Because an ILS is so challenging?

GPS devices are almost all solid-state... they care little about shock and perform fine in temperature extremes. Even my hand held Garmin is rated for 6g's and temps from 5-158F and that thing was only $200 ish.
The military seems to have this real aversion to utilizing GPS to the utmost of it's abilities.
That's great until China starts acting up and we turn the encryption back on.
No bucks, no Buck Rogers. I mean that's really what it comes down to...NavAir has to have the money to pay for it.
They have to invest in a certified GPS system in order to shoot approaches. And as Brett is saying, who the hell cares if you can shoot a GPS approach? It's still non-precision and it's not like you're going to use it around the boat.
I agree it's a great tool, and "should" be in every aircraft, but as those who've flown in the T-34 and to a lesser degree, the -57, you can see how much a kluge it turns out to be when you put new (cheap...it's the govt) gear in old equipment (NACWS, anyone?).
Must I do everything for you?just because you're not the one who makes the needles center![]()
And when the EU gets Galileo up and running, that won't matter to anyone.
Squeeze, I don't know about Galileo. What's the timeframe?
NACWS was crap before they changed the ATC freqs. Mafesto can probably tell us more about TCAS, but it's my undertanding that TCAS is far more accurate than NACWS is. More often than not, you'll get a NACWS hit after the traffic has gone by. It's something, and I'll give it that, but again, if more money had been spent, something better could have been used.
And what about the aircraft that will be flown until 2015+ (I'm looking at you HS/HSL)? Can it be overcome, sure. but those are examples of old airframes w/ only Tacan, and no real way to integrate GPS.
(Disclaimer: not aimed at you, but at the bean-counters running the government)
TCAS would be cool to have. Crap, I've heard of Cessna's with them.
The a$$-old T-39 got TCAS plugged into it too... worked a lot nicer than NACWS...
Uh-Oh ... I guess my secret and I are both outed .... my first IFR approach into Peking (or Beijing, if you prefer) in the 747 was an ADF approach to minimums. That's all the Gooks of Hazard had available at the time -- no BINGO and no business "deals" with the "white devils" for better equipment at that point in time .....why is it that anytime someone brings up IFR stuff, somebody has to point out how hard it is with an NDB?
NEWSFLASH: If you're flying IFR with only an NDB, you're a fvcking moron.
