Final answer:
The glideslope deviation limits are typically ± 0.7 degrees, and if exceeded, the pilot should not descend below localizer minimums and must consider executing a missed approach. Answer B) ± 1.0 degree; No is correct, indicating the pilot must not continue the descent if the glideslope limits are breached.
Step-by-step explanation:
The question asked is related to the approach phase in aviation, specifically when piloting an aircraft towards an airport for landing. The glideslope is an important component of the Instrument Landing System (ILS), which guides aircraft vertically to ensure a proper descent path. The localizer provides lateral guidance to align the aircraft with the centerline of the runway.
The limits for the glideslope deviation are typically ± 0.7 degrees. If an aircraft's approach falls outside of these limits, the pilot must consider going around and not continuing the descent. Answer B) ± 1.0 degree; No is correct in this context. The pilot should not descend below the localizer minimums if the limits are reached as it may not be safe to continue the approach due to being too far off the intended glide path.
Therefore, falling outside of the glideslope deviation limits is an indication that the aircraft is not aligned properly within the vertical path and the pilot should not continue descent but instead, execute a missed approach procedure. Safety is paramount, and adherence to these procedures is essential for the safety of the flight.
