Issues with CAT I aircraft at TIST

[Fearless]

Hi Team,

Current controlling at TIST but I seem to have problems with CAT I aircraft Taxiing to either the terminal, apron or gateway. They remain positioned at the entrance from the taxi way and whilst they acknowledge the 'taxi to' command they stop moving.  Then when I issue the 'continue taxi' command, no response is received and they remain at that position.

Also I've had instances whereby the aircraft acknowledged the 'negative' response when given the 'continue taxi' command when they are stopped before crossing of the runway to their line up.. The only way I could get the aircraft to continue to taxi was by giving the command 'lineup and wait'.

Any advise would be greatly appreciated.

Happy Holidays.
