AFSB Tip by Retd. Air Force Officer: The board doesn’t expect you to know everything about flying. However, a little knowledge is always advantageous. If you don’t know anything, calmly say, “I don’t know, sir.”

## 🚁 AFSB Interview Questions

These are some The board will be more impressed if you show enthusiasm for learning. Ask the board to explain any questions you don’t understand.

What is Bernoulli’s principle, and what is an example of it?

Ans. According to the Bernoulli principle, A1V1 = A2V2, an increase in a fluid’s speed happens simultaneously with a decrease in its pressure or potential energy. The venture tube is an example.

On what principle does an aircraft fly?

Ans. Aerodynamics, also known as Bernoulli’s principle, governs how aeroplanes fly. While the engines provide thrust, the pressure differential over and below the wings lifts the craft.

Could you please explain to me what buoyancy is and how it relates to aircraft?

Ans. The force acting on an object that is partially or fully submerged in a fluid is known as buoyancy. A plane needs to move down a mass of air each second equal to its own mass in order to fly. This situation also fits within the buoyancy principle.

What is the meaning of streamline shape? What is the importance of this?

Ans. A streamlined shape lowers the friction drag between a fluid, and an object moving through that fluid. This shape is important because it reduces drag to a very high extent.

What is the difference between knots, nautical miles, and mach?

Ans. A nautical mile per hour is measured iA mile equals 1.6 km/h, and a nautical mile is 1.8 km/h. .6 km/h. Mach is the ratio of the speed of the object to the speed of sound. The speed of the object to the sound speed is expressed as a ratio known as Mach.

Which aircraft is the largest in the Indian Air Force?

Ans. The Boeing C-17 Globemaster is the largest aircraft in the IAF inventory. Before the induction of the C-17, the largest aircraft tag was given to the Illyushin-76, also known as Gajraj.

Can you tell me the three sub-branches into which the flying branch is divided?

Ans. Sir, the Air Force has 3 sub-branches of flying: Helicopters, Fighters, and Transport Fleets.

Please tell me the names of any five IAF transport aircraft.

Ans. Sir, a few of the transport aircraft are the C-130J Super Hercules, C-17 Globemaster, Il-76 (Gajraj), AN-32, and Refueler Il-78.

Please provide the names of five fighter aircraft of the Indian Air Force.

Ans. Sir, a few of the fighter aircraft are the Tejas, Su-30, Mig-29, Mig-21 Bison, and Jaguar.

Name three helicopters of the Indian Air Force.

Ans. Sir, a few of the helicopters are the Mi-17, Mi-35, and ALH Dhruv.

What is the most recent aircraft inducted into the Indian Air Force?

Ans. Sir, most recently, the Air Force has inducted the CASA C-295 as a replacement for AVRO aircraft. Before that, Tejas was inducted into the Air Force. It’s an indigenously made light combat aircraft with the nickname ‘The Flying Daggers’.

What aircraft have been added to the IAF’s vintage fleet?

Ans. Dakota, aka Parashuram, has been added to the IAF’s vintage fleet. Air Force has also been showcasing it in their 8th Oct flypasts for the last few years.

In what capacity do aircraft play a role in the Indian Air Force?

Ans. An aircraft is a vital component of any air force. Providing air superiority to any country’s military is one of their primary functions. The aircraft of the Indian Air Force serve the same purpose – to defend the country’s borders and fight in wars.

How does the Air Force utilize its aircraft when it is not engaged in combat?

Ans. When not involved in hostilities, the Air Force participates in humanitarian and disaster relief operations, participates in joint training exercises with other militaries, and ultimately prepares for war.

Where do aircraft fly in the atmosphere?

Ans. A plane can fly comfortably in the stratosphere. There is constant movement of the air below this level, resulting in turbulence.

Could you tell me the names of all the IAF trainer aircraft?

Ans. Among the trainer aircraft that the IAF operates are Pilatus PC-7s, Hawk HJTs, Kirans, Dorniers, etc.

Which components make up an aircraft, from the nose to the tail?

Ans. It consists of a cockpit, fuselage, wings, undercarriage, stabilisers, aileron, elevators, rudders, etc.

Which five instruments can you find in a microlight?

Ans. There is an airspeed indicator, an altimeter, a slip/slip indicator, a compass, and a fuel indicator.

A plane consists of three basic motions. What are these motions?

Ans. An aircraft has three basic motions: pitching (as controlled by the elevators), rolling (as controlled by the ailerons) and yawing (as controlled by the rudder).

Fly-by-wire systems are used in aircraft. What are they?

Ans. A fly-by-wire system replaces an aircraft’s manual flight controls with an electronic interface. Electronic signals are generated by the movement of flight controls. Essentially, it is a digital version of a mechanical flight control system.
