What this profile covers
Inspection, fluid selection and application, holdover assessment, contamination checks, communication, sequencing, and clean-aircraft assurance.
Why it matters
Ground and maintenance activities involve many organizations, handovers, vehicles, tools, procedures, and latent conditions before flight begins. For aircraft de-icing, useful analysis connects the immediate event with exposure, defenses, recurrence, and the wider operating system rather than treating one observation as a final conclusion.
Ramp movement, servicing, loading, de-icing, maintenance execution, and technical-error control.
Understand the subject before interpreting a signal.
In plain language, this profile examines inspection, fluid selection and application, holdover assessment, contamination checks, communication, sequencing, and clean-aircraft assurance.
Build a multi-source picture
- Technical logs, work cards, and handover records
- Ramp, vehicle, servicing, and loading records
- CCTV or ground-surveillance evidence where lawful
- Aircraft data, reports, and physical inspection
Timing, relationships, and recurrence
Relevant recorded context may include engine thrust, brake pressure, autopilot status. Use validated mappings and examine signal relationships over the applicable flight phase.
Do not turn an observation into a conclusion
Aircraft-recorded data usually captures only part of a ground or maintenance sequence; organizational interfaces and physical evidence may be more informative.
Keep controlling material visible
Apply the current approved manuals, procedures, authority requirements, investigation evidence, and validated organizational definitions for any operational decision.
Engine thrust
One or more recorded measures of commanded or produced propulsion; the correct signal depends on engine and aircraft type.
Open parameter guide ↗psi, bar, or %Brake pressure
Hydraulic pressure or command associated with wheel braking; it is not a direct measurement of tyre/runway friction.
Open parameter guide ↗discrete / modeAutopilot status
Engagement and mode states for automatic flight-control systems; useful analysis normally needs more than a single on/off bit.
Open parameter guide ↗From a broad topic to a defensible safety review.
Define
State what aircraft de-icing means for the aircraft, operation, authority, and organization in scope.
Verify
Confirm the provenance, quality, timing, units, completeness, and limitations of every data source used.
Describe
Reconstruct what happened and quantify relevant exposure before discussing causes or corrective action.
Corroborate
Compare flight data with reports, operational context, technical evidence, and authoritative source material.
Test barriers
Identify which preventive, recovery, and consequence-mitigation controls should have worked and how their performance can be measured.
Assure
Assign proportionate action and verify whether the control and safety performance improve without harmful unintended effects.
Questions before conclusions
- Q1
How is aircraft de-icing defined for the aircraft, operation, authority, and organization being reviewed?
- Q2
Which precursors, recorded signals, reports, and external data would confirm the event and describe its context?
- Q3
Which preventive, recovery, and consequence-reduction barriers should work, and where could they weaken?
- Q4
What does recurrence, exposure, severity potential, or change over time show before choosing a safety action?
4 connected event profiles
These are terminology and family connections for exploration—not claims that FDM alone can determine the topic.
Excessive taxi speed
Ground speed remains high for the surface, geometry, visibility, traffic, or operator-defined taxi context.
Open FDM profile ↗FDM-008 · Ground & taxiAsymmetric thrust during taxi
A sustained difference between left and right propulsion parameters appears during taxi movement.
Open FDM profile ↗FDM-118 · Systems & warningsElectrical-system warning or degradation
