HOW IT CAME TO BE

History & design

How the Il-18 family evolved

The Il-18 developed through A, B, V, E and D versions as the cabin, structure and onboard systems changed. Nemeth describes the early A as an 80-seat aircraft, followed by the strengthened B and later rearrangements for greater capacity. The D took the family toward longer non-stop sectors through increased fuel capacity. Its add-on represents a late, upgraded D, so descriptions of early passenger layouts or fuel systems should not be treated as universal across the family.

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.

Speeds and limits
Inherited

The indicated-speed references set the profile response scale; they are separate from aircraft operating limits.

Force-feedback settings
Inherited

The 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.

Estimated starting settings · revision 1
SettingStarting valueWhat it controls and why
Spring strengthStarting value0.74 What it controls and whyElevator controls: Mechanical, with loading spring. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 95 KIAS.
Master force gainStarting value0.85 What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits.
Profile force gainStarting value0.8 What it controls and whyThe aerodynamic-load gain is 0.8 with an indicated-speed reference of 190 KIAS. This supplies speed-dependent loading alongside the spring.
Force tuning speed/referenceStarting value190 ktWhat 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 speedStarting value95.0 ktWhat it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.
Aileron force scaleStarting 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 scaleStarting value1 What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings.
Trim feelStarting valueEnabled What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement.
Trim reliefStarting valueEnabled What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount.
Autopilot followStarting valueDisabled What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel.
Autopilot neutral holdStarting valueDisabled What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target.
Output force limitStarting 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

SettingStarting valueWhat it controls and why
Force tuning speed/referenceStarting value190 ktWhat it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit.
QSpring Start KnotsStarting value26.6 ktWhat 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 speedStarting value95.0 ktWhat it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.
Full Speed Ref KnotsStarting value95.0 ktWhat 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 KtsStarting value57.0 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.

Estimated starting settings · revision 1
SettingStarting valueWhat it controls and why
GainStarting value0.12 What it controls and whySets texture from observed flap movement; a command without movement does not establish the cue.
GainStarting value0.12 What it controls and whySets texture from observed gear movement, separate from aerodynamic and touchdown effects.
UndercarriageStarting 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.
GainStarting value0.12 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.

Estimated starting settings · revision 1
SettingStarting valueWhat it controls and why
Spring deadbandStarting value0.045 What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner.
QBlend EnabledStarting valueEnabled What it controls and whyAllows baseline spring strength to rise with indicated airspeed where the control law permits it.
QSpring Minimum FactorStarting value0.5 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 gainStarting value0.15 What it controls and whyThe high-speed spring-stiffening gain is 0.15. It strengthens the permitted spring response above 95 KIAS, with the squared-speed ratio capped at 5.
Airspeed spring stiffening limitStarting value5 What it controls and whyLimits the squared airspeed ratio used for high-speed spring stiffening; it is not a device-force cap.
Trim feelStarting valueEnabled What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement.
Trim reliefStarting valueEnabled What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount.
Elevator AuthorityStarting value0.3 What it controls and whyRight-aileron trim: Electric. Pitch authority 0.3 provides load relief and permitted centre movement; roll authority is 0.09.
Aileron AuthorityStarting value0.09 What it controls and whyScales supported roll-trim relief and permitted centre movement. Zero removes roll response.
Force Trim EnabledStarting valueDisabled What it controls and whyEnables local force trim, separate from aircraft-owned trim and add-on integration qualification.
GLoad EnabledStarting valueEnabled What it controls and whyAllows load-factor changes to modify permitted spring laws. Passive fly-by-wire feel can suppress it.
Rate Damping EnabledStarting valueEnabled What it controls and whyEnables rate damping with the configured coefficients and control law.
Autopilot followStarting valueDisabled What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel.
Autopilot follow authorityStarting 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 holdStarting valueDisabled What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target.
Autopilot neutral hold strengthStarting value0.6 What it controls and whySets admitted AP neutral-hold strength; inactive while neutral hold is disabled.
EnabledStarting valueEnabled What it controls and whyEnables aerodynamic cues; each still needs nonzero strength and its simulator conditions.
GainStarting value0.35 What it controls and whySets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings.
GainStarting value0 What it controls and whySets high-Mach buffet strength; onset and full-strength thresholds are separate.
GainStarting value0 What it controls and whySets flap buffet at the configured position and speed gates. Flap movement texture is separate.
Maximum flap indexStarting value2 What it controls and whySets the final flap index for detent normalization. UP plus three detents uses maximum index3.
Minimum flap indexStarting value2 What it controls and whySets the first flap detent that admits buffet; this is a handle index, not degrees.
GainStarting value0 What it controls and whySets gear aerodynamic buffet; movement and ground-contact cues are separate.
Shaker EnabledStarting valueDisabled What it controls and whyPermits shaker at supported warning conditions; the switch does not establish aircraft equipment.
Stick shaker amplitudeStarting value0.5 What it controls and whySets triggered shaker strength; inactive while the shaker feature is disabled.
EnabledStarting valueEnabled What it controls and whyEnables ground effects; each still needs its own strength and contact or motion telemetry.
GainStarting value0.4 What it controls and whySets rolling texture strength, modified by speed, surface and undercarriage configuration.
GainStarting value0.25 What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact.
GainStarting value0.65 What it controls and whySets landing-impact strength; landing telemetry and response shape determine the pulse.
GainStarting value0 What it controls and whySets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue.
EnabledStarting valueEnabled What it controls and whyEnables engine cues with nonzero settings and valid running-engine telemetry.
EnabledStarting valueEnabled What it controls and whyEnables accessory cues with configured strengths and observed accessory movement.
Limits and open questions
  • Airliner size/engine count do not establish hand force. Procedures/navigation PDFs failed acquisition and are not claimed reviewed.
  • Physical FFB, installed add-on matching and cross-platform runtime acceptance are deferred. No certification or simulator-vendor endorsement is implied.
  • Unqualified physical AP following, neutral hold, force trim, native force additions, hardware failures and input compensation are disabled.

Physical validation

No physical force validation is recorded in this public catalogue for this revision. Documentary review and software checks do not establish how a particular device feels.
