Approach and Landing Flashcards
Aircraft divided into … categories depending on their target threshold speed (Vat or Vref)
Vat is either
Vs0 x …
or
Vs1g x …
5
1.3 Vs0
or
1.23 Vs1g
an instrument approach can be commenced regardless of RVR or visiblity but cannot be continued below …ft above the aerodrome if the RVR or visibility is below the approach minima
However, if after passing that height, the reported RVR or vis falls below the minimum the approach may be continued to …
1000 ft
DA/H or MDA/H
If DA/H or MDA/H is above … above the aerodrome the approach cannot be continued into the final approach segment if the RVR is below minima
1000ft
Where RVR is not available for landing equivalent values can be found by converting the prevailing met vis to converted met vis - Converted Met Visibility
may not be used to assess … and it cannot be used for calculating required RVR minimum less than …m, or when the RVR is actually reported
take-off RVR
800
Min RVR for a visual approach =
800m
NPA MDA/H is never lower than … and RVR/CMV not less than …m (unless accepted by the authority)
250ft
750m
MDH for LOC with or without DME =
250 ft
MDH for GNSS (LNAV) =
250ft
MDH for SRA terminating at 0.5nm =
250ft
MDH for VOR/DME =
250 ft
MDH for VOR =
300 ft
MDH for SRA terminating at 1nm =
350 ft
MDH for NDB/DME =
300 ft
MDH for SRA terminating at 2nm =
350 ft
MDH for NDB =
350 ft
