1.15

Question 8

Low altitude enroute charts are intended for use up to, but not including ____________ feet MSL.

Answer 8

18,000’

Question 9

Define MEA

Answer 9

Minimum Enroute Altitude.

Lowest published altitude between radio fixes that ensures acceptable navigational signal coverage and meets obstacle clearance requirements between the two fixes.

Question 10

Define MOCA

Answer 10

Minimum Obstruction Clearance Altitude

Same clearance as an MEA, but only guarantees coverage within 22NM of a radio fix

Lowest published altitude between radio fixes, off-airway routes, or route segments that meets obstacle clearance requirements for the entire route segment and only ensures signal coverage within 22NM of a NAVAID

Question 11

What does MRA stand for?

Answer 11

Minimum Reception Altitude

Question 12

What does MCA stand for?

Answer 12

Minimum Crossing Altitude

Question 13

What does MAA stand for?

Answer 13

Maximum Authorized Altitude

Question 14

Define OROCA

Answer 14

Off Route Obstruction Clearance Altitude

Provides obstacle clearance within 4NM of a route of 1,000’ in non mountainous terrain, and 2,000’ in designated mountainous areas of the United States.

Does NOT guarantee any signal coverage

Question 15

You are planning an IFR flight and while planning an approach, need to find out if the NAVAIDs associated with the approach are monitored or not.

-What would be the two primary methods of finding this information?
-Why is it important?

Answer 15

• IFR Supplement and NOTAMs
  -If unable to apply the VFR Exception rule in regards to an approach, you will need to plan on for an alternate.

Question 16

When planning to land at an alternate location during an IFR flight, how do you determine how much fuel and time is required?

Answer 16

Start planning from the MAP of your primary, executing the missed approach procedure, doing one turn in holding, then proceeding directly to the IAP/IAF of an approach at your alternate, and landing to the runway.

IFR reserve is not included in the calculation.

Question 17

Under what conditions is a procedure turn not required?

Answer 17

-No PT is depicted
-radar vectoring to final
-PT is not authorized

contact ATC when in doubt

Question 18

What are the air speeds associated with the aircraft approach categories?
Which category(s) can army aviators reduce the minimums for?

Answer 18

A) 0-90 knots
B) 91-120
C) 121-140
D) 141-165
E) >165

minimums can be reduced for Cat A ONLY (including the presence of a COPTER approach)

Question 19

How much can visibility minimums be reduced for instrument-equipped helicopters?

Answer 19

Reduced by 1/2 the published minimums but no less than 1/4 SM or 1,200 RVR

Reduction of COPTER approaches is not authorized

Question 20

Clouds with vertical development-such as cumulus, towering cumulus and cumulonimbus-are indicators of what?

Answer 20

Atmospheric instability and possible turbulence

Question 21

If necessary, an aviator flying in turbulence may request what from ATC?

Answer 21

A Block Altitude Clearance

Question 22

What is precipitation static and what is its most common cause?

Answer 22

Distortions of radio waves that interfere with normal reception

Caused by static electricity generated on the various aircraft surfaces in flight that are discharged onto other surfaces and/or the air

Question 23

What is the accuracy of a VOR?

Answer 23

+/- 1 degree, no more than 2.5 degrees

Question 24

IFR flight will not be attempted if there is a VOR error of :

Answer 24

+/- 4 degrees on ground
+/- 6 degrees while airborne

Question 25

Reliable DME signals can be received up to _____ nautical miles at ________ ___ ________.

Answer 25

199 NM
Line of sight altitude

Question 26

For CH47 pilots, when may GPS be used as a substitute for ADF, VOR, and DME receivers?

Answer 26

-flying a DME arc
-flying to or from an NDB or VOR
-determining aircraft position over NDB or VOR
-determining position over a fix defined by NDB bearing crossing a VOR course
-holding over NDB or VOR

Question 27

The aviator is required to request an amended clearance if ATC issued a clearance that :______________?

Answer 27

Would cause an aviator to deviate from a rule or regulation or place the aircraft in jeopardy.

Question 28

Describe a Diverse Departure

Answer 28

Climb runway heading to 400’ above departure end of runway, then turn direct to the first filed point and climb to appropriate altitude unless clearance specifies other instructions

Question 29

Position reports given to ATC should contain the following items:

Answer 29

-ID
-position
-time
-altitude
-Type of flight plan
-next reporting point and ETA
-name of the next succeeding point along flight route
-pertinent remarks

Question 30

If an inadvertent thunderstorm is encountered, is it typically better to maintain the current course or to execute a course reversal?

Answer 30

Maintain current course ; turning maneuvers could extend the time in the storm and will place greater stress on aircraft components.
inadvertent thunderstorm encounters are not typically large storm cells
request assistance from ATC before an actual distress or emergency condition develops
