ATR72-500 RNP

[Capt. Glenn Quagmire]

I flew ATRs way way back. Could someone tell me what is the ATR72-500 certified to with regards to RNP. I believe that the-600 can do 0.3 RNP but am keen to hear about the -500.

RNP for ATR

For the ATR 42-500 we used RNP 5

In other words, BRNAV. Isnīt it?

Hi

HT1000 is capable of RNP 5, RNP-1, LNAV with advisory VNAV not baro VNAV due to "complications" with EASA.

ht1000 gnss is capable of
enroute = Rnp2
terminal = Rnp1
approach = Rnp0.3

it switches automatically to terminal from enroute when 30 miles short n then just short of FAF it switches to approach RNP.

Thanks to all who replied. Much appreciated.

So therefore is the -500 approved to fly GNSS approaches but not RNP AR is what I gather.

I guess the sales will come to an end soon enough and only the -600 will be offered anyway.

According to the manufacturers specs..both ATR 72-500 and ATR 72-600 are certified at 0.3 RNP.

If I were stuck flying an ATR, RNP would be the least of my worries.

To my knowledge, ATR ended -500 production at the end of 2012. Only -600's are offered now.

500 can only perform LNAV RNP APCH.

The 600 is SBAS capable with different THALES FMS/GNSS units allowing LNAV, LNAV/VNAV, LPV and LP RNP APCH.

Not sure but I think the 600 can do RNP AR APCH. But no CAT III at the moment and no GLS.

Anyone know anymore on the 600?

It has a very strong resemblance to actual work, something I am very averse to. I became a pilot specifically because I have no desire to work for a living.
