OK. If I understand correctly, it means he’s flying like sideways.
This is perfectly normal with crosswind. The stronger the crosswind, the more he will fly “sideways”. We sometimes fly with very strong crosswinds (25-30kph) and he flies with almost 45 degrees angle. We always check the windspeed during the flight and if it is above 35kph, we abort the mission.
I worry less with pure headwind or tailwind, What you loose in groundspeed with headwind is what you win with tailwind. But crosswind affects both directions and sometimes drastically reduces your flying distance.
Also bear in mind that wind speeds can differ a lot, depending on altitude. It can be totally calm on ground zero and have strong winds at your mission altitude,
Hope this helps.
