I don't know about Aeroflot's or Airbus's manuals, but the takeoff in the video would have been a gross violation from my particular seat.
They don't differ from Boeing procedures on this matter:
A320 FCOM SUPPLEMENTARY PROCEDURES - ADVERSE WEATHER - COLD WEATHER:
EXTERIOR EXPECTION
[...]
SURFACES....CHECKED FREE OF FROST, ICE AND SNOW
All surfaces of the aircraft (critical surfaces : leading edges and upper surfaces of wings, vertical and horizontal stabilizers, all control surfaces, slats and flaps)
must be clear of snow, frost and ice for takeoff.
Thin hoarfrost is acceptable on the upper surface of the fuselage.
Note: Thin hoarfrost is typically a white crystalline deposit which usually develops uniformly on exposed surfaces on cold and cloudless nights; it is so thin that a person can distinguish surface features (lines or markings) beneath it.
SOP of Aeroflot part B (operation of A320):
COLD WEATHER AND FLUID RUNWAY CONTAMINATED OPERATIONS
EXTERIOR INSPECTION
[...]
SURFACES ... CHECKED FREE OF FROST, ICE AND SNOW
All surfaces of the aircraft (critical surfaces: leading edges and upper surfaces of wings, vertical and horizontal stabilizers, all control surfaces, slats and flaps)
must be clear of snow, frost and ice,
otherwise consider to perform de-/anti-icing. [
They even added this bit to reinforce that de-/anti-icing must be performed in this case ]
Note: Thin hoarfrost is acceptable on the upper surface of the fuselage and pilot can distinguish surface features (lines and markings) beneath it. Frost is acceptable on the underside of the wing tank area, a max layer of 3mm.
SOP of Aeroflot part A (General Procedures)
Written wholly in russian, it specifically states that if OAT is 6C and below, person charged with preparing acft for departure must check for hoarfrost or snow/ice deposits on all parts of acft. If found, then he orders de-icing procedure to remove these deposits. If OAT is below 15C, check for fuel frost and order de-icing if fuel frost present.
Just for the record, here is the original:
ИТП АТЦ, ответственный за подготовку ВС к вылету:
- при температуре наружного воздуха +15°С и ниже обязан проверить верхнюю и нижнюю поверхности крыла в районе расходных секций топливных баков на предмет отсутствия топливного льда (особенно при подготовке ВС к вылету при кратковременной стоянке после выполнения полета);
- при температуре наружного воздуха от +6°С и ниже, обязан проверить
отсутствие инея и снежно-ледяных отложений на всей поверхности самолета;
- при обнаружении инея или снежно-ледяных отложений на поверхности
самолета ИТП ответственный за подготовку ВС к вылету принимает
меры по их удалению, для чего заказывает спецмашину для проведения
процедуры удаления обледенения;
- по прибытию на ВС экипажа, ИТП докладывает КВС о результате
осмотра поверхностей самолета и о необходимости выполнения ПОО.
