The burning question is: when do you initiate the turn on a missed approach if there is no MAPt?
The answer is in ICAO DOC 8168 vol1
6.1.4 It is expected that the pilot will fly the missed approach procedure as published. If a missed approach is initiated before arriving at the missed approach point (MAPt), the pilot will normally proceed to the MAPt (or to the middle marker fix or specified DME distance for precision approach procedures) and then follow the missed approach procedure in order to remain within the protected airspace. Note 1.— This does not preclude flying over the MAPt at an altitude/height greater than that required by the procedure. Note 2.— In the case of a missed approach with a turn at an altitude/height, when an operational need exists, an additional protection is provided for the safeguarding of early turns. When it is not possible, a note is published on the profile view of the approach chart to specify that turns must not commence before the MAPt (or before an equivalent point in the case of a precision approach). 6.1.5 The MAPt in a procedure may be defined by: a) the point of intersection of an electronic glide path with the applicable DA/H in APV or precision approaches; or b) a navigation facility, a fix, or a specified distance from the final approach fix (FAF) in non-precision approaches.
