3.2 PRACTICE TAKEOFF AND CLIMB USING AOA

The use of AOA for takeoff and climb performance will greatly

increase the pilot’s awareness while operating at high angles of

attack and yield safe and consistent results.
For example, if you intend to perform a short field over an obstacle

takeoff there are a number of factors you must consider to arrive at

the proper indicated airspeed for the climb. Changing gross weight,

pressure, altitude and temperature will all have an effect on the

indicated climb speed. On the other hand, once you establish the

correct AOA for the climb, it will be the same regardless of the

factors previously mentioned.
To determine the correct AOA for a climb we need a baseline to start

from. For this example we will figure it out for

V

x

(best angle of

climb). Some aircraft may use two different speeds based on the

aircraft configuration, let’s use the one for clearing an obstacle on

takeoff. Refer to the aircraft manual to determine the configuration

and airspeed for

V

x

considering the following factors:

Identify actual gross weight.

Pressure altitude, at the demonstration altitude.

Temperature, at the demonstration altitude.

Correct Calibrated Air Speed (CAS) for installation errors to

arrive at Indicated Air Speed (IAS).
