The charity also had some crew members self-isolating so a decision was made to scale back night mission and possibly not even fly at all - at night - throughout May.
In a statement issued today (Friday) the charity said that crew members, including doctors, are now able to fulfil some shifts meaning there will be around 30% night-time cover throughout May.
CEO Karen Jobling said: “It was absolutely right that some of our doctors returned to support the NHS in coping with the Coronavirus where needed and we are so proud of these members of the LNAA team.
“We’re delighted that some of these clinicians are now able to come back to us and provide front-line, pre-hospital critical care that helps to saves lives across Lincs & Notts.
“We, like everyone else, are reacting to an ever-changing picture and doing our best to plan ahead but we remain alert to the fact that things are changing on a daily basis.
“We are on hand to provide mutual aid for neighbouring air ambulances where and when needed and remain committed to supporting the NHS in whatever capacity we can.”
Mrs Jobling revealed that the charity has launched a fundraising appeal due to a projected loss of £3m caused by Covid-19.
She said: We’ve had to close our shops and cancel vital fundraising activities which, over the spring and summer months, provide a significant boost to our income.
“Thank you to all of the people who have donated to LNAA.
“Without the generosity of the people of Lincs & Notts, we simply wouldn’t be able to carry out the life-saving work we do.
“You really do save lives and help to keep us flying.”
