Q

What simple and fundamental weight check can be made by all pilots before flight? (FAA-H-8083-25)

A
  • A useful load check can be made with mental claculation
  • Pilot is familiar with the aircraft’s limits and knows that unusually heavy loads are not aboard.
  • The pilot needs to know the useful load limit of the particular aircraft.

Q

If the useful load limit is not stated directly, what can you do?

A

simply subtract the empty weight from the maximum takeoff weight.

Q

What factors would contribute to a change in center of
gravity location during flight?

A
  • The operator’s flight manual should show procedures which fully account for variations in CG travel during flight caused by variable such as the movement of passengers and the effect of the CG travel due to fuel used.

Q

How is the CG affected during flight as fuel is used?

A
  • As fuel is burned during flight, the weight of the fuel tanks will change and as a result the CG will change.
  • Most aircraft, however, are designed with the fuel tanks positioned close to the CG~ therefore, the consumption of fuel does not affect the CG to any great extent.
  • Also, the lateral balance can be upset by uneven fuel loading or burn-off. The position of the lateral CG is not normally computed for an airplane, but the pilot must be aware of the adverse effects that will result from a laterally unbalanced condition.

Q

Calculate the new CG for the above aircraft if an
additional 80 pounds of baggage were loaded.

A

Exam Tip: When calculating the weight and balance for your
departure, go ahead and complete the W&B calculations for your
arrival at the destination as well. Also, to demonstrate how thorough
and complete your cross-country flight planning is, calculate
your destination airport takeoff and landing distances at your
ETA/ETD

Q

What happens to Vx and Vy as altitude is increased?

A

Vx’s true airspeed increases as you climb. It means that Vx’s indicated airspeed increases slowly, or stays almost the same, as you climb.

As you climb, your indicated airspeed falls further behind your true.

So, as you climb, Vy’s indicated airspeed decreases slightly.

At the absolute ceiling, your Vx and Vy are the same speed. And by the way, if you try reach your absolute ceiling, it will take you quite a while to get there.

Q

During the enroute phase of flight, the CG moves aft due
to fuel burn or a passenger moving. What effect will this
have on various performance factors such as airspeed,
stall speed, and range?
