Which navigation instrument features a vertical card with an azimuth and a fixed miniature airplane to display heading?

Explanation:
Heading indication is provided by a vertical card compass, which uses a vertical compass card with azimuth marks and a fixed miniature airplane to show heading. The card rotates to display magnetic direction, while the tiny airplane stays stationary in front of the card; you read the heading where the airplane points to on the azimuth scale. This setup is specific to the vertical card compass and is not used by the vertical speed indicator (which shows climb or descent rate), VHF (communication), or a venturi tube (measures airspeed or pressure).
