Cross-Country Flight Planning Flashcards
Take me through this line on your XC nav log, show me how you calculated each number.
Ok
How did you calculate your initial climb TAS?
Ok
Define IAS, CAS, TAS, GS.
Ok
Are the airway courses depicted on the low enroute chart magnetic or true?
Ok
Where and how did you calculate our IFR fuel reserve?
Ok
Approaching the INW VOR, ATC tells you, “Cessna 976SP, due to delays at KABQ you can expect to hold over the INW VOR for approximately two hours. Advise if able to accept.” Will you accept?
Calculate the expected fuel burn and determine whether, after holding for two hours, you would still have enough fuel to continue to KABQ then fly for 45min at normal cruise. The math is straightforward: multiply your cruise GPH by 2 and subtract this number from your original total fuel remaining. Make sure that this final number is more than 3⁄4 of the cruise GPH.
How do you close your IFR flight plan at towered and non-towered airports?
Contact FSS on the ground or while airborne or call WX brief
Is the phoenix one departure a SID or ODP? Why?
ODP. It says so in the title
What are some of the differences between SIDs and ODPs?
SID:
Provide obstruction clearance and help reduce radio congestion and workload by simplifying ATC clearances.
Pilot Nav SID’s - navigate by charted routes, minimal radio instruction
Vector SID’s - navigation by radar vectors, routes not printed
Some SID’s depict non standard radio failure procedures
File NO SID’s in remarks if you don’t wan them
RNAV SID’s and all graphical RNAV ODP’s require RNAV1 performance
ODP:
ONLY provides obstruction clearance
May be flown without an ATC clearance unless a SID or other instructions are assigned.
Graphic ODP denote “obstacle in the chart title
All new RNAV ODPs are avail in graphic form
Found in front of NACO chart books arranged alphabetically by city
Jepp charts show ODP’s under airport diagram, large airports separate chart
You take off on the PXR1.PXR but right after lift off tower starts giving you vectors. What
minimum climb gradient are you expected to maintain?
Look at the DVA under departure
procedures. In this case 250 ft/nm.
How many ft/min does this translate to if we’re going to be climbing out at a ground speed of about 80kts?
Ft/nm requirement x nm/min
250/ (80/60) = 188ft/min
Will we be able to maintain this ft/min climb to 3000?
Yes
When you see “standard” written on an ODP, what does this mean?
It is referring to the standard visibility weather mins for 121/135. It does not mean 200 ft/nm climb gradient. Hence the reason some ODPs read, say, “Standard with minimum 250 ft/nm climb to 5000.” Clearly this does not mean, “200 ft/nm climb with minimum 250 ft/nm climb to 5000.” The way you can tell that the climb gradient is the standard 200 ft/nm is when it is not depicted at all.
What are standard 121/135 weather mins?
1sm if the plane has 2 or fewer engines; 1⁄2 sm if the plane has more than 2 engines.
Take me through your options for picking up an IFR clearance out of a non-towered airport
National clearance hotline, briefer/FSS, and most common, calling up the controlling agency in the plane while on the ground with the engines started.
Let’s say you wanted to pick up your IFR clearance in the plane at KHII. Who do you call, what frequency would you use, what would you say?
LA Center on 134.65. “LA Center, Cessna 976SP is on the ground at KHII, we’d like to pick up our IFR clearance to KIWA.”
Center gives you a clearance void time. Are you required to be off the ground by that time, or is the requirement that you’ve departed and contacted LA Center by that time?
Just off the ground.
What kind of weather is required to fly the VCOA out of KHII?
1500 AGL ceiling - 3sm vis.
Do you need to inform ATC or will they propose it?
Inform them.
How would you fly VOCA out of KHII? As described in the T/O minimums, ODPs, DVAs section:
After departure, circle back over the airport and climb while circling to at or above 2300ft MSL, then proceed northwest and intercept EED VORTAC R-138 to EED VORTAC, continue climb in EED VORTAC holding pattern (East, right turns, 257° inbound) to cross EED VORTAC at or above 6100 before proceeding on course.
Scenario: Center gives you the following clearance: “Cessna 976SP, cleared to KIWA via EED V12 DRK V105 PXR Direct SNOWL, climb maintain 11,000….” It’s night out, the ceiling is 1000ft OVC, 2sm vis. You’re departing RWY32
How are you going to navigate to EED?
Fly the ODP (posted below).

Let’s say you’re departing during the summer, the temperature is 35C and the altimeter is 29.82. You’re taking off into a slight headwind. Would you fly this ODP? Why or why not?
Convert 492 ft/nm to ft/min. Then calculate your expected ft/min climb rate using the performance charts and confirm that you will safely be able to achieve the required performanc
Do you need a clearance to fly an ODP? What if you are assigned a heading and altitude after departure, are you required to fly
what you’ve been assigned or can you still take the initiative and fly the ODP?
NO
You
must fly what you’ve been assigned.
What does DER mean on the ODP?
