A320 Supplementary Procedure Question : ENG START WITH AIR START UNIT
Deal All
Kindly help me with this query
Question:
1. In the A320 Engine Start with Air Start Unit supplementary procedure, why does the procedure not require disconnecting external power after starting Engine 1 first, whereas if starting Engine 2 first, the procedure specifically instructs to disconnect external power?
2. What does solid circle and solid triangle mean in the supplementary procedure, I am not finding any reference to these symbols in the FCOM , kindly help me with a reference for these symbols
Thank you for taking time to answer
