Windshear - Large Jets

[snowbirdbrad]

Hey..

Have a couple of questions I want to throw out there and get some opinions on...just wanted to see what pilots flying the bigger jets with the lastest equipment would say to the following answers...


1. What is the most important instrument to monitor for windshear ...

My answer: on landing: the ASI as it is a direct indication of aoa
on takeoff: if IVSI installed that the IVSI (based on my experience with microbursts in the sim)

2. Why are hydraulic flaps more favorable over electric flaps....

My answer: hydraulic flaps, can travel faster, figure because the hydraulic actuators have more power/strength than an electric motor.

Any feedback would be appreciated

Cheers

Brad

The most important instrument to monitor for windshear is the radio. If there is a report of windshear ahead on approaches, then that already gives you a headsup on what to expect.

But you are very correct about the ASI, as you enter and exit a microburst, or getting winds over the hills, the speed will change. Another good look at item is the wind indication on your ND, which will give you an idea of where the wind is coming from, will it be choppy over the terminals etc..

I don't know about hydraulics being the favorable for flaps, but can you imagine using just electrical motors for flaps on a 747? Must be tough. But it works great on a C152!

snowbirdbrad, the most important instrument is your attitude indicator. Remember your early theory, Pitch + Power = Performance. In a windshear encounter your speed is going to be fluctuating, so you put the aircraft at its best climb angle, apply max power and hang on. Most, if not all, modern jets F/D's supply escape guidance from a windshear encounter. It is based on the best attitude for best climb performance.

Hope this helps, and good luck for your interview!

By the way, love your handle, the Snowbirds are a fantastic team.
