Operational Documentation, Charts and NOTAM Interpretation
The document set
Operational documentation includes the operations manual, the aircraft flight manual, performance data, mass and balance data, route and aerodrome charts, and the notices that keep them current. You must know which document is authoritative for which question and how amendments and revisions are controlled. An out-of-date chart is a hazard, not a convenience.
Charts
Be able to read en-route charts, area charts, standard instrument departures and arrivals, approach charts and aerodrome charts. Extract frequencies, minimum safe altitudes, restrictions, gradients, missed approach procedures and declared distances. Understand chart symbols for airspace, obstacles, and reporting points, and how the transition altitude and level are shown.
NOTAMs
NOTAMs are time-critical and easy to misread. Know the structure of a NOTAM: identifier, type, affected facility, period of validity, and the condition described. Be able to tell whether a NOTAM is currently active, whether it starts later, and whether it has been superseded. Understand the difference between a NOTAM and an aeronautical information publication amendment, and why a NOTAM may be the only source for a temporary change.
Traps
Questions often hinge on validity periods: a NOTAM that begins after your ETA does not affect you, and one that ends before your departure does not either. Watch for NOTAMs that modify a chart you are using, and for the trap of assuming a published minimum safe altitude clears all terrain in all directions.
Rule of thumb
Before flight, cross-check every chart you will use against the current NOTAM list for the aerodromes and routes involved. If a NOTAM changes a chart, annotate the chart rather than relying on memory.
