In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

No, the Collins radar transceivers are not compatible with the KMD-850 Multi Function Display.
Yes, with the addition of the Avtech Digital Switching Unit (DSU) P/N 6001-1-1. List price for this unit is approximately $12000.
Weather radar transceivers use a magnetron which is basically a cathode emission device. The magnetron is subject to deteriorization due to aging. Therefore, it is recommended to perform some type of periodic maintenance to detect and correct the effects of aging. This reduces the chance of an in-service failure.

An annual, routine test of the following parameters should made:

- Power output
- Transmitter frequency
- AFC voltage
- Sensitivity (MDS)

Ideally, the test should take place between December and March prior to the peak thunderstorm season.
