A typical modernization consists of controller equipment, electrical wiring and buttons, position indicators and direction arrows, hoist machines and motors (including door operators), and sometimes door hanger tracks.

I can move my controls But I don't know if the cannon is moving, I've lost all position indicators.

The position indicator was switched to maximum magnification but it revealed nothing.

Other modes include Plan position indicator (PPI) display, RHI displays, etc.

The wayside signals consist of point (switch/turnout) position indicators in proximity to switches and inter-station signalling placed at each station stop.

The linear trim position indicator runs immediately behind it a red pointer moving back and forward to markings numbered either side of a central zero.

At lower left are trim and flap position indicators twin oil pressure and temperature gauges and a dual-pointer brake and hydraulic pressure dial.

However, even when the ground floor button is marked with a letter, some digital position indicators may show 0 when the lift / elevator is on that floor.

The hydrophones may do more than act as position indicators.
