1. (Refer to figure 033-14) Planning an IFR flight from Paris to London for the twin jet aeroplane. Given: Estimated Takeoff Mass (TOM): 52.000 kg Airport elevation: 387 ft Cruise: FL280 W/V: 280°/40 kts ISA Deviation: -10 °С Average True Course: 340° Find fuel to the top of climb (TOC).
2. On IFR navigation chart, in a 1° quadrant of longitude and latitude, appears the following information: “80”. This means that within this quadrant:
3. (Refer to figure 033-14) Find still air distance (NAM) and ground distance (NM) for the climb. Given: Brake release mass: 57.500 kg Temperature: ISA -10 °С Headwind component: 16 kts Initial cruise: FL280
4. On a given path, it is possible to chose between four flight levels (FL), each associated with a mandatory flight Mach number (M). The flight conditions, static air temperature (SAT) and headwind component (HWC) are given below: FL370 M 0,80 Ts: -60 °С HWC: -15 kts FL330 M 0,78 Ts: -60 °С HWC: – 5 kts FL290 M 0,80 Ts: -55 °С HWC: -15 kts FL270 M 0,76 Ts: -43 °С HWC: 0 The flight level allowing the highest ground speed is:
5. An airway is marked FL80 1500 a. This indicates that:
