5.17. Missed Approach

[In this section we have used "Go Around" as the standard call to initiate a missed approach. "Go Around" is used because it applies to the mode of display and operation of several flight guidance systems associated with missed approach procedures. Use of other terms such as "Overshoot" or "Missed Approach" are completely acceptable. However, we do recommend the use of terminology that is consistent with equipment in your aircraft.]

[To the extent practical specify missed approach procedures that are common for all or most types of missed approaches. Also, attempt to make most elements of the missed approach similar to those for a take-off.]

  1. General - During some approaches it will become inadvisable to continue for landing. Should this occur, a missed approach should be initiated. Guidance for specific conditions when a missed approach should be initiated is detailed throughout these SOPs. Such guidance cannot address all circumstances. Accordingly, either pilot should initiate a missed approach whenever a landing becomes inadvisable.
  2. Common Procedures - The procedures to execute missed approaches from most situations are comprised of common elements. Although some requirements will differ, such as navigation, the basic procedure is standard for all missed approaches. In all cases a missed approach is initiated by one of the pilots using the standard call "Go Around" which is immediately responded to by the other pilot with "Check." If Full Flap has been selected, the standard call is modified to "Go Around, Flaps Approach." The PNF would respond similarly with "Check" and selecting the flaps from full to Approach. The remaining procedures and crew coordination for a missed approach are described in the following table.

[The following checklist is a guide only and cannot apply to all aircraft. The checklist particular to the aircraft must be inserted here]

Table 5-2 Missed Approach - Procedure and Crew Coordination
Select Go Around on the Flight Director.
  • Call "Go Around", or if appropriate call "Go Around, Flaps Approach."
  • Acknowledge with "Check" and if appropriate confirm that the minimum speed is Vfri and select flaps to approach.
Rotate the aircraft at a rate of about 2o per second until the pitch attitude approximately matches the Flight Director command cue. Simultaneously advance the power levers toward the power setting briefed for the missed approach. If a power setting other than as briefed is appropriate, call for the required power.  Tap the PF's hand from below and simultaneously advance the power levers and propellers to the setting briefed for the missed approach or to the power setting called for by the PF.
When the PNF taps the PF's hand from below the PF should place both hands on the control yoke to indicate understanding that engine power is being handled by the PNF. Confirm that the aircraft is climbing as indicated by the altimeter, the VSI and, if possible visually. If the aircraft is in fact climbing:
  • Call "Positive Rate."
At the "Positive Rate" call, confirm a climb on the VSI and visually (if possible). If climbing:
  • Call "Gear Up" and give the visual signal to retract the landing gear.
Select the landing gear up. Select Heading as the lateral mode on the Flight Director and select Altitude Select to arm the Flight Director altitude capture mode. Confirm the Flight Director selections on the advisory display and, if successful say nothing. If not successful briefly indicate the fault. Monitor gear retraction. If gear retraction is normal say nothing. If there is a malfunction call "Unsafe Gear".
If the PNF advises that a landing gear malfunction has occurred do not exceed ____ KIAS. Retract flaps on schedule, climb to at least 1000 ft AGL and refer to the appropriate abnormal procedure check.  
Climb at a speed of at least V2 + 10 KIAS (if all engines are operating normally). At a safe altitude that is at least 400 ft above the departure runway accelerate to Vfri then:
  • Call "Flaps Up", and give the visual signal to retract the flaps.
Confirm that the aircraft speed is at least Vfri then select the flaps up, select IAS as the vertical mode of the Flight Director:
  • Call "IAS Selected".
Call for any changes to NAVAID set up.  Action any NAVAID changes.
Adjust the IAS using TCS or call for the PNF to set a particular speed using the thumb wheel. Do not exceed ____ KIAS until the Gear Up, Flaps Up call. When flaps have fully retracted re-confirm that the gear is up:
  • Call "Gear Up, Flaps Up".
When the PNF calls "Gear Up, Flaps Up", if Take-off Power is no longer required:
  • Call "Set Climb Power" and give the visual signal to reduce to climb power.

(If other than standard power is required at this point call for the specific power required, ie. "Set Max Continuous Power.")

Select the bleeds to ON and MAX. Then reduce to climb power or as directed and select the synchrophase on.
Follow the published/cleared/circuit missed approach. Climb to the missed approach altitude or circuit/cleared altitude:
  • Call "After Take-off Check" or the "Downwind Check" if applicable.
Carry out either the "After Take-off Check" as detailed in the Normal Flight Procedures Departure chapter, or the "Downwind Check" as detailed in the Normal Flight Procedures Arrival chapter.

[If your aircraft or operation can make use of additional guidance for missed approaches under specific circumstances (ie. Category II ILS) detail them as separate procedures/tables or as text in the form of differences from common procedures.]
