6.5 PROMULGATION
6.5.1 If safeguarding of early turns is not provided a note must be added on the profile view of the approach chart:
“No turn before MAPt”.
6.5.2 The OCA/H for the nominal 2.5 per cent must always be published on the instrument approach chart. If
additional gradients are specified in the construction of the missed approach procedure, they and their associated
OCA/H values must be published as alternative options.
Table I-4-6-1. Values for Z (Earliest and latest MAPt for MAPt
determined by distance from the FAF)
Aircraft category Distance from nominal MAPt to earliest and latest MAPt
Category A max {2463; 0.3897D + 1086}
Category B max {2463; 0.2984D + 1408}
Category C max {2463; 0.1907D + 1787}
Category D max {2463; 0.1562D + 1908}
Where D = distance from nominal FAF to nominal MAPt (km). The values in the table are
SI units (meters).
Table I-4-6-2. Computation of transitional distance
Aircraft category Transitional distance (X)
Category A max {0.0875D + 2591; 0.3954D + 1604}
Category B max {0.0681D + 3352; 0.3246D +1653}
Category C max {0.0567D + 3794; 0.2328D + 1945}
Category D max {0.0495D + 4153; 0.2055D + 2073}
Where D = distance from nominal FAF to nominal MAPt (km). The values in
the table are in SI units (meters).
