If both the outside static vents and the pitot tube become clogged, which instruments would be affected? All air data instrument (Altimeter, VSI, Airspeed Indicator) would be adversely affected. Gyro driven instruments such as Gyro compass, and Artificial Horizon (AH) would not be affected as they do not use AIR DATA. Q10. The use of carburettor heat during takeoff and climb? Carb heat reduces density of charge in the cylinder and with it power, which adversely effects the takeoff distance and climb gradient. Q12. In the Southern Hemisphere, if an aircraft is accelerated, the magnetic compass may initially indicate? Use SAND rule. Apparent turn SOUTH for acceleration, NORTH for deceleration. Q21. Given: Pressure height = 5000 ft. OAT = ISA +10. CAS = 130 kt. TAS in these conditions is closest to? Refer circular Nav computer diagram at right! Note: ISA +10 temp at 5000 ft +15 C. Step 1. Set 5000 ft opposite temperature of +15 C ft +15 C Step 2. Read opposite 130 kt CAS the TAS of 142 kt. TAS 142 kt CAS 130 kt

Fixed reserve is 33 Litres and taxi fuel is 4 Litres. The minimum fuel required at start up at the departure aerodrome for this flight is closest to? Refer summary below! ITEM Amount (L) Flight Fuel (3 hours) 132 Fixed reserve 33 Taxi 4 Min Fuel at Start-up 169 L 140 kt Q23. Given: Area Forecast W/V = 150 /45 kt, TR(T) = 090. Variation = 10 E TAS = 140 kt. Determine the approximate HDG(M) and GS? TAS 080 M MC 39 kt 16 Refer diagram at right! Heading required with wind from the right is drift 16 = 096 M. Effective TAS 134 kt, so GS 112 kt (134-22) kt 39 kt 140 M Q25. Beginning of morning civil twilight (MCT) is found to be LMT for an aerodrome situated at E meridian. If LST at this location is quoted as UTC +10 hours, then MCT expressed in LST is closest to? 1. From AIP Gen 2 convert of arc to time. It is 9 hours 30 min. 2. UTC is Z. 3. Add Standard time difference of 10 hrs, so LST = LST.

Given the following details: Runway = 05/23 Take-off distance available (TODA) = 1300 metres Slope = level Surface = long wet grass, Pressure height = 3000 ft Wind = 250 M/15 kt Temperature = +15 C Take-off weight = 1050 kg The take-off distance required under the conditions given is closest to? TODR 1000 metres Slope Level Start HERE P/Ht 3000 ft + 15 C Short Dry Grass Long Wet Grass 1050 kg Start HERE 15 kt HEAD

The takeoff total moment/1000 is closest to? Summary Station Weight (Lb) BEW 1265 Oil 15 Pilot and front passenger (Row 1) 335 Rear row passengers (Row 2) 305 Baggage area 30 Fuel 37 US Gallons 222 Takeoff weight (TOW) 2172 ARM Moment/ Q42. Refer CAR (7) (D) Q43. VFG and ENR1.7 Q45. Given: Airport elevation 1700 ft. Temperature +40 C. QNH 1003 HPa. The airport density altitude is closest to? 1. QNH is 10 HPa out of ISA 10 x 30 ft/hpa = 300 ft. Pressure altitude is therefore 2000 ft. 2. Using 2 /1000 ft lapse rate, ISA at 2000 ft is +11 C. ISA deviation is 29 (40-11). 3. Density altitude (also called density height) correction is 29 x 120 ft/ = 3480 ft. 4. Density altitude is therefore pressure altitude + density height correction = 5480 ft. ANSWER! Q46. With a wind of 280 M@20 kt, the runway with the least crosswind/most headwind component is? 1. Plot this on your Circular Nav Computer. RWY 18 and RWY 13 obviously involve tailwinds so eliminate these with command thinking early on. 2. RWY 36 sees wind 80 degrees off the nose (mostly crosswind), but if you use RWY 31 wind is only 30 degrees off the nose. RWY 31 has greatest headwind/least crosswind. ANSWER! Q48. Katabatic winds move/strength compared to Anabatic winds. Memory aid: Cats come down from the mountains at night. A Katabatic wind is generally stronger than an anabatic wind because it has gravity on it s side.

You would expect the temperature at 9000 ft outside the cloud to be closest to? The temperature at cloud base will be about 4.5 C warmer than zero (3000 ft x SALR of 1.5 C/1000 ft) = +4.5 C. The lapse rate of the unsaturated air outside the cloud is 2.5 /1000 ft up to dew point. So 3000 ft x 2.5 = 7.5 cooler than at 6000 ft (+4.5 C) = -3 C. ANSWER! Q60. You are operating your VFR aeroplane in the PVT category. With its fuel tanks full, your aeroplane is said to have a maximum still air range, excluding 45 minutes fixed reserve at cruise consumption weight, of 510 nm, at 7500 ft, using 75% maximum continuous power. The TAS expected is 133 kt. The average fuel consumption at 75% METO is 11 GPH. The useable fuel capacity of your aeroplane is? nm/133 kt = hrs hours x 11 GPH = 42 gal (no reserve). 3. At 11 GPH the 45 minutes fixed reserve is 8 gal (rounded) gal + FR 8 gal = 50 gal fuel capacity. ANSWER! END OF PPL Exam 1 Working File.
