Need immediate assistance
VOR work principle?
It depends upon a phase difference between 2 signals transmitted simultaneously from a ground station.

cA move to great lake, what will form ?
Steam fog
Fly from CYVR to KFLA ? What icing and turbulence you meet ?
Moderate icing & occasional moderate to severe turbulence.
What is radiation fog?
Radiation cooling, contact with the earth
Fog that forms in the cold air section of a warm front because?
Cold air become saturated from rain falling from warm air
GFA distance between the FZRA and first warm front?
150nm
How to scan with weather radar TS ?
Middle to lower area
TS shows on weather radar an echo up to 90nm ?
The intensity will decrease as distance increase
PSR can be use to?
Detect weather, SSR need transponder, can’t detect weather.
Surface have wind shear, which one is the correct effect?
Increase in A/S
Comment fonctionne le DME
Time difference to determine the distance
The measurement of the time between the transmission of an aircraft interrogating signal and the receipt of a matched pulse reply signal from a ground station (the 2 signals having different frequencies)
Flying through the jetstream, temperature drop, if you want to avoid the jet stream, what would you do ?
Descent
How many satellites for 3D view?
4
What cause Coriolis force
The earth’s rotation axis.
Where you can find rotor cloud?
Left side (downwind)
A warm and stable air mass go through rocky mountain will form Pacific ocean?

Isotach chart, counter line, altitude gradient?
Slope of the pressure surface
For TCAS and ACAS resolution advisory, how to do?
Manœuvre first, then tell ATC, return back to route.
The reason for steam fog ?
Raising dewpoint and temperature
Fly from cold air (-20°C) descent to an airport at (-9°C dewpoint 8°C) what will happened?

Increase slightly then decrease
Why the temperature decrease slower when saturated air ascending than the unsaturated air will?
Release heat when condensation
In what temperature its easiest to accumulate ice ?
0° to -25°C
The vertical distance between any two specific pressure level is ?
Distance is less in cold air
Flight low level to a warm front, precipitation changes from steady rain to the showers is ?

FL350
Mb
250mb
Pilot forget to set 29,92 from 30,22 climbing FL180 to FL220, after reset, the ATC contrôler will?
Nothing because the subscale is not geared to the encoding altitude read-out
