Re: Embraer releases first pictures of its new turboprop

Pratt already has an engine capable of powering this, the PW150 (Q400 engine - 5071 SHP max) although I'm thinking Embraer would want something newer and more fuel efficient. One disadvantage of the low wing is adequate ground clearance for the prop so most likely a 6 or 8 blade will be used. I'll b...

The masks in the cockpit are "quick donning" so the pilots can pick them up and put them on at any time for any reason, not just de pressurization. Smoke or other toxic vapors in the cockpit would also require them to put the masks on. The cockpit masks do not drop from anywhere, and they ...
