Pattern Flashcards
Final turn speed Flaps landing
110 KIAS or on speed AOA
Final airspeed Flaps landing
100 KIAS or on speed AOA indication
When should landing flaps be used?
heavy weight flaps up landing distane is equal or greater than 80% of runway length
When are landing flaps not recommened, and why?
Crosswind greater than 10 knots, due to the potential stresses the side loads impart on the landing gear.
What is the landing flaps limiting crosswind?
25 knots
Final turn speed Flaps TO
115 KIAS or on speed AOA
Final airspeed Flaps TO
105 KIAS or on speed AOA
When are flaps TO recommended for full stop landings?
Greater than 10 knots crosswind. May be used in gusty winds
Final turn speed Flaps UP
120 KIAS or on speed AOA
Final airspeed Flaps UP
110 KIAS or on speed AOA
When may Flaps UP be used for full stop landings?
Crosswinds greater than 20 knots and landing distance is not a factor
Inside downwind airspeed
(min) 120 KIAS
Inside downwind torque setting flaps: UP-TO-LDG
30-35-45%
Inside downwind (120KIAS) pitch attitude flaps TO or LDG
1/4 ground, 3/4 sky
Inside downwind (120 KIAS) pitch attitude flaps up
Spinner on horizon
Final turn pitch attitude Flaps TO or LDG
2/3 ground, 1/3 sky
Final turn pitch attitude flaps UP
1/2 ground, 1/2 sky
Aimpoint pitch attitude flaps UP-TO/LDG
1/3 up windscreen - 1/2 up windscreen
Touchdown airspeed target and range flaps UP
90, 85-100
Touchdown airspeed target and range flaps TO
85, 80-95
Touchdown airspeed target and range flaps LDG
80, 75-90
Target touchdown zone flaps TO/LDG
1st 1,000 feet
Target touchdown zone flaps UP
1st 1,500 feet
What may raise the final approach and touchdown speeds?
- Gust (up to 10 knots)
- Aircraft weight
- Outside air temperature
Initial: airspeed
200 KIAS
Initial: altitude for normal overhead
1,000 - 1,500 feet AGL or according to local directives
Break: airspeed (start and slow to)
200 KIAS to 120-150 KIAS
Break zone
Between approach end and 3,000 feet down the runway
Minimum airspeed inside/closed downwind
120 KIAS
Drift correction on inside/closed downwind
Approximately twice the correction used on initial
Perch point for a no-wind pattern
Threshold ≈45° off your shoulder
When are you not allowed to perch?
- Another a/c in the final turn is not in sight
- A straight in is inside 2 miles and not in sight
- ELP inside low key and normal spacing cannot be maintained
- Pattern spacing cannot be maintained within the normal ground track
- Not properly configured by the perch point
When will the on speed AOA normally be higher than the final speed?
When above 700-800 lbs of fuel, add ≈ 3-5 knots to final turn and final
When do you descend to 500’ AGL during a straight-in?
Before the 5-mile point
When must you be configured on a straight-in?
Prior to 2 mile point
What should have happened approximately 4 seconds after touchdown?
N1 reduction from 67 to 60-61
Closed pull-up min airspeed and max bank
140 KIAS, 90°
When can you not request closed?
- Between “report high key” and a/c at low key
- A/C orbiting high key
- A/C 5 and 2 miles
- Traffic on inside downwind, not abeam
- A/C on initial has not begun their break
When can you not break?
- A/C straight in between 5 and 2 miles
- A/C between “Report high key” and low key
- A/C orbiting High key
- Directed to carry straight-through
- Unable to maintain spacing with a/c already established on inside/closed downwind
Max angle used in final turn
45° - if above a go-around should be executed (11-248 §5.8.3.7)
