ANAC Agricultural Pilot Helicopter (PAGH) case studies
ANAC Agricultural Pilot Helicopter (PAGH) · Put your knowledge to work in context.
The ANAC Agricultural Pilot Helicopter (PAGH) credential is a Brazilian civil aviation qualification that authorises a licensed helicopter pilot to carry out aerial application work - spraying, dusting, seeding and related dispensing tasks - in agricultural operations. It is aimed at commercial helicopter pilots who intend to work for agricultural aviation companies or as independent operators, and it is normally pursued after the private or commercial helicopter licence is already held, since the agricultural rating builds on existing flying skills rather than replacing them. The ANAC Agricultural Pilot Helicopter (PAGH) case studies are 5 cases and about 3,889 words.
1Droplet Size Versus Inversion at First Light
You are scheduled to spray a 42 ha vineyard block at 06:20, twenty minutes after official sunrise. The forecast called for 6 km/h wind, but your handheld anemometer reads 1.5 km/h at 2 m and 2 km/h at 10 m, and the temperature has risen 1.2 °C in the last 15 minutes while the dew point spread is only 1.8 °C.

After a heavy landing on uneven ground at a remote strip, the pilot reports that the tail rotor pedals feel 'soft and slightly out of rig', with about 15 mm of extra free travel on the left pedal and a faint periodic vibration at 1,800-2,000 RPM that disappears above 2,100 RPM. There is no visible damage to the tail boom, no hydraulic leak, and the pedal rigging was last checked 40 flight hours ago.
