Helicopter Log Payload Cycle Minute

Screen complete log-haul cycles from caller already-established available payload, rigging, green density and cycle duration; does not compute aircraft performance, approve lifts or certify external-load safety.

Description

A log-haul scenario separates wood payload from rigging mass and complete cycles from ideal continuous throughput.

A log-haul scenario separates wood payload from rigging mass and complete cycles from ideal continuous throughput. Available aircraft payload must already have been established independently.^[1]

When to use Helicopter Log Payload Cycle Minute

Use this tool to screen complete log-haul cycles from caller already-established available payload, rigging, green density and cycle duration; does not compute aircraft performance, approve lifts or certify external-load safety.

Gather the tree inventory, plot measurements or model parameters. Check diameter, area, time and moisture conventions; keep paired observations aligned.

How to use Helicopter Log Payload Cycle Minute and understand its results

Gather the tree inventory, plot measurements or model parameters. Check diameter, area, time and moisture conventions; keep paired observations aligned.
Enter callerAvailableExternalPayloadKg, riggingMassKg, logGreenDensityKgPerM3, cycleTimeMinutes, expectedOperatingMinutes using the field table and calculation rules, then run the tool.
Read modelWoodPayloadM3PerCycle, completeCycleCount, completeCycleWoodVolumeM3, idealContinuousThroughputM3PerHour. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
callerAvailableExternalPayloadKg	Caller available external payload kg	number	Required
riggingMassKg	Rigging mass kg	number	Required
logGreenDensityKgPerM3	Log green density kg per m3	number	Required
cycleTimeMinutes	Cycle time minutes	number	Required
expectedOperatingMinutes	Expected operating minutes	number	Required

Use positive declared payload, green density and cycle minutes, plus nonnegative rigging no greater than payload and operating minutes. Return per-cycle volume, safe-integer complete cycles, complete-cycle volume and ideal m³/hour.

wood m³/cycle=(available payload−rigging)/green density; complete cycles=floor(operating minutes/cycle minutes)

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
modelWoodPayloadM3PerCycle	Model wood payload m3 per cycle	number
completeCycleCount	Complete cycle count	number
completeCycleWoodVolumeM3	Complete cycle wood volume m3	number
idealContinuousThroughputM3PerHour	Ideal continuous throughput m3 per hour	number

Limitations and assumptions

Aircraft performance and flight conditions are not solved. The arithmetic does not approve lifts or establish external-load safety.

Numeric inputs and returned numeric values must be finite; an unrepresentable returned value produces an error. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Average Skidder Turn Cycle Time: Audit complete observed skidder phase cycles and actual payload throughput, not average phase duration or a generic travel-time estimate; no travel terrain, load capacity or operator safety inferred. For a complementary task, use Harvest System Productivity m³/PMH: Separate observed delivered-volume productivity per productive/scheduled machine hour and utilization; operational delays remain explicit and no machine capability guarantee.
