What is the minimum engine start temperature for the Embraer 170/175?

The minimum engine start temperature for the Embraer 170/175 is indeed -30°C. This limitation is crucial for ensuring that the engine oil and fuel can adequately flow and provide necessary lubrication and combustion during the starting process. Starting an engine at a temperature lower than this specified limit may lead to issues such as fuel freezing or oil thickening, which can compromise engine performance and reliability. Additionally, it helps to avoid potential mechanical stress and failures that can occur when engines are operated outside of their safe temperature ranges. Understanding this limitation is vital for ensuring safe operations and maintaining the integrity of the aircraft's engine system.
