80% Torque
lower nose
220 KIAS
Climbing turn to 60º bank
allow nose to fall through horizon while increasing to 90º bank
passing through horizon begin decreasing bank
maintain wingtip on horizon bar while rolling wings level back to level fight
Describe instrument aileron roll procedures
Set power at 80% to MAX
Low nose to attain 220 KIAS
Return to straight-and-level at 220
Smoothly pitch up to 25º nose up
Smoothly roll so wings are level as fuselage dot passes the horizon
Maintain back pressure to maintain approx. 1G
The EADI will declutter when pitch or roll values exceed
____ or ____ pitch
____ bank
+30º ot -20º pitch
over 65º bank
Red chevrons will appear on the EADI if aircraft attitude is between ___º and ___º nose up or down
40º and 90º
What is the difference between Vertical “S” A B C D?
A: constant heading
B: constant bank (usually 30º)
C: bank reverses direction after each climb and descent cycle
D: bank reverses after each climb or descent
What is a radial?
Magnetic bearing from a station referenced in degrees
When navigating via GPS, full scale deflection of the needle indicates how far off course?
5 NM
When navigating via VOR, how far off course is the aircraft when the needle is fully deflected?
10º
If you have immediately passed a VOR station and want to intercept your course, how much intercept angle should you use if you are 15º of course?
15º
At station passage, use intercept = to degrees off course
What is the name of the angle between the intercept heading and the desired course?
Intercept angle
How many radials per NM are there if you are flying on the 15 DME arc?
4
use 60:1 rule
60/15(DME) = 4
You are arcing on the 20 NM arc, and will intercept the 360º course outbound. Your groundspeed is 150 knots. Using the 1% of your groundspeed technique and using the nearest whole degree, you should begin your turn when the head of the bearing pointer passes ______
175º
1% of 150 Knots GS = 1.5
1.5 x (60/20nm) = 4.5 (or nearest whole) radials
The Vertical “S” C direction of turn is reversed at the beginning of each _________
descent
What is the recovery for a nose-high instrument unusual attitude?
Add power as required
Roll toward 90º AOB, allowing the nose to slice smoothly through the horizon
Roll wings level
What are the steps for proceeding Direct to a VOR?***
- TIM the station
- Turn in the shortest direction and place the head of the bearing pointer under the top of the EHSI index
- Center the CDI with a “TO” indication (pull out the knob)
- Maintain selected course to the station by crabbing into the wind
What are the steps to proceed Direct GPS?
- Select GPS as the NAV mode on the EHSI
- Select the desired waypoint and press Direct To and Enter
- Turn shortest direction to place the head of the magenta bearing pointer under the top of the EHSI index
- When established on the initial heading to the way point, center the CDI with the desired track that coincides with the heading
- Crab into the wind as necessary to keep the CDI centered
What are the Course Intercept Procedures?
- TIM the station
- Set the desired course in the course select window and check for a correct TO-FROM indication
- Turn in the shorter direction toward the CDI (the actual CDI, not to be confused with the course needle)
- Inbound intercepts: Roll out with bearing pointer between the upper lubber line and the head of the course arrow (use CB+30≤90; where CB is the distance between the Course and Bearing pointers)
- Outbound intercepts: TC+45 (Where Tail of bearing pointer to the course + 45º)
When should the “Double the Angle” method be used to intercept a course?
When close to the station
(Since radials get “packed together” when approaching a station, the CB+30 method may cause the pilot to overshoot the course inbound. The double the angle method allows a shallower intercept angle)
What are the steps you follow in a fix-to-fix navigation?
- TIM the station
- Set the desired radial (set the RADIAL not the COURSE)
- Turn in the shorter direction to a HDG between the head of the bearing pointer and the head of the course arrow
- Visualize the greater fix on its radial at the edge of the compass card
- Visualize an imaginary line from the aircraft present position (on the tail) through the remaining fix
- Slide the line to the center
How do you determine your turn radius? (for flying DME ARCS)
1% of the ground speed
200 KIAS x 1% = 2 miles
What is the formula for intercepting a radial from an arc?
Lead point in radials = (1% Groundspeed) x (60/ARC DME)
Example: At 20 DME and 200 Knots, what is the lead point in radials? (2 nm lead) x (60/20 nm) = 6º lead
How do you correct an arc if you are inside the arc (DME to low)?
Displace the bearing pointer 5º BELOW the reference point for each 1/2 MILE deviation to the inside of the arc
Example: 1 nm in the inside of the arc, put bearing pointer 10º below the 90º reference point
How do you correct an arc if you are outside the arc (DME to high)?
Displace the bearing pointer 10º ABOVE the reference point for each 1/2 MILE deviation outside of the arc.
Example: 1 mile outside the arc, place the bearing pointer 20º ABOVE the 90º reference point
