.72 and 1, respectively. They set the aerodynamic axis balance. No custom spring-travel curve is enabled. |
| Elevator force scale | Starting value1.0 | What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings. |
| Trim feel | Starting valueDisabled | What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement. |
| Trim relief | Starting valueDisabled | What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount. |
| Autopilot follow | Starting valueDisabled | What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel. |
| Autopilot neutral hold | Starting valueDisabled | What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target. |
| Output force limit | Starting value0.55 | What it controls and whyCaps directed-force output. Native spring effects and device limits remain separate. |
All 44 starting settings and their rationale
The settings define the profile’s effect balance. Device output limits affect physical hand force.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring strength | Starting value0.74 | What it controls and whyThe spring-preload trim mechanism accompanies reversible primary controls. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 55 KIAS. |
| Spring deadband | Starting value0.04 | What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner. |
| Profile force gain | Starting value0.8 | What it controls and whyThe aerodynamic-load gain is 0.8 with an indicated-speed reference of 110 KIAS. This supplies speed-dependent loading alongside the spring. |
| Master force gain | Starting value0.85 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| QBlend Enabled | Starting valueEnabled | What it controls and whyAllows baseline spring strength to rise with indicated airspeed where the control law permits it. |
| QSpring Minimum Factor | Starting value0.55 | What it controls and whySets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength. |
| QSpring Start Knots | Starting value8 kt | What it controls and whySets the IAS where the low-speed spring blend starts rising. This is a feel threshold, not a flight limit. |
| Spring response reference speed | Starting value55.0 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
| Force tuning speed/reference | Starting value110 kt | What it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit. |
| Airspeed spring stiffening gain | Starting value0.15 | What it controls and whyThe high-speed spring-stiffening gain is 0.15. It strengthens the permitted spring response above 55 KIAS, with the squared-speed ratio capped at 5. |
| Airspeed spring stiffening limit | Starting value5 | What it controls and whyLimits the squared airspeed ratio used for high-speed spring stiffening; it is not a device-force cap. |
| Aileron force scale | Starting value0.72 | What it controls and whyRoll and pitch aerodynamic scales are 0.72 and 1, respectively. They set the aerodynamic axis balance. No custom spring-travel curve is enabled. |
| Elevator force scale | Starting value1.0 | What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings. |
| Output force limit | Starting value0.55 | What it controls and whyCaps directed-force output. Native spring effects and device limits remain separate. |
| Trim feel | Starting valueDisabled | What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement. |
| Trim relief | Starting valueDisabled | What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount. |
| Elevator Authority | Starting value0 | What it controls and whyDA20 pitch trim changes spring preload on the elevator linkage. Pitch relief is off, with stored authority 0; roll authority is 0. |
| Aileron Authority | Starting value0 | What it controls and whyScales supported roll-trim relief and permitted centre movement. Zero removes roll response. |
| Force Trim Enabled | Starting valueDisabled | What it controls and whyEnables local force trim, separate from aircraft-owned trim and add-on integration qualification. |
| GLoad Enabled | Starting valueEnabled | What it controls and whyAllows load-factor changes to modify permitted spring laws. Passive fly-by-wire feel can suppress it. |
| Rate Damping Enabled | Starting valueEnabled | What it controls and whyEnables rate damping with the configured coefficients and control law. |
| Autopilot follow | Starting valueDisabled | What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel. |
| Autopilot follow authority | Starting value0.1 | What it controls and whySets admitted AP-follow gain, not a percentage of travel. Runtime ownership and input limits still apply. |
| Autopilot neutral hold | Starting valueDisabled | What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target. |
| Autopilot neutral hold strength | Starting value0.6 | What it controls and whySets admitted AP neutral-hold strength; inactive while neutral hold is disabled. |
| Enabled | Starting valueEnabled | What it controls and whyEnables aerodynamic cues; each still needs nonzero strength and its simulator conditions. |
| Gain | Starting value0.35 | What it controls and whySets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings. |
| Gain | Starting value0 | What it controls and whySets high-Mach buffet strength; onset and full-strength thresholds are separate. |
| Gain | Starting value0 | What it controls and whySets flap buffet at the configured position and speed gates. Flap movement texture is separate. |
| Maximum flap index | Starting value3 | What it controls and whySets the final flap index for detent normalization. UP plus three detents uses maximum index3. |
| Minimum flap index | Starting value2 | What it controls and whySets the first flap detent that admits buffet; this is a handle index, not degrees. |
| Gain | Starting value0 | What it controls and whySets gear aerodynamic buffet; movement and ground-contact cues are separate. |
| Shaker Enabled | Starting valueDisabled | What it controls and whyPermits shaker at supported warning conditions; the switch does not establish aircraft equipment. |
| Stick shaker amplitude | Starting value0.5 | What it controls and whySets triggered shaker strength; inactive while the shaker feature is disabled. |
| Enabled | Starting valueEnabled | What it controls and whyEnables ground effects; each still needs its own strength and contact or motion telemetry. |
| Gain | Starting value0.4 | What it controls and whySets rolling texture strength, modified by speed, surface and undercarriage configuration. |
| Gain | Starting value0.25 | What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact. |
| Gain | Starting value0.65 | What it controls and whySets landing-impact strength; landing telemetry and response shape determine the pulse. |
| Gain | Starting value0 | What it controls and whySets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue. |
| Enabled | Starting valueEnabled | What it controls and whyEnables engine cues with nonzero settings and valid running-engine telemetry. |
| Gain | Starting value0.12 | What it controls and whySets estimated engine vibration using configured telemetry and response, not measured cockpit vibration. |
| Enabled | Starting valueEnabled | What it controls and whyEnables accessory cues with configured strengths and observed accessory movement. |
| Gain | Starting value0.12 | What it controls and whySets texture from observed flap movement; a command without movement does not establish the cue. |
| Gain | Starting value0 | What it controls and whySets texture from observed gear movement, separate from aerodynamic and touchdown effects. |
Limits and open questions
- Manual primary trainer controls; no hydraulic boost.
- Exact MSFS trim-neutral mechanism not established by listing; relief off pending that contract.
