Answer» Correct answer is (a) To find crew and PAYLOAD WEIGHT so initial W0 can be guess Easiest explanation: Take-off gross weight is determined in stepwise manner. It is an iterative process in which we FIRST find weight of crew, passenger, PAYLOADS etc. After which next step is to guess gross weight based on crew and payload weight.
