PAT PRACTICE TEST QUESTIONS WITH ALL CORRECT ANSWERS

PAT PRACTICE TEST QUESTIONS WITH ALL CORRECT ANSWERS What is the Operational MTOGW? - Answer-The lowest of the landing-limited (LMTOGW) and performance-limited takeoff weights. Since the performance-limited weights are valid only for the conditions entered, the Operational MTOGW may not represent the highest weight capability for a particular flight, or even for a particular runway. What does "400 LMC" mean? - Answer-The takeoff performance was calculated for a last minute change (LMC) of up to 400 lb of additional freight. Therefore, the takeoff data does not need to be recomputed if this additional weight is added. Always check the weight and balance manifest in conjunction with this part of the PAT prior to accepting additional last minute freight. How do you determine the airplane's true weight limit at the selected airport? - Answer-Choose All Runways. Also, consider selecting Packs OFF. What is VREF? - Answer-The reference speed for flaps 30 and equal to 1.3 VSO. What is VAPP? - Answer-The reference speed for the final approach segment. During a normal approach, VAPP is equal to the MMS for flaps 25. What does a magenta VAPP mean? - Answer-The tailwind or crosswind operational limit is exceeded for one or more runways. A "+" is displayed next to the out-of-limits wind component for the affected runway(s). On what criteria are the approximate landing distances based? - Answer-• Boeing autobrake performance data which assume constant rates of deceleration for minimum, medium, and maximum braking • Touchdown 1,500 feet from the beginning of the runway • Touchdown speed of VREF minus 3 knots • Ground spoilers deployed manually • Thrust reversers are not taken into account What does a landing distance enclosed by chevrons mean? - Answer-The landing distance exceeds the available runway length. What causes some landing distances to display "RWY NOT USABLE"? - Answer-This appears for one of two reasons: 1. All landing distances exceed the available runway length, even with maximum braking. 2. The available runway length is less than the length required to begin the approach when the RVR is less than 4000. When does a "REQD BRAKING ACTION: FAIR" appear? - Answer-A runway condition other than dry is selected and the crosswind component for one or more runways exceeds 10 knots. The reported braking action must be fair or better because the max crosswind allowed with poor braking is just 10 knots. What action is required when landing on a runway with a "B" next to it on the PAT output screen? - Answer-Required block time: 44 minutes. When a specific combination of conditions is encountered, the airplane must remain chocked for at least 44 minutes, regardless of the degree of braking effort used on landing. An AML entry and a maintenance inspection of the fuse plugs are required. What options are available if the PAT is inoperative for takeoff? - Answer-The PAT is deferrable per MEL, but PAT data is required for takeoff. Obtain a replacement PAT from Maintenance if available. If not, contact GOC for the data or use a PAT from another airplane. Do not remove PATs from other airplanes.
