ATPL Meteorology (050) case studies
ATPL Meteorology (050) · Put your knowledge to work in context.
Meteorology (050) is the theoretical knowledge examination in meteorology that a candidate must pass to obtain an Airline Transport Pilot Licence under the EASA ATPL syllabus. It is aimed at trainee and licensed pilots progressing towards the ATPL, and at holders of a frozen ATPL who need to keep the theoretical knowledge current. The ATPL Meteorology (050) case studies are 5 cases and about 3,128 words.
1Cold-Air ILS Approach at a Mountain Aerodrome
Your twin-jet is on a night ILS approach to Runway 27 at a mountain aerodrome. Aerodrome elevation 1,850 ft, touchdown zone elevation 1,820 ft, ILS decision altitude 2,400 ft (550 ft above TDZE).
