Rotex Interview Questions and Answers

Icing and deicing of aircraft are important processes to prevent ice buildup on critical surfaces.

• Icing occurs when supercooled water droplets freeze on aircraft surfaces, affecting aerodynamics and increasing weight.

• Deicing involves removing ice from critical surfaces using deicing fluids or mechanical methods.

• Deicing fluids can be heated and applied to aircraft surfaces before takeoff to prevent ice buildup.

• Examples of deicing fluids include ethylene glycol and propylene gl...read more

Icing can add weight and disrupt airflow, while deicing removes ice to prevent aerodynamic issues.

• Icing can add weight to the aircraft, affecting its performance and fuel efficiency.

• Ice accumulation can disrupt airflow over the wings and control surfaces, leading to loss of lift and control.

• Deicing is necessary to remove ice buildup and prevent aerodynamic issues during flight.

• Deicing methods include using heated fluids, inflatable boots, or chemical treatments to remove ice ...read more

Pressure and temperature decrease with altitude in the atmosphere. Lapse rate is the rate at which temperature decreases with altitude.

• Pressure decreases with altitude due to the decreasing weight of air above.

• Temperature decreases with altitude at a rate of 6.5°C per kilometer in the troposphere.

• Lapse rate is the rate at which temperature decreases with altitude, usually around 6.5°C per kilometer in the troposphere.

• Lapse rate can be used to determine stability of the atmosp...read more

A six-pack instrument in an aircraft refers to the six primary flight instruments displayed in the cockpit.

• Includes airspeed indicator, attitude indicator, altimeter, turn coordinator, heading indicator, and vertical speed indicator

• These instruments provide essential information to the pilot for maintaining control and orientation in flight

• Used for navigation, altitude control, and monitoring aircraft performance

Thrust is generated by the propulsion system of an aircraft, with different engines having their own advantages and disadvantages.

• Thrust is generated by the propulsion system of an aircraft through the combustion of fuel and the expulsion of high-speed exhaust gases.

• Different types of engines, such as turbojet, turbofan, turboprop, and ramjet, have their own unique characteristics and performance capabilities.

• The choice of engine depends on factors like aircraft size, speed r...read more
