Weight and Balance
This is the total weight of an item multiplied by its distance from a reference datum.
What is a moment?
Adding baggage to the rear compartment will usually move the center of gravity in this direction.
What is aft?
In a METAR, BKN020 means this type of cloud coverage at this altitude.
What is broken clouds at 2,000 feet?
This weather advisory is generally for weather that may affect all aircraft, but especially smaller aircraft.
What is an AIRMET?
A METAR showing low ceilings and poor visibility would most likely describe these flight conditions.
What are IFR conditions?
This fixed reference point is used to measure all arms in weight and balance calculations.
What is the datum?
Removing fuel from a tank located behind the datum would generally cause total weight to do this and CG to possibly shift this direction.
What is decrease and move forward?
If the ceiling is reported as overcast, this many 8ths of the sky is covered.
What is eight?
This advisory is issued for significant weather hazards such as severe icing, severe turbulence, or dust storms.
What is a SIGMET?
If the temperature and dew point are close together, the air is likely this.
What is nearly saturated?
This term describes the distance from the datum to the location of a loaded item.
What is the arm?
When a pilot moves a passenger from a rear seat to a front seat, this happens to the CG.
What is it moves forward?
In a METAR, A2992 refers to this altimeter setting.
What is 29.92 inches of mercury?
AIRMET Sierra is issued for these weather conditions (include two).
What are IFR conditions and mountain obscuration?
This weather phenomenon becomes more likely when temperature and dew point are very close, especially in the morning.
What is fog?
This is found by dividing the total moment by the total weight.
What is the center of gravity?
An aircraft can be under max gross weight but still unsafe because it is outside these limits.
What are center of gravity limits?
GR means this in a METAR.
What is hail?
AIRMET Tango warns pilots about this type of hazard.
What is turbulence?
A pilot reading a TAF with strong gusty winds should anticipate this possible flight challenge on takeoff and landing.
What is a crosswind or gust control issue?
If an airplane’s center of gravity moves too far aft, this may happen, making stall recovery more difficult.
What is reduced stability?
This formula is used when determining how far an item must be moved to shift the CG to a desired location: weight shifted times distance moved equals this.
What is the change in moment?
"Unknown precipitation began 11 minutes past the hour and ended 12 minutes past the hour" is written like this in a METAR.
What is UPB11E12?
AIRMET Zulu is associated with this major weather concern.
What is icing?
The Convective SIGMET wind threshold is this.
What is 50 knots or great?
