Riattacata con MD80 Options

[mimmonick]

Chiedo aiuto agli esperti in quanto non sono riuscito a trovare la checklist per una riattacata corretta.

Quale è la reale procedura di riattacata?

Grazie.

Innazitutto grazie per la risposta. Ho notato però che attivando lo switch TO/GA l'aereo si "impenna" molto. Anche oltre il 20 gradi. E'vero anche che non mi ha mai stallato, però mi sembra eccessivo.

Per quanto riguarda i Flap a 15/15, mi confermi che devo prima raggiungere una minima velocità indicata per poterli retrarre ? perchè da come scrivi sembra che immediatamente da Full Flap devo retrarre a 15/15.

Con gli aerei della aviazione generale il mio istruttore di volo mi ha insegnato la riattacata nel seguente modo:

Interrompere la discesa livellando. Tutto motore per guadagnare velocità. Raggiunta la velocità di salita, cabrare. Retrarre i Flap in accordo con quota e velocità.

Non dovrebbe essere simile anche con i liner ?

Grazie ancora.

FGS GO-AROUND (from AZ Conditional Procedure)

This procedure describes the actions required to perform a two engine automatic go-around after landing flap selection.

CAUTION
If go-around is initiated after runway contact, manual go-around procedures must be used.

NOTE
The autopilot "minimum abort height" was determined to be 20 ft GND when using normal go-around procedure and with both engines operating. "Minimum abort height" is defined as the minimum altitude for initiating go-around without a Wheel strike.

After "Go-around" is ordered or announced:

TO/GA Buttons/Thrust Levers . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . PUSH/ADVANCE 1/2

PF push TO/GA button and manually advance thrust levers to GA EPR.

NOTE
If TO/GA button is pushed when flaps/slats are not in landing configuration, the autopilot will disengage and only FD go-around guidance is available.

Autopilot will roll airplane to wings level and rotate it to a pitch attitude to maintain go-around reference speed (maximum p itch attitude is 20° airplane nose up). Airplane will maintain heading existing when bank angle is less than 3°
Autothrottle FMA's change from SPD (plus selected value) to EPR GA, arm mode goes blank, and roll and pitch annunciators display GO RND. The fast slow pointer on each ADI will provide speed guidance during go-around.

NOTES
• When pressure on the thrust levers is released, the autothrottle system will refine the go-around thrust setting
• The thrust rating computer automatically changes the go-around (GA) if not previously selected.

FLAP/SLAT Lever . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . IMMEDIATELY 15/EXT 1/2

On PF command, PNF move flap/slat lever to the 15/EXT position.

NOTES
• If the airplane touches down momentarily after engagement of auto pilot go-around, the autopilot will remain engaged. The autopilot disengages if the go-around mode is selected after runway contact is made.
• Rudder control will remain in parallel mode, until go-around mode is disengaged, to provide engine out compensation if required.

Landing Gear . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . RETRACT 1/2

On PF command and after a positive rate of climb has been established, PNF move the landing gear lever to UP. Observe la nding gear light indications are normal.

Alt Preselect Knob . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . PULL 1/2

PNF pull the alt preselect knob to arm missed approach altitude capture.

Airspeed/SPD MACH Readout . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . CHECK/SET 1/2

PF verify speed at or above go-around speed, x-checking air speed indicator and ADI. PNF select 250 knots on speed readout.

SPEED BRAKE Lever . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . DISARM 1

Continue as per normal takeoff operations.

TWO ENGINE GO AROUND . . . . (MANUAL)

This procedure describes the actions required to perform a two engine go-around without FGS while in flight or after contact has been made with the runway.

After "Go-Around" is ordered or announced

Attitude (20 ° Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ACHIEVE PF

Rotate the airplane to go-around attitude.

Thrust Levers . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ADVANCE PF

Manually advance thrust levers to GA EPR. If contact with the runway has occurred, verify spoilers retract.

NOTE
Spoilers will be retracted automatically when the thrust levers are advanced.
If ATS is engaged, push TO/GA button while advancing thrust levers.

FLAP/SLAT Lever . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . IMMEDIATELY 15/EXT

PF call "Flap 15". PNF acknowledge "FLAP 15" and move the flap/slat lever to 15/EXT then observe flaps position pointers showing 15/15 and report "Flap 15/15".

GA Thrust . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
CHECK

PNF adjust thrust levers as necessary or verify ATS adjusted thrust to desired EPR and announce "Go-around thrust set".

As soon as positive rate of climb is established PNF announce "Positive climb". PF check for positive rate of climb and call "Gear up". PNF acknowledge "Gear up" and move the landing gear lever to UP then observe landing gear lights off and report "Gear up- Lights
