Abbreviations and definitions Flashcards
VASI
Visual approach slope indicator
PAPI
Precision approach path indicator
Inclinometer…..
the ball in the turn coordinator, indicates yaw
Precession….
tendency of a gyro to cause instrument errors due to drift
Yaw string….
string over windshield that should be straight back during coordinated turn
Magnetic declination….
points across the earth’s surface connected by isogonic lines, where poles align
IAS
indicated air speed, which is the speed read directly off the air speed indicator
CAS
calibrated air speed, which is IAS corrected for installation and instrument errors
TAS
is CAS corrected for altitude and non-standard temperature
GS
ground speed, is TAS adjusted for wind (GS decreased into a headwind, increased in tailwind)
Balanced turns is when _______
horizontal life = centrifugal force
Glide ration is ______
distance traveled horizontally vs. vertically
Spacial disorientation is ____________
when motions, forces, visual scenes encountered in flight lead to misleading information being sent to brain.
Condensation nuclei
salt, dust, or microscopic particles that condensation uses to start cloud formation
Air mass source region
Area over which air mass acquires its identifying distribution of temperature and moisture.
Ridge
elongated area of high pressure
