Overview

Note: Compass deviation card is included.

The Precision Vertical Card Compass for todays aircraft. It is a dry compass, designed to replace the float/liquid type compass -- no more leaking fluid or backward azimuth readings. It uses eddy current damping and as such has no overshoot. 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. Fully TSOd. 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: A mount is required for installation with these unit and is not included. Click here to see mounts webpage.

Pretty simple install on the Cherokee I own...I like the vertical card style over the whiskey. The whiskey makes me feel like Iâm drinking and I need to think backwards. So far the vertical has proven to work well and has been very accurate. Setup took about 15 mins at an avionics shop that did the compass swing for me. Hopefully I have no issues with this compass down the road!

Such an improvement over the old whiskey compass. It is now actually a useful piece of equipment in the plane. In the 2 years I owned my plane, I had rarely ever looked at the ball compass, I use this all the time now for quick reference. Easy 10 minute install and alignment.

Q&A

Q: Can this vertical card compass operate on a tail dragger dash board as the aircraft is not level due to tilt?

Yes, this product is tested with tail dragger tilt in mind from the manufacture and we have had no issues or returns because of it.

Q: Can this compass be mounted in the instrument panel?

It can be, but it is not recommended due to the potential interference from other electrical units in the panel. If interference is detected, Mu-Metal (11-04483), can be used to shield the compass.

Q: My wet compass is 2-1/4" panel mount. If I replaced it with this compass in the panel it appears the green and yellow adjustment screws would be inaccessible. Is that a problem?

This compass is not intented to be mount to the panel and is a bracket mounted compass.

Q: If I insist on panel mounting, what size hole does the PAI 700 fit in?

It will fit a 2-1/4" size hole.

Q: Do you have a correction chart for this compass?

We sell generic compass deviation cards part number 10-01659.

Q: Does a Precision Vertical Card Compass require a power wire (not including one for the light)?

Power only needs to be attaching to light the gauge no power is needed for operation.

Q: Does the light bar come standard with the compass or is it an additional purchase?

You will need to select the voltage version first but yes they all come with internal lighting.

Q: Where does the deviation card mount for the Precision Vertical Card Compass PAI-700?

You may purchase a compass deviation card such as part# 10-01659 and mount it somewhere near the compass.

Q: If I buy the Precision Vertical Card Compass PAI-700 compass for the Northern hemisphere and fly to the Southern hemisphere will the the compass work correctly?

You would encounter errors. In order for a compass to work as intended, you need to fly in the hemisphere the compass was designed for.

Q: Does the Precision PAI-700 vertical card compass require a STC when installed in a certified aircraft?

The PAI-700 is TSO'd for use in certified aircraft. There is no STC available, a logbook entry is all that is required.
