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.
So far I love it. But when calibrating the compass card, I noticed very small movements, like under five degrees, the card doesnt move unless there is movement, like engine vibration. (Not a problem when the engine is running), but if your holding the compass very still and turn it, nothing happens in very small movements, like under five degrees, tap it on the side with your finger gently and it moves and points correctly. A none issue in a running plane Other than that, I really like it, I was so tired of struggling to see my compass numbers, this is super easy to see, and turns in the same direction of my directional gyro.
Sticky during turns. Freezes while turning then suddenly catches up after leveling off. I gave it 2 stars because it looks good and is easy to read but forget timed compass turns during IFR training. Wish I kept my whiskey compass.
Purchased and had installed by avionics vendor. Unit didnt last a year and froze up. Was nice while it lasted but short service life a major disappointment. Back to the reliable whiskey compass.
Works fine, easy install
Easy mount using the same mount as the whiskey compass. Wired for illumination. (Consider using quick disconnect fittings) internal magnets are much stronger than a whiskeycompass, so your plane may require shielding and/or balancing balls compensators. Easy to read.
Looks good, hopefully works good, hopefully last long time.
Compass worked fine for the first 2-3 weeks after installation, then it froze in the same heading. I couldnt adjust it and it stayed frozen after I removed it from the airplane. The vendor, Precision Aviation Inc., claimed there was nothing wrong with it and wanted a $165 fee to inspect it. The compass was under warranty. I protested and Aircraft Spruce sent me a replacement but the process left me without a compass for a month.
Compass failed in less than one week after install. Stuck at North. Doesnt move off of North no matter what direction the airplane is pointed. Returning for refund.
No Surprises. Very easy installation. Well worth the money.
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.
