Définition dewpoint
A dewpoint can indicate water amount, better than relative humidity.
Point de rosée est la température, à une pression donnée, à laquelle doit être refroidis, pour qu’il y est saturation.
Above tropopause temperature will?
Stay the same whatever altitude.
Processus adiabatic
Expansion or compression
Coastal area, mouth of deep valley, strong wind
Funnel effect
Flying along the Earth’s surface Frome areas of higher pressure into converging at an area of low pressure?
Low pressure = convergence
What caractéristiques have LLJ
Below 6000’
Above 50kt
Airmet definition
Weather who’s not appear on GFA
Sigmet appear when?
Dangerous weather for pilot
Where large supercooled water droplets can develop?
Lower levels of cloud that as form in unstable air. Where temperatures are only few degrees below freezing level.
“Increase height with not far away below freezing level”
What does mean CCA in a METAR?
Correction
SIGMET NC mean?
No change
Microburst downdrafts performance?
Decrease AOA and lift
Describe VOLMET
In CFS
Same pressure gradient+ wind stronger in
High pressure system
Upper chart line is ?
Isotach
MLAT (multilateration) is?
Increase air trafic of aircraft and vehicule on the ground. From mode A, C, S transponder. Function in principle known as time difference of arrival (TDOA) transponder return.
WAAS Notam LNAV/VNAV U/S. If aircraft have _____ can do the approach if ?
LNAV & BARO
GAS
ICAO standard lapse rate
The saturated laspe rate
You enter in thunderstorm, what to do?
If can not escape, keep altitude and adjust proper throttle. Don’t turn back. Slow to turbulence penetration speed. Do not attempt to maintain rigid altitude or airspeed. Maintain present heading.
Don’t choose “maintain altitude, reduce to Va”
