I teach pilots from all and every corner of the globe and have only Jepps (via JeppView) to use as reference material. The complexities of the situation mitigate against simple solutions but I need a simple solution if I am to succeed with the IFR part of any course.
If, when asked, the student replies that his organisation has no CDFA SOP then I will use the published DA plus 50 feet and fly it in the same way you fly an ILS with the application of GA power at DA+50 unless the required visual reference is available.
The briefing will include a simple explanation that:
a. Where an MDA is shown on the plate for a Non Precision Approach the approach can be flown in the 'old' way with a level off at MDA and a GA to be initiated at the MAP.
b. Where a DA is shown with no explanatory information the DA + 50 will be the rule.
c. Where there is an indication that use of the DA has been approved because the re-evaluation of obstacles in the context of a descent below DA during a GA then the DA may be used without the 50 feet increment.
d. Visibility parameters will need review when setting up the sim weather if a 'break-out is required for a revised DA plus a revised GA point will put the pilot flying in a position where the published vis minima will almost certainly be inadequate.
Would appreciate feedback on this approach to the problem.
