SAMRA 14 Flashcards
Rain falling but before get to ground…
Call it VIRGA, could have dry microburst.
-They can often be identified by the presence of “virga”
-They are linked with high-based cumulus and Altocumulus type clouds
-with this type of microburst, evaporative cooling intensifies the downdrafts

GFA CYQX which airport has FZDZ?
CYQX
GFA BKN025 ceiling 1500’, Which airport thick 2500’?
CYHZ
D-icing at least which speed to prevent ice ?
> 500kts to prevent ice
Flying in NAT minimum equipment required?
Need…
Coriolis effect ?
Rotation earth of axis
TS disappearing stage?
Spread downdrafts
Condensation will release what?
Release potential latent heat
The main cooling machine condensation?
Adiabatic expansion
ILS full left to full right, how many degrees?
5°
Thunderstorm severe conditions, what to do?
Increase sever conditions away from the wave crest
50nm Squall line in advance of a cold front, you fly around this area, you will meet ?
SCT cumulus and CB, TCU parallel to the cold front
They have a “special TAF” weather, why?
Come faster
Jet stream change direction because?
Low pressure
LLJ find in low or high pressure
Low pressure
Descend air be compressed, why?
Because around air have higher pressure (more dense)
Warm front with snow ice pellets, what to expect?
FZRA
Radio ground wave
As frequency increases attenuation increases
Position A?
Jet stream cloud
IFR prefered route
IFR start or end with NAV AIDS
Clear sky night, light winds, dewpoint close of temperature, what can you expect?
Radiation fog can _______ visibility
Radiation fog will be ?
In calm wind will be more thick
Radiation fog difficult to detect because?
Radar energy attenuation
Blind person need?
An individual briefing, don’t need emergency.
Cold air mass will?
Cold air front steeper and advance quickly
If they have FOG above the sea, but no FOG on the ground?
Warm moist air, off shore wind
GFA LLJ
Low pressure blocked by high pressure
FL340
250mb = 340
Thunderstorm avoid to turn?
