Terrain Safe;
The current version of the LTCC MATS 2 doesn't say that SS tower will validate/verify Mode A or C and does say that CLN, DVR and LYD departures need to be identified by LTCC so you're right; it does need updating

The current version of the LTCC MATS 2 states that for departures from airfields with an Auto-DM capability it is not necessary to get aircraft to squawk ident to initiate flat tracking (nothwithstanding the need to get some of them to squawk ident for identification purposes.) I wonder if the incidents that you refer to relate to departures from an LTMA airfield which has auto-dm and no requirement for LTCC bods to ident?
