Flight Instructors Training Procedures _revised AIC_x

c. The steady wind correction should be bled off approaching the threshold but
the gust factor carried into the landing round out.
d. Note that only the wind and gust factors are added to the Vref for the Vapp.
Allowance B:
a. Adjust approach (Vapp) and Vref airspeed by adding a wind additive of the
greater of the following (not to exceed 10 knots): 5 knots; ½ the steady
wind in excess of 15 knots; or the gust factor.
b. Practical example:
Wind 20kts gusting 30kts.
Aircraft is a Cherokee 140.
Normal approach speed with two notches of flap is 75kts.
Vs1 is 48kts.
Vref (1.3 x Vs1) = 63kts.
Wind additive the greater of the following but not more than 10kts:
5kts; or
½ the steady wind in excess of 15 knots = 2.5kts (5÷2 = 2.5); or
the gust factor which is 10kts.
Thus wind additive = 10kts.
New approach speed + wind additive = 85kts.
New Vref = 73kts.
v. Wind gradient.
vi. Wind gust effect (see par iv. above).
2.11. WHEEL LANDINGS (Applicable to tail wheel aircraft):
i. Technique.
ii. Advantages.
2.12. OVERSHOOT PROCEDURE
i. Go-around procedure.
ii. Missed approach procedure.
GO-AROUND PROCEDURE
i. Apply go-around power – engine considerations.
ii. Rotate into climb attitude – best angle of climb/rate of climb speed.
iii. Flaps – select optimum climb setting.
iv. Check altimeter for positive rate of climb.
v. Undercarriage – Up (if applicable to aircraft type).
vi. Accelerate to best angle of climb/rate of climb speed.
vii. Trim aircraft.
viii. 300 ft agl. after take-off checks.
ix. Accelerate to best rate of climb speed.
2.13. TOUCH AND GO LANDINGS
i. Keep straight on centreline of runway after touchdown.
ii. Select; Flaps as required – confirm position. Trim as required.
Engine considerations – Carb. Heat etc.
iii. Throttle – open smoothly to maximum power – temperatures and pressures.
iv Continue with normal takeoff and after take-off procedures.
