#2. DURALUMIN alloys :1 have an aluminium-copper base.2 have an aluminiummagnesium base.3 are easy to weld.4 are difficult to weld.5 have a good thermal conductivity.6 have a poor air corrosion resistanceThe combination regrouping all the correct statements is :
#3. If the profile grooves or the tread of a new aircraft tyre are worn, the tyre can be:
#4. The purposes of the oil and the nitrogen in an oleo-pneumatic strut are :
#5. When consciously breathing fast or hyperventilating due to high arousal or overstress, the carbon dioxide level in the blood is lowered, resulting in:
When hyperventilating, the level of carbon dioxide in the blood drops, which reduces the drive to breathe. This can cause vasoconstriction (narrowing of blood vessels), impairing the delivery of oxygen to the tissues, despite an increased intake of oxygen. This makes it harder for the oxygen to diffuse into cells, worsening the effects of hypoxia.
#6. The standby power supply powering the standby artificial horizon must be operable on board any aircraft of more than 5700 kg or more than 9 passengers during at least :
#7. A slaved directional gyro derives it’s directional signal from?
#8. Locators are: 1. High powered NDBs used for en route and airways. 2. Low powered NDBs used for airfield airfield runway approach. 3. Beacons with a usually range of 10 to 250 nm. 4. Beacons with a usually range of 10 to 25 nm. The combination regrouping all of the correct statements is?
#9. Regarding a safe life structure: 1. will only fail after a known number of operations or hours of use. 2. should not fail until a predicted number of fatigue cycles has been achieved. 3. has a programmed inspection cycle to detect and rectify faults. 4. is changed before its predicted life is reached.
A safe life structure is designed to endure a predetermined number of fatigue cycles, such as pressurization events or landings, and is removed from service before reaching that limit to avoid the risk of failure. While inspections are not the primary safety measure, a programmed inspection cycle is often included to detect any unexpected issues during its operational life.
#10. A fail safe structure: 1. has a programmed inspection cycle to detect and rectify faults. 2. is changed before its predicted life is reached. 3. has redundant strength which will tolerate a certain amount of structural damage. 4. is secondary structure of no structural significance.
A fail-safe structure is designed with redundant strength, allowing it to withstand structural damage by transferring loads to alternate paths if one part fails. This ensures the aircraft can continue to operate safely until the issue is identified and repaired during a programmed inspection cycle. It is not changed before its life is reached, nor is it secondary or insignificant.
#11. Station numbers (Stn) and water lines (WL) are:
Station numbers (Stn) and water lines (WL) are used as a reference system to accurately locate structural components and systems on an aircraft. They provide a standardised method for identifying positions along the fuselage, wings, and vertical sections based on fixed reference points defined by the manufacturer.
#12. A torsion box:
A torsion box is a structural unit within the wing, formed by the front and rear spars, wing skin, ribs, and stringers, designed to resist both bending and twisting (torsional) loads. It gives the wing the necessary stiffness and strength under aerodynamic forces.
#13. The most likely cause of brake fade is:
Brake fade occurs when excessive heat causes the brake pads and rotors to lose friction efficiency, resulting in a reduction in braking power. Continuous or hard braking builds up heat, which affects the materials’ ability to generate friction, making overheating the most likely cause of brake fade.
#14. A pitot intake forms a ____________ duct______ the fan to ensure that the airflow ______ to ________ and achieves a ________
#15. What does a stick pusher do?
A stick pusher is a safety device that automatically pushes the control column forward when the aircraft reaches a critical angle of attack (AoA) close to stall. This action helps the pilot reduce AoA and prevent a stall by lowering the nose without relying solely on pilot reaction.
#16. The ‘torsion box’ of a modern aircraft wing structure consists of:
#17. During take-off, the thrust of a fixed pitch propeller:
#18. Which of the following is obligating for members of ICAO?
Member states are required to notify ICAO of any differences in their national regulations from the standards set in the Annexes to the Chicago Convention. This helps maintain global standards for aviation safety, security, and efficiency.
#19. Which Annex to the Chicago Convention covers dangerous goods carried in aircraft?
Annex 18: Safe Transport of Dangerous Goods by Air
#20. If you are flying IFR in IMC conditions and you experience a total communications failure, you should:
In IMC. If a failure occurs in IMC:
- When Being Radar Vectored:
- Proceed directly to rejoin the current flight plan route.
- Squawk A7600 (indicating radio communication failure).
- Follow the applicable minimum flight altitude.
- If En Route in a Radar-Controlled Area:
- Squawk A7600 and maintain the current flight plan.
- Continue for 7 minutes, then adjust speed and altitude as per the filed flight plan.
- If En Route Outside Radar-Controlled Areas:
- Maintain the current flight plan for 20 minutes after failing to report over a compulsory reporting point.
- Adjust speed and altitude thereafter according to the filed flight plan.
- This 20-minute period allows the air traffic control officer (ATCO) time to manage any potential conflicts during the transition back to the filed flight plan profile.
#21. What are you required to do if you become aware that your transponder has failed?
If you become aware that your transponder has failed, you are required to inform ATC immediately. They will provide instructions or clearances to proceed safely.
#22. When an aircraft is being refueled, the refueling must be stopped if a jet aircraft crosses with in a distance of:
Fuelling operations shall cease when a turbo-jet aircraft manouvres so as to bring the rear jet outlets within 43 meters of the fuelling equipment or the aircraft.
#23. For aircraft flying over the high seas, which rules shall be in force?
The rules for aircraft flying over the high seas are established under the Convention on International Civil Aviation (ICAO). According to Article 12 of the Chicago Convention, the airspace over the high seas is considered international airspace, meaning the rules in force are those established under the Convention. These rules govern the operation of aircraft in these areas, ensuring uniform safety and operational standards, regardless of the state under which the aircraft operates.
#24. While refueling is in progress, no naked light be brought within _____ mts:
Smoking, the use of any appliance employing naked flame, or any appliance capable of producing a spark, or anything that could ignite fuel vapors, shall not be permitted within 30 meters of the aircraft or fueling equipment.
#25. During the transmission of numbers containing a decimal point:
The correct procedure for transmitting numbers containing a decimal point is that the term “Decimal” must always be transmitted. According to ICAO guidelines, this ensures clarity and avoids misunderstandings, particularly in complex or noisy communication environments. The term “Decimal” is used to distinguish the decimal point clearly from other numbers.
