T3 PPC Flashcards
Who is responsible for ensuring the aircraft limitions and capabilities are not exceeded?
The PC
The same PPC data will suffice for consecutive takeoffs and landings, when?
Perameters have not changed 1,000 lbs,+ 10 degrees, + 1000 ft PA
What is a validation factor?
The validation factor is a torque value that will correspond to the maximum allowable gross weight for the mission profile.
What is the maximum power authorized for premission planning at departure/arrivals below 40 KCAS?
Intermediate Troque Available
What is the purpose of performance planning?
Provide best performance for the CH-47
What are the conditions for the data listed?
Under the title for each chart
On the torque available chart, the point where the line bends to the left position represents what?
Max available due to NG limitation
What does the Vne line on the cruise chart represent?
Structrual Limitations
What do the torque available charts provide?
Available engine torque based on PA and temp
Maximum gross weight to hover chart is used to provide what?
Upper Chart: Max Structural Limit, Lower Chart: MAX GW IGE/OGE
What does the GO/NO GO provide?
If there is sufficient power to attempt OGE manuevers
The airspeed operating limits chart is used to determine an airspeed limit based on what?
Structural limit or blade compressibility, whichever is lower
What does Max R/C and END airspeed provide?
Greatest distance with fuel available
What does the Max Range airspeed provide?
Greatest distance with fuel available
What does MIN and MAX single engine airspeed provide?
MIN and MAX airspeed that can be flown with or without a load
What should be considered when selecting cruise airspeeds?
Not in excess of 44/45 or Vne lines on cruise chart
What is drag factor used for?
The amount of additional torque required to carry an external load
Max gross weight continuous power is based on what?
Airspeed, Pressure, Altitude, and Temp
What can you adjust on the cruise chart to meet mission requirements?
Airspeed/Gross Weight
What does the MAX gross weight SE from the SESC chart tell you?
MAX weight that SE flight can be maintained based on MAX R/C and Endurance KCAS and 100 FPM climb
The maximum allowable GWT for mission profile is based on?
Either structural limit or power limit for the entire mission
What can be added back into the MAX MSN profile GWT?
Expendables that will be used prior to reaching highest altitude/temp
What chart and condition is used to calculate the MAX gross weight for MSN profile TRQ?
The hover chart and forecast conditions at the time of departure
