The QT version of the interview.
Qatar Interview Profile SIM Airbus 330 or sometimes 320. 1. Depart LHR RWY 27R or it could be RWY 34 DOHA. 2. Straight out departure, sometimes the instructor will let you do some general handling, sick as steep turn, climb, descent so you get a feel of the airplane. 3. But most of the time they will immediate vector you for an ILS to land. 4. You will be lined up for takeoff again, and this time you might get an engine failure before V1. 5. Then you get a fire on the a/c, ask for memory items. 6. Request mayday, do the after T/O checklist, ask for rest of checklist. 7. Let the pilot non flying inform cabin crew and packs, quickly back request short vectors and fire guys to be ready when you land. 8. Do a briefing about evacuation etc. 9. Be aware for GS interception, since you might approach at a lower alt for the ILS. 10. The sim usually takes around 30-45 minutes.

Interview Question Bank 1. How does a pressure altimeter work? a) Air pressure is highest at Earth\'s surface and gradually falls, in a systematic way, the higher up you go. Measuring the air pressure is therefore (in theory, at least) a simple and effective way of measuring altitude. b) The altimeters onboard most planes are actually aneroid barometers (pressure-measuring instruments) that have been calibrated (marked with a scale) so they show height inside of pressure. Like normal aneroid barometers, they consist of a hollow, sealed box that expands (as the pressure falls) or contracts (as the pressure rises). As the box changes size, by very tiny amounts, an intricate system of levers and gears magnifies its movements and makes a pointer rotate on a dial marked with height measurements. Hey presto, tiny changes in air pressure become accurate measurements of altitude. 2. Give definition of QNH,QFE? • QNH is the barometric Above Mean Sea Level (AMSL) pressure in Hectopascals. On this setting, the aircraft altimeter reads altitude. QFE is corrected for altitude pressure at the airfield, on this setting the altimeter in the aircraft reads Feet AGL (Above ground level). (Usually above the highest fixed point on the runway) 3. How does weather affect altimeter setting? 4. Altimeter instrument errors? a) Position Error: In some installations, position error can be of considerable magnitude. b) Scale Error: Commonly referred to as instrument error, scale error is caused by the aneroids not assuming the precise size designed for a particular pressure difference. This error is irregular throughout the range of the instrument (it might be -30 feet at 1,000 feet and +50 feet at 10,000 feet). The tolerances for this error became larger as the measured altitude is increased. c) Mechanical Error: Mechanical error is caused by misalignment or slippage in the gears and linkage connecting the aneroids to the display, or in the shaft of the barosetting knob. d) Density Error.- ICAO Standard Atmosphere conditions seldom prevail, and the resulting density error is only
partially offset by the diligent application of correct altimeter settings (station or standard pressure). It can generally be disregarded for Air Traffic Control purposes, since all pressure altimeters in close proximity react in the same way, and vertical separation is maintained. e) Hysteresis: This error is a lag in the altitude indications caused by the elastic properties of the materials used in the aneroids. It occurs when an aircraft initiates a large, rapid altitude change or an abrupt level-off from a rapid climb or descent. It takes a period of time for the aneroids to catch up with the new pressure environment; hence, a lag in indications. This error has been significantly reduced in modern altimeters and is considered negligible at normal rates of descent for jet aircraft. f) Reversal Error: During abrupt or rapid attitude changes, reversal error occurs; it is only momentary in duration.
5. Static variation in pitot tube causes error and is called? 6. How to calculated true altitude at an airport? • True altitude is your actual height above sea level. If you set the altimeter to local pressure corrected to sea level, indicated altitude is approximately true altitude. 7.

What happens to your indicated airspeed if the static vent is blocked at the start of a climb? • Airspeed indicator will show inaccurate reading. 9.
