(a) By day, a series of projectiles discharged at intervals of 10 seconds, each showing on bursting black or white smoke;

(b) By night, a series of projectiles discharged at intervals of 10 seconds, showing on bursting white lights or stars, or an intermittent white luminous beam directed at the aircraft:

Provided that, when the authority who desires to give the order for the change of course referred to in this paragraph is able to establish radioelectric communication with the aircraft, this order may be given by using the means of communication established.'

"29. An aircraft which overtakes another aircraft shall keep out of the way of the overtaken aircraft by altering its own course to the right.

If an aircraft approaches another aircraft from the rear, following a course forming an angle of less than 70° with the plane of symmetry of the latter, that is to say, is in such a position with reference to the other aircraft that at night it would be unable to see either of that aircraft's side lights, the aircraft approaching the other shall consider itself to be an overtaking aircraft, and no subsequent alteration of the relative position of the two aircraft shall make the aircraft which approaches the other a crossing aircraft within the meaning of these rules, or relieve it of the duty of keeping clear of the course of the overtaken aircraft until it is entirely past and clear.

As by day an aircraft which approaches another aircraft from the rear cannot always know with certainty whether it comes within the case provided for in the last preceding sub- paragraph, it should, if in doubt, assume that it is overtaking the other aircraft and alter its own course to the right.'
