300 reference questions on the lighting that guides an aircraft down the final approach: approach lighting systems, PAPI, APAPI, VASI, REIL, visual approach guidance and runway alignment, with the fault-finding, inspection and compliance thinking behind each.
Every question traces back to one of seven approach and visual guidance topics, from approach lighting systems through PAPI, APAPI, VASI and REIL to visual approach guidance and runway alignment. The bank leans toward working-engineer depth, with troubleshooting and scenario questions alongside the definitions.

Short answers about the approach and visual guidance question bank, how the drill and scoring work, and the core systems it covers.
It is a 300-question reference and drill on approach lighting systems, PAPI, APAPI, VASI, REIL, visual approach guidance and runway alignment. Every question has a model answer, an explanation and tagged key terms, and the whole bank is searchable, filterable and drillable on this page.
Seven topics: Approach Lighting Systems (80), PAPI (50), APAPI (30), VASI (30), REIL (25), Visual Approach Guidance (40) and Runway Alignment (45). Each topic can be opened pre-filtered from the topic chips or the filter pills in the explorer.
Three levels: Beginner (43), Intermediate (161) and Advanced (96). About 86% of the bank is Intermediate or above, so it leans toward working-engineer depth. If terminology is still new, start with the Beginner filter, or with the AGL Fundamentals bank.
Technical explanation (206), scenario-based (35), multiple choice (26), troubleshooting (21), interview-style (9), short answer (2) and maintenance (1). Fault-finding, scenario and interview-style questions probe how you diagnose, inspect and justify decisions on approach and visual guidance systems, not just what you can define.
Drill Mode gives a shuffled run through the bank, filtered by level and topic if you choose. Type your own answer and check it, or just reveal the model answer. Multiple-choice cards are answered by picking an option. Typed answers are marked with weighted key-term matching (with stemming and typo tolerance) plus overall wording overlap. It is a close local approximation of a marker, not true AI grading, so use it to spot gaps rather than as a formal assessment.
An approach lighting system extends outward from the runway threshold and gives the pilot visual references for alignment, height perception and roll cues during the transition from instrument to visual flight. The bank covers how those systems are configured, how they relate to the runway lighting, and how they are inspected, maintained and troubleshot.
PAPI uses a single wing bar of four sharp-transition light units, and the pilot reads how many appear red or white to judge position against the approach slope. APAPI is the abbreviated form with two units. VASI uses two or three light bars and the pilot compares the colours of the bars. All three are covered in their own topics, including installation, alignment, photometry and fault-finding.
REIL are a pair of synchronised flashing lights, one on each side of the runway threshold, that give quick, positive identification of the approach end of a runway, especially where it is hard to pick out against surrounding lights. The bank has 25 REIL questions, from purpose and configuration to synchronisation faults and acceptance.
The 45 Runway Alignment questions cover how approach and visual guidance systems relate to the runway and the approach path: the purpose of alignment, how obstacles affect visual alignment, and the survey, commissioning and photometric checks that confirm the installation does what the design intends.
Answers are framed against ICAO Annex 14 (referenced in 131 questions) and FAA publications, most often AC 150/5340-30J (124), AC 150/5345-28H (40) and AC 150/5340-26C (56), plus the FAA AIM Chapter 2 (56). Many answers are deliberately worded as subject to the applicable standard, so always check the current edition that governs your project.
Yes. Alongside 9 interview-style questions, the 21 troubleshooting and 35 scenario questions mirror how technical interviewers probe fault-finding, alignment and compliance judgement on approach and visual guidance systems.
These 300 questions test what you already know about approach and visual guidance lighting — Precision AGL Academy is where the gaps they surface get turned into working technical skill.
