2. Which Kenyan airline is the national flag carrier of Kenya?
Kenya Airways is the national flag carrier of Kenya, operating international and domestic flights; Jambojet and Safarilink are domestic carriers, and Precision Air is based in Tanzania.
3. Which four forces act on an aircraft during steady, level flight?
The four aerodynamic forces are lift (upward), weight (downward due to gravity), thrust (forward from the engine) and drag (rearward aerodynamic resistance); these balance in steady, level flight.
4. What part of an airplane mainly provides lift?
Airplane wings are shaped to create a pressure difference above and below, producing lift that supports the aircraft in flight.
5. Which instrument shows an aircraft's height above mean sea level?
The altimeter measures atmospheric pressure and displays altitude above mean sea level, which pilots use to maintain safe vertical separation and follow procedures.
6. What is the unit commonly used to measure aircraft speed?
Aviation uses knots (nautical miles per hour) as the standard unit for airspeed and ground speed worldwide, including in Kenya.
7. What is the job of an air traffic controller?
Air traffic controllers ensure safe, orderly, and efficient flow of air traffic by giving instructions and clearances to pilots for take‑off, landing, and route separation.
8. Which Kenyan authority is responsible for civil aviation regulation?
KCAA is the regulatory body for civil aviation in Kenya, overseeing safety, licensing, and airport operations among other responsibilities.
9. What does the term 'preflight check' mean?
Preflight checks are performed by pilots and crew to verify the aircraft's systems, fuel, and safety equipment are in proper condition before departure.
10. Which aircraft control surface changes the aircraft's roll (bank) left or right?
Ailerons, located on the trailing edges of the wings, move opposite each other to roll the aircraft about its longitudinal axis; the rudder controls yaw and the elevator controls pitch.
11. What is the purpose of flaps on an airplane wing during landing?
Extending flaps increases wing camber, producing more lift at lower speeds and increasing drag to help slow the aircraft for a safer approach and landing.
12. Which Kenyan airport is the main international gateway to the country?
JKIA in Nairobi is Kenya's largest and main international airport handling most international flights to and from the country.
13. What does the aircraft registration prefix '5Y' indicate when seen on a plane?
National registration prefixes identify the country of registration; '5Y' is the international prefix allocated to Kenya for civil aircraft registration.
14. Which weather condition is most critical to check before a flight because it can cause turbulence and visibility problems?
Thunderstorms bring severe turbulence, lightning, heavy rain, wind shear and poor visibility, all of which are hazardous to safe flight operations.
15. Which part of the airport is used for take-off and landing?
Runways are long, prepared surfaces specifically used by aircraft for take-off and landing; aprons are where aircraft park and terminals handle passengers.
16. What is the main purpose of a black-and-white striped marking at the runway threshold?
Threshold markings identify the beginning of the runway available for landing, helping pilots align and judge touchdown points during approach.
17. Which international organization sets standards and recommended practices for global civil aviation?
ICAO, a UN specialized agency, develops international standards and recommended practices for aviation safety, security and operations used by member states including Kenya.
18. What is the correct action for a passenger when the 'fasten seatbelt' sign is illuminated?
When the seatbelt sign is on, passengers must stay seated with belts fastened for safety due to turbulence, takeoff, landing, or instructions from crew.
19. Which of these is an example of a rotorcraft?
A helicopter is a rotorcraft that produces lift and thrust using rotating blades (rotors); gliders and fixed-wing airliners are not rotorcraft.
20. What does the term 'airworthiness' mean for an aircraft?
Airworthiness means the aircraft complies with maintenance standards and regulatory requirements and is fit to fly safely.
21. Which navigation aid provides pilots with directional information using radio signals from a ground station?
A VOR is a radio navigation system that transmits signals pilots use to determine bearing to or from a ground station for en-route navigation and approaches.
22. What is the main responsibility of cabin crew on a passenger flight?
Cabin crew are trained to manage passenger safety, conduct safety briefings, operate emergency equipment, and assist during evacuations or medical events.
23. Which phrase describes the legal permission for a person to act as a pilot in command of an aircraft?
A pilot licence (or certificate) issued by the aviation authority certifies that a person has met training, testing and medical requirements to act as pilot in command.
24. What should a pilot do if visibility is below the minimum required for the intended approach?
If visibility is below minima, the safe option is to go around, hold, or divert to another airport rather than attempt a risky landing; safety procedures and regulations govern this.
25. Which form of training would best prepare a student for becoming an aircraft maintenance technician in Kenya?
Formal training approved by the Kenya Civil Aviation Authority ensures the technician meets regulatory standards, gains practical skills, and is eligible for licensing.
26. Why is fuel management important on every flight?
Proper fuel planning ensures safety by providing sufficient fuel for the flight, unexpected delays, holding, or diversion to alternate airports according to regulations.
27. What is aviation?
Aviation covers the design, production and operation of aircraft and everything involved in flight, not ships, trains or road transport.
28. Which Kenyan authority is responsible for regulating civil aviation?
The Kenya Civil Aviation Authority (KCAA) oversees civil aviation safety, licensing, aircraft registration and regulation in Kenya.
29. Which four forces act on an aircraft in flight?
The four aerodynamic forces are lift (upward), weight (downward), thrust (forward) and drag (backward); they determine an aircraft's motion.
30. What is the primary function of an aircraft's control surfaces (ailerons, elevator, rudder)?
Control surfaces alter airflow to change roll, pitch and yaw so the pilot can steer and control the aircraft.
31. What do runway numbers represent?
Runway numbers correspond to the runway's magnetic heading rounded to the nearest 10 degrees and expressed as two digits (e.g., 09 = 090°).
32. What is the IATA code for Jomo Kenyatta International Airport in Nairobi?
The IATA code for Jomo Kenyatta International Airport in Nairobi is NBO. WIL is Wilson Airport; Mombasa is MBA.
33. Which unit is commonly used worldwide to measure aircraft speed?
Aircraft speed is usually measured in knots (nautical miles per hour) in international aviation practice.
34. Which Nairobi airport is mainly used for domestic, regional and general aviation flights?
Wilson Airport in Nairobi handles most domestic, regional and general aviation flights, while Jomo Kenyatta handles major international traffic.
35. Which principle is commonly used to explain part of how lift is generated on an aircraft wing?
Bernoulli's principle describes how faster airflow over the top of the wing creates lower pressure compared with the underside, contributing to lift.
36. Which licence allows a pilot to be paid to carry passengers commercially?
A Commercial Pilot License (CPL) permits the holder to be compensated for carrying passengers or cargo; a Private Pilot License (PPL) does not.
37. What is the main role of Air Traffic Control (ATC)?
ATC's core job is to keep aircraft safely separated, sequence traffic and provide pilots with instructions and information.
38. Which cockpit instrument shows an aircraft's altitude above sea level?
The altimeter measures altitude above mean sea level using static air pressure and is essential for safe terrain clearance.
39. What is the main difference between fixed-wing aircraft and helicopters?
Fixed-wing aircraft create lift with stationary wings and normally require a runway; helicopters use rotating blades (rotors) to produce lift and can take off and land vertically.
40. What does UAV stand for in modern aviation?
UAV means Unmanned Aerial Vehicle, commonly called a drone, which flies without a pilot on board.
41. Why is weight and balance important before a flight?
Correct weight and balance keeps the aircraft stable and controllable; if the centre of gravity is out of limits the aircraft can be difficult or impossible to fly safely.
