Flaps up after landing with OAT >30 deg C

Recommended Posts

Can I make the PM retract the flaps all the way even with OAT above 30 deg C?(if not, can this be optional someday?)  

I‘ve been told that this procedure  becomes rarer as Airbus fixed the issue that leads to the „Wing air leak“ ECAM caution message. Most airlines seem to rectract the flaps completely regardless of the OAT.

Flaps up!  No point in picking up a fod hit.  In addition, if you pull up to the terminal with your flaps extended, you will probably be met by an armed response team because flaps down at that point is an indication of a hijack on board.

The other reason is when the flaps are down it locks the air conditioning packs on high. This causes the the aircraft to think it’s about to go flying.

The aircraft thinks this because generally it’s during a thru trip and the ADIRUS are still aligned. During most of the year depending on where the aircraft is operating from it does not matter due to temperatures. However an aircraft operating in Dallas Texas in summer with a ramp temperature of 120 degrees Fahrenheit it is an issue both inside the aircraft and outside.

By putting the packs on high it pulls a larger volume of air through the ducts helping to keep the duct temperature down. This may seam backwards but it’s not because the packs are pulling that air at a faster velocity through the ducts and doesn’t allow the air to slow down to transfer that heat to the ducts. The APU at this time doesn’t speed up or put out any more air. It was already commanded to 100% with any bleed air demand.

The most important reason for this is a bleed air duct leak in the wrong place may cause a fire onboard; hence why it is a no go item.

FCOM from an A320 (CEO, MSN 7xxx) :

If the approach was made in icing conditions, or if the runway was contaminated with slush or snow,  do not retract the flaps and slats until after engine shutdown and after the ground crew has confirmed that flaps and slats are clear of obstructing ice.
On ground, hot weather conditions may cause overheating to be detected around the bleed ducts in the wings, resulting in “AIR L (R) WING LEAK” warnings. Such warnings may be avoided during transit by keeping the slats in Configuration 1 when the OAT is above 30 °C.
To avoid damage on the RTLU (Rudder Travel Limit Unit) mechanical stop, the SLATS/FLAPS should be retracted before all ADIRS are set to OFF simultaneously.

No and no.  

We retract to CONF1 to allow for better airflow around the ducting and only retract as we approach the J-line.  We use to keep the slats out but encountered damage to the RTLUs and went back to retracting slats prior to J-line.

And you won't be met with an "armed response team" because only the slats are out.
