Colombian commercial helicopter pilot PCH theory foundations case studies
Colombian commercial helicopter pilot PCH theory foundations · Put your knowledge to work in context.
This independent study page provides practice for Colombian commercial helicopter pilot PCH theory foundations. Its editorial learning areas include Rotary-wing aerodynamic foundations; Rotor controls and transmission; Powerplant and helicopter systems; Hover performance, loading and margins; Weather mechanisms and reports; Basic navigation, time and fuel; Human factors and decision making. The questions develop subject knowledge and application through worked reasoning, distinctions between competing answers, and practical scenarios. Study the relevant guide before attempting a mixed set, then explain the evidence or calculation that supports each answer. Topics on this exam: Rotary-wing aerodynamic foundations, Rotor controls and transmission, Powerplant and helicopter systems, Hover performance, loading and margins, Weather mechanisms and reports, Basic navigation, time and fuel, and Human factors and decision making. The Colombian commercial helicopter pilot PCH theory foundations case studies are 4 cases and about 755 words.
1A weighted center-of-gravity result
A fictional helicopter loading model gives an initial weight of 1800 pounds at an arm of 100 inches from the datum. It adds 250 pounds of fuel at 110 inches.
189 words, under 1 min2A leg calculation excluding reserve
A fictional navigation worksheet gives a helicopter a 90 nautical-mile leg, a constant groundspeed of 60 knots and a fuel-consumption rate of 16 gallons per hour. It explicitly asks for leg time and trip fuel only, excluding reserve, taxi and all other planning allowances.
178 words, under 1 min3Evidence that conflicts with the preferred plan
A fictional preflight discussion records worsening visibility, a reduced power margin at the proposed landing site and fatigue reported by a pilot. The pilot selects one earlier favorable report and says the flight should continue because previous visits were successful.
193 words, under 1 min4A sling-mass calculation does not establish hover capability
A fictional helicopter loading exercise gives a maximum mass of 2800 kilograms and a current aircraft-and-crew mass of 2200 kilograms, excluding fuel and the proposed external load. Fuel adds 180 kilograms.
