5. Question
Category: Aerodynamics of Flight - Load FactorsYou have loaded your aircraft with baggage of 90 lbs in its baggage compartment. The baggage compartment has been placarded to a max of 100lbs. If your aircraft experiences a load factor of 3.5 G’s, the total load of the baggage would be…?
CorrectReference: FAA Pilot’s Handbook of Aeronautical Knowledge (FAA-H-80830-25D)
Chapter 5 – Aerodynamics of Flight 5-1
Load Factors 5-33
Note: 90 lb. is less than the amount of placarded weight (100 lb.), so there is no problem with the weight of the baggage.
The positive load factor of 3.5 Gs is within the normal operational limit of 3.8 Gs of normal-category airplanes.
When 100 lb. was set as a baggage limit, in this case, it was a limit of 3.8 Gs which works out to be 380lbs
The baggage weight of 90 lb. is multiplied by 3.5 Gs to get a load of 315lbs which is not excessive in this case.IncorrectReference: FAA Pilot’s Handbook of Aeronautical Knowledge (FAA-H-80830-25D)

Chapter 11 – Aircraft Performance 11-1
Atmospheric Pressure 11-2
Pressure Altitude 11-3

7. Question
Category: Navigation - Performance Charts Time, fuel in ClimbRefer to the Airman Knowledge Testing Supplement for Commercial Pilot (FAA-CT-808-1E)
Figure 10. Fuel, Time, and Distance to Climb
Maximum Rate of Climb ChartAircraft weight 3,200lbs
Temperature 27°C
Airport pressure altitude 2,000 ft
Referring to figure 10. using maximum rate of climb, how much fuel would be used from engine start to 6,000 feet pressure altitude?CorrectReference: FAA Pilot’s Handbook of Aeronautical Knowledge (FAA-H-80830-25D)
Chapter 11 – Aircraft Performance 11-1
Climb Performance 11-6
Performance Charts 11-19
Climb and Cruise Charts 11-21
Note: You must be aware of the conditions attached to the chart
At 3,200 lb., 14 lb. of fuel is required to climb from sea level to 6,000 feet as shown in Fig. 10
From sea level to 2,000 feet, only 4 lb. is required
The net difference is 10 lb. to climb from 2,000 feet pressure altitude to 6,000 feet pressure altitude
The air temperature of 27°C, however, is 16°C over standard temperature (standard at 2,000 feet is 11°C, which is 15°C at sea level minus 4°C for the lapse rate)
There is an increase of 10% for each 10°C above standard as per the notes on the chart
You must increase the 10 lb. by 16% (10×1.16) to get 11.6 lbs.
Then add 12 lb. for taxi, takeoff, etc., which is approximately 24 lbs
As the #2 note in the figure states, a 10% increase equals 11 lbs. and then adding 12 lb. for taxi, takeoff, etc.
Therefore the answer is 23 lbs.IncorrectReference: FAA Pilot’s Handbook of Aeronautical Knowledge (FAA-H-80830-25D)

2) Or you will fly from the station with a TO indication.
Both will result in reverse sensing.IncorrectReference: FAA Pilot’s Handbook of Aeronautical Knowledge (FAA-H-80830-25D)
