All pilots in Europe should undergo a psychological evaluation before entering commercial service.
That is a recommendation from the European Union air safety watchdog, after an investigation into the crash of Germanwings flight 9525 in March.
The European Aviation Safety Agency (EASA) also says two people should stay in a cockpit at all times, and that this principle "should be maintained".
It is also recommending that airlines should run a random drugs and alcohol programme, and that pilot support systems should be offered within airlines.
The task force concluded that improved medical checks on crews could bring a strong contribution to air safety.
The evaluation focused on medical and psychological assessments of pilots - including drugs and alcohol testing.
It also pointed at the need for a better oversight framework for aeromedical examiners.
"Concrete proposals"
"The report strives to reach a balance between medical secrecy and safety, and not to create additional red-tape for airlines", it says.
The European Commission will now review the recommendations, taking into account advice from other sources - such as the independent accident investigation led by the French Civil Aviation Safety Investigation Authority.
"Where legislative action is to be taken, EASA will be requested to develop concrete proposals, which will then be included in EU aviation safety regulations", the report says.
EASA will also be asked to produce non-legislative steps, such as guidance material and practical tools for information sharing, and to monitor actions taken by member states and the industry.
150 people on board a Germanwings flight were killed during the crash on March 24th.
Investigators have said that co-pilot Andreas Lubitz (27) deliberately destroyed the plane.
