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.

This is my second PAI-700. I bought the first one in 2007 and transferred it progressively through 3 gyroplanes. It has always worked perfectly and is responsive enough to keep up with aggressive gyroplane maneuvering. In the last installation it was sitting in the open above the instrument coaming and last year was heavily rained on overnight (after the gyro was left out uncovered thinking it wouldnt rain). Humidity then fogged it up but it still worked. A month ago I ordered a new PAI-700 to replace the fogged one, intending to permanently retire it after a long working life. Within 3 days the new PAI-700 had arrived (to Australia). However, the old compass evidently decided to soldier on, because between the day I ordered the new one and was intending to put it in, the fogging in the old one cleared up. So, now Im keeping the new one as a spare! The only difference between the old and new one are different serial numbers and the dial on the older one is a bit faded compered to the brand new one.
I installed this, then went flying. Set my DG on the runway heading, and once in the air headed north. I made a small correction to zero the compass on north and did the same on east. All other headings were right on. No other adjustments necessary. I notice it takes a moment to settle on the any new heading. It didnt behave exactly like a DG in that respect, but to set your DG you world be right on.
I appreciate the professionalism and help from Aircraft Spruce.
Great product, easy to read, doesn’t bounce all over the place 👍 very happy with it.
Aircraft Spruce is the only aircraft parts company ( OUT OF THE FOUR IVE USED IN THE PAST 30 DAYS) that has gotten an order correct as ordered on the initial order input. The customer service remains outstanding : pleasant, knowledgeable and efficient. thank you
Pretty simple install on the Cherokee I own...I like the vertical card style over the whiskey. The whiskey makes me feel like I’m 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.
Not installed yet but looks fine. Well packaged.
Excellent product. The Grumman Airplane attaching bracket that I also purchased, worked perfectly and so easy to install.
Thank you for the great Customer Service. I called this order in right at 3pm, and it still got out the same day!! Plus the bracket was shipped from IL facility and the compass came from the GA facility! Awesome Customer Service!!!!

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.
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.
This compass is not intented to be mount to the panel and is a bracket mounted compass.
It will fit a 2-1/4" size hole.
We sell generic compass deviation cards part number 10-01659.
Power only needs to be attaching to light the gauge no power is needed for operation.
You will need to select the voltage version first but yes they all come with internal lighting.
You may purchase a compass deviation card such as part# 10-01659 and mount it somewhere near the compass.
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.
The PAI-700 is TSO'd for use in certified aircraft. There is no STC available, a logbook entry is all that is required.
