TECHNICAL QUESTIONS
Dear All,
Here are some questions i was unsure about and thought i post it up for the professionals to take a whiff at it.....
1. What is the difference between Vra and Vb? i think one is rough air penetration speed and the other is turbulent air penetration speed
2. You are in a turbo-prop coming in fast, what is the proper landing technique?
3. You are about to cross a Jet Stream with a decreasing temperature .How do you proceed to avoid turbulence?
4. There are embedded thunderstorms behind an area of moderate rain, how will the weather radar be affected?
5.You are flying from A to B and begin to experience -FZRA, what should you do? i think climb
6.You forget to reset your subscale going through 18,000'. What alt will ATC see when you reset it?
7. How do i calculate SGR or SAR?SGR is GS(TAS+or-wind) vs FF hence formula is FF(lb/nm)/GS(Nm/hr)=Lb/nm and SAR is TAS vs FF so i think
8.Thunderstorm detection while in cloud w/ precip. not sure but I think its harder to detect t-storms cos of attenuation
9.What happens when precip falls onto a cold soaked wing? i think its a recipe for clear ice formation
10.When is your True Altitude lower than Indicated. i think its when temp or pressure is lower than ISA
11. What is the formula for calculating critical point? CP=DH/O+H
D=total sector distance, H= ground speed home, O= ground speed out
Time to CP= Distance to CP/O

Jack says we have to be serious, so here goes:
Flare, but only a little bit. Slow down, taxi, park. Submit the paperwork. Update the CV. Get a job with Cathay.
(Some pilots prefer to slow down before landing, to avoid the Cathay scenario. But hey, each to their own.)
Do whatever you like. In a turboprop you'll be descending quite soon, regardless of the decision.
I don't know how my UNS-1 calculates it. But in my last job, I knew how my Garmin did it. It was with GS and distance to each place.
Cold or low, look out below. (That's cold temp and low pressure, btw.) That's why Canadian and Antarctic aircraft have skis on the bottom - in cold weather, they sometimes fly so low, they bounce off hill tops. Skis make for soft bounces.
I'd better leave some unanswered for all youse blokes, so you don't feel left out an' all.

6.You forget to reset your subscale going through 18,000'. What alt will ATC see when you reset it?
4. There are embedded thunderstorms behind an area of moderate rain, how will the weather radar be affected?
11. what is the formula for calculating critical point?

Come on guys. The troll is click-baiting for professionals!
What one puts into a Kollsman window has no effect on SSR displays. Transponders transmit pressure altitude and ATC computers apply a QNH correction.
For extra excitement, fly on 1013 at all times and level out at a mentally-calculated pressure-corrected altitude when below transition. See if anyone notices.

Frost forms by sublimation, not by precip falling. Typically, the sky is clear when it forms.
Carefully considered professional answers from a mostly professional pilot:
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.
Undertake conversion to a faster aircraft.
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.
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.
1. What is the difference between Vra and Vb?
2. You are in a turbo-prop coming in fast, what is the proper landing technique?
5.You are flying from A to B and begin to experience -FZRA, what should you do?

You are about to cross a Jet Stream with a decreasing temperature .How do you proceed to avoid turbulence?
Always bank left in the south and right in the north. Because of Coriolis and stuff.
Also, I always thought Vb was the rate of progression of beverages towards the flight deck? It's inversely proportional to the proximity to ToD. Often confused with Vdt, the rate at which the captain opens the Daily Telegraph after ToC.
! Shame on you. It's the Prantle-Meyer effect.
Even after (not if) he (it must be a he, no woman would be that dopy) looses control, having flown into the freezing rain, and is now pointing straight down, he will have to really try very hard to have a Prantle-Meyer fan come into the equation.
Mind you, there is that other well known fan that something hits under such circumstances.
Tootle pip!!

9.What happens when precip falls onto a cold soaked wing? i think it forms frost or melts the frost formed
10.When is your True Altitude lower than Indicated. i think its when temp or pressure is lower than ISA
11. what is the formula for calculating critical point?
12.What happens when precip falls onto a cold soaked wing? does it melt the frost or causes more ice?
