Carefully considered professional answers from a mostly professional pilot:
1. What is the difference between Vra and
Vb?
Vra is clearly the vertical speed of the rain; typically about 8kias depending on droplet size.
Vb is the speed at which the pilot is proceeding; typically about 100k less than current speed of the aircraft.
2. You are in a turbo-prop coming in fast, what is the proper landing technique?
Undertake conversion to a faster aircraft.
5.You are flying from A to B and begin to experience -FZRA, what should you do?
In the event of unexpected FZRA, company SOPs will require you to contact the Dispatch Office and the Duty Engineer, who will evaluate your manhood. A note will be made against your permanent record.
8.Thunderstorm detection while in cloud w/ precip. not sure but I think its harder to detect t-storms cos of attenuation
Best way to detect thunderstorms while in cloud is to rest your fingertips against the cockpit side windows and carefully feel for the turbulence. If the left wing experiences greater G forces, turn left; or vice versa.
