AN/ALE-40 Programmer

AN/ALE-40 Panel

The panel features 6 knobs to control chaff and flare programs, as well as two lamps and a switch to activate flares on its base.

Chaffs can be programmed to be released in Salvos and Bursts. A Salvo consists of multiple bursts, while a burst will release multiple chaffs.

Chaff Burst

The count knob (4) selects the quantity of chaffs released per burst; values of 1, 2, 3, 4, 6, or 8 from left to right.

The interval knob (1) selects the time interval of .1, .2, .3, or .4 seconds between each chaff released in that burst.

Chaff Salvo

The count knob (5) selects how many bursts the salvo consists of, values of 1, 2, 4, 8, or C (Continuous).

In the Continuous setting, the program is repeated as long as the dispense button is held down.

The interval knob (2) selects the time interval between each burst. Values of 1, 2, 3, 4, 5, 8, or a R (Random) number of seconds.

Flare Burst

The count knob (6) selects the quantity of flares released per burst. Values of 1, 2, 4, 8, or C (Continuous).

Continuous will repeat the program as long as the dispense button is held down.

The interval knob (3) selects time interval between each flare released. Values of 3, 4, 6, 8, 10 number of seconds.

Flares Select Switch

The flares select switch (9) controls which countermeasure will be released when the pilot presses the Dispense Button.

In the NORMAL setting, countermeasure are released according to what the WSO setup on their panel.

Aural Tone Control

Aural Tone Control

Knob to control the volume for weapon tones, such as the Sidewinder seeker head.

Anti-G Suit Control Valve


The anti-G system delivers low-pressure auxiliary air to the anti-G suits, with air passing through the anti-G suit control valve before reaching the suit. The suit remains deflated up to approximately 1.5 G, and as G forces reach or exceed this level, air flows into the suit proportionally. The suit stays inflated in relation to constant G forces and begins to deflate as G forces decrease.

A manual inflation button in the anti-G suit control valve enables the crew to manually inflate the suit for system checks or fatigue relief. A pressure relief valve within the system activates at approximately 11 psi, serving as a safety backup in case of malfunction. The system operates automatically whenever an engine is running, ensuring continuous support for the wearer during varying G-force conditions.
