Dragonfly ========= Scenario -------- You are the pilot of a light aircraft on the runway at Norwich airport. You have been given clearance to fly a circuit and land back at Norwich or to fly south down to Hethel and land there. There is a radio beacon at Hethel and this will guide you on either flight. Flying A Circuit ---------------- When the program is first run you are stationary on the runway at Norwich. To start taxing, increase power up to the maximum of 3,000rpm, the stall light will flash until your airspeed is sufficient for you to take off safely. Raise the nose one point and then the undercarriage. Raise the nose further and notice your altitude increase and the positive value of your verticle speed indicator. Having attained an altitude of about 100ft, continue to climb and put on two lots of right bank. Notice the artificial horizon indicate the bank. Continue banking until your heading is indicating 180 degrees. With small adjustments, alter your heading until the bearing to the beacon is steady. When your altitude is above that of the highest mast in the area, 585ft, bring the nose down to level and reduce rpm to 1,500 to maintain level flight. Watching your distance measuring equipment (DME) you will notice you are closing in on the beacon. Norwich airstrip is 10 miles from the beacon, so allow yourself to get within 6-7 miles of the beacon and then bank right to bring your heading round to 360 degrees and the bearing from the beacon to 179 degrees. This is the bearing of the runway. Reduce engine rpm to 500 or 1,000 and lower the nose to reduce height. The instrument landing system (ILS) indicates whether you need to bank left or right to obtain a bearing of 179 degrees, remember to straighten up on to a heading of 360 degrees, or you will fly across the line, not along it. *When you are lined up* with the ILS a horizontal bar will appear, this indicates the position of the ideal glide slope relative to the aircraft. Reduce engine rpm to 500 and wait for your airspeed to drop below 125. Lower the flaps and undercarriage, and you are now set up to land. Adjust flaps, nose and rpm to remain on the ideal glide slope (horizontal bars either side of the 'I'). When you see the runway lights and your altitude is below 40ft, put the aircraft nose in the level position and reduce rpm to zero. You should now descend onto the runway and taxi to a halt. Flying Down To Hethel --------------------- Take off and obtain a heading of 180 degrees as before. As you get close to the beacon at Hethel (within 1.5 miles), the bearing will become nonsensical. Continue on a heading of 180 degrees and the bearing will settle down. Once you have passed the beacon, the DME wil give a positive reading as you fly away from the beacon. Continue flight until you are 2 to 3 miles past the beacon, bank right and obtain a heading of 359 degrees and a bearing of 359 degrees. Land as before, but note there are no lights at Hethel. Note ---- When close to beacon: BRG & DME are inaccurate. The bearing to beacon from Norwich A/F is 179 degrees. The bearing to beacon from Hethel A/F is 359 degrees. Engine stops if A/C is inverted. Restart in normal manner. All headings given assure Zer wind velocity greater than zero has been input, choose a heading to maintain desired bearing. Aerobatics ---------- Loops, rolls and inverted flight are possible, but note that the engine stops if the aircraft is inverted and needs to be started in the normal way. Wind ---- The wind blows from 280 degrees in strength from 0 to hurricane.
