FEATURES

Generative training environment.
Not a chatbot tutor.

GroundScholar focuses on the highest-leverage parts of pilot training. Each feature is grounded in the live FAR/AIM corpus with citation-backed explanations — not paraphrased summaries.

01 · STUDY PLAN

Personalized weekly plan.
Front-loads what you don't know.

Tell Reed your target certification, exam date, and weekly hours. He generates a week-by-week plan that front-loads weak topics, reinforces moderate ones, and trims time on what you've already drilled. Re-evaluated against actual mastery every week — fall behind and the schedule compresses; pull ahead and you start mock checkrides early.

SCENARIO · KAPA → KCOS
LIVE METAR
Crossing the Front Range, ceilings drop to 1,400 broken. You're at 9,500 MSL VFR, 60 miles from your destination. What's your move?
AContinue — terrain is well below
BClimb to 11,500, request flight following
C180° turn, divert to KAPA, file VFR flight plan
DSquawk 7700 and request IFR pickup
FAR 91.155Class E above 10,000 MSL needs 5 SM & 1,000–1,000–1 mile cloud clearance. Even a climb won't restore VFR if cloud bases drop further. The 180° divert is the conservative call DPEs reward.
FAR cite at every node
02 · BRANCHING SCENARIOS

100+ decision trees.
Live weather. Real consequences.

Hand-validated branching scenarios that drop you into a flight situation — VFR-into-IMC, fuel exhaustion, density-altitude trap, comm failure — and grade your decisions against the FAA's ACS. Real METAR/TAF data feeds the 'current weather' scenarios, so the same airport runs differently in winter vs. summer. Every option has a FAR cite to back the right answer.

Reed

“Your METAR shows 25 °C at field elevation 5,000 ft. What's the takeoff distance penalty, and which FAR makes you compute it?”

You

DA is roughly 8,200, so about 80% longer takeoff roll. FAR 91.103 makes preflight performance computation a legal requirement…

03 · ORAL EXAM SIMULATOR

Examiner Reed. Voice mode.
Adapts to your weak topics.

ElevenLabs DPE persona, OpenAI Whisper STT, sub-2s round-trip over WebSocket. Reed adapts difficulty per topic — confident answer on weight & balance? He moves on. Hesitant on icing certification? He probes deeper. Grades against ACS standards and debriefs at the end with the specific tasks you'd retake. Voice and text modes are both available.

04 · MOCK CHECKRIDE

Five-stage simulation.
Pass-prediction calibrated.

Five-stage practical test mirroring the FAA ACS — pre-flight planning, oral, pre-flight inspection, maneuvers, post-flight. Each stage hands off to the next with the same artifacts a real DPE would use (W&B sheet, METAR brief, navlog). Pass-prediction is calibrated against reported checkride outcomes — if Reed says you're ready, the data suggests you are.

How we keep it honest
Live eCFR verification

Every FAR citation is checked against the live eCFR before it ships in a question or answer. A post-LLM validator drops anything not in the corpus.

Hand-reviewed scenarios

Branching decision trees are written and reviewed by CFIs — not generated unsupervised. Each path's outcome traces to a specific FAR or ACS task.

Calibrated pass-prediction

Mock checkride scores are anchored to actual checkride outcomes from early users — not synthetic difficulty. We update the calibration as new data lands.
