Help With Some Interview Questions

[your_dreamguy]

Hey Everyone,

I have an interview coming up and I'm kind of stumped by about 7 questions that I cannot find the answer for. Can you please help?

1) Grid MORA?
I'm more familiar with government charts, even though I do use some Jepps. I think grid MORA are published on Jepp sectionals but I'm not positive. Also,
how did Jepp determine the grid MORA alt. and what obs cleance does a grid
MORA give you?

2) Climb and Descent Ratios?

What does a climb of 5:1 mean or a descent of 3:1? Are these just used for jets? I think a 5:1 climb would mean, you want to climb altitude of 500 per NM...but I'm not sure.

3) Why is terrain depicted on some approach charts and not others?

I think it's because the terrain for that particular area exceeds the FAA obstacle clearance ratio of 200' per NM with a certain distance. Help?

4) How can you remain on the protected area of a procedure turn if it's based on a compass locator?

5) Limitations of a procedure turn?

Is it only that you must remain with 10 NM of the procedure turn fix...or are there other limitations that I do not know about?

6) Speed reductions in Denver Class B Airspace above 10000' MSL?

The equipment I fly has always been to slow for speed reductions. I do not know anything about speed reductions.

7) Overflight of TSTRMS?

I read in the ASA ATP Test Prep that you should overfly a TSTRM by 1000' per 10 kts. How do you know what the speed of the TSTRM is?

Look forward to your help brothers.

D-Guy,

I better not get fired from my job, because I could only answer 2-3 out of the 7 questions! Who are you interviewing with......NASA?

Anyways, good luck on your interview.

sounds like ExpressJet.

know dem Mexican approach plates too

1) Grid MORA direct from the Jeppesen introduction in front of the plates/charts:

1. Grid MORA values derived by Jepp clear all terrain and manmade structures by 1000 feet in areas where the highest elevations are 5000 feet MSL or lower. MORA values clear all terrain and manmade structures by 2000 feet in areas where the highest elevations are 5001 feet MSL or higher. When a Grid MORA is shown as "Unsurveyed" it is due to incomplete or insufficient information. Grid MORA values followed by a +_ denote doubtful accuracy, but are believed to provide sufficient reference point clearance.

2. Grid MORA (State) altitude supplied by the State Authority provides 2000 feet clearance in mountainous areas and 1000 feet in nonmountainous areas.

jepp grid moras are green if below 14k and red if above also.

5:1 and 3:1 probably refer to 5nm or 3nm /1000' of alt loss

OM PT perhaps an 80/260 or 90/270 PT?

PT are limited to 200kts

no speed restrictions in B airspace above 10k

tstrms wind can be gotten by the FD and seeing the upper winds blowing the storm.

i'll have to look up the terrain jepp ?

hope this helps

my book knowlegde from my instrument oral in June is a little rusty, but if memory serves me correctly, the ASA oral exam guide listed several limitations for the procedure turn:
1) must be within 10NM
2) PT must be to the indicated side
3) must comply with speed and altitude requirements as published on the approach plate
4) absence of the PT barb indicates that no PT is authorized
5) a depicted teardrop PT is the only type of PT authorized
