Instrument Flight Flashcards
Two methods of attitude instrument flying
- Control and performance: set the attitude using control instruments (manifold pressure, RPM, attitude), check it with performance instruments (others)
- Primary and supporting: depending on the maneuver, different instruments will be used as “primary” vs “secondary”. Can be different to establish than to maintain.
Instrument scan errors
Fixation, omission, emphasis
Unusual attitude - nose high
Add power, drop nose, level wings, return to attitude/heading
Unusual attitude - nose low
Reduce power, level wings, pull up to level, return to attitude/heading
Pitch instruments
Airspeed, attitude, altitude, VS
Bank instruments
Attitude, bank indicator, heading indicator
Power instruments
Airspeed, manifold pressure, RPM
Straight and level - power control
Establish: manifold pressure or tachometer (primary), airspeed (supporting)
Maintain: airspeed indicator (primary), manifold pressure (supporting)
Straight and level - pitch control
Establish: attitude (primary), airspeed altimeter and vsi (supporting)
Maintain: altimeter (primary), airspeed attitude and vsi (supporting)
Straight and level - bank control
Maintain: heading (primary), attitude and turn coordinator (supporting)
Standard rate turns - bank control
Establish: attitude (primary), HSI Trend (supporting)
Maintain: HSI trend vector @ 3 (Primary), attitude (supporting)
Formula - Approx bank angle for standard rate turns
True airspeed / 10 + 5
Formula - Start your roll out (degrees)
Half the angle of bank
Standard rate turns - pitch control
Establish: attitude pitch increased appropriately (primary), altimeter and vsi (supporting)
Maintain: altimeter (primary), attitude and vsi (supporting)
Standard rate turns - power control
Maintain: airspeed indicator (primary), manifold pressure/tachometer (supporting)
Constant airspeed climbs - pitch control
Establish: attitude (primary), airspeed + altimeter + vsi (supporting)
Maintain: airspeed (primary), attitude + altimeter + vsi (supporting)
Constant rate climbs - pitch control
Establish: attitude (primary), airspeed + altimeter + vsi (supporting)
Maintain: vsi (primary), other 3 supporting
Constant airspeed descents - pitch control
Establish: attitude is primary, other 3 support
Maintain: airspeed is primary, other 3 support
Constant rate decent - pitch control
Establish: attitude is primary, others support
Maintain: VSI is primary, other support
Formula - level off
10% of your vertical speed
RNP Standards
Keep within a specified distance from the centerline 95% of the time:
- Enroute = 2nm
- Terminal operations = 1nm
- Approach = 0.3nm
Appropriate Attitude settings for adjusting altitude
<100 feet: half bar width
>100 feet: full bar width

Factors affecting required attitude for level flight
Airspeed, air density, wing design, angle of attack
