TAKEOFF PERFORMANCE
Refer to the Airplane Flight Manual for a complete set of charts for
determination of the limiting takeoff weights.
EMBRAER RUNWAY ANALYSIS SOFTWARE
Although the AFM presents all the required performance data for
takeoff, the a
mount of options and charts presented, makes their use
very difficult. In order to help operators, EMBRAER developed a
runway analysis software for determination of the limiting weights.
THE TAKEOFF OUTPUT DATA
The program outputs the N1, weight, V
1
/V
R
/V
2
, the level-off altitude
and height, and the code assigned to the limitation detected during the
calculation process. These data are valid for the wind and temperature
associated.
The data are calculated for four reference winds for range of
temperatures
.
The level-off output depends upon the Minimum Level-off Height
entered in the d
ata input. If obstacle clearance requires, a value higher
than the one entered will be automatically output.
NOTE: Level-off height must be corrected for temperatures below
standar
d.
Limitation codes assigned are a number
(1, 2 etc.) for Obstacle limited
weight, R
for Runway limited weight, W for WAT limited weight (same
as Climb or Second Segment), S
for Structural limited weight, V for
V1
min
, L for Level Off limited weight and B for a Brake Energy limited
weight.
If the operation for a specific condition is considered unfeasible or
outside th
e performance tables, the relevant data will be provided with
asterisks.
