stump me
 

I'm studying for an interview with XJT. If anyone can post any good head-scratchers on Jep plates or charts, I would appreciate it. I'm not trying to gloat or prove that I know everything because believe me I don't. I just wanted to get some good practice in before the interview. Thanks!

on the jepp low enroute chart what do the lines made up of small telephone handsets represent

1) You're on your way to do an approach into some airport in Mexico where the MSA is 13,000'. They clear you for the approach while you're at 15,000'. When/How would you descend if you need to make it all the way down to 2,000' to land?

2) Where can you find out how much runway you'll have left to stop if you follow the glideslope all the way to the runway before touching down?

That's a communications sector boundary.

1. Without looking at the actual approach it would be hard to give specifics, but generally speaking the MSA is for emergency use only and only gives you 1000 foot obstacle clearance. At 15,000 feet I would probably have to ask for a hold or descend in a published hold until reaching the minimum altitude (2000 feet in your scenario) for that approach segment and then continue with the approach from there.
2. On the back side of the airport diagram there is a block for additional runway information that includes usable lengths when landing beyond a certain point.

These are good questions that have been posted so far. Keep them coming if anyone has more.

What constitutes "mountainous terrain?"

Elevation = 5001 feet or higher

Per Jepp, it is an elevation change of 3000' or greater within a distance of 10 miles.

That's not the FAA definition...the entire Western US (except the San Jaquin Valley) is mountanious per the FAA.

That IS the Jepp definition. Out of curiosity, what is the FAA's definition?
