Who May Fly Solo
A flying club's standing instruction reads:
"A cadet may be cleared for solo flight only if all three of the following hold: (i) the medical is current; (ii) at least 15 hours dual have been logged; (iii) the check ride has been passed. The Chief Flying Instructor may waive condition (ii) alone, and only where (iii) is already satisfied and the waiver carries the CFI's signature. No other person may waive any condition."
Four cadets are put forward on the same morning:
- Ayaz: medical current; 14 h 30 min dual; check ride passed; CFI-signed waiver on file.
- Bilal: medical expired last week; 18 h dual; check ride passed; no waiver.
- Farah: medical current; 17 h dual; no check ride; a CFI-signed waiver on file.
- Daniyal: medical current; 12 h dual; check ride passed; a written endorsement from his own instructor.
Daniyal's instructor, who is not the CFI, argues that his endorsement should carry the same weight.
1. Decide each of the four cases strictly against the instruction, showing which condition drives each decision.
Read the worked answer
| Cadet | (i) Medical | (ii) 15 h dual | (iii) Check ride | Outcome |
|---|---|---|---|---|
| Ayaz | Yes | No (14 h 30) - but validly waived | Yes | Clear |
| Bilal | No | Yes | Yes | Not clear |
| Farah | Yes | Yes | No | Not clear |
| Daniyal | Yes | No (12 h) | Yes | Not clear |
Reasoning:
- Ayaz fails only (ii), and the waiver is valid: it is signed by the CFI and (iii) is already satisfied. The waiver reaches condition (ii) and nothing else. Clear for solo.
- Bilal fails only (i). No waiver exists for the medical in the instruction, so nothing can be done administratively - the medical must be renewed. Not clear.
- Farah fails only (iii). Her waiver is worthless here: the CFI may waive (ii) only where (iii) is already satisfied, and it is not. The waiver does not create a waiver of the check ride. Not clear.
- Daniyal fails (ii) and holds no CFI waiver. An endorsement from any other instructor is not a waiver, because the instruction says no other person may waive any condition. Not clear.
2. Farah's file already contains a CFI-signed waiver. What is the minimum that must change before she can be cleared, and what is the trap in her case?

Minimum change: she must pass the check ride. Nothing else is missing - medical is current and she already has 17 dual hours, so once (iii) is satisfied the waiver becomes live if the waiver is intended to cover the dual-hour condition (which she does not actually need, having 17 hours).
The trap: the signed waiver looks like permission and is easy to read as "Farah is cleared". But the waiver is conditional. Its precondition - (iii) already satisfied - fails, so the document has no effect whatsoever. A signed piece of paper is not an authority; it is an authority only within the conditions written into the rule that created it.
Practical point for the morning's flying: Farah cannot fly solo today, and the CFI's signature does not change that. The correct action is to schedule the check ride, not to rely on the waiver.
3. A visiting instructor says: "The rule lists three conditions, so a cadet who meets all three is entitled to solo." Explain what is wrong with that reading and construct a case where the three listed conditions are met but solo still may not be permitted.
Read the worked answer
The error is confusing necessary with sufficient conditions. The instruction says "only if", which makes the three conditions necessary: no one solos without them. It does not say "if", so it never makes them sufficient. Meeting all three removes the obstacles listed in this one instruction - it does not grant a clearance. A clearance still has to be given by someone with the authority to give it, and other standing rules may also apply.
Constructed case: a cadet with a current medical, 20 dual hours and a passed check ride who has not flown for 60 days. All three listed conditions are satisfied. If squadron standing orders require a recency flight within 30 days, or a dual check in the last 14 days, that cadet is still not permitted to solo - the three conditions were necessary and were met, and were still not enough.
Why it matters in the air force: reading "only if" as "if" converts a safety filter into an entitlement. The safe habit is to ask both questions - does he meet every stated condition? and is there any other rule that also applies?
