Regarding horizontal vs. vertical development, the best is ___.
Big and complex with towers.
What is a funneling feature?
A funneling feature is an aid that helps track your eyes onto the point for which you are looking.
What is a limiting or catching feature?
A limiting or catching feature, alerts you when you are at your checkpoint or have flown past it.
What are your 3 options if you are approaching your clearance limit, and can't cancel?
Get a new clearance.
We fly what type of course in JMPS, True or magnetic?
Magnetic. Lambert projection chart remember MAGVAR.

Time Ticks are ___ minute(s) intervals.
Big time Tic Marks are every ___ minutes.
CHUM updates ___ for us.

3 minutes and 40 seconds.
True/False. Do each leg of fuel and round separately before adding them together.
For mission planning purposes, plan the descent down to ___.
EFR is ___?
Estimated fuel remaining at current point.
