OP 201-250

Concerning the operators of complex organisations- who is responsible for (flight) safety?

• The safety manager and a safety review board.

• The safety manager and the chief pilot.

• The safety manager and the chief executive.

• The owner of the company.

Is refuelling permissible when passengers are on board, embarking or disembarking?

• It is permissible.

• It is permissible when relevant precautions are taken except when using AVGAS or wide-cut fuels.

• It is not permissible except when using wide cut fuels or AVGAS.

• It is permissible only as long as the passengers remain on board.

When is the oxygen required to be supplied for the crew and 100% of the passengers in an unpressurised aircraft (EASA AIR OPS regulations)?

• The entire flight time at pressure altitudes above 10 000 ft.

• The entire flight time at pressure altitudes above 11 000 ft.

• The entire flight time at pressure altitudes above 12 000 ft.

• The entire flight time at pressure altitudes above 13 000 ft.

In the absence of wind and without the astronomic precession effect, an aircraft would, at a constant gyro heading, follow a:

• great circle line.

• rhumb line.

• spherical flight segment.

• straight map line.

During Low Visibility Take-off Operations, the reported RVR for the initial part of the takeoff run is below limit. The take-off:

• is not possible under any circumstance.

• is possible provided the captain can visually assess the actual RVR and it is at or above the limit.

• is possible provided the aircraft is equipped with an approved lateral guidance system or HUD (Head-Up Display).

• is possible if high intensity runway centre line lights spaced 15m or less are operational and both pilots are licensed to perform LVO CAT-Ill operations.

What are the autopilot minimum requirements in order to fly single pilot operations in IFR conditions or at night?

• Two axis autopilot with altitude hold and heading hold.

• Two axis autopilot with altitude hold, heading hold, VOR tracking and Alt acquire.

• Single axis autopilot with altitude hold only.

• Single axis autopilot with heading select and VS.

A check on the operation of the SELCAL equipment during a transatlantic flight using the OTS (Organised Track System) must be done:

• at or prior entering the oceanic airspace.

• prior entering the NAT region.

• on ATC request only.

• within 15 minutes after crossing the oceanic airspace boundary.

Special categories of passengers or persons with reduced mobility (PRMs) should be allocated seats:

• next to emergency exits as there is more room available.

• that are not next to emergency exits as they could obstruct access.

• next to the galley.

• wherever they prefer.

Who must finally determine that the load and its distribution is such that the mass and balance limits of the aircraft are not exceeded and confirm their acceptance by countersigning the mass and balance documentation?

• The operator.

• The commander.

• The flight engineer.

• The airline's dispatcher.

The minimum RVR for a Category III B operation with roll out guidance or fail passive control systems is:

• 50 m

• 75 m

• 125 m

• 200 m
