Applying Storage Status to In Service Aircraft
The Covid-19 (coronavirus) pandemic has had a significant impact on the normal utilization of airline fleets worldwide, with aircraft needing to be transitioned from "In Service" to "Storage" Status in Fleets Analyzer to reflect this. Our normal methodology is to detect at least 2-weeks of non-activity in order for a specific airframe to qualify for the application of Storage Status.
However, during peak reduction in air transport operations (Feb - 26th Apr 2020) we tightened the qualifying window to 7 days, reflecting the rapid groundings by operators around the world and enable our customers to see an accurate view of the “storage landscape”.
For fleets that are known to be 100% grounded, we can always apply Storage sooner than the 7-day rule. Additionally, we can determine storage for particular aircraft more quickly than 7-days by looking at other triggers such as ferry flights to airfield storage management facilities.
Effective Monday 27th April 2020, we adjusted our qualifying period for aircraft being in storage from 7 consecutive days back to the normal 14.
Aircraft returning to service
We are now starting to see some aircraft return to operational service, particularly in Asia, and our criteria for updating our fleets data is as follows: an aircraft is considered to be in-service once we see flight activity on at least three of the preceding seven days, in addition, we will also accept five out of the preceding 14 days in recognition that a significant proportion of the fleet is seeing regular but highly sporadic utilisation.
The reason we have set the tolerance at 3 days is to avoid any confusion over one-off repatriation or cargo flights that are occurring globally and seem to be very ad-hoc in their nature thus not reflecting true operation.
As ever, if you have any questions around this data then we encourage you to get in touch via the “Email Support” link that can be found on the Fleets Analyzer homepage.
