Aircraft Handling & Storage

Taxiing and towing, jacking and chocking, refuelling, de-icing/anti-icing fluids, ground power, and parking and storage.

Notes

Handling & storage, summary notes

Main ideas
  • Covers taxiing and towing, jacking and chocking, refuelling and defuelling, ground de-icing/anti-icing, ground power, and parking and storage.
  • Towing: use the approved towbar and tug, a person in the cockpit for the brakes, observers at the extremities, and stay within the nosewheel steering limits, over-steering can damage the gear. Never tow with control locks removed in high wind.
  • JACKING is high-risk: use the approved jacking points and jack type, work sheltered from wind on a level load-bearing floor, raise the jacks evenly and simultaneously, and fit locking collars plus safety stands/trestles as a secondary support. Keep clear beneath and never leave a jacked aircraft unsupported.
  • De-icing removes contamination and anti-icing prevents it; fluids are Types I-IV (Type I unthickened/heated for removal, Types II and IV thickened for holdover, Type III intermediate). Work within holdover times and keep fluid out of intakes, probes and control gaps. The clean-aircraft concept requires critical surfaces free of contamination before flight.
  • Ground power (electrical, hydraulic, pneumatic) must be the correct type and within limits, connected and disconnected in the correct sequence, and the aircraft protected from over-voltage or over-pressure.
  • Refuelling: bond the aircraft, bowser and nozzle together to dissipate static, observe no-smoking/ignition rules, and keep the correct fuel grade, mis-fuelling is a serious hazard.
  • Storage: protect against corrosion and environmental damage, blank openings, fit covers and control locks, preserve engines and systems, and carry out the scheduled storage maintenance.
  • ⚠ Exam trap: jacking demands secondary supports (stands/trestles) and wind shelter; refuelling demands bonding of aircraft, bowser and nozzle.
Key formulas
De-icing fluids
Type I unthickened/remove · II & IV thickened/holdover · III intermediate
Refuelling bonding
aircraft ↔ bowser ↔ nozzle bonded to dissipate static
Jacking
even lift · secondary stands · wind shelter · keep clear beneath
Solved examples
  1. State three precautions specific to aircraft refuelling.

    Bond the aircraft, bowser and nozzle together so no static potential difference can spark; enforce the no-smoking and no-ignition-source rule around the fuelling zone; and confirm the correct fuel grade to prevent mis-fuelling. Fire extinguishers and an escape path should also be available.

  2. Why must a de-icing operator avoid spraying fluid into pitot and static probes?

    The fluid can block or contaminate the probes, corrupting the air-data information (airspeed and altitude) the crew relies on. Probes, sensors, static wicks and control-surface gaps are all kept clear during application for the same reason.

  1. 1. Anti-icing/de-icing fluids are classified as:

    Types I-IV
    Grades A-C
    Classes 1-2
  2. 2. During refuelling the aircraft, bowser and nozzle must be:

    Bonded together
    Kept apart
    Painted
  3. 3. When jacking an aircraft, a secondary support is provided by:

    Safety stands or trestles
    The jacks alone
    The towbar
  4. 4. During towing, the aircraft must be kept within the:

    Nosewheel steering limits
    Maximum taxi speed only
    Fuel limits
  5. 5. De-icing removes contamination; anti-icing:

    Prevents further accumulation
    Adds weight deliberately
    Heats the cabin
  6. 6. De-icing fluid must be kept out of:

    Intakes, probes and control gaps
    The fuselage crown

  7. 7. Type I de-icing fluid is:

    Unthickened, usually heated, for removal
    Thickened for long holdover
    A powder
  8. 8. Ground power must be:

    The correct type and within limits
    Any available supply
    Left connected during flight
  9. 9. The clean-aircraft concept requires:

    Critical surfaces free of contamination before flight
    A freshly painted airframe
    Full fuel tanks
  10. 10. During storage, engine and system openings are:

    Blanked and the aircraft preserved
    Left open for ventilation
    Filled with fluid
