Which NAV channel preset is designated for KGTR ILS 18?

The designation of the NAV channel preset for KGTR ILS 18 being Channel 5 is based on the specific allocations made for various Instrument Landing Systems (ILS) at different airports. The allocation of channel presets is essential for pilots as it allows them to quickly tune their navigation systems to the correct frequencies needed for precise instrument approaches.

Assigning Channel 5 to KGTR ILS 18 enables the efficient use of radio frequencies, helping to minimize confusion and ensure safe operations during landing, especially in poor visibility conditions. Each channel corresponds to a specific frequency and is determined through regulatory frameworks that govern air traffic and airport operations.

The other channels are allocated for different ILS approaches or other types of navigational usage, thereby ensuring that each approach has a unique preset to maintain operational integrity and safety in air navigation. This specialized allocation is critical in preventing frequency interference and aiding in situational awareness for pilots during critical phases of flight such as landing.
