General Flashcards
What is the difference between heading and track?
Heading: the direction in which the longitudinal axis of an aircraft is pointed.
Track: The projection on the earth’s surface of the path of an aircraft.
Heading is the direction the nose is pointed, track is the aircraft’s track along the ground. The difference between the two is called WIND DRIFT.
What is the standard lapse rate?
3.5 degrees F
2 degrees C
NOTE: Although this is used as the “standard” for performance charts, etc, the ENVIRONMENTAL lapse rate will many times be different.
What is the International Standard Atmosphere (ISA)?
Pressure: 29.92”
Temperature: 59 degrees F (15 C)
How much does atmospheric pressure decrease every 1000’?
1” per 1000’
What are the four altitudes?
Indicated
Pressure
Density
True
How do you find pressure altitude?
Set 29.92” in the Kollsman window.
What are the effects of a non-standard lapse rate on airplane performance?
If the lapse rate yields a warmer temperature than standard at that altitude, airplane performance decreases. If the lapse rate yields a colder temperature than standard at that altitude, airplane performance increases.
Define VFR, MVFR, IFR and LIFR?
VFR = >3000′ and >5 miles
MVFR = 1000-3000′ and/or 3-5 miles
IFR = 500-1000′ and/or 1-3 miles
LIFR = <500′ and/or <1 mile
Are the ceilings in METARs and TAFs in AGL or MSL?
The report will show ceilings in AGL. So you have to add that number to the airport elevation to get the MSL number (the number the altimeter will read).
What are the time limitations of a Medical Certificate?
1st Class (ATP): Every 12 months if younger than age 40, Every 6 months over 40
2nd Class (Commercial Pilots): 12 Months
3rd Class (Private / Student / Recreational Pilots):
2 Yrs if Over 40 Old
5 Yrs if Under 40 Old
Every 0.01” increase on the altimeter is equal to how many feet?
10’
Cool, sinking air =
Warm, rising air =
Cool, sinking air = High Pressure
Warm, rising air = Low Pressure
