AOA DISAGREE Addon Badge (compatible with SAO standard)

A possibly authorized fix for the Boeing 737 MAX missing indicator option. Ours works!

Too soon?


For more information. see https://dc28.whiskeypirates.com/

This is the new DC28 v2 variant. For the original DC27 AOA, see here. For a kit version, see here.

  • We've gone digital - powered by WP CHIP advanced AOA logic!
    • Still more reliable than Boeing equipment as shipped
  • We've gone to 11 on the LEDs - one more than the previous model
  • Configurable display programs and speeds with rear-mounted variable resistors
    • Flashing your warnings in style
  • Badge comes fully assembled

There is an option for a retention lanyard. This helps prevent the addon from becoming lost by allowing you to clip the addon to something.

If you plan to use this addon on a badge, select the option.

If you plan to put this addon somewhere stationary, you may not want the lanyard as it could visibly interfere.


Includes one (1) AOA DISAGREE addon badge.


Please, maximum three per order unless prior arrangements have been made.
