Hello. Thank you all for the response. Just want to share my understanding of the procedure as described to me by a A320 TRI and do let me know if it is correct
1. Starter assisted relight- If our flight parameters fall under these region during inflight relight scenario, (Light aircraft,descending at Green dot speed due to obstacles , basically obstacle strategy) the start sequence is limited by the starter engagement limitations i.e. if it does not start within 35, starter cooling required . But the limitations on FCOM is with regards to ground start, couldn't understand this part :-)
2. Windmill Quick relight- Governed by the N2 speed and T<20s (PW engines) ,if the engines are not started by within the time T<20s, the master needs to be turned off.?
3. Windmill Relight- Governed by N2 speed and 30s as per the QRH procedure
