What is the minimum temperature TO/LND?

• A. -60°C
• B. -50°C
• C. -40°C
• D. -30°C

Answer: (C)

The temperature used for TO/LND is limited by what the aircraft is certified to handle. The coldest ambient temperature at which takeoff or landing is approved for the ERJ 175 is -40°C. This means that if the air temperature is -40°C or warmer, TO/LND is allowed and the published performance data apply. If the temperature drops below that (-50°C, -60°C, etc.), TO/LND is not permitted because the certification and system limits can no longer be guaranteed to function safely. The other options represent colder temperatures that exceed the certification limit, while -30°C is warmer than the minimum and would still be permissible, but it isn’t the minimum.
