Eggsakly. Boeing and Airbus sell the "Full Monty" to 3rd world carriers, at full list price, subsidized by EX-IM or EURO financing at low rates. They all get full rated thrust, every option (down to rain removal fluid and brake fans on 320). We (UAL and other US carriers) dumb down our aircraft and negotiate for a lower price.
Sorry. GMAFB. I flew brand new Chinese 319's and 320's and brand new Vietnamese 321's. And we used sims in a couple of other countries, including Singapore for PC's. We got the dumbed down versions. The Singapore sims had "Disco smoke" systems to simulate (extremely well) smoke in the cockpit. Anybody at UAL or CAL ever get real smoke in the cockpit in a sim? No, I didn't think so.
3rd world carriers get the lot. We will dumb it down when it arrives to reduce "differences".
Rain removal fluid rocks. I can't believe how much better it is than wipers. Brake fans are an Airbus scam, except maybe for 321's. I have never flown 321's without them, so I will defer.
It is cheap and easy to disable or derate stuff we don't want. Not so much the other way.
