Early-model Cessnas originally utilize older-style, wire- wound transmitters. These transmitters are located in the wing, where they are exposed to humidity and extreme temperatures. After many years in such harsh evironments, these transmitters become worn and corroded, causing them to fail or become intermittent. Owners have been plagued with high maintenance costs, difficulties obtaining replacement parts, as there are compatibility issues the various trasmitters and the gauges. The Visual Instruments Flap Indicator system provides a means for owners of these older aircraft to upgrade their troublesome indicators to a modern, more reliable design. The system includes a new transmitter, a modern digital display, and all parts necessary to perform the upgrade.

The new display incorporates a color LED bar graph. The appearance is similar to flap indications shown on modern glass cockpits. Positions of more than 10 flap are indicated in a different color. This allows for easy identification during an emergency procedure such as a balked landing (go-around).

The LEDs are very viewable from a wide angle. This is particularly useful since the indicator on many Cessna models is located on the right side of the panel. The display automatically adjusts to the ambient light for IFR or night operation. The Flap Indicator system includes all necessary parts and typically takes a mechanic approximately 2 hours to install. 2 year factory warranty. STCd for installation on early model Cessna 172s, 182s, 205s, 206s, & 210s.

WARNING: Cancer and Reproductive Harm -


Cant say enough positive for the Digital Indicator team, mine is for a 210A, which is different, and requires a slight mod to the flap arm. They have been superhelpful in getting it installed and working.

After trying to find a used sender that would replace the one in the wing and finding the Cessna price to be in the $1200 range. The fact that the aircraft could have any one of the three different types of senders used over the years I decided to splurge. This gauge is very readable with its color coded ranges. The sender is not just an old auto type fuel gauge sender and it has a much better, more positive connection (not that little wire connected to the pulley in the wing). Had it installed in about one hour as the old gauge and sender were already out.

Fast shipment, well packaged, easy to follow instructions. Everything was included for log book documentation. I`m always pleased with my purchases from Aircraft Spruce. Excellent customer service.

Good design, simple hardware, easy installation. Much better than the original hardware.

Great idea, bad execution. The Flap Indicator signal circuit has a electronic ground loop. The aircraft has two different ground points in the circuit. With the Visual Instruments gauge, you get static when the flaps are in transit and more LEDs light up. Result is you cant tell where your flaps are at until you move the switch to neutral. Now in the 1960s when the OEM circuit was designed, this was not a problem. However LEDs are highly effected by interference. The solution is simple single point grounding. Did they not test this in a real airplane??? Fail!!

The individual light bars started to fail. First the 3rd (last green) then the 4th (first yellow) I called the company and was told that there is no fix for this and I need a new unit. I purchased my plane with this unit and had no problems for the first 3 years. I am not sure what to do but feel that it’s a shame to replace the complete unit for a few indicator lights

I love the idea - update to the digital age! Night visibility! Unfortunately, the unlit lights somehow pick up interference from the flap motor and light up while the flaps are in transit. Can't tell where your flaps are at until you move the switch to neutral. Manufacturer will not respond to emails or phone messages asking for help. For this price, shame on them!
