Using the BT-3 Sight with the B17 & Picture of BT-9 Sight in the A21A-3
How the CCRP functions in a attack run:
Function during Dive Bombing
Before the attack, the pilot sets the attack type (level or dive), weapon type, estimated air pressure at the target, wind speed and direction, and the aircraft’s estimated gross weight. During the approach, the gyros are levelled, and the system confirms when the gyros are free. The release button is armed. Using the reflex sight, the pilot aligns the aircraft with the target in level flight at a shallow dive angle, typically between 5-30 degrees. The system confirms that the aircraft is within the sight’s operational range. When the release position is achieved, the release button is pressed, initiating a gentle pull-up. The release button is held down until the pull-up is completed. The sight automatically calculates the correct release timing for the bombs.
Function during Rocket Firing
J21RB Shooting rockets Guided by a SAAB BT-9
Rocket firing is conducted during a dive towards the target. The pilot only needs to stay roughly within the prescribed firing range for each type of rocket. The sight automatically accounts for the aircraft’s speed and dive angle.
