PRECISION PAI-700 TSO'd...
The PAI-700 TSO'd Vertical Card Compass is manufactured exclusively by Precision Aviation, Inc. This non-liquid (dry) type compass is magnet driven thus it is subject to lead and lag, however, these tendencies are greatly reduced due to the absence of pendulosity. It is inherently stable due to the use of eddy current damping which is a natural phenomenon built into the basic design and as such has no overshoot. The PAI-700 has been designed to replace the float/liquid type compasses eliminating leaking fluid or backward azimuth readings. Available for Southern and Northern Hemisphere and different supply systems (5V, 14V and 28V). Precision Avionics Inc. also manufactures different compass brackets for overhead or glare shield mounting.
The Precision PAI-700 Vertical Card Compass consists of a 2" vertical rotating dial which is compared with a fixed miniature airplane (lubber line) to present the magnetic heading of the aircraft at all times. Heading information is more natural because the heading is read at the12 o'clock position and off the nose of the miniature aircraft. The compass card rotates and presents all quadrants in their true relation to line of flight. Requires no power (except for lighting) to operate. Installed in many current production aircraft & helicopters. Size: 2-7/8"H x 2-3/8"W x 2-1/8"D. Wt. 0.6 lb. After installing compass must be compensated using standard compensation procedures. Also used in sailplanes.
Note: Compass deviation card is included. A mount, sold separately, is required for installation with the unit.
