However, the rule book (TW5 8.4) states:
"If the DSD becomes defective at the same time as an AWS, TPWS or ERTMS failure, you must apply the conditions for that failure."
The conditions for the failure of both AWS and TPWS with a competent person provided are linespeed (See TW5 sections 4.5 AWS and 24.5 TPWS).
