IFR2.2 Basic VFR/IFR Maneuvers

Question 1

IFR.2.2.1 Vertical S’s

1. What are the altitude changes and at what cruise speed?
2. What rate do we have to keep?
3. By how much do we anticipate the maneuver?
4. How will the turns be?

Answer 1

1.Altitude changes: 400, 300, and 200 fts at medium cruise speed
2. 500 ft/min
3. about 20-40 ft
4. turns will be coordinated (3 degrees per second)

Question 2

IFR2.2.2 Timed Turns

1. What do we want to achieve in coordinated timed turns?
2. What are the conditions to a timed turn?
   
   • How many degrees per 15 seconds?
   • Angle of bank?
   • Delay? how long do we need to recover?
   • Antipacion?
   • What’s the formula to calculate our angle of bank if our turn coodinator is inoperative?

Answer 2

1. 360º turn in 2 minutes

• Every 15 seconds, 45º
• Angle of bank musn’t be no less than 10º and not more than 30º
• About 7º on initial turn until we reach the correct angle of bank, so we need to recover this 7º during the coordinated turn
• Anticipate to finish the turn with the number of degrees equal to 1/3 of the bank angle set
• α = (TAS/10) + 7

Question 3

IFR.2.2.3 Timed Climbs/Descends

• Cruise speed and rate of climbs/descends?
• How much should we have climbed or descended every 15 seconds?
• How should you correct if observing delay or advance in indication?

Answer 3

• Medium cruise speed of 120 kts and 500 ft/min
• In every 15 seconds, 125 ft
• Correct using throttle and control column to be on the proper position for the 15 second’s check

Question 4

IFR2.2.4 Spirals

• What’s a spiral?
  -What’s the configuration for a spiral?
• How often and what do we need to check?
• What has priority?
• How should you correct if observing a delay or an advance?

Answer 4

• Complete turn of 360º turn in 2 minutes and climb or descend during the turn.
• Medium cruise and rate of 500 ft/min
• Check every 15 seconds that we have turned 45º and climbed or descended 125 ft.
• Vertical speed has priority over airspeed
• Using throttle and control column ir order to correct the delay.

Question 5

IFR.2.2.5 Reversal maneuvers

What are they used for?
What types of turns are there? What’s their timing and category?

Answer 5

• Make a 180º turn controlled on IFR flights
• 45º/180 procedure turn:
  Timing:
  1-3 minutes outbound after passing a station or start the turn defined by a fix.
  Then turn left 45º and follow that heading for 1min and 15secs
  Then turn 180º right to intercept inbound
  Category:
  C,D & E
• 80/260º procedure turn
  Timing:
  1-3 minutes outbound after passing a station or start the turn defined by a fix.
  Then turn left 80º and then 260º right to intercept inbound
• Base turns
  Timings:
  Over the station turn to the left 45º, 60º and 80º, and then fly for 1, 2 and 3 minutes respectively on that heading
  Then turn to the right at the end of outbound leg defined by a radial or DME distance from a suitably located facility
• Racetrack procedures
  For the start of timing, see 3.3.5
  After passing the station inbound, turn right 180º, when passing station head outbout 1,2 or 3 minutes, then turn right again 180º to intercept inbound.
  The end of the outbound legt is limited by a radial or DME distance from a suitably located facility.
