The F-86F Sabre was equipped with either a type A-1CM or a type a-4 automatic lead and ballistic computing sight. This was located above and forward of the instrument panel shroud. In this case we are talking about the A-4 type sight selector, and these where used on the F-86f-10 and later airplanes.

In the lower arc of the unit u can find the sight function function selector lever. It can be set at either BOMB GUN or ROCKET. To ajust the sight system for the desired operation. When the selector lever is moved to BOMB, the sight reticle image is depressed to approwimate the bomb trajectory. Moving the lever to ROCKET permits permits subsiquent operation of the rocket setting lever to ajust the sight rectile image for the type of rocket to be fired. The selector lever will automatically return to Gun position, if set at either BOMB or Rocket, when the radar target selector button on the stick grip is depressed.

On the left side of the instrument you can find the target speed switch. This is used during gunnery missions to control lead angle data in accordance with speed ratio between the attacking airplane and its target. When the speed of the attacking airplane is greater than that of the target, tha target speed switch is set at IO. The switch is moved to HI when the speeds of the attacking airplane and the target are approximatley the same. The TR position is used when firing on a drogue or other training targets at low speeds.

It olso incorporates a rocket depression angle selector on the upper arc of the unit, with a scale calibrated in mils, for sight reticle image depression. There are no specific rocket settings. Movement of the rocket depression angle selector lever depresses the sight reticle image in increasing amounts through the full range of the mil scale, according to the position chosen. The nominal rocket depression angle selector lever setting for the 5-inch HVAR at a normal dive angle (0 to 40 degrees) is 17 mils. The pilot should determine, through test-firing runs, the settings for various dive angles most suitable to his own technique. The data thus obtained should be set on the mil scale with variable index markers so provided. the index markers, numberd from 1 through 4, are for reference only and have no function in the sight system. When pulled out, a pull tab near the 50-mil marker on the periphery of the selector unit face unlocks the index markers for adjustment.
