mander or lead aircraft should emergen-
cy-start his TOD clock. Lead aircraft
would then transfer TOD to other aircraft
in flight. Aircraft using this method will

TOD signal in the AF mode. A valid TOD
signal must be transferred to all aircraft
that have invalid TOD time before effec-
tive AJ communications can be
achieved.
