In most cases, the rotational speed of a jet engines must be increased, or "spooled up" before it will start to produce thrust. During a baulked landing, as per the criteria listed above, the engines are at idle and the airspeed can be below V ref and is decreasing. These actions presuppose a normal approach energy state with engines above idle and speed at or, more frequently, above V ref. retracting the flaps to the appropriate go around setting.rotating the aircraft to the appropriate go around pitch attitude (follow the flight director where certified).At night or in IMC conditions (and under VMC conditions under some circumstances), this can pose an extreme risk of CFIT.įor most aircraft, the standard actions for initiating a normal go around include simultaneously: As illustrated in the diagram below, this can potentially compromise obstacle clearance. This can further increase the risk, especially in the event that the pilot elects to abandon the go around and, instead, try to salvage the landing.īy definition, a baulked landing is initiated well below and far beyond the Missed Approach Point (MAP) associated with any instrument approach procedure for the landing runway. As previously indicated, touchdown may occur after a baulked landing has been initiated. There are two primary, but critical, risks associated with a baulked landing: initial aircraft performance and climb capability due to the low energy state inherent to the baulked landing regime, and obstacle clearance, especially in IMC conditions. any other circumstance that leads the pilot to believe that a safe landing cannot be achieved.Runway Incursion by another aircraft or a vehicle.strong and/or excessively gusty crosswinds.a long landing as might occur after an excessive float or during Tailwind Operations.loss of visual references as might occur in shallow fog (MIFG), blowing snow (BS), or, during night operations, in the event of power failure induced loss of runway lights.These circumstances might include any of the following: That decision can be precipitated by a number of different circumstances. DecisionĪ baulked landing is, in essence, a last minute go around decision. A given aircraft may enter the low-energy (baulked) landing regime either above or below 50 feet based on the approved landing procedures for that specific aircraft type. Note that 50 feet is a representative value. aircraft height 50 feet or less above the runway. aircraft flaps and landing gear in the landing configuration.The low-energy, or baulked landing regime is defined by Transport Canada as: An aircraft is not certified to successfully complete a go around without ground contact once it has entered the low-energy landing regime, that is, during a baulked landing. It is a common belief amongst aviation professionals that aircraft are certified to successfully complete a go around from any point during the approach or landing phase. The Aircraft Flight Manual (AFM) defines the limitations within which the aircraft may be safely operated. Criteriaĭuring the certification process for any aircraft, performance and handling are assessed across a wide range of weights, configurations, and flight profiles. Whilst the two definitions are very similar and the obstacle clearance considerations for both are virtually identical, it is the initial climb performance aspect of the baulked landing definition that is the focus of this article. The term is often used in conjunction with aircraft configuration or performance assessment, as in Baulked landing climb gradient. Baulked Landing: A discontinued landing attempt.If related to the consideration of aircraft configuration(s) or performance, it is sometimes referred to as a Baulked Landing. A rejected landing typically results in a missed approach. A rejected landing may be initiated in either visual meteorological conditions (VMC) or instrument meteorological conditions (IMC). A rejected landing typically is initiated at low altitude but prior to touchdown and typically is initiated below DA(H) or MDA(H) of an IAP. Rejected Landing: A discontinued landing attempt.Transport Canada defines the terms rejected landing and baulked landing as follows: However, some National Aviation Authorities (NAA) have defined the terms and have established training/checking requirements to encompass these events for operators under their jurisdiction. Universal definitions of the terms baulked landing and rejected landing have not been adopted. A baulked landing, although rare, is considered a high-risk manoeuvre. In virtually all cases, the go-around is initiated whilst the aircraft is in a decreasing energy state. A Baulked Landing, sometimes referred to as a Rejected Landing, is a low energy go-around initiated from a very low height above the runway or, potentially, even after touchdown has occurred.
