More humble than you would understand
What's the Comm/Nav package on the Navy T-6s? Is it off-the-shelf, like a Garmin-based suite, or a military system?
Does it have DOD approaches or just Jeppesen?I never could find the trade name for it in the NATOPS manual, like how the TH-57 manual says this unit is a King KNS-81, etc.
I think the FMS uses the Jeppesen Americas database but there are some high altitude approaches missing in there. The FMS does SIDS, STARS, approaches, and enroute, wind vector, TCAS, and a few other things like a big boy avionics suite. There are a few big things that it doesn't do- fuel computations and vertical nav come to mind, but overall it's a very good system for its intended purpose.
The LNAV-only non-WAAS GPS is kinda outdated and I doubt we actually saved any money with that choice. It's the GPS receiver, not the FMS per se. The FMS wouldn't know or care if you fly to LNAV-VNAV or LPV mins instead and it doesn't know what you set in the altitude bug.
Strangely, the avionics suite doesn't include display outside air temperature or TAT, which is a couple of pretty dumbass things to omit in an airplane that is approved for some icing. The avionics suite has a TAT sensor and it knows what that and SAT is at all times, and it does display TAS and Mach. But instead of just having it displayed, you have to borrow the T2 temperature from the engine display and then fumble around with a temperature correction chart in the pocket checklist. At least the page number is easy to remember, it's page "P-8." (I would have called it page "HSL" just as easily.)
Thank you for giving me an opening for another one of my retired guy rants.
It's got mil and civil approaches.Does it have DOD approaches or just Jeppesen?
