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 mode is in beta; text mode is live.

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 actual checkride outcomes from early-access pilots — 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.
