Need some help with interview Q's

[Dharmesh1231]

Guys...need help with some interview Q's....will be taking an interview soon.

1. When do you need a T/O alt and when do you need a destination alt. How far does the alt have to be?
2. What is adequate visibility?
3. How to explain RVR? When can you and when can't you take off?

Thanks...really appreciate it. If you can give me some detailed answers that would be really helpful....

1. When the FAR's say you need one.
2. When the visibility is adequate
3. A beam of photons colliding at the speed of light.
4. When the FAR's say you can take off.

He's a little bit jaded.

1. An Alt T/O1 is a reduced thrust takeoff. No need for an alternate. This done to save the engines and lower rebuild times.

2. Adequate vis is being to identify certain markers on the runway. i.e. If you are at the end of the runway and you can see the 1000 foot marker, you know you have 1000 feet of vis. You also have adequate visual reference in flight as well. Same basis applies. If you "break out" and can see the three thousand foot marker, you have you 1/2 mile vis to land.

3. RVR uses a transmissometer to determine how much light is being scattered between two sensors. This equates to RVR values. You will generally need at least two of the three reports to use the data. You can tell whether or not if you able to take off by looking on the back of your airport diagram for takeoff mins.

I think my answers are more correct.

Tarzan, answers 2 and 3 look good, but......

Answer #1 has nothing to do with reduced thrust. He is asking about takeoff and destination alternates. A takeoff alternate is necessary when the weather is below landing mins at the departure airport. The 1-2-3 (+/- 1 hr, 2000 ft ceiling, 3 miles vis) rule applies to the destination alternate.

I think my answers are more correct.

LOL, i'll have to agree! The more vague the better, less chance to dig yourself a hole. Besides, I couldnt translate the other answers.

Next time you have an interview just answer yes and no!!

Jepp's definition for #2:
Adequate visual reference is runway lights and/or markings that allow the pilot to continuously identify the takeoff surface and maintain directional control.
