Q

What is Gyroscopic Precession?

A

when a force is applied perpendicular to a spinning rotor the rotor will resist the force where it is applied and the force will manifest 90 degrees later in the direction the rotor is spinning.

Q

Primary Supporting Method

Advantages

A
  • FAA Encourages its use
  • Applies to any airplane: a transferable SKILL
  • Develops good partial panel skills
  • Develops better cross-check technique
  • Doesn’t heavily rely on one instrument

Q

Primary Supporting Method

Disadvantages

A
  • Often confusing at first/difficult to remember what instruments are primary/supporting
20
Q

Control Performance Method

What are your two control instruments?

A
  • attitude indicator

- some indicator of power (RPM, MP)

21
Q

Control Performance Method

Advantages

A
  • Easy to remember
  • Used by the USAF and high performance aircraft
  • Easier to master
  • Teaches pilots to be more in tune with aircraft performance and aircraft capabilities
  • Newer cockpits are designed with this method in mind (EFIS)
22
Q

Control Performance Method

Disadvantages

A
  • Numbers have to be relearned for every aircraft
  • Teaches pilots to have an over-reliance or over-dependence on the Attitude Indicator
  • Partial Panel = Real Emergency
23
Q

What is WAAS?

A

Wide Area Augmentation System

Correction Signal for the US

24
Q

What is RAIM?

A

Receiver Autonomous Integrated Monitoring

A way to determine validity of position

25
Q

If we lose WAAS how does that limit us?

A
  • Cant fly some GPS Approaches
  • Less accurate
  • Must check RAIM
26
Q

What are the different VOR checks?

A
  • Ground
  • Airborne
  • Dual
27
Q

How often are VOR checks required?

A

every 30 days

28
Q

What are the errors associated with the VOR?

A
  • Line of sight
  • Distance
  • Reverse Sensing
29
Q

How do we identify an NDB?

A

Listen to morse code

30
Q

How do we know if we lose NDB?

A
  • No morse code

- rest position

31
Q

How do we identify a VOR?

A
  • Morse code

- G1000 does it for use

32
Q

What does ILS mean?

A

Instrument Landing Systems

33
Q

What does an ILS do?

A

It provides both course and altitude guidance to a specific runway

34
Q

The ILS consists of what 4 components?

A
  1. A localizer providing horizontal (left/right) guidance along the extended centerline of the runway.
  2. A glide-slope (GS) providing vertical (up/down) guidance toward the runway touchdown point, usually at a 3 degree slope.
  3. Marker beacons providing range information along the approach path.
  4. Approach lights assisting in the transition from instrument to visual flight.
35
Q

ILS service volumes

A
  • 18NM from antenna site

- 4,500ft above antenna site

36
Q

ILS errors

A
  • Reflection

- False Courses

37
Q

What is ILS reflection?

A

Surface vehicles and even other aircraft flying below 5,000ft AGL may disturb the signal for aircraft on the approach.

38
Q

What is ILS false courses?

A

In addition to the desired course, GS facilities inherently produce additional courses at higher vertical angles. This can be avoided by flying the appropriate altitudes on the approach charts.

39
Q

What does DME mean?

A

Distance Measuring Equipment

40
Q

What does DME do?

A

It allows the pilot to know the aircrafts bearing and distance TO and FROM the DME station.

41
Q

DME errors

A

DME shows the slant range to the DME station and takes into account horizontal distance from the GPS and add the DME slant range and show a greater distance then there is.

42
Q

What would you use if you didn’t have a DME?

A
  • GPS

- Dual VOR

43
Q

How far away can you use a DME?

A

199NM is possible

44
Q

How many satellites do we need for RAIM?

A

5 satellites for RAIM

6 satellites for RAIM with a backup

45
Q

What are the components of the GPS system?

A
