Embraer 175 max temperate for takeoff?
 

Having a heatwave and wondering what the ambient air temperature on the ground can be for an Embraer 175 to takeoff? I assume under 40C/104F will be fine?

What carrier and what country and what specific location?

Different carriers equip and therefore apply for higher operating temperatures and different aviation regulators may permit that. Altitude also affects operating performance. Therefore heat at higher altitude becomes a greater problem.

AA recently obtained approval to operate (or have operated by its express contractors) some of its -175's operating out of airports such as PHX, at substantially higher temperatures than in the past.

That’s not the only factor used in making go / no go decisions.

Factors used include aircraft takeoff mass and balance; temperature; air density; wind; runway conditions (runway length, field altitude, runway surface, runway slope); flap setting and airframe contamination; available thrust. That means two Embraer 175s might have different takeoff limitations. Link.

All very interesting!

It was AA from PDX. Full passenger load plus two staff. Temperature didn't hit triple digits in the end. Even prop planes were still running that day, so don't think it was quite as hot as I had imagined! :)
