A330 clock check during cockpit prep
 

Hi all,

In the A330 FCOM, during cockpit preparation procedure, the Clock has to be checked and set as necessary. But there is a note underneath stating "If the clock is readjusted for a value above ten days, maintenance must perform a Wing Tip Brake engagement test".

What does the clock setting have to do with WTB test? How are these two related?

Thank you for the links

Just try it in flight, once; advance the date more than 10 days and see the result... (don't!) :\

The WTB does a self test every ten days using that clock...
