Meet DFS SG 38 Schulgleiter
The SG 38 is a single-seat primary glider from 1938, with an exposed seat on a braced structure beneath the wing. Deutsches Museum describes it as a widely built training glider from the period when students began in single-seat aircraft. Simplicity, repairability and low construction cost shaped that approach to instruction.
The museum also records an optional cockpit fairing called a boat, used to introduce a more enclosed cockpit. Its own example was built by a flying club in 1954 and used for training until 1956, when that club moved to two-seat instruction.
History & design
Learning alone, a short flight at a time
The SG 38 belongs to an earlier approach to glider training in which the pupil flew alone from the beginning. Deutsches Museum dates the design to 1938 and describes a machine intended to be inexpensive, easy to repair and straightforward to fly. Thousands were built. Its exposed seat and simple structure reflect that teaching method, rather than a missing cockpit.
After the war, two-seat instruction increasingly replaced solo primary training. The museum's example was built by the Rastatt flying club and used for training from 1954 to 1956, then retired when the club adopted two-seaters. An optional seat fairing, nicknamed a boat, helped prepare pupils for enclosed cockpits.

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 value0.64 | What it controls and whyThis profile uses reversible-control loading for DFS SG 38 Schulgleiter. The baseline spring is 0.64. Its low-speed blend reaches baseline strength at 20 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 value1 | What it controls and whyThe aerodynamic-load gain is 1 with an indicated-speed reference of 40 KIAS. This supplies speed-dependent loading alongside the spring. |
| Force tuning speed/reference | Starting value40 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 value20.0 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 | 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 47 starting settings and their rationale
The settings define the profile’s effect balance. Device output limits affect physical hand force.

40 KIAS is a selected control-feel reference for Cockspur DFS SG38 Schulgleiter, not published cruise TAS, V-speeds or an operating limit. q-blend/deadband/drop thresholds are derived engineering estimates.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Force tuning speed/reference | Starting value40 kt | What it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit. |
| QSpring Start Knots | Starting value5.6 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 value20.0 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
| Full Speed Ref Knots | Starting value20.0 kt | What it controls and whyA stored parameter in this profile. Its effect depends on the associated feature and control law; it is not a measured aircraft force. |
| Fade Kts | Starting value12.0 | What it controls and whyA stored parameter in this profile. Its effect depends on the associated feature and control law; it is not a measured aircraft force. |
Accessory motion/ground/engine textures inherit existing current estimates; enablement follows reviewed equipment and qualified standard positions, not new actuator or pressure signals.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Gain | Starting value0 | 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. |
| Undercarriage | Starting value0 | What it controls and whyA stored parameter in this profile. Its effect depends on the associated feature and control law; it is not a measured aircraft force. |
| Gain | Starting value0 | What it controls and whySets estimated engine vibration using configured telemetry and response, not measured cockpit vibration. |
Exact configured values with software explanations. Force magnitudes remain editable estimates; disabled features retain inactive values.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring deadband | Starting value0.04 | What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner. |
| 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. |
| Airspeed spring stiffening gain | Starting value0.3 | What it controls and whyThe high-speed spring-stiffening gain is 0.3. It strengthens the permitted spring response above 20 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. |
| 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 value0.3 | What it controls and whyThe profile uses the trim behaviour configured below. Pitch relief is off, with stored authority 0.3; 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 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 value0.4 | 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 value6 | 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. |
