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.

Yes, FreeFlight and Jeppesen have developed a "4MB Upgrade Program" for the Approach & Approach Plus systems.

The upgrade will entail a minor hardware modification, software upgrade, and a higher capacity 4MB data card. With this upgrade, pilots will have continued access to the Jeppesen NavData©.

Approach and Approach Plus model upgrades must be completed by June 4, 2009 to be able to continue to receive Jeppesen NavData© services.

This upgrade is applicable to all FreeFlight Systems TSO-approved Approach and Approach Plus GPS Navigation Management Systems (including I/O models) and equivalent legacy equipment with the Trimble name. Including: TNL 2000 Approach & Approach Plus; FreeFlight / Trimble 2101 & 2101 I/O Approach & Approach Plus.
Newer FreeFlight 2101 I/O Approach Plus models ending in -32, -33 or -42, with MOD 14 marked out, have already received the hardware modification and may be updated in the field.

The "4MB Upgrade Program" enables customers to contact their dealer directly to arrange for your systems to be returned to the factory for the necessary hardware, software upgrades & new data card. Factory pricing will vary depending on upgrade requirements. Contact Southeast Aerospace for more information on your upgrade options.

To provide further information, FreeFlight has released Service information letters, SIL FFS02 & FFS03, as well as FAQs.

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 75% of the original exchange price. That is, it cannot cost SEA more than 75% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

Both dash numbers are Black, Non-NVG front panel units; however -02 has GPS CCA P/N 30212 and -32 has GPS CCA P/N 84588. Parts obsolesce required the change of the CCA card and to indicate that change, the part number was changed.

There is no difference in function of the two units.
Any unit with the Plus designation has a 12 channel GPS receiver. Any unit without the Plus designation has a 9 channel GPS receiver.
