You get a message from the destination airport that they need 20 minutes to complete snow removal. The fuel consumption during the hold is 2 400 kg/hour. The final reserve fuel and the alternate fuel together must be at least as much as the fuel during the hold plus the fuel to the destination. How much fuel do you need on board if your consumption to the destination is 20 kilograms per mile, and the destination is 150 miles away?

• 8.2 tons.
• 7.6 tons.
• 8.4 tons.
• 3.8 tons.

The remaining fuel in the tanks of your aircraft is 190 litre (left tanks) and 450 litre (right tanks). For the next flight, you need a total amount of fuel of 900 liters. How many kg of Kerosene are you going to tank (specific gravity 0.8 kg/l)?

• 288 kg.
• 208 kg.
• 720 kg.
• 325 kg.

You fly a VFR cross country flight, you chek the time between two turning points, to determine ground speed. The distance and time of the leg are 45 NM and 11 minutes respectively. What is your ground speed roughly?

• 495 kt.
• 240 kt.
• 270 kt.
• 240 km/h.

You fly with 2 NM right offset parallel to the track. ATC advises you to return to the track at the distance of maximum 10 NM. You will change your heading:

• 12° to the right.
• 12° to the left.
• 6° to the right.
• 6° to the left.

The fuel flow of a twin-engine aircraft is 17 kg/min per engine. You need to keep 1 200 kg for final reserve and 1 100 kg for alternate fuel. How much extra time do you have, if your current fuel on board is 7 700 kg and the remaining trip fuel to the destination is 4 200 kg

• 35 minutes.
• 43 minutes.
• 41 minutes.
• 30 minutes.

Your aircraft needs 0.6 kg fuel per second during flight. Speed of flight is 500 KT. Destination is 750 NM away, and the final reserve fuel and alternate fuel together must be as much as the fuel for consumption. How much fuel do you need on board?

• ≈ 6.0 tons.
• ≈ 6.5 tons.
• ≈ 5.0 tons.
• ≈ 4.5 tons.

• 96 NM.
• 140 NM.
• 108 NM.
• 100 NM.

You fly a Zlin Z-142, and the speed indicator shows 180 km/h (assumed to be TAS). Based on the fuel on board (plus reserve fuel), the endurance is 0:42. What is your range in still air conditions?

• 120 km.
