bombsight specialist Interview Questions and Answers

1. What is a bombsight and how does it work?

   • Answer: A bombsight is an optical or electronic device used to calculate the required aiming point for dropping bombs from an aircraft, accounting for factors like aircraft speed, altitude, wind speed and direction, and bomb ballistic characteristics. It essentially predicts where the bomb will land based on these inputs and guides the pilot to release the bomb at the optimal moment.

2. Describe the different types of bombsights used historically.

   • Answer: Historically, bombsights evolved from simple optical devices like the Norden bombsight (known for its precision) to more advanced computerized systems. Examples include the early bombsights relying on manual calculations, the Norden M-9, the AN/ASQ-18, and modern GPS-guided bombsights integrated with inertial navigation systems.

3. Explain the role of ballistic calculations in bombsight operation.

   • Answer: Ballistic calculations are crucial. They account for factors like gravity, air resistance (drag), and the bomb's trajectory to determine the release point necessary for the bomb to hit the target. These calculations need to be extremely accurate, especially at longer ranges.

4. How does wind affect bomb delivery accuracy, and how do bombsights compensate for it?

   • Answer: Wind significantly impacts accuracy, pushing the bomb off course. Bombsights compensate by incorporating wind speed and direction data (often obtained from weather reports or onboard sensors) into their calculations to adjust the aiming point accordingly.

5. What is the significance of the Norden bombsight in World War II?

   • Answer: The Norden bombsight was a highly sophisticated electromechanical bombsight used by the US during WWII, famed for its relatively high accuracy compared to other bombsights of the time. Its complexity and precision contributed significantly to Allied bombing campaigns.

6. What are the limitations of optical bombsights?

   • Answer: Optical bombsights are limited by visibility. Adverse weather conditions like clouds, fog, or darkness significantly reduce their effectiveness. They are also more susceptible to errors due to human factors in manual input and interpretation.

7. How do modern GPS-guided bombsights improve accuracy?

   • Answer: Modern GPS-guided bombsights use satellite signals to determine the aircraft's precise location and the target's coordinates. This significantly increases accuracy, reducing the need for complex ballistic calculations and eliminating errors due to poor visibility.

8. Describe the process of calibrating a bombsight.

   • Answer: Bombsight calibration involves adjusting the internal mechanisms or software to ensure accurate readings and calculations. This typically involves testing under controlled conditions, comparing the bombsight's predictions to actual bomb impacts, and making adjustments based on the discrepancies.

9. Explain the role of inertial navigation systems in modern bombsights.

   • Answer: Inertial navigation systems (INS) provide backup navigation data even when GPS signals are unavailable or disrupted. They measure the aircraft's acceleration and rotation to determine its position and orientation, aiding bombsight accuracy in challenging environments.
