Keep your Brainteaser Decoder Ring™ handy and refer to this partial NOTAM:

Ailerona IA [IA66]: February NOTAM #45 Aerodrome airport WDI for runway 23 light OUT of SERVICE

The Runway 23 WDI is OUT of SERVICE. But you don't need to push the Ercoupe back into the hangar, because you know that WDI means:


Wind Direction Indicator


Weather Detection Indicator


WAAS Deflection Index


Wabbits of Destructive Imagination
