Aircraft Landing: Flare Retard


Landing Phase Overview


In commercial aviation, “flare” and “retard” are two key actions during the last seconds before touchdown.


#Retard_flare


1️⃣ Flare


Flare = the pilot raises the aircraft nose

slightly just before touchdown.


Purpose:

• Reduce descent rate

• Achieve smooth touchdown

• Allow main landing gear to touch first


Typical timing:

Begins around 30–50 ft (10–15 m) above the runway.


What the pilot does:

• Pull the control column slightly back

• Increase angle of attack

• Reduce descent rate.



2️⃣ Retard


Retard = reduce engine thrust to idle during the flare.


Purpose:

• Remove lift generated by thrust

• Allow aircraft to settle onto the runway


In Airbus aircraft, the system gives an automatic callout:


“RETARD… RETARD…”


This happens around 20 ft above runway.


Pilots must:

• Pull thrust levers to idle

• Continue flare

• Touchdown.




3️⃣ Typical Landing Sequence (Airbus)


Height Action


100 ft Stabilized approach

50 ft Begin flare

30 ft Increase pitch slightly

20 ft RETARD (thrust idle)

10 ft Main gear touchdown




4️⃣ Why the Order Matters


Flare first Retard second


If thrust is not reduced:

• Aircraft floats down the runway

• Landing distance increases

• Risk of runway overrun



Simple rule pilots learn:


“Flare… Retard… Touchdown.”
