NORMAL HANDLING
The aircraft can be flown like a conventional aircraft using pitch attitudes and power settings. The following table gives an idea of the attitudes and thrust settings to use in some phases of flight. Bear in mind that these are average values and will vary at different aircraft weights.
N1 PITCH
T/O Initial CL 13
Accel CL 10
Climb CL 7
Cruise 80% 2
Descent Idle -2
Downwind 57% 6
Final 52% 2
ALPHA FLOOR
Alpha floor is an autothrust mode, however it is also a part of the flight envelope protection. At high angles of attack TOGA thrust is commanded by the autothrust system. Alpha floor is available from lift off until 100 ft RA on approach. It provides protection against stall and windshear and has priority over all other protections. (FCOM 1.27.20 [FLT Controls - Normal Law] & 1.22.40 [Auto FLT - FLT Augmentation]). Alpha floor is only available in normal law.
LOW ENERGY WARNING
In normal law, a warning is included to alert the pilot to a low energy situation. It is not a protection, and occurs before floor operates (FCOM 1.22.40 [Auto Flight - Flight Augmentation]. This warning is only available below 2000 ft radio altitude and in CONF 2, 3 or FULL.
ALPHA LOCK
This protection prevents the retraction of flap from CONF 1 to zero, if speed is too low or AOA is too high (FCOM 1.27.50 [Flight Controls - Flaps and Slats]).
06 - COMPLETION STANDARDS
.
Safe, accurate and confident handling.
.
In normal and alternate laws, maintains heading +/-5, height +/-100 ft and speed +/-10 kt.
.
In direct law maintains heading +/-10, height +/-200 ft and speed within +/-15 kt.
07 - COMMON ERRORS
.
Basic scan too slow.
.
Excessive control inputs (including thrust).

SECONDARY REVERSION DUE TO FCU ALTITUDE CHANGE
A319/A320/A321 FLIGHT CREW TRAINING MANUAL NORMAL OPERATION BRIEFINGS FLIGHT DIRECTOR MODE REVERSIONS 1.02.35 Page 2
REV 21 MAY 98
This reversion is caused when there is pilot action on the ALT selector knob while the aircraft is climbing or descending. It applies equally whether the aircraft is being hand flown or if the autopilot is engaged.
VERTICAL MODE ENGAGED FCU ALTITUDE SELECTION CHANGE VERTICAL MODE SWITCHES TO
CLB, OP CLB, EXP CLB Below current altitude V/S on current V/S
DES, OP DES, EXP DES Above current altitude V/S on current V/S
ALT* active Any change V/S on current V/S
REVERSION DUE TO LOSS OF NAV MODE
This reversion is caused by loss of NAV mode, for example selecting a HDG, or when entering a discontinuity. Again, this applies whether the aircraft is being hand flown or through the autopilot.
