PPL Aircraft General Knowledge case studies
PPL Aircraft General Knowledge · Put your knowledge to work in context.
Aircraft General Knowledge (AGK) is one of the theoretical knowledge subjects a candidate must pass before being issued a Private Pilot Licence (PPL). It sits alongside subjects such as air law, meteorology, navigation and human performance, and it underpins the practical flying training because almost every pre-flight decision - fuel, mass, performance, systems, instrument interpretation - depends on it. The PPL Aircraft General Knowledge case studies are 5 cases and about 3,041 words.
1Aft Baggage Fix That Is Only Just Enough
A light twin is being loaded for a 2 h 15 min VFR sector. Basic empty mass is 1,450 kg with a moment of 2,900 kg·m, giving a CG of 2.00 m.

At 21:30 local a 28 V single-engine aircraft is in IMC at 7,000 ft, 35 NM from destination. The ammeter suddenly shows -40 A and the alternator field circuit breaker has popped.

A four-seat piston single at maximum take-off mass 1,150 kg is planned from a 1,000 m dry asphalt runway at elevation 1,200 ft. QNH is 1,003 hPa and OAT is 24°C.
589 words, about 3 min4Fuel Monitoring When the Gauge Is an Upper Limit
A piston single is planned for a VFR leg of 2 h 20 min at a cruise burn of 32 L/h. Fuel on board at engine start is 140 L.

During an IMC descent in a non-pressurized single, the pilot reduces power and establishes a 500 ft/min descent from 8,500 ft to 6,000 ft. The attitude indicator shows the correct descent attitude, but the altimeter remains frozen at 8,500 ft and the VSI reads zero.
