Chapter 6 - Aircraft Critical Surface Contamination Examination Questions

1.0  Air Law, The Clean Aircraft Concept

1.01  Frost, ice or snow on top of deicing or anti icing fluids

  1. is not considered as adhering to the aircraft and a take off may be made.
  2. must be considered as adhering to the aircraft and a take off should not be attempted.
  3. is only considered as adhering to the aircraft when Vr speeds are below 100 kt.
  4. is not considered as adhering if the aircraft has been de iced and then anti iced.

1.02  Where conditions are such that frost, ice or snow may reasonably be expected to adhere to the aircraft, no person shall take off or attempt to take off in an aircraft unless

  1. it has been de iced.
  2. it has been inspected immediately prior to take off to determine whether any frost, ice or snow is adhering to any of its critical surfaces.
  3. its skin temperature is warm enough to ensure that adhering frost, ice or snow will slide off on take off.
  4. its power and runway length are sufficient to allow acceleration to Vr plus 10% before rotation.

1.03  Prior to take off, the PIC cannot confirm that the aircraft is "clean". Take off

  1. may be commenced provided the maximum holdover time has not been exceeded.
  2. may be commenced provided the anti ice fluid used was of the type that prevents ice or snow from sticking to the critical surfaces.
  3. may be commenced provided the amount of frost, ice, or snow does not exceed that specified in the company operations manual.
  4. must not be attempted until confirmation is obtained that the aircraft is clean.

1.04  One engine is kept running during a quick turn around in icing conditions because you are unable to restart it with existing internal or external power. When taxiing for take off, you are advised that there is a significant amount of wet snow on the aircraft. As your operating instructions require both engines to be shut down for deicing, you should

  1. take off but delay rotation until Vr plus 10%.
  2. take off as wet snow will slide off as the aircraft becomes airborne.
  3. taxi back to the apron, shut down the engine you are able to restart and have the critical surfaces carefully de iced.
  4. cancel the flight until proper equipment is available or necessary repairs made.

1.05  The only positive assurance that an aircraft is "clean" prior to take off can be achieved by

  1. confirmation from the crew chief that the fluid used has the required holdover time.
  2. ensuring the aircraft is not subjected to excessive ground delays.
  3. close inspection by the PIC or designated flight crew member.
  4. ensuring take-off is within the applicable holdover time table.

1.06  Who may inspect an aircraft immediately prior to take off to determine whether any frost, ice or snow is adhering to any of its critical surfaces?

The PIC and

  1. a flight crew member of the aircraft designated by the PIC to carry out the inspection.
  2. the operations officer.
  3. the deicing crew.
  4. a person designated by the operator who has received the required surface contamination training.
  5. any Aircraft Maintenance Engineer.
  1. A, B, C, D, E.
  2. A, B, C, D.
  3. A, B, C.
  4. A, D.

1.07  When a crew member of an aircraft observes frost, ice or snow adhering to the wings of an aircraft before take off, the crew member

  1. shall immediately report that observation to the PIC.
  2. need not report that observation if the aircraft has recently been de iced.
  3. shall immediately report that observation to the designated crew member.
  4. unless designated, need not report that observation.

1.08  Before commencing take off the PIC is advised that there is frost, ice or snow adhering to the wings of the aircraft.

The PIC

  1. may take off without a further wing inspection if the aircraft has been recently de iced.
  2. shall request a go/no go decision from company operations.
  3. shall request the deicing crew to inspect the wings before take off.
  4. or another flight crew member designated by the PIC shall inspect the wings before take off.

1.09  No person shall commence a flight in an aircraft

  1. unless it has been de iced if frost, ice, or snow conditions exist.
  2. unless assured that adhering frost, ice or snow will slide off on take off.
  3. if frost, ice, or snow is adhering to any of its critical surfaces.
  4. if frost, ice, or snow adhering to the critical surfaces cannot be removed on take off by the aircraft deicing systems.

1.10  An air carrier shall provide training to crew members on the adverse effects of aircraft surface contamination

  1. biannually.
  2. on initial hiring and annually.
  3. biennially.
  4. on initial hiring only.

1.11  Persons other than crew members who require annual training on the adverse effects of aircraft surface contamination are those

  1. designated by the air carrier to carry out inspections in relation to the identification, reporting and inspection of surface contamination.
  2. involved in flight operations safety awareness programs.
  3. baggage handlers and refuellers who service the air carrier's aircraft.
  4. designated by the air carrier to de ice its aircraft.

1.12  Candidates taking the training program on adverse effects of aircraft surface contamination

  1. need not have their results recorded.
  2. shall be tested orally on the use of deicing and anti icing equipment.
  3. shall be tested to verify they understand and are able to apply the concepts taught.
  4. shall write an examination on the concept and use of deicing and anti icing equipment.

1.13  Persons who are involved in flight operations and who are not required to undergo periodic training on the adverse effects of aircraft surface contamination shall be

  1. advised of their responsibility for inspection of surface contamination.
  2. designated as backup for identification and reporting of surface contamination.
  3. tested on their understanding of reporting and inspection concepts.
  4. given a safety awareness program on the subject.

1.14  A flight attendant observes snow adhering to the wings of an aircraft. The flight attendant

  1. shall report that observation to the head flight attendant.
  2. shall immediately report that observation to the PIC.
  3. need not report that observation if the aircraft was de iced.
  4. need not report that observation if the aircraft was anti iced.

1.15  The PIC notes that frost caused by cold soaking fuel is adhering to the underside of the wings. Take off may

  1. not be attempted until the aeroplane is de iced.
  2. not be attempted under any circumstances as the frost, if removed, will quickly reform.
  3. be made at the discretion of the PIC.
  4. be made provided it is conducted in accordance with the aircraft manufacturer's instruction.

1.16  A take off with frost adhering to the underside of a wing may

  1. not be made under any circumstance.
  2. be made if it is conducted in accordance with the aircraft manufacturer's instructions.
  3. be made providing the grains of frost are no larger than .004 inches in diameter.

  2. A flight crew member of the aircraft who is designated by the PIC.
  3. A person designated by the operator of the aircraft who has received the required surface contamination training.
  4. All of the above.

1.18  Select the correct statements regarding the use of representative aircraft surfaces.

  1. The operator's Ground Icing Operation Program must specify the conditions under which they may be used to comply with the Pre Take Off Inspection.
  2. They must be areas that can be clearly observed by the flight crew.
  3. Their surfaces should not be altered in any way that makes them appear different from the surrounding surfaces.
