Exercise 14 - Spiral Dives Flashcards
1
Q
What is a Spiral Dive? - Steep Descending Turn
A
- Angle of Bank usually greater than 45º
- Nose down attitude
- airspeed increases rapidly
- high load factor
2
Q
What is a Spiral Dive? - Not a self-correcting condition
A
- Combination of nose down and steep angle of bank means that increasing speed simply tightens the turn
- load factor and speed keep increasing until something breaks
3
Q
Recognition - Outside Indications
A
- Steep nose down
- Steep angle of bank
- varies with altitude
4
Q
Recognition - Sound
A
Rapidly increasing speed is audible in some aircraft
5
Q
Recognition - Instrument Indications
A
- Airspeed increasing
- Attitude is nose down and steep bank
- altimeter is decreasing
- Turn coordinator is showing a turn
- Heading Indicator is showing a turn
- VSI is descending
6
Q
Potential Causes
A
- Excessive nose drop in a turn
- Incomplete spin entry
- Disorientation (ex. in cloud)
7
Q
Prevention
A
- If nose drops too far in a turn, roll out right away
- Perform correct entry, not stalling aggressively enough is typically the cause
- Watch the weather, get on your instruments
8
Q
Spin vs. Spiral
A
- Spin is a stalled condition
- Spiral is not a stalled condition
- Pay close attention to the airspeed indicator
9
Q
Spiral Dive Recovery
A
- Throttle to idle
- Level the Wings
- Ease out the dive
10
Q
Spiral Dive Safety
A
- Only instructors will enter, no solo entry
- Wings must be level before attempting to recover
- Aircraft must be eased out of dive
