How many primary types of ejections are there?

The correct answer is that there are three primary types of ejections. Ejection seats are critical for pilot safety, particularly in military aviation, where quick and effective egress from an aircraft can be a matter of life and death. The three primary types of ejection are:

1. Combined Mode: This mode allows pilots to eject at high speeds and low altitudes. It combines elements of both the automatic and manual ejection systems, enabling the seat to function effectively across a broader range of scenarios.

2. Rocket Mode: In this mode, the ejection seat relies on a rocket to propel the pilot away from the aircraft. This is particularly useful under circumstances requiring rapid ascent to avoid being entangled in the aircraft structure after ejection.

3. Manual Mode: With this mode, the pilot manually pulls the ejection handle to initiate ejection. This option is often deployed when automated systems may not be the best choice due to the specific altitude and speed conditions at the time of ejection.

These three modes highlight the versatility and adaptability required for emergency situations involving ejection, ensuring pilot safety across diverse operational contexts.
